Why Manure Is Better Than Fertilizer
- November 2, 2021
Dairy Forage Research Center at Madison, Wis., offers a list of the benefits from manure that you can’t get from chemical fertilizers.Whether a producer needs to supplement the nitrogen in manure with commercial fertilizer depends on the ratio of land to animals.“So there needs to be some supplementation either through purchased fertilizer, or through legume crops that can fix a fair amount of nitrogen and leave it in the soil.”.“There were questions,” he says, “because most of the dairy states in the Midwest recommend that you don’t apply any nitrogen, except perhaps starter, in the first year of corn after alfalfa.But farmers and their advisors were asking, “With our much higher yields of corn—when we’re talking, not about 130 or 150 or 180 bushels per acre, but about 200 or 250 bushels per acre—is it still true that alfalfa can provide all the nitrogen?” So far, the research shows that if you have an alfalfa stand of at least four plants per square foot, there is plenty of nitrogen for the next corn crop, even with yields exceeding 200 bls.But if you’re cutting a corn crop for silage, there’ll be a lot of potassium in there.” Phosphorus applications, though, need to be managed carefully, using the recommendations developed by each state.“We’re facing situations where neighboring freshwater streams or lakes have Total Maximum Daily Load regulations for phosphorus,” he says.If manure is kept in liquid form and applied properly—that is, by injection or by incorporation within a couple of hours of application—the amount of nitrogen it will provide can be predicted fairly precisely.Russelle says even when exposed to sunlight and drying conditions on plant surfaces, many pathogens can live from six months to a year.In a research paper, Contributions to Society: Manure-Fertilizer/Fuel, Developed Countries, he talks about how it may become more important to conserve the nitrogen in manure if energy costs continue to rise, and will also reduce CO² greenhouse gas generation by displacing manufactured fertilizer. .
Manure Better than Inorganic Fertilizer, According to New Study
The study, Response of Soil Organic Carbon, pH, Electrical Conductivity, and Water Stable Aggregates to Long-Term Annual Manure and Inorganic Fertilizer, was recently published in Soil Science Society of America Journal.The results of this study could further bolster the growing movement toward utilizing manure more effectively.Soil pH.The study found that over time, the application of manure was able to maintain soil pH in a suitable range for crops, while inorganic fertilizers actually caused the soil to become more acidic.Here again, manure proved to increase the SOC in the studied soils.The study also showed that manure increased water-stable aggregates in the soil.Another challenge that farmers must grapple with is the unpleasant odor emitted by manure – an odor that can be a problem for neighbors and the surrounding community.Granulation processes manure into a premium fertilizer product – the formulation of which can be customized to meet on-farm or regional nutrient management requirements.The opportunity for nutrient runoff is reduced, because the use of a granular product makes following a nutrient management program much easier.Because they are dry, transporting granules away from the farm also becomes a much more viable option.As a result, specialty fertilizers that utilize both organic and inorganic materials are becoming the new normal; by combining the benefits of manure with a controlled nutrient formulation, growers can maximize crop production and nutritional quality.Combined Inorganic and Organic Fertilizer Product Development.The combination of both inorganic and organic fertilizer products is quickly becoming a booming trend in the fertilizer industry, with testing facilities playing a critical role.As a key player in the development of the modern fertilizer industry, FEECO has been working with producers to develop custom fertilizer products – and the processes to support them – since 1951. .
You have many options when it comes to providing a healthy environment for plants.While numerous types of fertilizers can be an effective way to quickly amend soil to grow healthy plants, they contain synthetic chemicals.Compost, on the other hand, is an organic alternative to fertilizers, and you can make your own or buy it.Compost, sometimes called "black gold," consists of decomposed organic matter that enhances the soil with nutrients and microbes.If you make your own compost, the University of Missouri Extension says it is important to make sure that any plant remnants you add to the mix do not have soil-borne pathogens that might infest healthy plants.The biggest difference between fertilizer and compost is that while compost enhances the soil to create a beneficial environment for plants, fertilizer feeds plants. .
Fertilizer vs. Manure: Which to Use?
Both are also common additives for gardens to enrich soil and improve plant growth.About Fertilizer.When you purchase manufactured fertilizers, you will know precisely which nutrients the fertilizer provides and the amount of each nutrient the fertilizer offers.Adding fertilizer does not add any organic material to soil.Manure.The droppings of cows, sheep, poultry, and horses are the manure that is commonly used in the garden.Fertilizers don’t often contain manure, but manure can be used as a fertilizer.Beyond nitrogen, the nutrient content of manure is quite minimal in comparison with commercial fertilizers, depending on what the animals ate before producing the manure, and the age of the manure.Using Manure As Fertilizer.The main drawback of using organic matter fertilizers is that they are far less concentrated than synthetic fertilizers, which means less nutrients per pound of fertilizer.Manure should be worked into the soil instead of applying it directly to plants.Manure is not as rich as fertilizers in plant nutrients.Manure is organic material that is prepared by decomposition of crop residue or animal droppings, which is added to the soil to improve fertility.Fertilizer is any substance, organic or inorganic, that is added to the soil to increase the yield of crops.Manure applications increase the activity of microbial life within your soil, which improves soil quality tremendously.Adding manure increases the amount of organic matter in your soil.As fertilizer is often a chemical product, there are specialized instructions that should be used when adding it to your soil.Plants can be burned by manure that hasn’t been aged for at least six months due to the nitrogen, ammonia, and salts fresh manure contains.In compost, manure that includes bedding is a balanced green and brown ingredient.To use packaged commercial manure as a soil amendment, refer to the instructions to determine how much to use and what to mix it with.Lawn fertilizer has too much nitrogen for other plants, and the weed control chemicals in lawn fertilizer can be damaging to the plants in your garden.Amending the soil in your vegetable garden with manure adds nutrients and organic matter, making the soil better able to support healthy plants.It’s best not to use fresh manure, as fresh manure can burn your plants due to the high nitrogen and ammonia content, and it can also contain weed seeds if the manure is from an animal that consumes plants.Manure should be aged at least six months before you use it in an active garden.Chicken and cow manure are most commonly recommended for vegetable gardens, with chicken manure having the most beneficial nutrient profile for your plants.Can organic farmers use manure?Can you over fertilize plants?Too much manure can give your garden too much nitrogen and ammonia, resulting in plants being “burned.” Follow the instructions on commercially packaged manure for dosage, or follow the guidelines below, worked into your soil to a depth of six to eight inches.The high nitrogen content of fresh chicken manure means it will “burn” plants it comes into contact with, especially tender young plants.Before putting chicken manure in your garden, you need to age it for at least six months, or use it in one of the following ways.First, you can add chicken manure to a compost pile, if you have one going, or just mix it with lawn clippings or dead leaves.Spread 50 pounds of chicken manure over 100 square feet of soil and till it or work it in to a depth of six to eight inches.It will age right in the ground and give your soil a nutrient boost so it’s ready for spring planting if you spread the chicken manure after fall harvest is complete.Chicken manure needs to be worked into the soil within 12 hours of being spread, or much of the nitrogen it contains will be lost to evaporation.If manure is fresh, you can use it as a soil amendment as long as your garden is dormant and you have three or four months before the planting season.If your manure has been aged for at least six months, you can use it as a side dressing, or like compost or any other soil amendment.Follow the package instructions, or use the amount listed below, depending on the type of fertilizer you have.How much chicken manure should I put in my garden?Per 100 square feet of soil you’re treating, spread: 20 pounds of chicken manure without litter, 30 pounds of chicken manure including bedding, or 70 pounds of composted chicken manure.If your manure is fresh instead of aged for at least six months, you should only use it in a dormant garden with three or four months until planting time.Spread 50 pounds of fresh chicken manure per 100 square feet of soil you wish to treat, and till or work it in as you would aged chicken manure.The amount of manure you should use depends on the type you have (which animal the manure comes from).Poultry manure in particular needs to be mixed within 12 hours of spreading on the soil, or you’ll lose a lot of the nitrogen to the air.Fresh manure can “burn” plants with its nitrogen and ammonia content, not to mention can contain pathogens such as salmonella, E. coli, and parasites that you don’t want near plants you’ll be working with or eating.While there is a range of variation in the pH level of chicken manures depending on age of the poultry, age of manure, diet of the birds, and more, most chicken manure has a pH that falls between 6.5 and 8.0.However, it’s best not to fertilize just before rainfall because the rain can wash the fertilizer into bodies of water and storm drain systems, where it can affect your community’s water supply by increasing water pollution.It’s best to get the benefits of fertilizing before it rains by watering the fertilizer in yourself, so the amount of water is more controlled and fertilizer running off into the water supply can be avoided.You can water the fertilizer in yourself after applying it to make sure it spreads down into your soil.Whether steer manure is better than chicken manure depends on whether you’re amending your soil for nutrition or texture.Poultry manure has more of the nutrients plants need to thrive than steer manure does.Steer manure also contains more salt than dairy cow manure, and too much salinity in your soil can lead to stunted plant growth or the inability to grow plants at all.You should fertilize your plants when you water them so the water will help the fertilizer soak into the soil.Should I water plants before fertilizing?However, if you use a granular or dry fertilizer, you don’t need to water plants before an application.Using manure in the garden has lots of advantages, which is why gardeners have been amending soil with manure for generations.The nitrogen in manure is also more stable than the nitrogen in commercial fertilizers, manure releases its nitrogen slowly into soil over time, better meeting the needs of your plants than nitrogen that isn’t gradually dispensed.Compost manure is farmyard manure that has been composted during its aging process.What fertilizer is high in nitrogen?The Old Farmer’s Almanac covers How to Apply

Compost vs. Fertilizers: What's the Difference?
Compost or fertilizer — which one is best for your garden?Once formed, compost works to feed the soil..Fertilizer is one of a large number of natural and synthetic materials, which can include manure,nitrogen, phosphorus and potassium compounds.Create a more nutrient-rich soil which enables plants and vegetables to feed themselves.Time is the main drawback of compost, if you are planning to make your own.How to Make Your Own Compost.If the arrangement is very dry, add some water while applying the garden waste.To do this, sprinkle some manure or soil on top of each — this will bring bacteria and fungi into the arrangement, which will get to work breaking down organic material.Leave for around three months, then uncover the mixture and remove the compost.Advantages of Using Fertilizer.One of the key benefits of a fertilizer is that it adds nutrients to the soil.The risks of the chemicals are heightened further if they work their way into nearby bodies of water.On the other side of the coin, compost is organic and also cheaper than fertilizer — even more so ifyou make your own. .
Comparisons of Manure, Compost, and Commercial Fertilizers
In addition to being composted, sewage sludge can be recycled for beneficial use by direct application to land as a fertilizer.Leaves, Brush and Yard Trimmings (Yard Waste)—typically consists of leaves, brush, and grass clippings common to urban areas.Source The Composting Council Research and Education Foundation (CCREF)Commercial Fertilizers Advantages • Precise amount of N, P, K • Available in a range of nutrient levels (especially when blended) to provide the producer what is needed for the crop • Uniform material for ease of transport and application • Known properties of the material with predictable effect on crops • Widely availableCommercial Fertilizers Disadvantages • Costs vary and change during the year, and are currently at record highs • Often have higher chance for nutrient runoff or leaching, because of high solubilityManures Advantages • Often free (except for transport/application) • Adds organic matter (OM) to the soil which improves structure, increases water holding capacity, increases CEC and reduces erosion • Provides both available and ‘slow-release’ N, P, K and micro-nutrients to cropsManures Disadvantages • Nutrients can be easily leached through the soil profile or volatilized if left on the surface • Nutrient content is highly variable • May introduce human pathogenic bacteria such as fecal coliform or E.coli • May introduce weed seeds • Weight and bulk of transporting and applying wet manures to fieldsHow is Manure Typically Handled?Montana NRCS State Office (406) 587-6813Online Manure Nutrient Calculator http://www.agry.purdue.edu/mmp/webcalc/nutAvail.aspCompost Advantages • Lower water content: greater total concentration of nutrients than manure on wet basis • Adds OM that releases nutrients slowly • High OM content improves soil structure, increases CEC and water holding capacity – Greater water holding capacity may decrease irrigation needs and reduce pumping costs • Beneficial microbes in compost increase nutrient cycling and can suppress soil and foliar pathogensAdvantages to Compost, Cont’d • Few to no pathogens & weed seeds due to the heat generated during decomposition • Drier than manures with a reduced volume of 50-75%, making it easier to transport and apply • Possible source of income for various markets and applications • Market examples: Compost can be used by home gardeners, mine reclamation sites, as seed starter and potting mixes for nurseries, as a soil amendment for landscaping.Compost Disadvantages • Making compost involves costly equipment, planning, monitoring and time to produce • Nutrient enriched leachate must be controlled to prevent runoff or ground water contamination • May require special permits depending on quantity produced and if selling compost • Will likely be more costly per lb of available nutrient than either fertilizer or manureMaking CompostTypical Total Nutrients in Fertilizer Fertilizer SourcesFrequently Used%N% P2O5% K2OAbbreviations Anhydrous AmmoniaAA82Ammonium nitrateAN34Urea-ammonium nitrateUAN28-32Monoammonium phosphateMAP11-1348-62Diammonium phosphateDAP18-2146-54Potassium chlorideKCl60UreaUR46(Modified from Havlin et al., 1999)Typical Total Nutrients for Manure National averages of nitrogen (N), phosphorus (P 0 ), and potassium (K O) values of manures based on a dry weight and a wet weight basis. .
Compost vs. Fertilizer, Explained
We will break down the commonalities and differences between the two soil additives, and we also discuss the advantages and disadvantages of each.Compost is basically a mixture of decaying natural substances, such as animals, vegetables, fruits, leaves, eggshells, coffee grounds and grasses.Other soil amendments include lime, manure, leaf mold, ground bark, fertilizers, materials to change water retention levels, clay, gypsum, and more.Organic fertilizers, like manure, compost, or bone meal, are derived strictly from plant and animal sources.Inorganic, or synthetic fertilizers are fast acting, but can burn and damage plants.All fertilizers are required by law to use the NPK ratio system to measure the levels of Nitrogen, Phosphorus, and Potassium (K on periodic chart) within them.Provides essential nutrients that every soil needs, including nitrogen, phosphorus, potassium, and magnesium.Fertilizers can be more expensive to use than compost, which is often made from food trash, leftover leaves, and kitchen scraps.The organic matter in compost sponges up nutrients within fertilizer and stores them until they are needed by plants.Compost also provides many nutrients that plants need in very small amounts, like boron.But instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants.Sometimes the amount of compost gardeners are directed to add to the soil is very general, fertilizer application rates are based on the needs of plants.Chemical fertilizer can also feed composting, but continual use may throw off your soil’s chemistry and discourage beneficial insects and microbes.Crushing the eggshells before adding them to the pile will help them break down into the compost more quickly.Stale or moldy bread can be torn into small pieces and added to your compost pile.Add about an inch of compost to the top of the surface of your potted plants’ soil twice a year for best results.Put the moldy food in the center of the pile on top of dry brown material (like sawdust, ashes, straw, or leaves).Cover the food with material like grass clippings, cornstalks, or shredded paper.Keep in mind that the bits of perlite in your potting soil won’t break down in the compost pile.If this happens, you can pull them like weeds or transplant the tomato plants to the right part of your garden.Please note that if your tomatoes have contagious plant diseases, you should only add them to a hot compost pile.Although it’s possible to get too much compost in your garden soil, resulting in an overload of certain nutrients that’s bad for plants, this doesn’t usually happen.The only exclusion is onions that have soaked up lots of fatty or meaty juices, which shouldn’t be used because they can attract pests to your compost pile.It also takes a good bit of moisture to start breaking down a whole raw onion, so mix these well into the center of your compost pile.The orange peels will add phosphorus, nitrogen, and potassium to the completed compost.It’s not a good idea to fill a raised bed or any are of your garden completely with compost.Composted manure may be used as a mulch for plants once it’s had time in the heap, bin, or pile to break down.Another option is to till manure into the soil long before spring planting, like in the fall or winter, so it has time to break down.In addition to breaking down quickly, they’re full of nutrients to add to your soil, such as calcium, magnesium, phosphates, potassium, sodium, and sulphur.If you want your banana peels to break down even quicker, you can cut them into small pieces.Plant materials you should not compost include seed-containing invasive weeds, branches, wood chunks, and anything overly soggy.The results of getting too much fertilizer include burned roots, yellowing leaves, “leggy” or spindly growth, lots of foliage but no fruiting, and increased risk of pests and disease.Most of the time, these are available through your local Extension office, which you can find by choosing your state from this map on the National Pesticide Information Center website.If you choose a location in full sun, you may need to moisten your compost heap occasionally.To avoid adding too much compost to your garden at a time, follow this rule of thumb.For new garden beds, add one or two inches of compost per foot of loosened soil.When your compost looks like fertile, dark soil instead of a bunch of rotting food scraps, it’s ready to use.Allowing a few months after your compost looks done for it to “cure” helps ensure it’s chemically stable.If you’re digging in an area to start a new garden bed, you can add one or two inches of compost per foot of loosened soil.If you choose plastic bags or trash cans, open them up periodically to give things a stir and check moisture levels.You won’t be able to recognize its ingredients, and if you use hot compost, it will stop heating even when it’s mixed.Allow it to rest and to cure for a few months after this point to make sure it’s chemically stable.You can speed up the composting process by limiting your pile to one cubic yard, turning the materials once a week, and keeping your ratio of carbon to nitrogen around 20 to one.Keeping the pile moist and shredding or chopping the materials you add to your compost also makes things decompose faster.Rain before this time can wash the fertilizer away before it has a chance to become part of your soil.To make sure you don’t give your plants too much or too little fertilizer, rely on the instructions provided by the manufacturer that should be printed on the package.A fertilizer is anything that provides the plants you grow with the nutrients they need to thrive, including compost.There’s no need for you to add worms to your compost area, though it won’t hurt to throw them in.The exception to this rule is vermicomposting, which uses lots of worms that you’ll need to manage and care for yourself.Granular fertilizers should be followed with plenty of water to prevent burning your plants.Unless your style is hot composting, you should also not include gardening debris or plant matter that has a contagious disease.Non-food items that you should not place into your compost pile include human or pet manure, branches and wood chunks, coal fire ash, sawdust from treated wood, tea or coffee bags (grounds or leaves are OK), invasive weeds that have gone to seed, lots of soggy material, plastic, metal, glass, glossy or coated paper, wood ashes, lime, stickers/labels on produce, BBQ charcoal, synthetic fertilizer, and anything too heavy to decompose, like heavy cardboard.For instructions specific to the type of fertilizer you’re using, check the packaging for guidelines from the manufacturer.BackYard Boss covers Compost Versus Fertilizer: Which Choice for the Best Plants?Cornell University covers Worms in Composting: Frequently Asked Questions.Small Footprint Family covers 10

Why are manures considered better than fertilizers class 11 biology
Manures Fertilizers Increase the water holding capacity of the soil.To overcome the decrease in the productivity of soil, manures and fertilizers are added to the soil.Manures are obtained from the decomposition of dead plants and animal wastes and have a small number of nutrients and a large quantity of organic matter.Fertilizers are chemical substances of synthetic origins that are supplied to the soils to increase their productivity and increase the crop yield.Advantages of Manures and Fertilizers:i) They add nutrients to the soil without affecting its fertility. .
