Why Are Organic Fertilizers Better
- October 31, 2021
Organic fertilizer is usually made from plant or animal waste – think manure or compost.>>For additional information on organic matter, read our blog: What is Humus?Organic fertilizer contains carbon as part of its chemical makeup; and it is the carbon, along with nitrogen, phosphorus and potassium that feeds microbes and enables them to make nutrients available for plants in a naturally occurring biological process.Synthetic fertilizers runoff into our waterways harming marine life and water quality.>>To learn more about fertilizer run off, check out this article: What Are Marine Dead Zones?Although organic fertilizer can be more costly than synthetic, it can reduce the need for pesticides and the overall nitrogen, phosphorus and potassium requirements.While you can produce your own compost, it’s a messy and complicated process that often leads to an inconsistent product and end-result.Bio 800⁺ products are plant probiotics filled with over 800 species of beneficial soil microbes that are microscopic fertilizer factories - converting nutrients that are unavailable, increasing the soil’s ability to hold onto nutrients longer and protecting the plant from stress caused by weather, disease and traffic.By utilizing a Holganix Bio 800⁺ product with reduced fertilizer and pesticides, you balance the need for a quick result seen with a chemical fertilizer and a safe, environmentally friendly result seen with an organic.Check out our top 10 favorite case studies from across the country by clicking the link below. .
5.3.1 Organic fertilizers.This is mainly because the organic matters in these manures stimulate heterotrophic bacteria, and, in turn, enhance the decomposition of organic matters in the pond (Diana et al., 1994; Diana, 2012).Nutrient contents in soil and water (particularly P and N), local climate, weather patterns and rainfall also influence pond conditions and productivity, and in turn, affect fish production from fertilization regimes (Diana, 2012).Green et al.

(1994) reported that only 6% of buffalo manure nitrogen was released as dissolved nitrogen and 35% of total P was released as soluble reactive P. Fertilization rate higher than 100 kg dry matter (DM) ha−1 per day caused water quality deterioration, high suspended solids and reduced light penetration and phytoplankton production.Generally speaking, a fertilizing rate of <100 kg ha−1 d−1 of poultry manure increases phytoplankton productivity and improves fish production (see Table 5.1).However, controversial results have been reported on the use of poultry manure for tilapia pond fertilization.These authors referred better tilapia growth and yields in pond fertilized with organic fertilizer (poultry manure), compared to inorganically fertilized ponds, to increased heterotrophic production and/or direct consumption of organic manure by the fish.Knud-Hansen et al.
(1993) found that the addition of urea and triple superphosphate (TSP) into Nile tilapia ponds increased N and P inputs in the ponds and improved primary productivity, while the addition of chicken manure to these inorganic fertilizers did not enhance fish yield. .
The Best Organic Fertilizers to Double Your Harvest
A neutral pH or one that’s slightly acidic for vegetables allows the highest availability to all plants.Sulphur is an essential macronutrient for plants and also can lower the pH in alkaline soils.Also watch for soil that is oversaturated or anaerobic: in these conditions the sulphur is converted to hydrogen sulphide, which kills developing roots. .
Inorganic Fertilizer Vs. Organic Fertilizer
Both organic and inorganic fertilizers provide plants with the nutrients needed to grow healthy and strong.Determining which is better for your plants depends largely on the needs of your plants and your preferences in terms of cost and environmental impact.Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorous and potassium.Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost.This slow-release method reduces the risk of nutrient leaching, but it takes time to supply nutrients to plants.Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. .
21+ Organic Fertilizers and How To Use Them In Your Garden
If your plants keep dropping leaves, turning odd colors, and generally failing to thrive, it might not be your gardening techniques that are at fault.However, it’s always a good idea to test the pH levels and the soil acidity in your garden before you start applying fertilizer.Adding unnecessary nutrients can also cause environmental problems since these compounds tend to get washed away in heavy rains and can end up polluting nearby waterways.Fertilizers were created to make up any soil deficiencies so that things can be grown in less than ideal spaces.Of course your plants don’t know the difference between synthetic and organic fertilizers but you will, particularly in the long run.They not only assist with water retention, they also make the soil lighter so that more air is available to the plant roots.These types of fertilizers even tend to be less likely to burn tender plant roots than synthetic products.The slow working nature of organic fertilizers is beneficial if you’re looking to improve your garden soil over time.(A good organic compromise when your plants need a sudden energy boost is liquid fertilizers or foliar sprays.).These types of fertilizers are generally added as a way of encouraging long-term growth in seedlings, transplants, and crops.They may additionally use a type of binding agent to help them be better absorbed by the plant in question.Liquid fertilizers are generally considered good for plants that are actively growing and should usually be applied on a monthly basis.While they aren’t fertilizers per se, these substances help plants absorb nutrients that they receive from elsewhere.However, paying for these elements to be included in your fertilizer can be a waste of money since healthy soil should already contain helpful substances such as microbes, enzymes, and humic acids.Read the instructions on the box and err on the side of caution when you’re deciding how much to apply.(Hint: it’s always a good idea to avoid using strong smelling products like fish emulsion fertilizer indoors.).Just be careful not to overdo it in order to avoid burning or even killing sensitive plants.The best use for this fertilizer is as a soil conditioner in the early spring prior to planting crops.The downsides to cottonseed meal are that it works slowly and that it is available primarily in cotton growing areas.However, this fertilizer is particularly useful for conditioning gardens in the fall before cover crops are planted or before mulch is applied.This gives the cotton seed meal time to break down fully so that the nitrogen present is readily available in the spring.Corn gluten meal contains trace amounts of nitrogen, phosphorous, and potassium.The main benefit of using rock phosphate is that the elements it contains don’t dissolve in water.However, some weed seeds may survive being digested by the cows in question and this can cause obvious problems.Having a lot of poultry crap on hand doesn’t mean that you’ll get comparatively high nutrient levels.Even so, this fertilizer contains slightly higher amounts of the three main plant nutrients than cow manure does.The best time to use poultry manure is just after harvesting your crops or just before you begin another gardening cycle.As is the case with cow manure, you’ll want to be careful with this product because it can burn your plants if too much is applied.As a result, this type of fertilizer is considered a great addition to flower and vegetable gardens.Compost’s nutrient profile varies based on what is put into but it is often close to that of cow manure.This characteristic negatively affects how well plants living in the soil can absorb nutrients.Improperly tended compost pile can additionally emit bad smells, which can quickly get city dwellers in trouble with their neighbors.Soybean meal is a high nitrogen fertilizer that also contains low amounts of phosphorus and calcium.Local growing conditions tend to affect how fast this product is absorbed into the soil but this process normally occurs at moderate rates of speed.Even so, blood meal’s fast-acting nature makes it a good tonic for ailing plants.You will need to pour this fertilizer over the plants roots according to the package directions and then possibly cover everything up with mulch.Bone meal works at moderate speeds to encourage flower production and root growth.However, bone meal is mostly used as a soil amendment for spots with high nitrogen levels where plants keep getting burned.If you plan on using this fertilizer in your yard, use it prior to planting in order to give the soil a nutrient boost.Seabird guano is gathered from islands that have low rainfall and arid climates, both factors which help it retain high levels of nutrients.Seabird guano contains large levels of trace elements along with decent amounts of nitrogen, phosphorus, and calcium.Bat guano is a fast-acting fertilizer that contains a wide variety of nutrients such as nitrogen, phosphorus, calcium, and various other minerals.Since some of the nutrients contained in bat guano are water-soluble, this fertilizer is probably at its most effective when used as a foliar spray or a compost tea.Fish emulsion nonetheless acts immediately once it is applied, which makes it a good treatment for leafy species that are suffering from low nitrogen levels.Shell meal also contains an element called chitin, which helps ward off pesky nematodes.Kelp contains small amounts of the main three fertilizer components but it’s quite high in trace elements.It is also a good source of growth hormones that can help plants reach their full potential.This liquid fertilizer is typically mixed with water and used as a foliar spray or poured into the soil around plants. .
Best Organic Fertilizers
Only since World War II has agriculture become dependent upon toxic synthetic fertilizers and pesticides.For some unknown reason, fertilizer recommendations continue to emphasize these three nutrients with special emphasis on high levels of nitrogen.Other studies show that an excess of chemical fertilizer slows or even stops the activity of microflora and microfauna, such as beneficial bacteria, algae, fungi, and other microorganisms.Harsh fertilizers also cause damage to macroorganisms, such as earthworms, millipedes, and centipedes, which are extremely important to the natural processes in the soil.Synthetic fertilizers glut the plants with nutrients immediately after application, which is usually at the wrong time.Here are my recommendations for the best, natural, organic fertilizers to boost your garden’s production and build soil health. .
Organic Foods: What You Need to Know
The term “organic” refers to the way agricultural products are grown and processed.Organic livestock raised for meat, eggs, and dairy products must be raised in living conditions accommodating their natural behaviors (such as the ability to graze on pasture) and fed organic feed and forage.Pests are controlled using natural methods (birds, insects, traps) and naturally-derived pesticides.Disease is prevented with natural methods such as clean housing, rotational grazing, and healthy diet.How your food is grown or raised can have a major impact on your mental and emotional health as well as the environment.Chemicals such as synthetic fungicides, herbicides, and insecticides are widely used in conventional agriculture and residues remain on (and in) the food we eat.Feeding livestock animal byproducts increases the risk of mad cow disease (BSE) and the use of antibiotics can create antibiotic-resistant strains of bacteria.Organically-raised animals tend to be given more space to move around and access to the outdoors, which help to keep them healthy.Results of a 2016 European study show that levels of certain nutrients, including omega-3 fatty acids, were up to 50 percent higher in organic meat and milk than in conventionally raised versions.Genetically Modified Organisms (GMOs) or genetically engineered (GE) foods are plants whose DNA has been altered in ways that cannot occur in nature or in traditional crossbreeding, most commonly in order to be resistant to pesticides or produce an insecticide.During large portions of the year it is usually possible to find food grown close to home at places such as a farmer’s market.Transportation: In the U.S., for example, the average distance a meal travels from the farm to the dinner plate is over 1,500 miles.Or the food is highly processed in factories using preservatives, irradiation, and other means to keep it stable for transport.In most cases, GMOs are engineered to make food crops resistant to herbicides and/or to produce an insecticide.For example, much of the sweet corn consumed in the U.S. is genetically engineered to be resistant to the herbicide Roundup and to produce its own insecticide, Bt Toxin.GMOs are also commonly found in U.S.
crops such as soybeans, alfalfa, squash, zucchini, papaya, and canola, and are present in many breakfast cereals and much of the processed food that we eat.If the ingredients on a package include corn syrup or soy lecithin, chances are it contains GMOs.While the U.S. Food and Drug Administration (FDA) and the biotech companies that engineer GMOs insist they are safe, many food safety advocates point out that no long term studies have ever been conducted to confirm the safety of GMO use, while some animal studies have indicated that consuming GMOs may cause internal organ damage, slowed brain growth, and thickening of the digestive tract.While many people think that altering the DNA of a plant or animal can increase the risk of cancer, the research has so far proven inconclusive.This chemical “body burden” as it is medically known could lead to health issues such as headaches, birth defects, and added strain on weakened immune systems.Children and fetuses are most vulnerable to pesticide exposure because their immune systems, bodies, and brains are still developing.Exposure at an early age may cause developmental delays, behavioral disorders, autism, immune system harm, and motor dysfunction.Pregnant women are more vulnerable due to the added stress pesticides put on their already taxed organs.The best approach: eat a varied diet, wash and scrub all produce thoroughly, and buy organic when possible.These practices can have health consequences for both the animals themselves and people consuming their meat, eggs, or milk.A natural foods co-op, or cooperative grocery store typically offers lower prices to members, who pay an annual fee to belong.Compare the price of organic items at the grocery store, the farmers’ market, online, and in other venues (even the freezer aisle).Making junk food sound healthy is a common marketing ploy in the food industry but organic baked goods, desserts, and snacks are usually still very high in sugar, salt, fat, or calories. .
Organic fertilizers are fertilizers that are naturally produced and contain carbon (C).Typical organic fertilizers include mineral sources, all animal waste including meat processing, manure, slurry, and guano, plant based fertilizers, such as compost, and biosolids. There are also other abiotic non-chemical, fertilizer methods that meet the Principles of Organic Agriculture, which determines whether a fertilizer can be used for commercial organic agriculture.Examples and sources [ edit ].Minerals [ edit ]. By raising the pH of a soil, microbial growth can be stimulated, which in turn increases biological processes, enabling nutrients to flow more freely through the soil.Animal Sources [ edit ].Animal sourced materials include both animal manures and residues from the slaughter of animals. By adding manure to crops it adds nitrogen, potassium, phosphorus, sulfur, magnesium and calcium. While also increasing soil stability by increasing organic material, increasing water infiltration, it can add bacteria diversity and over time reduce the impacts of soil erosion. However, there is organic manure and non-organic manure. There is also a risk of introducing weeds, as seeds can pass through the gut of an animal relatively unharmed, or there can be seeds in the bedding of the livestock, which is often mixed in with the manure.Urine, from humans as well as animals, is a fertilizer: urea in urine is a nitrogen compound, and urine also contains phosphorus and potassium.Compost bin for small-scale production of organic fertilizer.Plant [ edit ].Decomposing animal manure is an organic fertilizer source. .
8 Best Homemade Garden Fertilizers
Some of these fertilizers can be made or collected at home using common items from your pantry or your backyard.Just like grass clippings, many of the weeds that you’ll find in your gardens are very high in nitrogen and will make an excellent fertilizer.Then fill the bucket the rest of the way with water, and let the weeds soak for a week or two.Compost releases nutrients slowly, which means a well-composted garden can go a year or two without requiring reapplication of fertilizer.Compost also helps the soil retain moisture, which is essential for vegetable gardens to thrive during hot, dry summers.Leaves are rich with trace minerals, they attract earthworms, they retain moisture, and they’ll help make heavy soils lighter.Lots of plants, such as blueberries, rhododendron, roses, and tomatoes, thrive best in acidic soil.There are a couple of ways to do this— you can either top dress by sprinkling the used grounds over the surface of the soil, or you can make “coffee” to pour on your gardens.If you’ve ever used lime on your garden, then you know it comes with lots of benefits — chiefly, it helps lower the acidity of your soil for plants that don’t like acid, and it provides plants with lots of calcium, which is an essential nutrient.Lime itself is an all-natural fertilizer that you can buy at the garden center, but if you’d rather save some money, there is a cheaper way to get the same benefits.Simply bury peels in a hole alongside the rose bush so they can compost naturally. .
