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.[2] 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 ].[7] 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.[12] By adding manure to crops it adds nitrogen, potassium, phosphorus, sulfur, magnesium and calcium.[10] 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.[10] However, there is organic manure and non-organic manure.[14] 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. .

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 response ratio in food grain crops in irrigated areas in India substantially declined between 1960 and 2008 (Biswas and Sharma, 2008).Efficient use of nutrient inputs on a farm is important for improving crop productivity and mitigating climate change.Enhancing nitrogen efficiency is directly responsible for nitrous oxide emission reduction and reducing agriculture’s contribution to climate change.Nutrient-use efficiency of nitrogen, phosphorus, potassium, and magnesium in all plant parts was significantly increased at elevated CO 2 (Seneweera, 2011).Regional nitrogen rates on cereals range from less than 10 kg N/ha in Africa to more than 150 kg N/ha in East Asia and, with the exception of Africa, partial factor of productivity of nitrogen continues to decline in all developing regions at rates of –1% to –2% per year (Dobermann and Cassman, 2005).Similarly, soluble fertilizers formulated with inhibitors reduce or block the conversion of nitrogen species by affecting specific types of microbes involved.The different nitrification inhibitors, such as dicyandiamide, nitrapyrin, and wax-coated CaC 2 in combination with urea were tested to quantify nitrous oxide emission in corn, rice, wheat, and barley crops.Among the nitrogen inhibitors, urea in combination with wax-coated CaC 2 reported low N 2 O emission over the urea-alone application (Mosier et al., 1994).Plant nutrient acquisition in an elevated CO 2 environment will be regulated by the interaction of compensatory adjustments in root growth, lifespan, physiology, and symbiotic association.The grain elemental composition of five wheat cultivars grown under elevated CO 2 showed a 2.5% decline in phosphorus concentration as against 15% for iron and 21% for zinc (Loladze, 2002). .

What is Fertilizer?When buying fertilizer, all of them will contain three big numbers, know as the NPK value.For example, a fertilizer with an NPK value of 20:5:10 means that the bag contains 20% nitrogen, 5% phosphorus, and 10% potassium by weight.The rest of the ingredients are usually inert (don’t have any effect); however, in some cases, additional nutrients are added in.All of the NPK nutrients are essential for plant growth.Nitrogen, for example, is naturally supplied to plants through microbial interactions in the soil, but not enough to feed our growing population.Should I Use a Synthetic or Organic Fertilizer?Inorganic or synthetic fertilizers are chemically manufactured supplements that contain growth-enhancing macronutrients.The key difference between the two is how quickly nutrients are available for your plant to use.Inorganic fertilizers have nutrients in forms that are immediately available, while organic fertilizers slowly release those nutrients to your plants.Organic Fertilizers vs.Fertilizers Containing Organic Compounds.This organic compound is used to deliver nitrogen quickly to plants, a red flag for being an inorganic fertilizer.NPK values are usually what inorganic fertilizers focus on, whereas organic fertilizers provide a balanced nutrient profile.The bioavailability of synthetic fertilizer macronutrients is high.Too much nitrogen will lead to nutrient lockout, and over time leaves will start to show scorched symptoms.Many of these organisms are responsible for converting organic nutrients into a form that your plants can use, with mutually beneficial relationships that promote healthy plants and soil.Most inorganic fertilizers don’t contain organic matter, which is needed for creating microbial products.This could lead to a loss of biodiversity and soil health.BlueSky Organics Fert-Alive™ is an organic fertilizer designed to give your plants the nutrients it needs. .

Plants need to be fertilized because most soil does not provide the essential nutrients required for optimum growth.By fertilizing your garden, you replenish lost nutrients and ensure that this year's plants have the food they need to flourish.If too much nitrogen is available, the plant may grow abundant foliage but not produce fruit or flowers.Phosphorus stimulates root growth, helps the plant set buds and flowers, improves vitality and increases seed size.Calcium is used by plants in cell membranes, at their growing points and to neutralize toxic materials.In addition, calcium improves soil structure and helps bind organic and inorganic particles together.Healthy soil that is high in organic matter usually contains adequate amounts of each of these micronutrients:.In general, the nutrients in organic fertilizers are not water-soluble and are released to the plants slowly over a period of months or even years.For this reason, organic fertilizers are best applied in the fall so the nutrients will be available in the spring.Soil microbes play an important role in converting organic fertilizers into soluble nutrients that can be absorbed by your plants.In most cases, organic fertilizers and compost will provide all the secondary and micronutrients your plants need.In fact applying too much synthetic fertilizer can "burn" foliage and damage your plants.For the long-term health of your garden, feeding your plants by building the soil with organic fertilizers and compost is best.This will give you soil that is rich in organic matter and teeming with microbial life.Plants can absorb nutrients eight to 20 times more efficiently through their leaf surfaces than through their roots.As a result, spraying foliage with liquid nutrients can produce remarkable yields. .

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. .
