Discuss the biological nature of biofertilizers, highlighting their reliance on living microorganisms, in contrast to the chemical composition of traditional fertilizers. Consider their impact on soil health and sustainability.
Synthetic chemical fertilizer is focused mostly on Nitrogen Phosphorus and Potassium content. Nitrogen is mostly provided by the Haber Bosch chemical reation which gives Ammonia.
Ammoniated Fertilizer is the biggest fertilizer in overall use and consists well over half of all fertilizer application. On much area where ammoniated fertilizer is used the application has long term effect of acidifying the soil medium which can lower long term soil health. In addition the long term use ammoniated fertilzer can increase the soil nitrates which can lead to contaimination of water and aquatic ecosystems.
Excess nutrients from agricultural fertilizer can and does lead dead zones where the environmmt in marine areas become lacking in oxygen to favor fisheries.
When legumes are grown they can provide all their own nitrogen needs and sufficient Nitrogen for crops in rotations. In North America rotating maize with previous soybean eliminates the use of Nitrogen on the soybean crop and can provide a reductionof Nitrogen need on the maize crop.
When a wheat hay corn rye soybean rotation is employed the soil organic matter can increase without any Nitrogen application. This rotation is demonstrated with over 40 years of success compared to conventional chemical based system and the bottomline is that when the biological approach is used the increase of soil organic matter makes the products produced higher in nutiient and healthier.
The long term use of regenerative agricuture approach also improves the crop performance in drought years and under pests of disease and insects.
Symbiosis of the living soil employs the use of legumes but also results in improved network of mycorrhizal fungi which hold the soil surface and also improves the effective plant root systems critical of stable agriculture.
The combination of animals and plants are particularly regenerative and the manures and composts are highly effective as organic means of weaning from chemical dependencyl
The philosophy related to management precedes the changes found with are incrementabe and short in short term but huge over a longer term use.
Bio fertilizers are defined as containing living microorganisms and naturally derived substances. Bio fertilizers offer essential nutrients without polluting the soil with synthetic materials, but rather leads to the regeneration of soil and plant health.
1. Essential component of organic farming.
2. Preparation consists of efficient strains of Nitrogen fixing, phosphate solubilizing or cellulolytic microorganisms used for application to seed, soil or composting areas.
3. Play a significant role in improving soil fertility by fixing atmospheric nitrogen, with or without
Bio fertilizers are low-cost renewable sources of plant nutrients which supplement chemical fertilizers. Bio fertilizers generate plant nutrients like nitrogen and phosphorous through their activities in the soil or rhizosphere and make them available to the plants on the soil.
Both bio fertilizers and chemical fertilizers are used as a source of nutrients to improve plant yield and destroy plant pathogens. Chemical fertilizers are extracted and refined, whereas bio fertilizers are minimally processed. fertilizer is a man-made chemical compound whereas bio fertilizer is a natural substance. Fertilizers are typically made of inorganic compounds such as nitrogen, phosphorus, and potassium. Most fertilizers that are commonly used in agriculture contain the three basic plant nutrients: nitrogen, phosphorus, and potassium. Some fertilizers also contain certain "micronutrients," such as zinc and other metals, that are necessary for plant growth. With the increase in nitrogen fertilizers, the level of nitrate ions exceeds that in the natural nitrogen cycle whereby nitrate ions are returned to the air as atmospheric nitrogen. As a result, nitrate ions and other forms of nitrogen continue to accumulate in the environment and impose an environmental burden.
As rightly said already, biofertilizers are superior and proven strains of microbes which we introduce as plant/crop inoculants to revitalize the biological life within the soil so that farmers will have the power to restore their soil and therefore, is a holistic approach. While chemical fertilizers can increase crop yields, their overuse has made cop production areas into wastelands. On the other hand, biofertilizers restore the quality of the soil in addition to enhancing crop yields by 15-20% studies have shown.
