Fertilizers provide an ...

Fertilizers provide an effective way to replace valuable plant nutrients that are removed in crop and animal products. Fertilizers also have potential to harm other ecosystems or impact food safety. Soil and plant testing is the foundation of management practices appropriate for specific sites and farming systems. Food safety and environmental issues associated with nutrients are areas of policy focus and public debate.

 Nutrient releases from CRF may be affected by soil factors including temperature, moisture, concentration gradient (ψS), pH, microbial populations, and texture. Factors intrinsic to CRF( controlled-release fertiliser) that may affect nutrient release include nutrient composition, coating thickness, and CRF prill shape and diameter.

These factors affect crop yields both directly (the plant) and indirectly (e.g. via soil conditions and crop management) and should be considered in long-term. The amount of rainfall from September to October shows positive influence on cashew yield in both zones. Total food grain yield over India during Kharif (summer) season is directly affected by variations in the summer monsoon precipitation (June– September). An increase (decrease) in rainfall is generally associated with an increase (decrease) in food grain yield. Agriculture feeds and clothes the world. Although the long-term effects of climate change are still largely unknown, scientists can observe short-term effects of climate change on crops and animals. In addition, scientists can prognosticate about the changes that are likely to occur in agriculture if global climate change causes changes in temperatures and rainfall.1

One is the CNC ratio in the soil, another is the Bacteria, Fungus, and other living organism, (enlivened soil) to help break down the soil and give the plant the necessary nutrients to absorb.  The ability to supply essential plant nutrients and soil water in adequate amounts and proportions for plant growth and reproduction; and the absence of toxic substances which may inhibit plant growth. Physically good to support plants and contain just the right amount of water and air for proper root growth. The soil must supply these essentials every day in the life of the plant.
