Fertilizers and Manure
Introduction to Fertilizers and Manure:
Crop plants regularly withdraw minerals from soil. Unless and until minerals are replenished at intervals, the plants will develop disorders in structure, growth, reproduction, functioning and suspectability to disease. Minerals replenishment is done through addition of manures and fertilizers. By adding the manures the fertility ability can be increased in soil.

Fertilizers:
Fertilizers are commercially produced chemical formulations that provide nutrients to crop plants for overcoming soil deficiency, enhancing their growth and yield. A complete fertilizer is the one which contains all the three critical elements or minerals. Critical minerals are the ones which become commonly deficient,
Depending up on the critical element present, fertilizers are four main types:
Nitrogenous fertilizers: contain nitrogen as the principal nutrient.
Phosphatic fertilizers: contain phosphorous as the principal nutrient.
Potassium fertilizers: contain potassium as the principal nutrient.
Complex fertilizers: contains two or more critical nutrients.
Functions/Advantages of fertilizers:
Fertilizers are nutrient specific, so these supply specific elements to the soil.
Fertilizers are compact, so they are easy to store and transport.
Fertilizers are readily absorbed by the plants because they are soluble in water.
Application of fertilizers:
It should be applied scientifically in terms of proper does and timing with pre and post application precaution for their complete utilization.
Fertilizers can be applied before sowing, during irrigation, or sprayed on standing crops.

Manure:
Manure is a partially decomposed organic matter derived from plant and animal wastes which are added to the soil to increase its fertility.
Functions of Manure:
Organic matter: Manure provides a lot of organic matter to the soil which increases water retention capacity in sandy soils and drainage as well as aeration in clayey soils.
Nutrients: Manure enriches the soil with nutrients.
Soil organisms: it provides food for soil organisms like soil friendly bacteria and earthworm.
Recycling: By using biological waste materials as manure, we recycle the wastes and protect our environment from chemicals.
Limitations of Manure:
Manure releases minerals only slowly.
Manure is quite bulky.
Manure cannot be stored beyond a period of 1-2 months.
