1.to grow crops both in forests as well as in field conditions
2.helps to sustain life on earth.
3.helps to promote and sustain all the five elements e.i. Air, soil,/Earth,water,Solar systems Cosmic Energy which helps to make and sustain life on earth.
IPM is a Total Crop Health Management system or Programme which include requirement of agroecosystem, restoration of damaged agroecosystem found below and above ground , damaged due to indiscriminate use of chemicals in crop production and protection programme,nutrient , water and natural resource, management ,promotion of methods related with natural farming .,habitat management and conservation of biocontrol agents,natural resources and promotion of methods related with promotion and enhancement of crop fertility,joint impact of different types of plant physiological requirements such as different types of abilities found in plants ,replacement or reducing the use of chemicals with different nonchemical inputs and inputs required for Organic,Integrated and Natural Farmings etc.
Agro ecosystems not only include crop ecosystem but also their neibouring ecosystems such as Social ,Environmental, natural ,forest,water ecosystems etc which are also interrelated with each others and contribute in crop production and protection system in natural way or with the help of humanbeings. The fertility of crops is enhanced by Humus which is a kind of chemical found near the roots of the plants is made through the decomposition of the crop residues with the help of certain Bacteria. Air is a sea of Nitrogen which contains 78.6% Nitrogen .Nitrogen received from Air and provided to the roots of the plants with the help of Bacteria called Nitrgen fixing Bacteria.
Organic Carbon also play an important role for the preparation of food for plants with the help of Carbon dioxide and water in presence of sunlight and Chlorophyle which helps to grow plants .
The process in which carbon atoms continually travel from Atmosphere to the Earth and then go back in to the atmosphere is called Carbon cycle which helps to grow plants or crops .
Soil is the natural medium for the cultivation of crops .Plants or crops receive the nutrition and Water
from soil . Thus Soil /Earth,Water,Agni or Carbon ,Solar system /Cosmic Energy and Air play important role to grow crops or in crop production and protection system as these elements keeps the agroecosystem active .Hence Analysis of Agroecosystem will help us to produce and protect the crops by way of integrating various methods for crop production and protection as per the requirements of Agroecosystem.
