The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. It includes all spatial and temporal aspects of managing an agricultural system.modern agriculture is increasingly concerned with promoting environmental sustainability in cropping systems.
Crop choice is the main aspect in crop system.Farmer must consider its profitability, adaptability to changing conditions, resistance to disease, and requirement for specific technologies during growth or harvesting.Managing crop residues is important in most systems. Some of the nutrients contained in these dead tissues are made available to crops during decomposition, reducing the need for fertiliser inputs.
Tillage is the primary method by which farmers manage crop residues.Leaving residues on the soil surface results in a mulching effect which helps control erosion,prevents excessive evaporation, and suppresses weeds. Burning are next step for crop In some systems residues are burned. This is a fast and cheap way to clear a field in preparation for the next planting, and can assist with pest control
Nutrients are depleted during crop growth, and must be renewed or replaced. A large component of the organic farming movement is a preference for organic-source fertilisers.Soil moisture content is an important factor in plant development. Irrigation and fine-textured amendments can be used to increase soil moisture
The most important factor of crop system is Removal of crop residues. crop residues may be removed and used for human or animal consumption, or other purposes. This provides a secondary source of sustenance or income, but precludes the benefits associated with leaving residues within the system.
