Sustainable agriculture• Sustainable agriculture is the study of
relationships between organisms and their environment.
Sustainability can be understood as an ecosystem approach to agriculture. Possible sources of nitrogen that would, in principle, be available indefinitely, include:
Recycling growing legume crops industrial production
genetically engineering
Farming and natural resources
In some areas, sufficient rainfall is available for crop growth, but many other areas require irrigation.
develop drought-resistant farming systems policy and management actions: improving water
providing incentives drought-tolerant crop reduced-volume irrigation systems
reduce water loss not planting at all
Water
Soil Soil erosion is fast becoming one of the worlds greatest problems.
Some Soil Management techniques— No-till farming Keyline design
Growing wind breaks to hold the soil Incorporating organic matter Stop using chemical fertilizers
Protecting soil from water runoff
Land As the global population increases and demand for food increases, there is
pressure on land resources Land can also be considered a finite resource on Earth
Energy for AgricultureIn industrial agriculture, energy is used in on-farm mechanization,
food processing, storage, and transportation processes.
Economics Socioeconomic aspects of sustainability are also partly understood. Given the finite supply of natural resources at any specific cost and location
Soil treatment Soil steaming can be used as an ecological alternative to chemicals for soil
sterilization. Community and farm composting of kitchen, yard, and farm organic waste can
provide This composting could potentially be a reliable source of energy.
