Sustainable Agriculture

Topic of the Presentation is …

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

Methods

The Great Irish Famine (1845–1849) is a well-known example of the dangers of monoculture.

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.
