What is sustainable agriculture?

Sustainable Agriculture is a method of growing crops in environmental protection, achievement of considerable profit and leadership to successful communities of farms. In practice, sustainable agriculture seeks to find ways to be agricultural lands by continuous crop manufacturers. Relying on resources that are not available on agricultural land, such as water, soil nutrients and a suitable amount of sunshine, is considered unsustainable because the farm cannot be self-oven.

Although the term sustainable agriculture dates from the 80s, in the far past, attempts to create the best methods of agricultural land have certainly appeared. In the US, for example, George Washington Carver's pioneering work in the 19th century led to better understand how crops such as cotton could exhaust nitrogen in the soil. Finally, the cultivation of cotton led to non -reserved soil because of this exhaustion. Instead of artificial adding nitrogen to the soil, Carver defended growing peanuts and sweet potatoes that wouldNaturally added nitrogen back to the soil. This principle of growing crops and alternating crops, which serves to improve soil, is a characteristic feature of sustainable agriculture.

Farm adhere to the principles of sustainable agriculture will follow the following general rules:

• Water is available directly on the ground, either through rainfall, irrigation from streams on the spot or well. Submersible pumps in the holes must run on sun or wind energy, unlike standard electricity that is not available in place and flows the environment of fossil fuels. Any irrigation system should be set to deal with the needs of the crop without being excess.

• Most pesticides are not used because these may have a persistent environmental impact and also on people who consume any products that are grown. Fertilizers with chemicalsThey do not use for the same reasons. Instead, cow fertilization and recycled waste for crops are recommended for fertilization of crops.

• planting of one kind of crop, monoculture, is not sustainable because it will lead to exhaustion and erosion of soil. Therefore, more crops should be set with regard to soil improvement.

• Any agricultural machines relying on fossil fuels are unsustainable because they exhaust natural resources. Recent studies on the conversion of fossil fuel vehicles for the use of vegetable oils can do this with a more feasible recommendation.

Sustainable agriculture also depends on profitability. Any farm needs money to continue operation. This factor causes a greater problem for those who try to apply sustainable agricultural methods in agriculture. Generally, production is transported from farms to suppliers to shops, which includes the use of fossil fuels. Exhaustion of fossil fuels is not sustainable and the tingleness of profits NelCalculate due to different fuel costs and work.

Small farms that are sold directly to consumers can strictly follow the above principles. However, most people who buy production on farms must still drive fuel -dependent vehicles to reach these farms. This problem creates difficulties in achieving real sustainability.

The principles of sustainable agriculture represent a step forward in making multiple agriculture in the country. At this point, however, very few farms can be defined. Some environmentalists have designed models for the development of towns or villages where farmers would live close to other inhabitants, reducing relying on fossil fuels. Others suggest building community roof gardens in already established cities to increase sustainability. Although these models are still primarily conceptual, they offer an interesting answer to the question of how to feed the growing population of the world without further exhaustion of our resources.
