What is agriculture extensification?

What is agriculture extensification?

She has defined agricultural intensification as ‘the gradual change towards patterns of land use which make it possible to crop a given area of land more frequently than before.

What is the difference between agricultural intensification and extensification?

Intensification is defined as the increase in farm intensity, while the extensification describes the opposite trend. Farm input intensity is used as a proxy of agricultural intensification.

Is organic farming an extensification?

Organic agriculture is a case of extensification not allowing inputs like synthetic fertilizers and pesticides, nor allowing the use of genetically modified organisms (GMOs).

What is land extensification?

Extensification of farming is the opposite of intensification. It is the process of decreasing the use of capital and inputs (e.g. fertilisers, pesticides, machinery) relative to land area. Due to a decrease in inputs per land area the pressure on the environment may be decreased.

What is crop intensity?

It refers to raising of a number of crops from the same field during one agricultural year; it can be expressed through a formula. Cropping Intensity = Gross Cropped Area/Net Sown Area x 100.

Why is organic agriculture bad?

Other recent research has also concluded that organic farming produces more climate pollution than conventional practices when the additional land required is taken into account. The emissions impact of the meat, milk, and eggs produced from organically raised livestock is more complicated.

What is the largest agricultural crop in the USA?

Corn
Corn, soybeans, barley and oats The largest United States crop in terms of total production is corn, the majority of which is grown in a region known as the Corn Belt.

What is crop intensity index?

Crop intensity index assesses farmers actual land use in area and time relationship for each crop or group of crops compared to the total available land area and time, including land that is temporarily available for cultivation.

What is higher cropping intensity?

The cropping intensity is highest in small farms while lowest in large farms. Cropping intensity also differ in two stages of CRBC. Cropping intensity is high in Stage I due to canal irrigation (Paharpur Canal) and tube wells in the area.

What is crop rotation example?

With crop rotation, particular nutrients are replenished depending on the crops that are planted. For example, a simple rotation between a heavy nitrogen using plant (e.g., corn) and a nitrogen depositing plant (e.g., soybeans) can help maintain a healthy balance of nutrients in the soil.
