Food production is determined by a variety of factors including land ownership and use; soil management; crop selection, breeding, and management; livestock breeding and management; and harvesting. [18] Crop production can be affected by changes in rainfall and temperatures. [57]
Planting cover crops that keep the soil anchored and covered in off-seasons so that the soil is not eroded by wind and rain. Crop rotations [18] for row crops alternate high-residue crops with lower-residue crops to increase the amount of plant material left on the surface of the soil during the year to protect the soil from erosion.
The goals could include issues such as biosecurity, food security, rural poverty reduction or increasing economic value through cash crop or improved food distribution or food processing. Agricultural policies take into consideration the primary ( production ), secondary (such as food processing , and distribution ) and tertiary processes (such ...
Crop genetic diversity is one method that is used to reduce the risks associated with monoculture crops, which can be susceptible to a changing climate. [138] This form of biodiversity causes crops to be more resilient, increasing food security and enhancing the productivity of the field on a long-term scale. [138]
Mekong Delta farmers cut insecticide spraying from five times per crop cycle to zero to one. [citation needed] The Plant Protection Center and the International Rice Research Institute (IRRI) have been encouraging farmers to grow flowers, okra, and beans on rice paddy banks, instead of stripping vegetation, as was typical. The plants attract ...
It is based on in-depth understanding of chemical ecology, agrobiodiversity, plant-plant and insect-plant interactions, and involves intercropping a cereal crop with a repellent intercrop such as Desmodium uncinatum (silverleaf) [4] (push), with an attractive trap plant such as Napier grass (pull) planted as a border crop around this intercrop ...
The agricultural policy of the United States is composed primarily of the periodically renewed federal U.S. farm bills.The Farm Bills have a rich history which initially sought to provide income and price support to US farmers and prevent them from adverse global as well as local supply and demand shocks.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance (i.e. no-till farming), maintenance of a permanent soil cover, and diversification of plant species.
