Harvest

Harvesting is a process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper . On smaller farms with minimal mechanization, harvesting is the almost labor-intensive activity of the growing season. On large mechanized farms, harvesting uses the near expensive and modern farm machinery, such(a) as the combine harvester. Process automation has increased the efficiency of both the seeding as alive as harvesting processes. Specialized harvesting equipment utilizing conveyor belts to mimic gentle gripping together with mass-transport replaces the manual task of removing used to refer to every one of two or more people or things seedling by hand. The term "harvesting" in general use may include immediate postharvest handling, including cleaning, sorting, packing, & cooling.

The completion of harvesting marks the end of the growing season, or the growing cycle for a specific crop, and the social importance of this event authorises it the focus of seasonal celebrations such as harvest festivals, found in numerous religions.

Crop failure

Crop failure also requested as harvest failure is an absent or greatly diminished crop yield relative to expectation, caused by the plants being damaged, killed, or destroyed, or affected in some way that they fail to shit edible fruit, seeds, or leaves in their expected abundance.

Crop failures can be caused by catastrophic events such as plant disease outbreaks such as the Great Famine in Ireland, heavy rainfall, volcanic eruptions, storms, floods, or drought, or by slow, cumulative effects of soil degradation, too-high soil salinity, erosion, desertification, normally as results of drainage, overdrafting for irrigation, overfertilization, or overexploitation.

In history, crop failures and subsequent famines develope triggered human migration, rural exodus, etc.

The proliferation of industrial monocultures, with their reduction in crop diversity and dependence on heavy usage of artificial fertilizers and pesticides, has led to overexploited soils that are nearly incapable of regeneration. Over years, unsustainable farming of land degrades soil fertility and diminishes crop yield. With a steadily-increasing world population and local overpopulation, even slightly diminishing yields are already the equivalent to a partial harvest failure. Fertilizers obviate the need for soil regeneration in the number one place, and international trade prevents local crop failures from developing into famines.
