Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the ...
Slash-and-burn is a type of shifting cultivation, an agricultural system in which farmers routinely move from one cultivable area to another. A rough estimate is that 250 million people worldwide use slash-and-burn.
Shifting cultivation is a type of subsistence farming where a plot of land is cultivated for a few years until the crop yield declines due to soil exhaustion and the effects of pests and weeds. Once crop yield has stagnated, the plot of land is deserted and the ground is cleared by slash and burn methods, allowing the land to replenish.

citation needed] While shifting agriculture's slash-and-burn technique may describe the method for opening new land, commonly the farmers in question have in existence at the same time smaller fields, sometimes merely gardens, near the homestead there they practice intensive "non-shifting" techniques.
Shifting cultivation (or slash and burn) is a system in which forests are burnt, releasing nutrients to support cultivation of annual and then perennial crops for a period of several years. [144] Then the plot is left fallow to regrow forest, and the farmer moves to a new plot, returning after many more years (10–20).
The HuffPost/Chronicle analysis found that subsidization rates tend to be highest at colleges where ticket sales and other revenue is the lowest — meaning that students who have the least interest in their college’s sports teams are often required to pay the most to support them.
The chitemene system, which creates a surplus of ash in concentrated spaces, raises the soil pH, enabling the cultivation of those crops. Furthermore, the heat generated by the burning of the biomass fumigates the soil, kills any existing weed seeds, and reduces the soil to a fine tilth, reducing labor requirements for cultivation of the soil.
