Answer:
Dry farming, also called Dryland Farming, the cultivation of crops without irrigation in regions of limited moisture, typically less than 20 inches (50 centimetres) of precipitation annually. ... Moisture control during crop growing consists largely of destruction of weeds and prevention of runoff.

Answer:
Erosion control techniques such as windbreaks, reduced tillage or no-till, spreading straw (or other mulch on particularly susceptible ground), and strip farming are used to minimize topsoil loss. Dryland farming is practiced in regions inherently marginal for non-irrigated agriculture.
