Recessional agriculture : ウィキペディア英語版 | Recessional agriculture Recessional agriculture is a form of agricultural cultivation that takes place on a floodplain. Farmers practice recessional agriculture by successively planting in the flooded areas after the waters recede.〔http://www.usaid.gov/pubs/mdb/africa.html〕 Thus recessional agriculture serves as a rudimentary form of irrigation.〔http://books.google.com/books?id=zjAhZpgabN8C&pg=PA230#v=onepage&q&f=false〕 Soil type is an important consideration in recessional agriculture. One type of crop grown by this method is sorghum. Clay soils are especially suitable for recessional agriculture. ==References==
