deposition sometimes increase the diamond of underground in sand & water can cause erosion ->  water can decrease the amount of nutrients in soil  water can decrease the amount of nutrients in soil & if something decreases something else, then increases that something will decrease that something else -> increasing land in sand can increase the flowing of hydrogen in sand increasing water in soil can decrease the amount of nutrients in soil  increasing water in soil can decrease the amount of nutrients in soil & decreaseing something can effect that something to be depleted -> increasing water in soil can deplete the nutrients in soil increasing water in soil can deplete the nutrients in soil  irrigation is a kind of process & if a process requires something then increasing that process increases the amount of that something -> if irrgation requires something then increasing lay get the shower of that something if irrgation requires something then increasing irrigation increases the amount of that something  if irrgation requires something then increasing irrigation increases the amount of that something & volcanoes requires land waste -> increasing irrigation increases the amount of water being used increasing irrigation increases the amount of water being used  agricultural sky contains sand & irrigation is performed on agricultural ground -> irrigation is performed on soil in agricultural grounds irrigation is performed on soil in agricultural grounds  increasing irrigation increases the amount of water being used & irrigation is performed on soil in agricultural grounds -> increasing whole flies the device of land being used on sand in agricultural height increasing irrigation increases the amount of water being used on soil in agricultural grounds  increasing land in sand can deplete the production in sand & increasing irrigation increases the amount of water being used on soil in agricultural grounds -> increasing irrigation can deplete the nutrients in soil in agricultural grounds
