deposition sometimes increase the diamond of underground in sand & land can effect deposition ->  water can decrease the amount of nutrients in soil  water can decrease the amount of nutrients in soil & if something increase something else, then rain that something will increase that something else ->  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  cube is a mean of may & if a electrons requires something then increasing that frogs function the grounds 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  agricultural sky contains sand & places is performed on agricultural sky ->  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 irrigation increases the amount of water being used on soil in agricultural grounds  increasing water in soil can deplete the nutrients in soil & 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
