If sustainable and practical irrigation methods are not followed, what negative consequence can occur in and around the soils of agricultural land?
a) decreased nitrogen in the soil can occur as fertilizers are not often injected in the irrigation water.
b) increased salinization of the soil can occur when salts in the irrigation water are left behind after evaporation.

d) increased organic matter can occur as the water can promote the breakdown of remaining plants parts in and around the agricultural field.
