(C) the long-term depletion of soil oxygen.
(D) the clogging of waterways by vegetation debris.

Accepted Answer

Hello everyone here we have a question asking which one of the falling options is not a known issue that occurs as a result of intensive irrigation. A soil salinization, Soil salinization happens because after irrigation the water irrigated to the soil is used by crops or evaporates directly from the wet soil. This leaves behind the salts that is contained in irrigated water and basically the soil is then filled with these salt. So soil salinization does happen as a result of intensive irrigation. Be aqua for depletion, pumping water out of the ground faster than it is replenished for irrigation purposes, results in decreasing aquifer furs. So B does happen as a result of intensive irrigation, sea land subsidence, land subsidence is a gradual settling or sudden sinking of the earth's surface. This happens when there is intensive irrigation, because large amounts of groundwater are removed from certain types of rock. So C does happen as a result of intensive irrigation increased fertility. As we talked about earlier, intensive irrigation causes salinization, which actually decreases the fertility, so it does not increase the fertility it decreases. So our answer here is the increased fertility. Thank you for watching. Bye.
