No-till notes - Irrigated no-till economics

No-till crop production has proven to be the best production system for conserving moisture. Leaving the previous crop’s residues on the soil surface and attached has improved water infiltration into the soil and reduced soil moisture evaporation.

Numerous research projects have shown the moisture conservation that no-till crop production provides under irrigation. The University of Nebraska has conducted research at the North Platte research farm which has shown that leaving residues on the soil surface reduces soil moisture evaporation up to 5 inches on bare soil and up to 3 inches of soil m...
