Dike It To Dam Costs

摘要

Furrow diking not only saves water - as has been proven by more than a decade of field research - but also slashes irrigation costs, says Russell Nuti of the USDA Agricultural Research Service. Nuti and team researcher Clint Truman, both with the ARSNational Peanut Research Laboratory, have been exploring the use of furrow diking in southeast states where water runoff is a problem. That team has looked at the effects of furrow diking on water needs and yields. Furrow diking is a tillage system wheresoils are scooped into ridge-like barriers running alongside row crops. The ridges hold irrigation and rainwater.
