In times of high energy and
water costs, efficient irrigation is essential to the viability of many farms and
ranches.
In the next few
decades, more efficient irrigation may offer the best
hope of feeding the world’s
growing population.

Given the importance of irrigation efficiency, it’s unfortunate that irrigation water
management is often presented as a series
of complicated mathematical calculations
that only an engineer could love.
Irrigation
management is nothing more mysterious
than maintaining a suitable environment
for growing crops, mainly by keeping soils
from becoming too wet or too dry.
There
are many ways to achieve this goal, including some that require no calculations at all.
