Sponsored: +29.4 Bu./A. 5-Year Average Advantage of Sub-Irrigation

In an effort to determine if yields can be increased by controlling the water table level with a sub-irrigation system, Beck's Practical Farm Research (PFR)® team in Indiana has conducted a five-year study at their Indiana site. 

The sub-irrigation system consisted of 3 in. tile, placed 24 in. deep and spaced 15 ft. apart, following the contour of the field topography.

Over the five years of this study, sub-irrigation has provided an average yield advantage of 29.4 Bu./A. over non-irrigated.

In a year with record-breaking yields, Beck's PFR saw a 3.9 Bu./A. advantage over non-irrigated fields in 2014. On the opposite end of the spectrum, 2012 brought one of the worst droughts on record and this study resulted in an additional 59.1 Bu./A. with the sub-irrigation system.
