On-farm validation of Alfalfa N Credits to Corn


Fri, May 7th, 2010
Posted in Agriculture

There is, what I consider, a very interesting research plot in Fillmore County this year. Jeff Coulter, Extension corn agronomist, and Michael Russelle, USDA-ARS soil scientist are following up on 2009 research in five other locations with research of "On-Farm Validation of Alfalfa N Credits to Corn." They are addressing nitrogen credit for corn following alfalfa, which is one of the most common questions I receive every year. A related potash study by Craig Sheaffer, professor of forage management, and Dan Kaiser, Extension nutrient management specialist, is also of interest. I also find this interesting, because a potash rate study was the first plot I was involved with in Fillmore County.

Rotating alfalfa with corn is useful to: 1) reduce soil erosion, 2) enhance soil tilth and carbon storage, 3) reduce weed seedbanks, 4) disrupt the life cycles of disease and insect pests of corn, and 5) supply nitrogen (N) to the subsequent corn crop. University of Minnesota N-credit guidelines for corn following alfalfa are currently based on alfalfa stand density and are 150 lb N/acre for ≥ 4 alfalfa plants/sq ft, 100 lb N/acre for 2 to 3 plants/sq ft, and 40 lb N/acre for ≤ 1 plant/sq ft. Respective second year alfalfa N credits are 75, 50, and 0 lb N/acre.

To adjust N fertilizer rates for corn following alfalfa, subtract the appropriate alfalfa N credit from the N fertilizer rate you would apply to corn following corn. The cost savings are huge for farmers that accept these alfalfa N credits and reduce fertilizer input accordingly.

Minnesota-specific N-fertilizer guidelines for corn following corn and other crops are available at: www.extension.umn.edu/Corn/nitrogen.html.

Table 1. First-year CORN-silage and grain yields following alfalfa as affected by final-alfalfa-year spring potash rates. Data are averages over five Minnesota locations in 2009, and five N-fertilizer rates applied to corn. (NS = yields were not statistically different among K fertilizer rates.)

With the high cost of N fertilizers, improved corn genetics, higher yields, and tight economic returns, validation of the University's alfalfa N-credit guidelines is important to ensure grower success.

In spring 2008, with funding from the Minnesota Agriculture Fertilizer Research and Education Committee, o n - f arm experiments were established in third or fourth-year alfalfa fields at five locations from southeast to central Minnesota.
