Farmer-led research reported by Practical Farmers of Iowa explored the effect of having sheep graze cover crops on vegetable cropland. In the first year of this trial, Maja and Carmen Black were interested to see if there was a difference in the weight gain of lambs that grazed cover crops compared to those that grazed pasture. They found no difference in the average daily gain of the lambs. In the second year of the trial, Maja and Carmen were interested to see if there was a difference in yield of the summer squash between the plots that were grazed and the plots left ungrazed. They found no difference in marketable yield, but ungrazed plots produced more cull fruits. The complete report on the research trial is available online.
