The answer is, yes by decreasing the N-fertilizer required. However, the length of time before legumes become reliable contributor to forage production can be almost immediately to several years. This difference is due primarily to previous management practices. Producers who have closely followed soil test recommendations for several years can expect significant contribution from legumes in the spring following establishment. Those who have not closely adhered to soil testing recommendations can expect to see legume production increase once any soil nutrient deficiencies, including low soil pH have been corrected.
