Abstract

Questions often arise in June about "emergency or catch-up" fertilization for soybean. Most producers are not worried about this because they typically apply adequate amounts of phosphorus (P) and potassium (K) fertilizers before planting soybean or apply sufficiently large amounts before the previous year’s corn for both the corn and soybean crops. Producers asking questions wonder, however, if fertilizer rates were inadequate or if late planting dates, replanting and cold or excessively wet conditions have altered the crop nutrient uptake and fertilization need. Others wonder if the soil nutrient levels might limit high yield potential when growing conditions are good.
