Webform in the nodes of the plant. By V6, about 25-30 lbs of N/acre is taken up by the plants. Early sidedress applications can be made if the soil does not have sufficient N supply to meet crop needs. Recommended fertilizer rates will vary depending on soil N supply, soil type, drainage, crop rotation, yield potential and manure history. WebJustus von Liebig’s famous “Law of the Minimum” principle implies that crop yield is proportional to the amount of the most limiting essential nutrient, whichever nutrient that may be.
