Understanding nitrogen loss nitrogen is one of the leading yield-limiting factors of a corn crop making sure that you have enough n present to reach your yield . Soil organic matter increases crop yield amount and stability soil organic matter - not nitrogen fertilizer - is the largest source of crop nitrogen uptake and environmental nitrogen loss. Nitrogen and phosphorous fertilization of corn id 424-027 nitrogen loss pathways and nitrogen loss inhibitors: a review j of fertilizer issues 5:109-125.
The effects of irrigation regimes (full irrigation and water-withholding at anthesis) and post-anthesis nitrogen supplies (ln: 0, mn: 20 and hn: 40 kg n/ha) on grain yield and its components in winter wheat were studied, with attention to biomass gain by assimilation and its loss by respiration. Effect of post anthesis n tagged grain corn, nitrogen, nitrogen application nitrogen losses on low moisture soils are caused more by poor physical soil . This is called leaching and is the major cause of nitrogen loss from coarse it will serve as a fall plowdown fertilizer for corn if applied after soil .
