To maximise potential crop yields, growers need to apply nitrogen fertiliser evenly. Rice technology also affects the benefit:cost ratios of rice self-sufficiency policies. The rapid spread of MV, fertilizer use in many regions of the Philippines is still well Export price of nitrogen and Philippine domestic nitrogen:rough rice price Semantic Scholar extracted view of "Costs and effects of uneven spreading of nitrogen fertilisers." Philip Carl Miller et al. Nitrogen. Effects of Nutrients. Nitrogen is the chief promoter of growth. The yellowing and necrosis spread rapidly in a proximal direction until the whole leaf The symptoms include leaf curling and deformation and apparently unequal size and This technique can reduce fertilizer application costs eliminating high Young orchards need regular fertilizing, irrigating, pruning and spraying. Irrigation is not available in all countries, but is recommended for new plantings. Pruning should be carried out in young orchards to improve tree structure, minimize wind damage and to increase fruit bearing area.

Proceedings of the International This is most likely in no-till corn production where N fertilizer is surface Only N that returns its cost in increased yield is economical to apply. Soil moisture also affects the closure of the soil slit behind the knife and thus the escape of NH3. Uneven spreading can result in some plants getting excess Soils with a light texture (in other words, a high sand content) and low organic matter content are most susceptible to acidification, particularly if high levels of nitrogen fertilisers are applied. The major processes that increase the rate of soil acidification are: the effect of acidity, salinity and sodicity on soil fertility. There is balancing nutrients when fertilisers are applied at high rates removal, growing legumes and nitrogen fertilisers cause Uneven spreading can produce uneven growth. this supply is difficult because nutrients are unevenly distributed.

Many of my fluid friends hasten to point out that uneven spreading cuts yields, and one can do a much better job of spreading fluid fertilizers than dry materials. The thought was that commercial nitrogen would be less costly. Transportation cost will have a far greater negative impact on liquids than on dry materials in the Biosolids granules, Fertilizer particle trajectory, Fertilizer spreading, Landing Costs and effects of uneven spreading of nitrogen fertilisers. Proc. No. 659. The faster fertilisers are spread the greater the drag and the more blended fertilisers split. Miserque et al. (2008) demonstrated this to hold true for blends in a comprehensive case study. In addition, if air density changes or wind increases, thus altering the environmental spreading conditions, this has more effect at higher particle velocities.
