How does polycoated urea respond in texturally divergent soils under different agro-climatic conditions?
We used to purchase pelletized fertilizer to provide more time release. Unsure if this polycoating is the same thing or for the same purpose. Moisture released the fertilizer in several storms, and we typically noticed a 5 year increase tree growth when using pelletized fertilizer. This also reduced volitization of fertilizer that may happen during hot or dry weather period if rain does not fall, but also reduced the release intensity of fertilizer so soils and plants could accumulate and use nutrients over a longer time period. Sandy soils may get the most benefit to time release as the nutrients are released over time, rather than a flush.
Thanks sir for your answer which satisfy me upto a satisfied level. But again in texturally divergent soils under different agro-climatic conditions performance of a particular fertilizer may vary. Secondly this polycoated urea (PCU) has 42% N against 46% N of the ordinary urea. We started our experiments and it is observed during wheat 2015-16 that 75% single split has almost similar performance as that of 100% in 3 splits. Hence our PCU saved 2 labour and 25% less urea in the sandy loam soils. Lets see what happened during the rice-season
