Welcome to my channel... Aaj ke video main, DAP aur NPK main kya antar hai vho bataunga aur aap mujhe comments main bataye ki kaunsa fertilizer aap use karenge apne plants main

During the current crop season there has been an outcry from farmers in Rift Valley over fertiliser supply, availability, quality and type. Today, I will narrow my discussion to Diammonium Phosphate (DAP) and NPK and their impact on the soils and yields. Reports have indicated that majority of farmers in Rift Valley are fixated on using DAP despite the State’s insistence that they use NPK.

NPK vs DAP

The traditional fertiliser used in planting of maize and wheat in Rift Valley is DAP. It contains 18 per cent N and 46 per cent P2 O5. In the current season, DAP had not arrived in stores of National Cereals Board by the time farmers were planting. The extension officers were persuading farmers to use the available NPK (23:23:0) that contains 23 per cent N and 23 per cent P2 O5 arguing that it is better than the DAP because it does not increase soil acidity. The farmers objected arguing that they wanted to use the fertiliser they trusted — DAP. Actually, NP fertiliser is more concentrated in nitrogen but weaker in phosphate. Since the farmers have been using DAP over the years, it is unlikely that the soils require such a fertiliser. To clear the air, a simple test called phosphate fixation capacity can indicate whether the soil requires phosphorus fertilisation every season. The argument by extension officers that the NPK fertiliser is superior to DAP because the latter does not acidify soils is highly debatable.
