Effect of Different Factors on Ammonia Volatilization Losses in Soils

Effect of different factors on NH₃ voliltilization losses were studied under laboratory conditions. The losses of NH₃ increased with increasing ESP of soil at all the soil water regimes. Effect of water content on NH₃ voliltilization losses was found in the decreasing order: flooding>saturation>field capacity. At 9 and 25 ESP levels the NH₃ volatilization losses were higher upto 15d, whereas at higher levels losses continued upto 42d. Addition Of organic mailer and plilcement of urea at 10 cm depth decreased the losses over no addition of organic mailer and surface broadcasting, respectively
