The best combination of ammonium sulfate and urea nitrogen fertilizer formulated for use in pistachio what is chemistry orchards 1:12 am hour. Filed on 02/28/1391 Keywords:
The most widely used urea and ammonium sulfate as nitrogen fertilizers in pistachio orchards in Iran are considered. Typically used for fertilization what is chemistry of nitrogen or urea, or ammonium sulfate fertilizer, ammonium sulphate and urea synthesis in pistachio cultivation is used to supply nitrogen. Recent research has shown that ammonium sulphate and urea fertilizers should be used as both together. 46 percent of urea fertilizer and ammonium sulfate as the nitrogen in their composition and their composition is about 21% nitrogen. Each of these fertilizers have advantages and disadvantages. Urea in alkaline soils of the province can be severe and may cause further trouble Qlyayt soil and poisoning is the ammonium salt of the earth pistachio orchards earth alkaline conditions is the more appropriate great trouble of the ammonium sulfate enormous cost economic nearly half the amount of urea nitrogen is therefore not economically cost-effective. Economical and effective solution for nitrogen fertilization with urea, ammonium sulfate is combined with a specific ratio. The urea level is not high enough to be harmful to the soil as ammonium sulfate can be economically better off than taking action. Recent studies have found that the combination of urea and ammonium sulfate as sources of protein what is chemistry for nitrogen fertilizer added and mixed with ammonium sulfate, urea fertilizer efficiency what is chemistry and nitrogen (N) and considerably increases. NH3 gas is nitrogen in the soil and the soil composition of this compound is sometimes useful in many agricultural areas in the world, as artificial and NH3 gas in the soil or injects Targt. One problem with the rapid loss of urea in soil evaporation or NH3 gas emissions from soil during the height of the summer heat, it becomes more important. When ammonium sulfate with urea are used in both idiot or NH3 evaporation of soil fertility will be lower and that means more dust and dirt stay more NH3 In addition to the roots and the trees, can also be of minor and major soil being NH3 could use it would be very beneficial. In addition to the mixture of urea and ammonium sulfate can be very effective in reducing the amount of urea. Application of ammonium sulfate 2 to 4 weeks before the application of urea at pH 2/8 is reduced to half the amount of urea and NH3 volatilization from soils is due to a significant decrease (Kumar and Aggarwal 1988 (Goos and Cruz, 1999 .., as previously mentioned combining urea with ammonium sulfate can be very effective and can reduce what is chemistry soil evaporation rate of NH3 Many studies confirm this ((Lara-Cabezas et al., 1992, 1997; Vitti et al ., 2002. studies have shown that the amount of ammonium sulfate and urea in combination with higher rates of NH3 volatilization from soils will be less (Cantarella et al., 2003). research is very interesting about the combination of ammonium sulfate and urea The results were very interesting example is the combination of urea with ammonium sulfate, trace labeled nitrogen (N 15) found that in the presence of ammonium sulfate, urea, nitrogen uptake and increased 38% while the amount of N uptake 14 percent of urea decreased in the presence of ammonium sulfate (Watson, 1988). exact mechanism of the significant increase in the incorporation of ammonium sulfate and urea nitrogen is not completely clear. ammonium sulphate and urea at the rate of mixing or blending of different studies results are almost the same as the recommended 50% +50% of urea or ammonium sulfate, ammonium sulfate, 40% and 60% urea 65% urea and 35% ammonium sulfate (Vitti et al., 2002). ammonium sulfate incorporation another benefit Adding urea to form urea nitrogen only have to supply a significant amount of sulfur (S) in the ammonium sulfate fertilizer that can be spent on trees, while the urea is no element sulfur in its composition.
