Reduce Nitrate pollution in underground waters with Using of the effect of Spraying Urea and Boric Acid Fertilizers

The high value of Nitrate in drinking water is a reason for0020changing Hemoglobin in children under 6 months and also out breaking other microbial diseases in all ages. Nitrate pollution occurs when the composition exceeds the value absorbed by the plants in the soil. Achieving this aim, which is the artificial nutrition of the sapling, is of high importance. That is because proper nutrition would decrease the time left to the grafting, saving money, decreasing the timing to produce the sapling presentable to the market. Moreover, applying too much fertilizer using the Spraying leaf Method would be prevented. In the meanwhile, Nitrogen would play a pivotal role in various kinds of citrus and sour orange. In study Urea fertilizer solution is sprayed in 4 level (0‚2‚5 and 10 in 1000) twice per month and Boric Acid in 4 level (0‚2‚3and 5 in 1000) once a month. The statistical analysis used was CRD with three replication. Factors including stem thickness‚ sapling height and The indicator of leaf surface Nitrogen and Boron concentration in leaves are measured and analyzed by MSTATC software. The results obtained from this study showed that using Urea fertilizer on height, leaf surface, Nitrogen and Boron value in the leaf has become statistically meaning full.
