Nitrogen is the most often deficient in soil and will be impacted by farmers associated with economic issue. exists systems many forms changes, such as mineralization mobilization, nitrification, denitrification, volatilization, runoff erosion, leaching. The Inceptisol has a pH of 5,5 (acid), impacting nutrients nitrogen, phosphor, potassium, organic-C; meanwhile, Ultisols have high acidity Al ...

The existing evidence for the nature of the phase diagram for the binary system sodium nitrate-potassium nitrate is reviewed and in particular whether the system is of the continuous solid solution type, as has often been stated in the last 80 years, or whether this system is of the eutectic type as was earlier believed and has again been asserted recently. Additional evidence from Raman spectr...

Potassium borates, which are widely used in welding and metal refining industry, as a lubricating oil additive, cement additive, fiberglass additive and insulation compound, are one of the important groups of borate minerals. In this study the production of a potassium borate mineral via hydrothermal method is aimed. The potassium source of potassium nitrate (KNO3) was used along with a sodium ...

Excessive chemical fertilizer application in greenhouse vegetable cultivation results environmental risks and residual nutrients the soil. Conventional plot experiments conducted one field cannot recommend reduction to farmers when nutrient levels were various among different fields. In this study, nine simultaneously fields where soils could reflect of nutrient, with two rates (100 0%) for eac...

nitrogen (n) affects adversely the tobacco yield quantity and quality as it increases yield, chlorine and nicotine contents, but decrease potassium content. this experiment was aimed at optimization of (the balance between) n concentration in leaf, stem and root to increase both yield quantity and quality (high potassium, low chlorine and medium nicotine contents) using artificial neural networ...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...
