The water-soluble NPK fertilizers are used for the complete restoration of the nitrogen and phosphorus in the soils. These products are capable of increasing the biological oxygen demand for all micro-organisms including plant roots and algae. They are useful for increasing the fertility and thereby the quality of the soils.
NPK is a method for the separation of nitrogenous and non-organic compounds from seawater. The main aim of these methods is to convert nitrogenous compounds to non-nitrogenous ones. The process of conversion uses bacteria called nitrobacteria. The major constituents of NPK are N-acetyl-l-cysteine, N-acetyl-l-glutamine, N-acetyl-d-glucosamine, and N-acetyl-sulfur compounds. In addition, some forms of N-acetyl-sulfur compounds are also used for increasing soil fertility.
The water-soluble NPK fertilizers offer the solutions for all types of problems that arise on agricultural lands. These products can be used for increasing productivity and therefore increasing the overall economic output of the farmers. The fertilizers improve yield by forming microorganisms in the soil. They improve the fertility of the soil which results in an increase in the quality of the crop sown. The water-soluble compounds in fertilizers facilitate the process of nitrogen fixation in the soil.
It is easy to use these fertilizers as they can be directly applied to the fields. Water-soluble NPK fertilizers do not contain any artificial additives and they do not contain any hazardous materials like VOCs (volatile organic compounds), ozone, or herbicides. These products are rich in nitrogen and they help in nitrogen fixation in the soil. Nitrogen fixation is the process of converting the nitrogen present in the soil into the form of usable compounds.
These water-soluble fertilizers are different from inorganic fertilizers in the sense that they do not provide the effect of chemical fertilization. They have a faster-acting effect on the soil. They also help in removing the surplus moisture in the soil and this results in balanced plant growth. Nitrogen-containing fertilizers should be applied before spraying the crop.
When using water-soluble NPK fertilizers, users are advised to ensure that the rate of application is consistent and then only it should be applied. The rate of application depends upon how fast the first traces of the fertilizer sink into the soil. If there is a delay between the time of application of fertilizers and the time of harvest, then there is a possibility that the nutrient content in the soil will decrease. It is better to apply the fertilizer in the early spring when the crop is still in its growing phase.
