Agricultural grade potassium nitrate fertilizer contains 13.7% nitrate nitrogen and 46.3% K2O. Crystalline in form and white in color. Potassium nitrate is the basis of a whole line of plain and enriched potassium nitrate products, designed for optimal plant nutrition.
Potassium nitrate is a high-quality source of both potassium and nitrogen, two essential macronutrients (primary nutrients) for plants. Since the healthy growth of plants requires large amounts of nitrogen and potassium, these elements have to be applied to the soil regularly.
This fertilizer enables the plant to minimize its uptake of chloride, whenever it is present in the soil solution or in the irrigation water. It is great against chloride-sensitive crops.
Product Features and Composition:
Particle size: On 35US mesh (>0.5mm) – 4.5% typ. Through 120US mesh (<0.125mm) – 20%typ.
Potassium nitrate fertilizer contains 13.7% nitrate nitrogen and 46.3% K2O. Crystalline in form and white in color.
It provides essential nitrogen in the most efficient nitrate form and a chloride-free K2O.
This fertilizer is ideal for plants that are sensitive to Chloride and high salinity. KNO₃ is a dissolvable/soluble source of two essential plant nutrients. It’s generally utilized as a fertilizer for crops that need nitrate (NO₃-) nourishment and a source of potassium (K+) free from chloride (Cl⁻).
Production
Producers ordinarily make KNO₃ fertilizer, also referred to as nitrate of potash or NOP by responding to potassium chloride (KCl) with a nitrate source. Contingent upon the goals and accessible assets, the nitrate may originate from sodium nitrate, nitric corrosive or ammonium nitrate. The subsequent KNO3 is indistinguishable paying little heed to the assembling procedure. Potassium nitrate is regularly sold as a water-solvent, crystalline material basically proposed for dissolving and applying with water or in a prilled structure for soil application. Generally, this compound is known as saltpeter.
Agricultural use
Growers value fertilizing with KNO₃, especially in conditions where a highly soluble, chloride-free nutrient source is needed. In such soils, the entirety of the N is promptly accessible for plant take-up as nitrate, requiring no extra microbial activity and soil change. Cultivators of high-esteem vegetable and plantation crops at some point want to utilize a nitrate-based nutrient of nourishment with an end goal of supporting yield and quality. Potassium nitrate contains a generally high extent of K, with an N to K proportion of roughly one to three. Numerous yields have high K requests and can evacuate to such an extent or more K than N at reap.
Utilizations of KNO₃ to the soil are made before the developing season or as an enhancement during the developing season. A weakened arrangement is once in a while showered on plant foliage to invigorate physiological procedures or to defeat supplement insufficiencies. Foliar utilization of K during organic product advancement points of interest a few yields, since this development organizes regularly harmonizes with high K requests during the hour of declining root movement and supplement take-up. It’s additionally regularly utilized for nursery plant generation and hydroponic culture.
