Potassium nitrate is a unique source of potassium, both in terms of crop growth and yield, or from its nutrient composition. And potassium nitrate has the desired chemical and physical properties, and good environmental quality. (Haifa, 2009).
For all types of crops, potassium nitrate is the preferred source of potassium. Potassium Nitrate Potassium nitrate can increase the yield and improve the quality of vegetables, field crops, flowers, fruits and nuts (Haifa, 2009).
Potassium nitrate is the ideal source of nitrogen and potassium for plants. Many products and formulations contain potassium nitrate to suit the specific needs and growth environment of the crop. (Haifa, 2009).
1. Potassium nitrate provides efficient nutrition for plants
Potassium nitrate consists of 100% of the plant's large number of elements. It consists of cationic potassium (K +) and anionic nitrate (NO3-), and the N-P2O5-K2O ratio is 13-0-46 (13% N is equivalent to 62% NO3-, 46% K2O equals 38 % Of K +, add up to 100% KNO3). Potassium nitrate is the only fertilizer that provides two large amounts of elements, Potassium Nitrate both of which are the highest in any plant.
Potassium nitrate has high absorption efficiency. The synergistic effect of K + and NO3- helps the roots of plants to absorb two ions. In addition, the affinity between negatively charged nitrates and positively charged potassium ions prevents the adsorption of potassium ions from the soil particles, Potassium Nitrate allowing the potassium ions to be absorbed by the plant.
Potassium nitrate can exist in the form of crystalline powder and granules and is therefore suitable for a variety of fertilization methods. Efficient fertilization methods such as irrigation and fertilization, foliar spraying, topdressing and slowing fertilization measures to ensure that the nutritional elements timely, appropriate, appropriate application.
Potassium nitrate crystalline powder is an ideal product for irrigation fertilization and foliar spraying.
Potassium nitrate granules are suitable for soil fertilization (topdressing).
Polymers - coated potassium nitrate particles as controlled release fertilizers provide long-term nutrient supply for the entire growing season.
Potassium nitrate is an excellent source of potassium. Potassium is the main cation in the plant and can neutralize a lot of negatively charged mineral anions and organic acids. Therefore, potassium in potassium nitrate is very important for the growth and development of plants and the normal function of tissues. Potassium (K +) plays a vital role in many of the cell metabolism, acting as a process in which osmotic regulators are involved in regulating plant water use.
Potassium nitrate provides crop available nitrogen. Nitrate nitrogen is the most easily absorbed form of plants.
2. Potassium nitrate makes plants more robust
Potassium nitrate is almost free of chloride. When the concentration of chloride in the soil solution increases, the plant absorbs chlorides rather than the necessary anions (especially nitrates) that are bound to hinder plant growth. Increased levels of chloride cause toxic reactions, which may also result in reduced production or even plant death. And potassium nitrate is almost free of harmful chlorides, and nitrate in potassium nitrate can counteract the harmful effects of chloride.
Potassium nitrate is not harmful to roots. Unlike ammonium, nitrate nitrogen in potassium nitrate does not damage plant roots when soil temperatures rise.
Potassium nitrate improves plant frost resistance. Potassium in potassium nitrate helps to thicken the cell wall, increase the concentration of intracellular electrolyte, Potassium Nitrate thereby increasing the ability of plant frost resistance.
Potassium nitrate enhances plant resistance to disease. Potassium in potassium nitrate eliminates the accumulation of short-chain carbohydrates and non-protein nitrogen, and they themselves are hotbeds of bacterial, fungal, nematode and virus invasions.
Potassium nitrate enhances drought tolerance. Potassium nitrate helps to establish and expand the root system in order to better absorb moisture in the soil.
3. Potassium nitrate to increase production
The sufficient supply of potassium contributes to the high yield and quality of the crop. Therefore, Potassium Nitrate the application of potash can get higher value products and bring a higher return on investment for growers.
Potassium in potassium nitrate has a positive effect on the following quality parameters:
Fruit size: fruit is increased and uniform.
Fruit appearance: better coloring; rarely appear skin color defects or damage caused by mechanical damage or disease damage traces.
Nutritional value: protein, oil, Potassium Nitrate vitamin C and other high content.
Sensory characteristics: improve the taste and flavor quality
Extended shelf life
Good industrial processing quality
4. Potassium nitrate to reduce salinity
Nitrate in potassium nitrate can reduce plant uptake of soil in soil or irrigated water. Similarly, potassium ions in potassium nitrate can reduce the toxic effects of sodium. Therefore, it is highly recommended to apply potassium nitrate to salt-sensitive crops and when the irrigation water quality is poor.
5. Potassium nitrate increases the water use efficiency of crops and saves water
Nitrate in Potassium Nitrate Improves Plant Water Use Efficiency. Plants that use nitrates are more likely to use water than plants with ammonium plants, with a utilization rate of almost 100%. This difference is more pronounced, especially when the concentration of potassium in the soil solution is small.
Potassium in potassium nitrate prevents water loss. Potassium is associated with the opening and closing of the pores, which minimizes the transpiration of the plant and reduces the water requirement. And sufficient potassium in the plant can increase the efficiency of soil water absorption.
Potassium nitrate prevents salt accumulation. Potassium Nitrate Potassium nitrate avoids additional irrigation in order to rinse off the salt in the soil.
Potassium nitrate to improve soil properties
Nitrate in potassium nitrate increases the pH of the root surface. Root absorption of nitrate after the release of hydroxide ions (OH-), and in the root region to form a slightly alkaline environment, thereby improving the acidic soil properties.
Potassium nitrate improves the effectiveness of phosphorus and trace elements. Potassium Nitrate Nitrates in potassium nitrate promote the formation of organic acids (carboxylic acids) and allow them to penetrate continuously into the growth medium. In turn, this also contributes to the release of phosphorus and trace elements from the soil particles into the soil solution.
7. Potassium nitrate is easy to handle and apply
Potassium nitrate has high solubility in water. Potassium nitrate can be completely and rapidly dissolved in water, ideal for irrigation fertilization and foliar spraying. The solubility of potassium nitrate in water increases with increasing water temperature.
Potassium nitrate has no moisture absorption. It can be stored in bags or bulk, not due to moisture caused by agglomeration or difficult to deal with the problem.
Potassium nitrate can be mixed with other fertilizers. Potassium Nitrate Does not occur due to water insoluble and plug the drip or nozzle, it can be used to produce non-various formulations of the tank deployment products.
Potassium nitrate is not volatile. Unlike ammonium, nitrates in potassium nitrate are nonvolatile, so they do not need to be burnt to the soil.
