1、 Seven advantages of potassium nitrate
1. Potassium nitrate provides efficient nutrients for plants
(1) Potassium nitrate is composed of cationic potassium (K +) and anionic nitrate (NO3 -). It is analyzed that the share of n-p2o5-k2o is 13.5-0-46 (13% n is equivalent to 62% NO3 -, 46% K2O is equivalent to 38% K +, adding up to 100% KNO3). Potassium nitrate is the only fertilizer that can supply two many elements, nitrogen and potassium, which are the highest in any plant.
(2) Potassium nitrate has high absorption power. The synergistic effect of K + and NO3 - assists the roots of plants to absorb both ions. In addition, the affinity between negatively charged nitrate and positively charged potassium ions prevents the adsorption of potassium ions by soil particles, prolonging the time when potassium ions can be absorbed by plants.
(3) Potassium nitrate can exist in the form of crystal powder and particles, so it is suitable for a variety of fertilization methods. High power fertilizer application methods such as irrigation, topdressing and slow control ensure the timely, appropriate and appropriate application of nutrient elements.
(4) Potassium nitrate is an excellent source of potassium. Potassium is the primary cation in plants, which can neutralize many negatively charged mineral anions and organic acids. Therefore, potassium in potassium nitrate is very important for plant growth and development and normal tissue growth. Potassium ion (K +) plays an important role in many cell innovations. It acts as a permeability regulator and participates in several processes of regulating plant water use.
(5) Potassium nitrate supplies available nitrogen to crops. Nitrate nitrogen is the simplest form absorbed by plants.
2. Potassium nitrate makes plants stronger
(1) Potassium nitrate contains almost no chloride. Agrobiology believes that when the chloride concentration in soil solution is added, plants absorb chloride rather than necessary anionic (especially nitrate) nutrients, which will inevitably hinder the growth of plants. The increase of chloride content constitutes a toxic reaction, which may also lead to the decline of output value and even plant death. Potassium nitrate contains almost no harmful chloride, and the nitrate in potassium nitrate can counteract the harmful effect of chloride.
(2) Potassium nitrate is harmless to roots. Different from ammonium, nitrate nitrogen in potassium nitrate will not damage plant roots when soil temperature increases.
(3) Potassium nitrate improves the frost resistance of plants. Potassium in potassium nitrate helps to thicken the cell wall, add intracellular electrolyte concentration, and then add the frost resistance of plants.
(4) Potassium nitrate enhances plant resistance to diseases. Experts in agricultural biology revealed that potassium in potassium nitrate eliminates the accumulation of short chain carbohydrates and non protein nitrogen, which are themselves a hotbed for bacterial, fungal, nematode and virus aggression.
(5) Potassium nitrate enhances drought tolerance. Potassium nitrate helps to establish and expand the root system in order to better absorb water in the soil.
3. Output value of potassium nitrate
An adequate supply of potassium contributes to high yield and good quality of crops. Therefore, applying potassium fertilizer can obtain higher value products and bring higher return on investment to growers.
4. Potassium nitrate reduces salinity
Nitrate in potassium nitrate can reduce the absorption of chlorine by plants in soil solution or irrigation water. Similarly, the potassium ion in potassium nitrate can reduce the toxic effect of sodium. Therefore, potassium nitrate is highly recommended for salt sensitive crops and when the quality of irrigation water is poor.
5. Potassium nitrate improves the water utilization rate of crops and saves water
(1) Nitrate in potassium nitrate improves the utilization of water by plants. The utilization rate of nitrate plants was higher than that of ammonium plants, and the utilization rate was almost 100%. Especially when the concentration of potassium in soil solution is small, this difference is more significant.
(2) Potassium in potassium nitrate prevents water loss. Potassium is related to the opening and closing of stomata, which can minimize the transpiration effect of plants and reduce the water demand. Moreover, abundant Potassium in plants can improve the absorption power of soil water.
(3) Potassium nitrate prevents salt accumulation. Potassium nitrate prevents additional irrigation to leach salt from the soil.
(4) Potassium nitrate is fully water-soluble and can be used in any drip irrigation and sprinkler irrigation facilities to greatly improve the utilization rate of water resources, achieve the integration of water and fertilizer, and reduce the labor force.
6. Improvement of soil properties by potassium nitrate
(1) The nitrate in potassium nitrate is added to the pH value of the root surface. After absorbing nitrate, roots will release hydroxyl ions (OH -) and form a slightly alkaline environment in the root area, and then improve the properties of acidic soil.
(2) Potassium nitrate improves the availability of phosphorus and trace elements. The nitrate in potassium nitrate promotes the composition of organic acids (carboxylic acids) and continuously immerses them into the growth medium. In turn, this also contributes to the release of phosphorus and trace elements in soil particles into soil solution.
7. Potassium nitrate is easy to treat and apply
(1) Potassium nitrate has high solubility in water. Potassium nitrate can be completely and rapidly dissolved in water. It is an ideal choice for irrigation fertilizer and foliar spraying. The solubility of potassium nitrate in water increases with the increase of water temperature.
(2) Potassium nitrate can be mixed with other fertilizers. It will not block the dripper or nozzle due to water insoluble substances, so it can be used to produce dispensing products with various formulas.
(3) Potassium nitrate is non-volatile. Unlike ammonium, nitrate in potassium nitrate is non-volatile, so it does not need to be buried in the soil during topdressing.
Potassium nitrate has been tested in shopping malls for many years, and its effect is stable, green and pollution-free, which is also the primary reason for a wide range of users to jointly select potassium nitrate fertilizer. Fertilizer is good. We'll talk about it. Let's introduce a high-quality and efficient potassium nitrate fertilizer.
