Potassium nitrate is a great source of potassium because of its nutritional value and the contribution it has made to health of plants as well as yields. Potassium nitrate has desirable physical and chemical properties. It is also integrated with environmental qualities.
The fertilizer outshines other potassium fertilizers when it comes to fertilizing crops of all types.
One of the functions of potassium nitrate in plants it to promote and improves quality f field crops and vegetables, fruits and flowers and increases the yield of plants as well as nut trees.
It is a great source of nitrogen and potassium for perfect plant nutrition. Potassium nitrate exits in different formulations and compositions, to satisfy the requirements of a specific crop as well as grow environments.
Potassium nitrate for efficient plant nutrient
Consists of 100 percent macronutrients. It contains potassium cations and nitrate anions with N-P-O5-K2O analysis. It is the only fertilizer that has both macronutrients which is the highest in the composition of plants Potassium nitrate absorbers efficiently
The effect between the nitrate ions and the potassium ions stimulates the uptake of both ions by the roots of a plant. Also, the affinity between the positively charged potassium and the negatively charge nitrates stops the adsorption of potassium in the soil particles, making it exits in plants for a very long time.
Potassium nitrate is available in crystalline and prill form
This allows for various applications methods. Application methods such as foliar sprays, fertigation, controlled release fertilization and side dressing makes sure nutrients are applied in the perfect time, rates and placement. Crystalline potassium nitrate is ideal for application by foliar spray and fertigation. Prills of the fertilizer are ideal for side dressing. Prills of polymer coated potassium nitrate offers control production of nutrients throughout the growth season.
It is an excellent source of potassium
Potassium is the main cation in every plant. This positively charged ion balances negatively charged minerals, organic carboxylates and anions.
For this matter, the potassium nitrate fertilizer is important for the development of plants and normal working of the tissue. The potassium cation is also crucial in many metabolic processes inside the cells. It is also acts as an osmoregulator and is found in a number of processes that cater for water management in plants.
For stronger and healthier plants
Potassium nitrate is free of chloride
When the concentration of chloride in the solid is high, the plants absorb chloride on the account that it is an important anionic nutrient, particularly nitrate. This delays the growth of plants. When the concentration of chloride increases, this may cause more harm to the plant which may lead to reduce yield or even lack of yield because of plant death. Is totally free from chloride. The nitrate in potassium nitrate replaces the chloride compound and thus protects the plant form the effects of chloride.
Unlike other compounds such as ammonium, potassium nitrate fertilizer does not affect the roots of the plant. Potassium nitrate contains nitrogen and nitrate, these compounds ensures the roots of the plants are not affected or destroyed at high temperatures.
Improves plants tolerance towards frost
The potassium ion helps the cells to build a thicker wall. Thicker cell walls increase the concentration of electrolytes in the cells. This increases the ability of the plant to resist frost.
Helps plants to resist diseases
The potassium ion in the compound potassium nitrate gets rid of accumulation of non- protein nitrogen and short chained carbohydrates, which may act as substrates for preventing against viruses, fungi, bacteria and nematodes.
Helps plants to endure drought
Potassium nitrate promotes the growth of branches of a root system which can absorb water from the soil easily.
Potassium nitrate for great yields
When the supply of potassium nitrate is sufficient, it helps to get the best yields and also good quality. Hence using potassium nitrate fertilizer leads to a higher value product as well as descent return on investments for the farmer.
The potassium ions in the potassium nitrate have positively charged ions and they have a positive impact on quality parameters below:
It increases the size of the fruit, increases uniformity and increases the dimensions of the fruit. Potassium nitrate improves the appearance of the fruits. It also minimizes color blemishes and giver the fruit a better color. It also reduces the mechanical injuries on the plants as well as signs of diseases. The use of potassium nitrate fertilizer also increases the nutritional value of the plant, it leads to higher levels of protein, vitamin C and oil. Potassium nitrate has organoleptic characteristics and enhances aroma and enhances flavor too. It increases the shelf life.
Potassium nitrate combats salinity
The nitrate compound that is found in the potassium nitrate helps the plant to reduce chloride in take wherever this disastrous anion is in irrigation water or the soil solutions. At the same juncture, the potassium anions in the potassium nitrate reduce the harmful effects brought about by sodium. This is the reason potassium nitrate is highly used in salt sensitive crops and when using water that has poor quality.
Potassium nitrate saves water
The nitrate in potassium nitrate helps the plant control water management. Plants that have sufficient levels of nitrate can use water 100 percent more than plants that are fed with ammonium. This difference becomes more noticeable when the concentration of potassium in the soil is very low
The potassium ions in potassium nitrate help the plant reserve water. This is because it is responsible for the function of the stomata, which controls the opening and closing of its pores. The potassium ions reduces transpiration and minimizes its water requirements, also, sufficient amount of potassium nutrition enhances the water sourcing efficiency in the soil.
Potassium nitrate also prevents the buildup of salinity. Potassium nitrate also discards the need for irrigation to eliminate salt that is in the soil.
Potassium nitrate improves the properties of the soil
Potassium nitrate can dissolve in water
Potassium nitrate is highly soluble in water and it only takes a matter of seconds before it vanishes in water. This makes it an ideal compound for foliar application and fertigation. The solubility of potassium nitrate increases with increase in the temperature of water
Potassium nitrate is non- hygroscopic
You can store potassium nitrate either in bulk or in bags; it does not absorb moisture which may lead to caking and handling problems.
Potassium nitrate is works well with other fertilizers
Potassium nitrate is compatible with different types of fertilizers. It does not form insoluble precipitates that can clog nozzles or drippers. So you easily use it to make tank mixes as well fertilizer solutions of different compositions.
Potassium nitrate is not volatile
Unlike ammonium and other compounds, the nitrate cations in potassium nitrate are not volatile. Therefore, there is really no need to force it down into the soil when you are applying it bt side dressing or top dressing.
The Nitrate in potassium nitrate verses ammonium
There are three main sources of nitrogen that are used in agriculture. The first one is ammonium nitrate and the second one is urea. Oxidation of ammonia to nitrate is called nitrification. This process has three stages.
Advantages of nitrate fertilizer over ammonium containing fertilizers
Nitrate is not volatile at all, but ammonium is volatile. Therefore, you do not need to put it in the solid when you apply it by side dressing or by top dressing which makes it a great source of application. Nitrate is highly mobile in the soil, and it is directly absorbed by plants and thus has high efficiency.
Nitrate also stimulates the uptake of cations such as Mg, K and Ca while ammonium competes for these elements. If all nitrogen- nitrates are applied well, then there is no acidification of the soil. Nitrates are readily available for the plants to up take; furthermore, they can be absorbed in that state without being converted. The same applies to ammonium and urea before the plant absorbs it.
The conversion of nitrates to amino acids takes place in the leaf. The process is powered by energy from the sun which makes it energy efficient. Ammonium converted into organic nitrogen in the roots. This processed is powered by carbohydrates which may affect the growth of the plant and fruit fill.
It is quite evident that there is higher nitrogen uptake efficiency with the nitrate compound compared to ammonium.
