Potash saltpeter, potassium nitrate, use most often for fertilizing of different plants. This complex nitrogen-potassium fertilizer satisfies the need of crops for potassium.
Scopes of potash saltpeter
Such fertilizer as potash saltpeter, makes positive impact on the soil having average and the increased level of content of compounds of phosphorus. Usually potash saltpeter is used during the spring period, at this time fertilizer is especially effective.
If to fertilize plants and the soil potash saltpeter in the fall, then winter and autumn precipitation will wash up the nitrate nitrogen which is contained in fertilizer in the base soil layers. It can cause two main unpleasant moments. First, underground waters will become soiled. Secondly, fertilizer will be inaccessible for plants.
Quite often potash saltpeter is used for fertilizing of cultures on which chloric potash fertilizers make negative impact. Experts recommend to use potassium nitrate for sheet fertilizing and in the system of fertigation. Extra root feed of frost-resistant winter wheat in the period of kolosheniye is also carried out by means of such fertilizer as potassium nitrate. Hothouse plants feed up such solution: fifty grams of potash saltpeter on ten liters of water.
Properties of potash saltpeter
Potash saltpeter is one of the strongest oxidizers. It can react with reducers and combustibles. Density of nitrate of potassium is 2, 109 grams on centimeter cubic. Boiling temperature of potash saltpeter is 400 degrees Celsius, and melting temperature of 334 degrees. Potash saltpeter is toxic substance. For this reason in industrial premises it is very important to watch the correct concentration of substance in air. If the person inhales fumes of nitrate, then on mucous membrane of his nose hypostases and ulcers can be formed. The long contact of human body and potash saltpeter can promote emergence of thickening on skin of palms and foot. Such chemical compound as potash saltpeter is dangerous, also the fact that it is capable to provoke self-ignition of combustibles. In this regard it is strictly forbidden to smoke or make fire closer, than in fifty meters from storing places of potash saltpeter. The potash saltpeter produced in house conditions is especially dangerous. In case of ignition of combustibles because of potash saltpeter, the fire is extinguished dry or chemical foam extinguishers, large amount of water, dry sand or asbestos cover. It is very important to meet all security measures and storage conditions of such fertilizer as potash saltpeter. Vesta cannot store potash saltpeter with combustibles or mineral acids at all.
