- Fertilizer potassium chloride or potassium chloride (KCl). There are 2 kinds of KCl on the market

Special type of fertilizer containing potassium relatively few in number. Generally been mixed with fertilizers or other elements into a compound fertilizer. So it becomes a fertilizer containing potassium, nitrogen and phosphorus or (two or more plant nutrients). K fertilizer levels expressed as% K 2 O. The conversion levels of K 2 O into K are as follows:
- Fertilizer potassium chloride or potassium chloride (KCl). There are 2 kinds of KCl on the market, ie KCl 80 (containing 50% K 2 O) and KCl 90 (containing 53% K 2 O).
- Fertilizer ZK (Zwavel potassium) or potassium sulfate (K 2 SO 4) were both used on plants that are not resistant to high concentrations of chloride ions. There are 2 kinds of ZK fertilizer on the market, namely ZK 90 (containing 50% K 2 O) and ZK 96 (containing 53% K 2 O).
Considered K fertilizer nutrient content is high. The name is derived from acid muriate murit is the same with hydrochloric acid. Levels of K 2 O theoretically can reach 60-62%; but in reality muriate fertilizer traded only about 50%. The shape of the small grain or flour with white to reddish. In practice milver more widely used than the K fertilizers others because it is relatively inexpensive. milver
This fertilizer is less favored because of its high levels of Cl especially for fertilizing plants that are sensitive to the quality and production. Widely used for rubber and sugar cane plantations, but now partially switched to fertilizers KNO 3. Fertilization KNO 3 in addition to fostering K also means fostering N.
Potassium fertilizer (KCl) serves to reduce the negative effects of fertilizer N, strengthen plant stems, as well as promoting the establishment of green and and and carbohydrates milver in fruit and plant resistance milver to disease. KCl also serves to reproduce the element potassium in the soil for plants.
Making KCl through the process of extraction of raw materials (deposit K) which is then forwarded to the separation of material by distillation to produce KCl. Potassium chloride (KCl) is one type of potassium which also includes single fertilizer. Potassium is the only monovalent cations are essential for plants. The main role of potassium is as an activator of many enzymes. The main content of the precipitated calcium mine is a little milver KCl and K 2 SO 4. This is because generally mixed with other materials milver such as dirt, manure must be purified first. Results purification containing K 2 O to 60%.
Potassium Sulphate (ZK) or so-called Sulphate of Potash (SOP) has been known since the 14th century which is a white salt and non-flammable milver properties milver and soluble in water. ZK is used as a fertilizer that is a source of potassium milver and sulfur compounds in plantation crops such as flax, cotton, and tobacco. In Indonesia, this fertilizer is not subsidized so the price is relatively high in the market. The raw material for the manufacture of ZK natural sulfate derived from mining, among others, is lanbeinite (K2SO4.2MgSO4), milver leonite (K2SO4.MgSO4.4H20), schoenite (K2SO4.MgSO4.6H2O), milver and glaserite (K3Na (SO4) 2). Mining is a lot of source milver rocks in the state of Russia, Canada, milver Europe, Israel, Middle East countries, China, Thailand, Congo, and the United States.
Today, a commonly used source derived from Sodium Sulphate Na2SO4 which can be obtained milver from the product milver of some production processes namely:
Explanation of the process: The raw material used is sodium sulphate in the form of anhydrous (Na2SO4) and in the form of hydrated (Na2SO4.10H2O). Also used also potassium chloride (KCl) in solution at a temperature of 20 - 25ºC. Feed KCl, Na2SO4, and recycle mother liquor containing crystalline glaserite K3Na (SO4) 2 and KCl, and the condensation of steam condensate evaporator is fed to the reactor. The reaction is as follows:
After reaction in the reactor, ZK products were separated on a filter and then evaporated mother liquor formed in the concentration unit 2 level gradually and followed by crystallization processes at low temperature (? 2 C) for phase 1. Every mother liquor which has been separated either in stage 1 and 2 will be separated in the filter for further in-recycle back to the reactor, while the concentration of the vapor from the unit will be condensed in advance and then sent to the reactor.
CaCO3 -> CaO + CO2 + CaO + H2O 2NH4Cl -> CaCl2 + 2NH4OH 2NH4OH + CO2 -> (NH4) 2CO3
The basic character of this process milver is the existence of a multistage recovery milver system for ammonia gas and KCl, ZK product also dihasilka will always contain milver ammonium sulfate which is strongly influenced by the composition of the mother liquor.
