NPK is a compound fertilizer containing primary nutrients more than two types. With the nutrients n

[(CO (NH2) 2] Urea is the result of artificial fertilizer compound NH4 (ammonia) with CO2. Basic materials are usually in the form of natural gas and the mining of oil bonds. The content of total N ranged between 45-46%. In the manufacture of urea often formed biuret plexiglass compounds which are toxic to plants when present in large numbers. In order not to interfere with the levels of biuret in urea should be less than 1.5-2.0%. The content of N is high on Urea is needed at the beginning of plant growth. (Ruskandi, 1996 ).
SP 36 is a phosphate plexiglass fertilizers are derived plexiglass from phosphate plexiglass rock mined. Haranya element content in the form of P2O5 SP 36 is 46% lower than the TSP is 36%. In water when added with ammonium sulfate will raise phosphate uptake by plants. However, plexiglass shortcomings can result in the growth of the plants become stunted, slow ripening and lower crop production. (Judge, plexiglass et al, 1986).
NPK is a compound fertilizer containing primary nutrients more than two types. With the nutrients nitrogen content of 15% in the form of NH3, 15% of phosphorus in the form of P2O5, and 15% potassium in the form of K2O. Nature of nitrogen (nitrogen carrier) mainly in the form of ammonia will increase plexiglass the acidity of the soil to support plant growth. (Hardjowigeno, 1992).
Making KCl through the process of extraction of raw materials (deposit K) which is then forwarded to the separation plexiglass of material by distillation to produce KCl. Potassium chloride (KCl) is one type of potassium which also includes plexiglass single plexiglass 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 KCl and K2SO4. This is because generally mixed with other materials such as dirt, manure must be purified first. Purification results contain up to 60% K2O. 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 in fruit and plant resistance to disease.
Potassium nutrient deficiencies cause stunted plants, weak (not upright, nutrient transport plexiglass processes disrupted breathing and photosynthesis, which in turn reduces production. Excess potassium can cause the leaves rapidly aging as a result of leaf magnesium levels can be decreased. Sometimes being the lowest level so that the photosynthetic plexiglass activity disrupted .
The content of compost is organic material that reaches 18% even reached 59%. Another plexiglass element that is contained by the compost is nitrogen, phosphorus, calcium, potassium and magnesium. Benefits bokhasi on agricultural land that is: able to replace and make effective use of chemical fertilizers (inorganic) so that costs can be reduced fertilizer purchases, free of seeds of wild plants (weeds), odorless and easy to use and improve the acidity of the soil, but it is very useful to fertilize plant.
