What is a phosphate fertilizer?
phosphate fertilizer is a high phosphorus fertilizer. Most phosphate fertilizers come from phosphate rocks, minerals mined in large number of millions of tons from places around the world. This mineral provides one of the three main nutrients needed by all plants for intensive growth; The other two are nitrogen and potassium.
phosphate rock is most often mined in large open mines; Remarkable deposits are in Morocco, China, Florida and South America. This raw ore is sometimes used as a fertilizer without further processing, especially in acid soils, where it serves the double purpose of pH increase. The fertilizers of rock phosphates become less common, as the raw rock provides relatively little phosphorus for its weight and transport costs, which is more expensive than refined phosphate fertilizer.
The process by which the phosphate rock is converted into phosphate fertilizer includes sulfuric acid treatment; The result is called "super phosphate". This treatment of sulfuric acid attracts phosphaThose from raw ore and create a water soluble form. It is mixed with water and creates a number of similar fertilizers in a concentrated liquid form that is easily applied to fields and crops.
water soluble super phosphate fertilizer is sometimes packed and supplied in granular form to reduce transport costs. This type of phosphate fertilizer is then mixed with water for application. Phosphate fertilizers are sometimes combined with other primary fertilizers to create complete fertilizers. Potassium and ammonium phosphate phosphate is combined with potassium and ammonia.
complete fertilizers contain a number of all three primary nutrients of plants; They are also usually combined into a granular mixture and are packaged for transport. These fertiles are marked according to the relative percent of the number of three components in the mass mixture and these proportions will be marked on the label by a number of threenumbers separated by dashes. These figures apply to the amount of nitrogen, phosphorus and potassium and are generally represented by their individual chemical symbols N, P and K.
Complete fertilizer can be marked as a formula of 10-15-20 N-P-K. This means that the fertilizer has a weight of 10% nitrogen, 15% of the phosphorus and 20% of the potassium according to the weight. The rest of the product consists of other ingredients that may include other nutrients that are used in smaller quantities such as sulfur, iron, magnesium and more.
