chemical fertilizers (so -called black fertilizer and white fertilizer) are involved in supplying about 40 to 60% of the world's food sources. Chemical fertilizers include one or more food sources needed by plants that can exist in all three form of liquid solid or gas phases. These compounds can be added to both the soil, sprayed directly to the plant itself (plant leaves) or dissolve it in water and add to the soil. The use of these materials is used to improve soil quality, increase product levels or improve the quality of the product.
The use of these fertilizers dates back to the 19th century. When with the expansion of the agricultural industry, the amount of animal or plant fertilizers needed was restricted. The first attempts to produce industrial fertilizer from potassium from German mines began in ****, with about the same years that the first unit of phosphate fertilizer production of urea phosphate was also formed.
Nitrogen fertilizers or nitrogen or so -called white fertilizer (n)
White fertilizer contains nitrogen in the form of nitrogen, which is essential for the growth of many plants and therefore it can be used to help grow a wide range of plants. It has a very good dissolution capability and is easily dissolved in water and is quickly available to the plant.
Phosphate fertilizers or so -called black fertilizer (p)
After nitrogen fertilizers, this type of fertilizer is the most commonly used fertilizer in the world. These compounds are essential for proper growth of plant roots. They help increase crop yields and increase plant resistance to a variety of diseases. Black chemical fertilizer supplies the element of phosphorus for all kinds of plants, including pots, trees and crops.
Potass fertilizers (k)
is called fertilizer containing the potassium element of white fertilizer. Its types include potassium chloride (KCL), potassium nitrate fertilizer (KNO3) and potassium sulfate. This type of fertilizer also helps the overall growth of the plant, especially its roots, and increases its resistance to a variety of diseases.
Some potassium fertilizers:
Potassiops
Potassium sulfate
▪️ Potassium clutch
The amount of consumption and growth of the use of different fertilizers
Nitrogen fertilizers (white fertilizer) are still the most widely used in the world. But in recent years, the consumption of potassium and phosphate fertilizers (so -called black fertilizer) has also increased. The most important reasons for the increase in chemical fertilizer consumption over the years include population growth, alteration of food habits, change in agriculture that demands harvesting more crop per hectare.
refer to fertilizers that have the sum of the above elements in proportion to the so -called complete fertilizer (NPK fertilizer). Different plants will require the above fertilizers according to the need and according to the results of leaf and soil testing. The chemical composition and the purity of different fertilizers containing one element are very different. These differences have a significant impact on the consumption, how to distribute, fertilizer time and the effectiveness of fertilizers. Therefore, it is necessary to understand enough of the types of fertilizers before selecting or consuming them.
