We continue our fascinating conversation about the types of fertilizers.

Start here.

Mineral fertilizers contain more nutrients than organic ones. Mineral fertilizers are divided into two groups: complex and simple. Actually, simple fertilizers are those options that contain only one component. Complex nutrients can contain more than three nutrients.

In addition, all mineral fertilizers can be divided into groups also according to the content of various elements in them: potash, phosphorus and nitrogen variants are distinguished.

As for nitrogen mineral fertilizers, they will contain one of the most important nutrients - nitrogen in the simplest and most accessible form for plants. In this case, it is strongly recommended to adhere to a certain application rate of this fertilizer. Excessive nitrogen content in soil has the ability to adversely affect not only the health of humans, but also animals, and the entire state of the environment in general.

Ammonium nitrate, ammonium sulfate and urea should be distinguished among the most common options for such fertilization. Ammonium nitrate is often called ammonium nitrate, and carbamide is often called urea. Ammonium nitrate is a versatile fertilizer that quickly has a positive effect on plants. This fertilizer will acidify the soil. It is recommended to use urea in the spring, because plants will gradually absorb this fertilizer. Ammonium sulfate acidifies the soil very strongly, and also perfectly fixes in it.

Potash fertilizers are focused on helping plants absorb carbon dioxide. In addition, such feeding will increase the resistance of your plants to both frost and drought. Also, hydrocarbons will begin to move more actively.

The most common are potassium chloride, potassium sulfate and potassium salt. Potassium sulfate is also good because it contains neither magnesium, nor sodium, nor chlorine: after all, these elements can have quite impressive harm to plants.

Phosphate fertilizers will also help increase resistance to frost and drought. Phosphorus is inactive, so it is very important to apply such fertilizers as deep as possible into the soil itself.

Superphosphate is particularly effective. This fertilizer also has a quick action, and will also be well absorbed by the roots. To make the result even more effective, superphosphate should also be mixed with organic fertilizers.

Ash will not only alkalize the soil, but also saturate it with potassium and phosphorus. It is also good that the ash does not contain unwanted chlorine.

As for complex mineral fertilizers, they are sometimes also called complex fertilizers. This group should include karbofos, azophos, nitrophos, diammophos, nitroammophos, ammophos and potassium nitrate, as well as other fertilizers.

For perennial plants and bulbs, potash nitrate is ideal. Nitroammophos is used for annual plants, as well as perennials and bulbs. Ammophos will help prepare the soil for planting.

Most mineral fertilizers are fast-acting, so they have such an increased efficiency. You can determine the application rates of these fertilizers using the degree of soil fertility, a specific vegetable crop and the percentage of the main nutrient in the fertilizer itself.

Phosphate fertilizers are best applied in autumn, while other fertilizers are best applied in spring. On heavy and clayey soils, mineral fertilizers should be applied once before sowing. On light sandy soils, such fertilizers can be applied many times and in small portions: after all, such soil contributes to the fact that fertilizing can be washed away both during watering and after heavy rains.

Potatoes, beans, tomatoes and cucumbers do not tolerate the application of such fertilizers, which contain at least a small percentage of chlorine. Therefore, together with the potassium salt, you can choose potassium sulfate or ash, and ammonium chloride should be replaced with urea.
