Mineral fertilization.

We use mineral fertilization, as a complement to organic fertilization, and in its absence as complete fertilization. In the latter case, we use gardening mixtures, which also contain micron carts. To know, what doses of fertilizer should be used, You need to know the requirements of individual plants and orient yourself in soil abundance. So it's good to check the content of the nutrients from time to time, doing research at chemical and agricultural stations.

Soil mineral fertilization should be started with liming, which is aimed at:

- regulation of soil reaction by removing excess acidity,

- improvement of physical, chemical and biological properties of the Earth;

- Improving the nutrition of plants with calcium, but also other mineral ingredients;

- accelerating the distribution of green fertilizers and most organic fertilizers;

- Improving the development conditions of useful soil microorganisms.

Calcium occurs in fertilizers in the form of oxide or carbonate. Fertilizers containing calcium oxide work fast. Fertilizers containing calcium in the form of carbonate work slower.

The choice and dose of calcium fertilizer depend on the type of soil and its reaction, plant species and often on the costs of transporting fertilizer. Fertilizers containing calcium oxide are recommended for heavy soils, For light soils - calcium carbonate. Vaporic lime can only be used in autumn, and carbonate - and in autumn, and in the spring. Doses of calcium carbonate are 1-15 kg per 10 M2, and calcium oxide 0.6-1 kg. Revelation is unfavorable, because then non -exitable phosphorus compounds are formed, pipe, iron and manganese. Plants sensitive to freshly calculated soil belong: beans, pumpkin, carrot, parsley, harness, pea, cucumber and tomato and onion vegetables.

Wanting to determine the height of the lime dose, We must know the degree of acidification (pH) soil, which is easiest to determine with Polish acid meter. It can be purchased in garden stores together with the exact instructions for use. For most vegetable plants, the most appropriate soil reaction is pH 6.2-6.8. Weak soils, We limp sandy with small doses more often (1 KG na 10 M2); the pH should stay within the borders 6,3. We limit the stronger soils with higher doses (2 KG na 10 M2); The pH can be ok. 7,0.

We sown calcium fertilizers evenly over the entire surface of the plot or only on it. It's best to do this autumn. After sowing, the fertilizer should be mixed well with the soil when digging. We can plant or sow only after 2-3 weeks. If we limit the field in the same year, in which we eat manure, then we spread the lime first and mix them with the ground shallowly, Then spread the manure and dummy it. You have to remember, that it is not allowed to mix with lime ammonium nitrate and superphosphate.

Brown coal ashes are very good calcium fertilizer, also containing a lot of magnesium and a whole set of microelements. They can be purchased at power plants in Pątnów and Adamów and used in the same doses as carbonate lime. For the mineral fertilization of plots, we generally use gardening mixtures, convenient and protecting the soil against the lack of individual ingredients. Some of them must be supplemented with single -component fertilizers. Therefore, we should have a supply: ammonium nitrate, triple superphosphate and potassium sulfate. In the absence of the latter, we use potassium salt, But then we always loose it in autumn, giving slightly higher doses, Due to the possibility of flushing potassium by rainfall. The content of this ingredient in both fertilizers is similar.
