The task of fertilization is not only to nourish the plants, but also to stimulate soil life and promote the formation of humus, which we have already pointed out several times. Now we will give you some practical tips on fertilizing. The best fertilization results are obtained with the use of organic substances, that is, such, which until relatively recently were a component of living organisms. Organic fertilizers work differently than mineral fertilizers, the availability of which to plants depends on the water contained in the soil or from rainfall.
Animal waste substances (e.g.. horn meal) they stimulate soil life and contribute to the reproduction of soil organisms. Like a cultivated plant, which needs water and mineral salts from the soil for its growth and development, as well as air and heat from the environment, also mushrooms, bacteria and other soil organisms have very similar needs. Keep this in mind when using organic fertilizers. Organic substances used as fertilizers must first be crushed and processed in this way, to adapt them to the nutritional requirements of plants and the sorption capacity of the soil. Both plant development, as well as the activity of microorganisms depend on the same external conditions, which causes a close relationship between the process of formation and decomposition of organic matter. If the spring is damp and warm, both plants, and soil organisms develop rapidly. In cool weather, plant growth is inhibited, but then also soil-borne bacteria and fungi process less organic matter.
Already in the last century, Justus Liebig drew attention to the greater efficiency of organic fertilization, a Pfeiffer (1957) confirmed it and justified it. He stated, that the effect of organic fertilizers is twofold- and even three times more intense than mineral fertilizers. Based on many years of fruit experience by Furst (1967) confirmed the correctness of this view.
To better understand the role of organic fertilizers in natural farming and horticulture, we will divide them into four groups:
1) nawozy pochodzenia roślinnego,
2) odchody zwierzęce,
3) nawozy pochodzenia zwierzęcego,
4) mieszanki z wyżej wymienionych nawozów.
