Soil is a biological ecosystem, on which every living organism and their growth depends. Fertility is the ability to grow healthy plants, providing them with the nutrition, water and oxygen they need. Several factors that have an impact on increased yields are: the natural structure of the soil, the presence of groundwater and the level of soil contamination. Of course, there are also artificial human factors that reduce the quality and yield of the soil. These include: agro-tehnical cultivations (plowing the land) pest control, use of inorganic fertilizers. Black soil is considered the best soil, its formation takes several hundred years, while the destruction- in just 2-4 years. That is, over time, humus leaks out, the soil structure becomes clogged, most microorganisms die, and the flow of water and oxygen are deteriorating. At the moment, gardening is moving towards REGENERATION. Because regenerative gardening actually helps reverse climate change by building healthy soil.
*How to improve soil fertility?
1. Promoting Biodiversity-diversity is resilience
2. Application of organic(fertilizers) biostimulants. The recovery process depends on the soil structure. For soils as peat and chernozem, regular application of organic fertilizers in addition to nitrogen, is most suitable. They contain microorganisms that can significantly increase soil fertility several times in a very short time. Humus is an organic component of the soil, which is the mail food of the plants. Fertility depends on the availability and guantity of this component. Rich soil contains from 8 to 12 % humus. Soil with a high content of nutrients has a dark color and is ideal.
3. pH of acidity– Soil acidity is a chemical characteristic that allows to assess the suitability of the agro-technical environment for growth and development of the selected crops. The pH value varies, but it is best to be around 7 or 7,5.
4. Fruit rotation and soil fertility. Crop rotation is a scientifically based crop rotation of the land plots. The change of species allows to reduce the influence of these negative factors- with proper crop change, the soil structure is preserved.
