Revitalizace zemědělských půd
Vavřina, Jan
From the beginning of agriculture, an important soil-forming factor begins to take shape, and that is man. Human activity changes soil properties in favor of only one soil function, and that is plant growth (production, yield). However, these changes reduce the variability of soil properties, which are subsequently degraded and thus further disrupt the entire agroecosystem. New procedures, principles and agrotechnical measures that help to revitalize the soil are gradually being implemented across the world. These changes in the way agricultural land is managed take advantage of mutual ecological interactions that help to fulfill basic soil functions and provide ecosystem services. In the practical part of the work, two soils with different degrees of revitalization were compared. These soils were compared in relative values to the control soil, which was little affected by agricultural activities. The results show that agricultural soils have a lower stability of soil aggregates, bulk density, ammonium form N content, and SOM content compared to the control soil. At the same time, however, a higher respiration rate was recorded, which was influenced by tillage by taking soil samples.
