The biochemical, microbiological activities in the replanted orchard - Katarzyna Sty¿a - Bog

Long-term cultivation of one species in the same site results in what is known as soil fatigue, which is conducive to the emergence of replant disease. In such conditions, the biological properties of soil deteriorate, which manifests in a decrease in the number of soil microorganisms. The reason may be the accumulation of allelopathic and phenolic compounds in the replanted environment, limiting the development of soil microflora. In Poland, there are more and more depleted plots in regions with intensive fruit growing. The situation is aggravated by the limited access to new positions, and therefore the threat of replant disease is becoming more severe. In this work was used biochemical and microbiological activities in apple-tree cultivation in the orchard after replantation as an important proxy for determining the biological activity and productivity of soils. Also, the book represents broad biochemical and microbiological parameters in the soils of an apple tree-orchard after replantation in different terms depending on the developmental phase and level fertilization.
