| Abstract:
The present concept of “sustainable” fruit growing involves some management technologies in the orchards so that a balance between the tree growth and the fruiting processes should be maintained besides the biomass preservation within the ecosystem. This paper deals with studies highlighting such aspects related to the utilization of some less polluting technologies for the soil management. More exactly, the effects on the soil biotic and chemical processes of some soil management systems, applied in a high density apple orchard over a long period of time (22 years), were studied. Knowing that the tree rooting system is spread not only along the row but also between tree rows, for the interpretation of the correlations, were distinctly regarded the variants with the same rooting system along the row but with a different management system between rows. The most numerous correlations between the soil indicators, mostly very significant, were found in the mulched variant along the row and tilled soil between rows and the least ones in the variant with tilled soil both along and between rows. | |
