| Abstract:
As a rule, cultural practices can greatly alleviate the negative effects of “soil sickness”. The roots from the old trees did not affect the growth of young fruit trees. “Soil sickness” has also occurred when all roots in the soil were heaped up. The negative effects of replant were lessened when the management system in the cleared orchards was grass strips. Addition of compost to the planting hole positively affected the tree growth only if the grass strips were present in the old orchard. When the old orchard was managed as clean cultivation, compost application did not show a positive effect on tree growth. The grass strips greatly improved the rhizosphere microflora of seedlings in replanted soil as well as the response of VAM mycorrhizal fungus. | |
