abstract:
The research was conducted in experimental apple orchard on Haplic Luvisol developed from silt formation. The following methods of soil management systems in tree rows were compared: herbicide fallow treated with simazine (Azotop), herbicide fallow treated with glyphosate (Roundup 360SL), and mechanical fallow treated with hoeing. Morphological analysis of non-transparent soil blocks showed that soil structure in apple orchard under the herbicide fallows was favourable, similar to that of soil under mechanical fallow, or somewhat better. Content of water-stable aggregates of 0.25-10 mm inf diameter, especially of 1-10 mm and 1-5 mm, under herbicide fallows was similar to aggregate content under mechanical fallow, or even greater. The results showed that herbicide fallows treated with Azotop and Roundup did not cause any deterioration of the soil structure of Haplic Luvisol developed from silt.
