WebThe results showed that: (1) F1 and F2 treatments had the highest mean weight diameter of soil aggregates and significantly increased the proportion of >2 000 μm aggregates and this was mainly related to the enrichment of Pyrenochaetopsis; (2) F1 and F2, F3 and F4 treatments all increased the proportion of 2 000-250 μm aggregates, while they ... WebJun 1, 2014 · In the State of Rio Grande do Sul, the municipality of Pelotas is responsible for 90 % of peach production due to its suitable climate and soil conditions. However, there is the need for new studies that aim at improved fruit quality and increased yield. The aim of this study was to evaluate the relationship that exists between soil physical properties … MWD (mm) = mean weight diameter Dry Aggregate Stability Method. A dry sieving rotary cylinder described by Chepil (1962) can be used in combination with a nested sieve design, as described by the following procedure by Metting and Rayburn (1983): 1.
