The changes of soil structure and water stability of soil aggregates under different compost doses

Popis výsledku v původním jazyce

During the years 2013 - 2015 different application of grape marc compost on soil structure and water stability of soil aggregates in the vineyard were studied. The trial was carried out in Velké Bílovice vineyard in Czech Republic. Altitude of locality is about 200 m above sea level, the long-term annual sum of precipitations is 550 mm, the long-term average annual temperature is 9.5 °C. The soil is Chernozem on loess, loamy textured. Three variants were established: Variant 1 –control, no compost, Variant 2 - 30t of compost/ha, Variant 3 - 60t of compost/ha. The compost from pomace, poultry droppings, mown grass and straw was made in an aerobic fermentor EWA in an intensive and controlled process in an enclosed space. The compost was evenly applied and shallow ploughed (0 – 0, 15 m) into the soil every year after harvest. Soil structure was assessed by sieving dry soil through sieves with the mesh size of 0.25; 0.5; 2. 5;10 and 20 mm.The water stability of soil aggregates was assessed using the method of wet sieving. Experimental results were statistically processed by the multifactorial analysis of variance and then by Tukey’s tests of simple contrasts. It was found that the application of grape marc compost into the soil had a positive effect both on the soil structure and the water resistance of soil aggregates.
