Influence of conservation tillage for spring wheat sowing on soil structure
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 2
Abstract
The research was carried out in 2012-2014 at the Agricultural Experimental and Didactic Department of Gorzyń, a branch of Brody, belonging to the Poznań University of Life Sciences, as part of a static experiment established in 2006. The influence of the type of cover crop: white mustard and mixture of yellow lupine as well as field pea along with the method of the soil tillage for sowing cover crop and repeated cultivation of spring wheat on soil structure were investigated. The research carried out showed that the most favorable effect on the soil value structure index was exerted by the ploughing of white mustard, followed by ploughing or direct sowing of spring wheat. Direct sowing of both white mustard and spring wheat increased the weighted average diameter of aggregates (MWDa) in soil layers 0-10 and 10-20 cm. White mustard cultivation in a cover crop contributed to an increase in the rate of soil lumping and a significant decrease in soil pulverising in both analyzed soil layers (0-10 and 10-20 cm).
