Changes in soil penetration resistance during spring and winter barley growing by soil conservation technologies
Slovak University of Agriculture in Nitra, Slovak Republic
Keywords: conservation technologies; spring barley; winter barley; penetration resistance
Abstract
The field trials were set up with spring barley (variety Nitran) and winter barley (variety Gerlach) and different soil tillage systems (conventional A, reduced - B, minimum - C). It was determined that soil loosening was greater at the depth of 10 cm in the variants with medium deep ploughing than in variants with reduced and minimum tillage. Higher and more uniform values of penetration resistance were found in greater depths in the variant with medium deep ploughing. The values of penetration resistance in the variant with minimum tillage, with maize as a preceding crop and disc harrow as a tool, were greater over all depths than in the same variant but with sugar beet as a preceding crop. The overall analysis of gained results on penetration resistance indicates that soil tillage systems A and B provided better conditions for the growth and development of plants. Furthermore results gained in trials with winter barley variety Gerlach in 2006 show uniform values of penetration resistance over all observed depths and tillage systems. Results accomplished on penetration resistance in 2007 show small differences between tillage systems A and B, while values determined for the system C were higher approximately by 100% at the depth from 15 to 40 cm.
