The effect of soil conservation tillage on soil moisture dynamics under single cropping and crop rotation

Abstract

During 1993–1995 the effect of conventional tillage, reduced till, mulch till and no-till technology on soil moisture dynamics has been studied in field experiment on Haplic chernozems near Piešťany. The tillage treatments were evaluated under a single cropping of maize and spring barley – common peas – winter wheat crop rotation. Soil samples for gravimetric determination of moisture content were collected from six layers up to 0.8 m, three times per year (April–July). The soil moisture was highly significantly influenced in order of importance by date of sampling, year, growing crops, tillage treatments, soil layer and by interactions year × crops, year × date of sampling, crops × date of sampling, tillage × date of sampling, year × tillage, date of sampling × layer and significant influences by interactions, tillage × crops. The soil under conventional tillage had significantly higher moisture content than tested reduced till, mulch till and no-till treatments. The significant influence of maize stand on better soil humidity condition (16.35%) in comparison to crops grown in a crop rotation (in average 14.10%) has been ascertained.

Seed dormancy and soil seedbank of the invasive weed Chenopodium hybridum in north‐western China

“…Soil MC had a large effect on dormancy breaking in C. hybridum , which is consistent with reports that seed dormancy was not released by cold stratification unless seed MC reached a critical value (Khan & Karssen, ; O'Reilly & De, ). The response of seeds at different levels of soil MC to cold stratification may have important ecological and practical significance, as soil MC varies with soil depth (Qiu et al ., ), tillage (Kováč et al ., ) and irrigation management (Kang et al ., ).…”

The influence of different tillage practices on water content of soil and crop yield in vetch–winter wheat rotation compared to fallow–winter wheat rotation in a high altitude and cool climate

“…Gozubuyuk et al (2014) determined that the germination is increased under notillage conditions, which obtained better water content of soil. On the contrary, some researchers determined lower water content of soil under no-tillage conditions (Aikins and Afuakwa, 2012;Kováč et al, 2005).…”

Anti-erosion effectiveness of selected crops and the relation to leaf area index (LAI)

“…These losses depend on the intensity of water percolation into the soil which is significantly influenced by tillage treatments and also by the slope of the terrain, rainfall intensity, cropping system and soil surface cover by the plants (Matula 2003, Kováč et al 2005. Changes of soil covererage significantly affect soil quality (Foody 2002).…”
