Summary. This article is dedicated to the subject of designing additional tools for use with reversible ploughs that cuts and loosens topsoil. The aim reduce power consumption spent soil tillage by using roller cultivators. Methods. Theoretical experimental studies topsoil movement on plough’s wing, mouldboard beyond. Results. Analysis particles falling from top edge moulboard has allowed obtai...

Tillage erosion is a potential contributor to the total soil erosion occurring within cultivated fields. No study has been carried out on tillage erosion associated with cereal-based production systems, which are the predominant form of crop production in the Canadian Prairies. Previous tillage translocation studies have focused on primary tillage implements (i.e. mouldboard and chisel ploughs)...

Plough-breast is the crucial soil-engaging component of horizontally reversible plough (HRP). The unique merit HRP, in comparison to regular mouldboard ploughs, use remote cylinder (RC) drive its plough-body implement alternative shifting tillage operations. A major technical challenge operation violent soil-tool interaction, caused by varying RC speeds, appearing on plough-breast, particularly...

The effects of reduced tillage and lime on crop yield and soil physical and microbial properties were studied in a weakly-structured silty clay loam soil. Two autumn primary tillage practices were compared, mouldboard ploughing to 20–25 cm and cultivation to 12 cm. Seedbed preparation was carried out by several harrowing operations in the mouldboard ploughed treatment, and with a PTO-driven har...

a long-term rotation experiment was established in 2001 to compare conservation or reduced tillage systems (shallow rototiller and chisel tillage) with conventional tillage system using mouldboard plough in a semi-arid region with mediterranean climate. field experiments were conducted to determine weed density and profitability of cropping systems in a crop rotation of winter wheat (triticum a...

Amplicon length heterogeneity PCR (LH-PCR) was investigated for its ability to distinguish between microbial community patterns from the same soil type under different land management practices. Natural sagebrush and irrigated mouldboard-ploughed soils from Idaho were queried as to which hypervariable domains, or combinations of 16S rRNA gene domains, were the best molecular markers. Using stan...
