Modified fallow management practices and modified sowing techniques were used to enhance wheat ( Triticum aestivum ) establishment in dry conditions. The effects of tillage, stubble management, deep sowing and press wheel pressure on wheat establishment were examined at various periods after...
This study evaluates the potential of no-tillage practices in the management of soils in semi-arid Mediterranean areas from central Spain. Field experiments on the interactive effects of tillage and crop rotations on soil chemical properties and crop parameters were conducted on a Calcic...
Field experiments during the 1992 and 1993 wet seasons examined in situ water conservation in rainfed lowland rice ( Oryza sativa L.) grown on a loamy sand by comparing subsoil compaction (C) with puddling (PUD), a plastic sheet barrier at 40 cm depth (PLS), and dry tillage (DT). Soil was...
Fractals are spatial and temporal model systems generated using iterative algorithms with simple scaling rules. This paper reviews the literature on spatial fractals as it applies to soil and tillage research. Applications of fractals in this area can be grouped into three broad categories: (i)...
Approximately one-half the soil in New Brunswick has naturally compacted subsoil and can benefit from deep-ripping. These soils are strongly acidic and pose chemical barriers to root proliferation even after deep-ripping. Therefore we determined the feasibility of placing large quantities of dry...
The soil nematode fauna was assessed as a potential ecological index for the progressive stages of degradation, as well as the possibilities of restoration of a Calcic Haploxeralf in a semi-arid environment in Spain. With this aim in mind, soil characteristics and nematode populations were...
