Soil compaction first affects physical properties, as compaction occurs when soil particles are pressed together, reducing pore space between them and increasing the soil bulk density (Lipiec & Hatano, 2003; Raper, 2005; Reintam, 2006; Reintam et al., 2009). Soil compaction also influences chemical and biological processes, such as decreasing organic carbon (C) and N mineralization, the concent...

Experiments were conducted to determine the effects of plant confinement, soil type, watering practices, stage of seed germination, inoculum level, and method of applying inoculum on stem nematode (Ditylenchus dipsaci) infection of alfalfa (Medicago sativa) seedlings grown in soil. Results indicated that (i) confining seedlings together with the nematodes in small vials offered no advantage ove...

Soil Sci. 82: 1–8. Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared...

The effect of sole application of inorganic fertilizers (NPK) (N:P:K:: 30:26:25 kg ha ) and combined application of farmyard manure (FYM) @ 4 Mg ha 1 and inorganic fertilizers (NPK + FYM) vis-a-vis nonapplication of fertilizers and manures (control) on changes in soil physical properties and plant growth characteristics of soybean (cv. JS 335) was studied in a deep Vertisol at the Indian Instit...

This study presents a combined application of an EM38DD for assessing soil apparent electrical conductivity (ECa) and a dual-sensor vertical penetrometer Veris-3000 for measuring soil electrical conductivity (ECveris) and soil resistance to penetration (PR). The measurements were made at a 6 ha field cropped with forage maize under no-tillage after sowing and located in Northwestern Spain. The ...
