This study was carried out to investigate the impacts of bacterial inoculation on texturally different soil samples under greenhouse conditions. Sandy loam (SL), clay (CL), and (C) textured soils were inoculated with Bacillus arenosi K64 (B. arenosi), megaterium M3 megaterium), subtilis OSU 142 subtilis) isolates then incubated at 5 periods [I (20 days), II (40 III (60 IV (80 V (100 days)].

Soil compaction caused by machinery traffic in agriculture is a well recognised problem in many parts of the world as one of the most important factor responsible for soil physical degradation and has important consequences on crop production and environment (Soane and van Ouwerkerk, 1994; Keller and Arvidsson, 2004). It is estimated to be responsible for the degradation of an area of 68 millio...

background and objectives: kefiran (kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. the expansion of mixed systems can propose kefiran and polyvinyl alcohol (pvoh) as a new composite film. materials and methods: solutions of 20 gra...

Physical and chemical soil properties were measured along a mountainous climatological Ž . gradient in the province of Alicante Spain . The objective was to evaluate how the climate affects certain soil properties at different temporal and spatial scales. These properties include infiltration, runoff and sediment concentrations resulting from rainfall simulation experiments performed in winter ...
