The analysis of the state destructive block in gray forest soils Novosibirsk region was carried out. Forest, meadow under pasture and vegetable agrocenosis were selected as objects study. Soil-zoological soil-microbiological methods used work. biomass soil microorganisms, basal respiration, metabolic coefficient, species richness total numbers oribatid mites studied. Strong changes studied para...

Grasslands in tropical environments are characterized by greater diversity than is found in temperate areas. In South Africa, greater diversity is found with the seasonally limited production which occurs on dystrophic soils under humid conditions in the sourveld, as opposed to the year round production that occurs on eutrophic soils under warm and drier conditions in the sweetveld. Most of the...

Dairy farm effluent (DFE) comprises animal feces, urine, and wash-down water collected at the milking shed. This is collected daily during the milking season and sprayed onto grazed dairy pastures. Urine patches in grazed pastures make a significant contribution to anthropogenic N(2)O emissions. The DFE could potentially mitigate N(2)O emissions by influencing the N(2)O to dinitrogen (N(2)) rat...

r a 200 .007 : +34 93 .edu (J.M Summary Submediterranean landscape around Vic includes, scattered over intensively farmed ground, a number of hills holding diverse mosaics of natural and seminatural communities. We chose two contrasting communities of pastures to investigate the soil water regime, assumed to be the cause of noticeable shifts in the landscape mosaics. Brachypodio-Aphyllanthetum ...

The compaction of soils used for crop production is becoming an increasingly important consideration in South Africa following the shift towards reduced tillage and increased mechanisation of in-season operations and harvesting. The intensification of dairying has also been found to have a deleterious effect on soil quality, particularly in terms of compaction by trampling, which results in los...

CTX-M [a major type of extended-spectrum beta-lactamase (ESBL)] producing Escherichia coli are increasingly involved in human infections worldwide. The aim of this study was to investigate potential reservoirs for such strains: soils, cattle, and farm environment. The prevalence of bla(CTX-M) genes was determined directly from soil DNA extracts obtained from 120 sites in Burgundy (France) using...

Drylands occupy 6.15 billion hectares (Bha) or 47.2% of the world's land area. Of this, 3.5 to 4.0 Bha (57%-65%) are either desertified or prone to desertification. Despite the low soil organic carbon (SOC) concentration, total SOC pool of soils of the drylands is 241 Pg (1 Pg = petagram = 10(15)g = 1 billion metric ton) or 15.5% of the world's total of 1550 Pg to 1-meter depth. Desertification...
