Land use for animal production influences the earth system in a variety of ways, including local-scale modification to biodiversity, soils, and nutrient cycling; regional changes in albedo and hydrology; and global-scale changes in greenhouse gas and aerosol concentrations. Pasture is furthermore the single most extensive form of land cover, currently comprising about 22-26% of the earth's ice-...

We analyzed the effect of different tillage systems under land-use histories, on biological properties soil during one year. The experiment was carried out at a Petrocalcic Argiudoll Tres Arroyos (Buenos Aires, Argentina). specific aim to describe and compare organic carbon (SOC), basal respiration (BR) activities enzyme dehydrogenase, urease acid-phosphomonoesterase zero conventional soils pas...

Increasingly severe hydrological extremes are predicted for the Pannonian Basin as one of consequences climate change. The challenges extreme droughts require adaptation agriculture especially during intense growth phase crops. For dryland farming, selections optimal land use type and sustainable agricultural management potential tools facing posed by increased aridity. To this end, it is indis...

Hydrologic response varies within a watershed as a function of topography, soil, and land cover. Spatial and temporal data from experimental watersheds may provide information on where, when, how, and why the response varies. This study examined the hydrologic response of an agricultural watershed, FD-36, in the Appalachian Valley and Ridge physiographic region. FD-36 is characterized by shallo...

Inositol phosphates are the dominant class of organic phosphorus (P) compounds in most soils, but they are poorly understood because they are not easily identified in soil extracts. This study reports a relatively simple technique using solution 31P NMR spectroscopy and spectral deconvolution for the quantification of myo-inositol hexakisphosphate (phytic acid), the most abundant soil inositol ...

. The objective was to study the habitat complexity of mite populations on Caryocar brasiliense trees under natural and cultivated field conditions. performed in municipality Montes Claros, state Minas Gerais, Brazil, over 3 years. Three types areas were studied: 1) Cerrado, 2) pasture, 3) a university Campus. Several chlorotic spots detected leaves with larger Tetranychus sp. Eutetranychus (Te...

The potential dependence of virus populations on soil types was examined by electron microscopy, and the total abundance of virus particles in four soil types was similar to that previously observed in soil samples. The four soil types examined differed in the relative abundances of four morphological groups of viruses. Machair, a unique type of coastal soil in western Scotland and Ireland, dif...

Reforestation of riparian zones is increasingly practiced in many regions for purposes of biodiversity conservation, bank stabilisation, and improvement in water quality. This is in spite of the actual benefits of reforestation for recovering underlying soil properties and function remaining poorly understood. Here we compare remnant riparian rainforest, pasture and reforestation plantings aged...

Land use changes strongly impact soil functions, particularly microbial biomass diversity and activity. We hypothesized that the catabolic respiration response of the microbial biomass would differ depending on land use and that these differences would be consistent at the landscape scale. In the present study, we analyzed the catabolic response profile of the soil microbial biomass through sub...
