The application of liquid pig slurry (LPS) to pastures offers potential as a fertilizer but could have direct influence on soil CO2 emissions. This study evaluated carbon dioxide emissions after successive LPS applications soils under pasture cultivation. experiment was carried out ‘Tifton-85’ bermudagrass cultivated in red-yellow oxisol the municipality Lucas do Rio Verde-MT, Brazil. Two treat...

A modern classification of pastures in Karakalpak Ustyurt has been developed, which combines 7 pasture types (Anabasis salsa, Salsola arbusculiformis-Anabasis Artemisia terrae-albae-Anabasis Haloxylon ammodendron, Tamarix hispida-T. elongata, Kalidium caspicum, Halocnemum strobilaceum), 2 classes (pastures stratal plains on gray-brown soils and drainless depressions solonchaks) 42 varieties, a ...

Two, 8-week experiments, each using 30 lactating Holstein cows, were conducted to examine performance of animals offered combinations of total mixed ration (TMR) and high-quality pasture. Experiment 1 was initiated in mid October 2004 and Experiment 2 was initiated in late March 2005. Cows were assigned to either a 100% TMR diet (100:00, no access to pasture) or one of the following three formu...

BACKGROUND, AIM, AND SCOPE Recent assessments of water quality status have identified eutrophication as one of the major causes of water quality 'impairment' not only in the USA but also around the world. In most cases, eutrophication has accelerated by increased inputs of phosphorus due to intensification of crop and animal production systems since the early 1990 s. Despite substantial measure...

collection and reuse of wastewater and sewage in agriculture, natural resources and green environment is one way to conserve water resources and environmental. the aim of this study were to investigate the effects of wastewater sirjan golgohar industrial on the characteristics of cultivated soils in several species of pasture trees. this study was performed at the sirjan city which is located i...

The research purpose is a comprehensive assessment of the Middle part Don river sand massifs soil and hydrological conditions. objects are sandy on an area 527 thousand hectares. arenas water balance dynamics for period from November to March April October has been revealed. It established that atmospheric precipitation main source supply. basis systems flood filling clay soils form intra-soil ...

Although the Amazon Basin is well known for its diversity of flora and fauna, this report represents the first description of the microbial diversity in Amazonian soils involving a culture-independent approach. Among the 100 sequences of genes coding for small-subunit rRNA obtained by PCR amplification with universal small-subunit rRNA primers, 98 were bacterial and 2 were archaeal. No duplicat...

A research worker in soil chemistry accustomed to cbfidk$ions in England is soon conscious in New Zealand of many anomalies in the position that liming occupies in local farming practice. In the major%y of districts in Great Britain the periodical application of lime is an establish& practice, and when this practice is neglected the failure of crops or of pasture is quickly notciceable. Moreove...

Historically isolated wetland ecosystems may provide a phosphorus (P) storage sink for runoff from agricultural pastures. Four historically isolated wetlands were characterized on two cow-calf ranches in the Lake Okeechobee Basin, Florida, to (i) quantify P storage in ecosystem compartments (plant biomass, litter, and soil) of historically isolated wetlands and surrounding improved pasture upla...
