Simulation models can be valuable to investigate potential effects of climate change on greenhouse gas emissions from terrestrial ecosystems. DNDC (the DeNitrificationDeComposition model) was tested against observed soil respiration data from adjacent pasture and arable fields in the Irish midlands. The arable field was converted from grassland approximately 50 years ago and managed since 2003 ...

ABSTRACT The objective of this study was to identify communities arbuscular mycorrhizal fungi (AMF) in soils under pasture, silvopasture, and Cerrado forest ecosystems, evaluate the effects land use system, soil texture, seasonality on dynamics AMF communities, Alta Floresta D'Oeste, Rondônia, Brazil. Samples 0-20 cm layer were randomly collected each ecosystem July, 2010 (dry season) January, ...

Abstract. Purpose. The study is aimed at carrying out an adaptation assessment of arid fodder shrubs for the restoration degraded pasture ecosystems in semi-desert zone southern Russia modern conditions climate aridization. Methods. An given adaptive capabilities, including field germination seeds, response to drought, yield leafless Calligonum aphyllum, Eurotia ceratoides, and Kochia prostrata...

This was assessed by determining NaHCO3–extractable inorganic and organic P in a range of temperate pasture Soil is commonly stored in an air-dried state for extended periods soils extracted immediately after air drying and followbefore chemical analysis. The effect of storage on P solubility was assessed ing air-dry storage for 3 yr at ambient laboratory temperaby determining NaHCO3–extractabl...
