“…More enzyme activity in rice crop is also due to high moisture content in rice crop (flooding conditions in rice crop). Results are in agreement with the study conducted by Banerjee et al (2000) and Brzezinska et al (1998). According to them, soil water content and soil temperature influence soil dehydrogenase activity by affecting the soil oxidation-reduction status.…”

26The maintenance of soil quality is critical for ensuring the sustainability of the 27 environment and the biosphere. Although soil biochemical properties are considered 28 good indicators of changes in soil quality, few studies have been made of the changes in 29 biochemical properties brought about by anthropogenic disturbance of grassland 30 ecosystems. In the present study, several biochemical properties were analysed in 31 31 grassland soils subjected to a high level of management, and the values obtained were 32 compared with known values corresponding to native grasslands from the same region 33 (Galicia, NW Spain). The 31 managed grasslands were divided in two groups (re-sown 34 grasslands and improved grasslands) according to their management and past land use. 35The biochemical properties studied were: labile carbon, microbial biomass carbon, 36 microbial respiration, metabolic quotient, net nitrogen mineralization, and the activities 37

“…Long-term overgrazing has been shown to deteriorate soil physical and chemical properties in semiarid rangelands, contributing to decreased water retention, increased erosion, and enhanced soil nutrient depletion (Chen et al 2011;Teague et al 2011). Conversely, good grazing management practices in semiarid rangelands can create soil conditions with improved nutrient cycling and hydrological attributes (Thurow 1991;Banerjee et al 2000;Ingram et al 2008).…”

Grazing management effects on soil property dynamics are poorly understood. A study was conducted to assess effects of grazing management and season on soil property dynamics and greenhouse gas flux within semiarid rangeland. Grazing management treatments evaluated in the study included two permanent pastures differing in stocking rate (moderately and heavily grazed pastures) and a fertilized, heavily grazed crested wheatgrass (Agropyron desertorum [Fisch. ex. Link] Schult.) pasture near Mandan, North Dakota. Over a period of 3 yr, soil properties were measured in the spring, summer, and fall at 0-5 cm and 5-10 cm. Concurrent to soil-based measurements, fluxes of carbon dioxide, methane, and nitrous oxide were measured on 1-wk to 2-wk intervals and related to soil properties via stepwise regression. High stocking rate and fertilizer nitrogen (N) application within the crested wheatgrass pasture contributed to increased soil bulk density and extractable N, and decreased soil pH and microbial biomass compared to permanent pastures. Soil nitrate nitrogen tended to be greatest at peak aboveground biomass, whereas soil ammonium nitrogen was greatest in early spring. Drought conditions during the third year of the study contributed to nearly two-fold increases in extractable N under the crested wheatgrass pasture and the heavily grazed permanent pasture, but not the moderately grazed permanent pasture. Stepwise regression found select soil properties to be modestly related to soil-atmosphere greenhouse gas fluxes, with model r 2 ranging from 0.09 to 0.76. Electrical conductivity was included most frequently in stepwise regressions and, accordingly, may serve as a useful screening indicator for greenhouse gas ''hot spots'' in grazing land.
