- Abstract:
- ... We investigated impacts of agricultural management practices on soil respiration (Rₛ) in a Cabernet Sauvignon (Vitis vinifera) vineyard (Oakville, CA; November 2003–December 2005). We determined (i) response of Rₛ to cover cropping, mowing and tillage; (ii) environmental factors controlling Rₛ; and (iii) total annual C lost through Rₛ A winter cover crop was either mown (CC+mow), or mown and tille ...

- Abstract:
- ... Agroforestry buffers, which include trees, grass, and shrubs, have been proposed for improving water quality in watersheds. The objectives of the study were to compare differences in macropore (>1000-μm diam.) and coarse mesopore (200–1000-μm diam.) parameters measured by computed tomography (CT) within agroforestry buffer (AgB) and grass buffer (GB) systems associated with rotationally grazed pas ...

- Abstract:
- ... The water-drop method (WDM) is a long-established and excellent means of measuring soil aggregate stability. While the WDM is very reliable, it has a drawback in that it requires manual observation of aggregate breakdown and a manual count of the number of water drops required to disperse a soil aggregate. This makes the method inconvenient and prone to error. To avoid this drawback, we propose a ...

- Abstract:
- ... The importance of riparian forests in maintaining water quality through the retention of sediments and nutrients is well understood; however, little is known about how sediment deposition from upland erosion affects the integrity of these systems. The objectives of this study were to compare decomposition rates, net N mineralization rates, microbial biomass, and other soil properties along a gradi ...

- Abstract:
- ... In Australia, the surface and subsurface soils of the majority of cotton (Gossypium hirsutum L.)-growing regions are sodic. Application of organic amendments can be an option to stabilize the structure of sodic Vertisols due to their potential positive effect on soil physical properties. An incubation experiment was conducted for 4 wk in a temperature-controlled (30°C) growth chamber to study the ...

- Abstract:
- ... Soil pH, one of the most routine measurements performed, is used to interpret chemical reactions, nutrient availabilities, and the rates of many biological processes in soils. Predominantly, soil pH is measured in soil–water suspensions using a glass H⁺-sensing electrode and a reference electrode. Soil/water ratios of the suspensions ranging from saturated paste to 1:5 are used in research and com ...

- Abstract:
- ... Phosphorus flux from agricultural landscapes to surface waters may cause eutrophication. In the northeastern United States, P transport largely depends on P sorption of soils in variable source areas or in land treatment systems. Soil redox fluctuation commonly occurs in these areas. Nevertheless, the effect of soil redox on P sorption has been variable in the literature. This study investigated P ...

In the course of investigating nutrient availability in a montane meadow ecosystem of the Sierra Nevada range, it was determined that resin availability of Na⁺ and K⁺ was significantly affected by season (winter vs. summer and fall). The underlying mechanism(s) controlling this seasonal effect was investigated in the laboratory. Four replicate A horizon samples of a Typic Humaquept (silty clay tex ...

To quantify the consequences of erosion and vegetation restoration on ecosystem C dynamics (a key element in understanding the terrestrial C cycle), field measurements were collected since 1959 at two experimental sites set up on highly disturbed barren land in South China. One site had received vegetation restoration (the restored site) while the other received no planting and remained barren (th ...

Recent studies suggest that mineral soils of temperate ecosystems have a limit in C sequestration capacity, and we reasoned that C saturation will be most evident in soils that are already rich in soil organic C (SOC) and have been exposed to a broad range of C inputs. Therefore, we determined soil C saturation in an agricultural experiment located in Ellerslie, AB, Canada, where organic-matter-ri ...
