Slow infiltration rates constrain effective and economical irrigation in some sandy loam soils in California. Polyacrylamide (PAM) has increased soil infiltration in some areas, especially in soils high in clay or silt. Field trials near Fresno, CA, with PAM failed to show improved infiltration. Laboratory experiments were conducted to investigate PAM effect on infiltration of various quality w...

Abstract The diel dynamic of the CO 2 concentration in soils relation to temperature is not yet fully understood. Air might control soil due thermal convective venting at sites experiencing large differences between atmosphere and soil. Therefore, objective this study was determine its temporal a deep desert relationship air based on high frequency measurements. For purpose, were measured six d...

Comprehensive estimates of forest carbon (C) mass and respiration require measurements of all C pools, including coarse woody debris (CWD). We used inventory and chamber-based methods to quantify C mass and the annual respiratory C loss from CWD and other major ecosystem components for a deciduous forest in the upper Great Lakes region. Coarse woody debris mass (MCWD, 2.2 Mg C ha ) was less tha...

Abstract Purpose Tackling the global carbon deficit through soil organic (SOC) sequestration in agricultural systems has been a focal point recent years. However, we still lack comprehensive understanding of actual on-farm SOC potentials order to derive effective strategies. Methods Therefore, chose 21 study sites North-Eastern Austria covering wide range relevant arable types and determined po...

In developing country like India due to the remarkable development in road infrastructure, Soil stabilization has become the major issue in construction activity. Stabilization is an unavoidable for the purpose of highway and runway construction, stabilization denotes improvement in both strength and durability which are related to performance. Stabilization is a method of processing available ...

Organic amendments (animal manure and biochar) to agricultural soils may enhance soil organic carbon (SOC) contents, improve fertility crop productivity but also contribute global warming through nitrous oxide (N2O) emission. However, the effects of on N2O emissions from seem variable among numerous research studies remains uncertain. Here, eighty-five publications (peer-reviewed) were selected...

Insufficient water is the greatest limitation to crop production and choice of crops grown in the Northern Great Plains. Supplemental irrigation can overcome this limitation. Uncertainties about the drainage capacity of flne-textured subsoils and the effect of irrigation on soil properties has impeded irrigation development. In this study we quantified salinity changes in soils with fine-textur...

1 Recent studies demonstrated the sensitivity of northern forest ecosystems to changes in the amount and duration of snow cover at annual to decadal time scales. However, the consequences of snowfall variability remain uncertain for ecological variables operating at longer time scales, especially the distributions of forest communities. 2 The Great Lakes region of North America offers a unique ...

The vertical migration of N. carpocapsae infective juveniles applied to the soil surface or introduced 14 cm below the soil surface was studied in four different soil types (pure silica sand, coarse sandy loam, silty clay loam, and clay). The percentage of juveniles able to migrate and infect wax moth pupae placed in the soil decreased as the percentage of clay and silt increased. Most nematode...
