Farmers are looking for appropriate tools assessing and interpreting the health status of their soils; however, there is no standardized prairie-based soil scoring framework. Accordingly, we focused on developing one arable cropping systems in Saskatchewan. In 2018, samples (0–15, 15–30, 30–60 cm depths) were collected from 55 fields across Saskatchewan, along with native prairie samples. Vario...

Previous research on the relationship between edaphic factors and species diversity patterns has mostly focused topsoil 0 30 cm, with less attention paid to deeper layers where many plant root systems are concentrated. Since considering might help unravel maintenance mechanisms of diversity, in present study we explored vegetation β-diversity a comprehensive set soil chemical attributes at diff...

Leaching and nitrous oxide (N2O) emissions can represent substantial nitrogen (N) losses from chemical fertilizers, slow-release fertilizers (SRFs) mitigate these effects. Thus, biochar be an alternative agronomic environmental point of view to synthesize SRFs due its physicochemical characteristics. We investigated the effect nitrogenous organomineral (OMF-N) formulated based on activated N by...

in order to study the effects of rate and application time of nitrogen on grain yield of rainfed wheat, water use efficiency of rain (wue), nitrogen agronomic efficiency (nae) and soil moisture depletion (smd), one experimental farm was carried out in kurdistan province during 2012-2014. tratments were five rates of nitrogen (n0, n30, n60, n90 and n120) kg.ha-1 as urea with three application ti...

Quantifying and managing carbon (C) storage in urban green space (UGS) soils is associated with the ecosystem services necessary for human well-being and the national C inventory report of the Intergovernmental Panel on Climate Change (IPCC). Here, the soil C stocks at 30-cm depths in different types of UGS’s (roadside, park, school forest, and riverside) were studied in three major South Korea...

Gold-tip electrodes. Radiofrequency (RF) catheter ablation is widely used to induce focal myocardial necrosis using the effect of resistive heating through high-frequency current delivery. It is current standard to limit the target tissue-electrode interface temperature to a maximum of 60-70 degrees C to avoid char formation. Gold (Au) exhibits a thermal conductivity of nearly four times greate...

Sugarcane (Saccharum spp.) is routinely exposed to periodic floods and highwater tables in Florida’s EvergladesAgriculturalArea. Learning sugarcane responses to these conditions will help improve yields. This study evaluated the effects of constant water-table depths, periodic floods, and N on cane and sucrose yields of two sugarcane cultivars. In 2001 and 2002, two foliar N and four water trea...

Larger, and deeper, root systems of new maize varieties, compared to older varieties, are thought to have enabled improved acquisition of soil resources and, consequently, greater grain yields. To compare the spatial distributions of the root systems of new and old maize varieties and their relationships with spatial variations in soil concentrations of available nitrogen (N), phosphorus (P) an...

The prokaryote community activity and structural characteristics within marine sediment sampled across a continental shelf area located off eastern Antarctica (66 degrees S, 143 degrees E; depth range, 709 to 964 m) were studied. Correlations were found between microbial biomass and aminopeptidase and chitinase rates, which were used as proxies for microbial activity. Biomass and activity were ...

The revegetation of abandoned farmland significantly influences soil organic C (SOC) and total N (TN). However, the dynamics of both soil OC and N storage following the abandonment of farmland are not well understood. To learn more about soil C and N storages dynamics 30 years after the conversion of farmland to grassland, we measured SOC and TN content in paired grassland and farmland sites in...
