Sludge Stabilization Process, Drying Depth and Polymeric Material Addition: Implication on Nitrogen Content, Selected Chemical Properties and Land Requirement in Sand Drying Beds Open
Drying beds are a simple and economical means to dewater municipal sludge and are widely used in places with a suitable climate for air-drying. However, research-based information on drying thickness/drying depth effects on nutrient conten…

Soil Carbon and Nitrogen Fraction Accumulation with Long‐Term Biosolids Applications Open
Core Ideas Biosolids N contribute to wheat grain and soil N. Applied biosolids contain light fraction and non‐hydrolyzable C and N. Biosolids C efficiently increased soil C at 0.91 Mg C in soil per Mg C in added biosolids. Buildup of non‐h…

Potential carbon sequestration and nitrogen cycling in long-term organic management systems Open
The fertility and soil health of organic agroecosystems are determined in part by the size and turnover rate of soil carbon (C) and nitrogen (N) pools. Our research contrasts the effects of best management practices (BMP) (reduction in soi…

Urban Highway Roadside Soils and Shrub Plantings Enhanced by Surface-Applied and Incorporated Organic Amendments Open
Degraded, highly compacted soils along roadsides present an inhospitable environment for trees and shrubs and lead to the failure of urban landscapes. Developing and testing practices to ameliorate urban soils, thereby improving plant grow…

Soil Parameter Mapping and Ad Hoc Power Analysis to Increase Blocking Efficiency Prior to Establishing a Long‐Term Field Experiment Open
The spatial heterogeneity of soil and weed populations poses a challenge to researchers. Unlike aboveground variability, below‐ground variability is more difficult to discern without a strategic soil sampling pattern. While blocking is com…
