Biosolids as a source of soil conditioning and fertility for turfgrass
… rehabilitate anthropogenically disturbed urban soils for improved plant growth and effects on the cycling of nutrients requires further study. Our objectives were: 1) to determine whether various EQ biosolids could be managed to improve degraded soil properties and turfgrass quality while …

Local polysaccharide-producing soil cyanobacteria as potential soil conditioners in Nakhonsawan Province, Thailand
… algal strain, and demonstrates its soil-conditioning potential in a greenhouse environment. The results show that local algal resources have potential as soil conditioners. The process involved surveying soil algae to identify potential candidates, selection of the most suitable …

Geochemical changes, plant growth and ecosystem recovery in soils after high temperature remediation
… treatments generate elevated temperatures in the soil (40-1200°C) that may impact its quality, particularly its ability to support plant growth and microbial activity. This thesis demonstrates the effects of such heating on soil properties, the impact on plant and microbial systems, and potential …

Examination of excavation chamber pressure behavior on a 17.5 m diameter earth pressure balance tunnel boring machine
… through till and till-like deposits, granular soils, and cohesive silts and clays. A portable laboratory was established on the project site to characterize key properties of the muck as it came through the screw conveyor and onto the belt conveyor, namely, vane shear strength, density, slump, …

Developing a system to measure rheology of conditioned soil for soft-ground TBM tunneling
… rate. To modify the behaviors of the muck, soil conditioners are often injected to the tunnel face and the machine chamber so the conditioned muck will exhibit certain properties such as good balance between flowability and viscosity, low abrasiveness, and low stickiness. There is no …

Impacts of Invasive Asian Jumping Worms on Soil Properties in Turfgrass Systems and their effects on Plant Nutrient Acquisition and Physiological Responses in Greenhouse Experiments
… abundance, microbial enzyme activity, soil chemical and physical properties, and turf condition. The study was conducted at four residential sites in southwest Virginia, each with garden bed infestations and adjacent turfgrass lawns. Sampling occurred in May and September 2024. At each …

Analysis of soil compaction and furrow depth from planter row unit
… such as furrow formation, seed placement, and soil-conditioning during planting. It affects seed spacing and singulation, root growth, emergence, crop health, yield, and field traffic management. This study analyzes how the planter row unit’s operation affects soil compaction, furrow depth, and …

Algal sludge disposal in waste-water reclamation
… investigated: (1) to evaluate its potential as a soil conditioner; (2) to determine whether a stabilization lagoon could be used for algal sludge disposal; and (3) to determine whether or not sludge recirculation would reflect a chemical savings. The experimental lagoons and treatment facility, …
