Evaluating Conservation Agricultural Management for Soil Health Outcomes in Southeastern Virginia
Improving soil health in agricultural soils is vital as the effects of climate change and an increasingly affluent population are putting a strain on land resources. Conservation agricultural practices such as cover cropping and conservation tillage systems (e.g., strip tillage, minimal tillage, or …

Disentangling Perceived and Measured Soil Health in New York City Urban Farms
Soil contamination is often addressed by constructing new compost-based soils for urban agriculture. We examined these constructed soils to assess soil health across a diversity of farming sites across New York City, consulting with farmers to characterize their soils as “healthy” or “unhealthy” …

Legume integration and nutrient management impacts on soil health and cropping system productivity
Soil degradation threatens food security and livelihoods in sub-Sharan Africa and in smallholder farming systems globally. Thus, proper management of soil is critical for supporting long-term crop production and addressing multiple sustainability challenges in these agricultural systems. …

Nematodes as indicators of sustainable soil health management practices in corn-soybean production
Soil nematodes are multicellular organisms causing significant economic and ecological impacts, and their community composition is widely used as a bioindicator of soil health. Current methodologies for nematode assessment require further refinement and advancement. This thesis addressed knowledge …

Interactive Effects of Cover Crops, Invertebrate Communities and Soil Health in Corn Production Systems
… on a systems level. Encouraging biodiversity and soil health is the goal of many agricultural practices used in regenerative farming; regenerative systems employ practices which abide by the two main principles of increasing biodiversity and decreasing disturbance, with the goal of encouraging …

Demonstrating Short-term Impacts of Grazing Cover Crops on Soil Health in South Dakota
… Great Plains. This conversion can reduce soil health and increase the region’s ability to pollute the Missouri and Mississippi rivers. Therefore, the need for integrated crop livestock (ICL) practices that can protect the region’s native prairies are strongly encouraged. Introducing …

Biochar amendment as a tool for improving soil health and carbon sequestration in agro-ecosystems
… and land-use conversions drive carbon out of soil and into the atmosphere, where it contributes to climate change. Biochar, a soil amendment produced by pyrolyzing organic feedstocks under low-oxygen conditions, is a promising tool to restore soil carbon and draw down atmospheric carbon …

COMPOST QUALITY RECOMMENDATIONS FOR REMEDIATING URBAN SOILS
Poor soil health is a critical problem in many urban landscapes. Degraded soil restricts plant growth and microorganism activity, limiting the ability of urban landscapes to perform much needed ecosystem services. Amending soil with compost can increase infiltration, microbial biomass, cation …

Soil microbial community dynamics in response to cover crop implementation and P fertilizer management
Soil microorganisms facilitate nutrient cycling within soils providing a critical component of soil health and serve a key role in maintaining productive agricultural systems. There are many ways to assess soil health and how soil systems respond to agricultural management practices. Some of these …
