Soil quality impacts of agricultural and municipal biosolids applications

Trophic levels of the soil food web (Source: nrcs.usda.gov)
Soil health management refers to the preservation and improvement in soil physical, chemical, and biological properties to maximize the productive capacity of soil. Cover crops and reduced tillage are promoted for improving soil health; however, soil amendments such as application of livestock manure and municipal biosolids have received less attention as a soil health improvement practice. A literature review, funded by the North Central Region Water Network and the Soil Health Institute, was conducted to summarize and discuss results of studies reporting chemical, physical, and biological soil properties from application of livestock manure, animal by-products (i.e. compost), and municipal biosolids and to identify further research needs.

Utilization of Woody Biomass as an Agronomic Land Treatment and Conservation Practice in the Middle Niobrara Natural Resources District Long Pine Creek Watershed

spreading woody biomass
A value-added market for woody biomass (wood chips) generated during management of Eastern Red Cedar and native trees in riparian forests and rangeland is critical to offset the cost to landowners of managing forested areas for fire prevention, invasive plant species control, improving wildlife habitat and ecological preservation. Utilization of wood chips alone and co-mingled with livestock manure or nitrogen fertilizer is being investigated (since 2015) as a land treatment practice on local landowner crop fields with research focused on evaluating impacts on soil moisture holding capacity, temperature, biology, & other properties that impact crop productivity.
