Soil Health Nexus debuts new soil health resource

The Soil Health Nexus team is making it easier than ever to access valuable soil health information through their newly released Soil Health Toolbox. To date, the team has released resources on conducting on-farm-research that incorporates soil health, and is working on resources on 1) how soil health impacts water quality and flow through the landscape, and 2) understanding and measuring soil’s physical, chemical and biological properties.

Getting to the Science of Soil Health: USDA Releases Standard Indicators and Laboratory Procedures to Assess Soil Health

The enthusiasm for the soil health principles in some cases has gotten ahead of the science behind them. To address this, NRCS and the Agricultural Research Services (ARS) lead a diverse group of technical experts in selecting methods to assess six standard soil health indicators, which focus on key physical and biological process that must function well in healthy soils. The document titled “Recommended Soil Health Indicators and Associated Laboratory Procedures”, Technical Note No. 450 (PDF) was developed by a group of experts and provides information getting us closer to understanding the science behind soil health and how it is best measured.

Building Soil Organic Matter Takes Time

Our “instant” culture gravitates to testimonials about how to rapidly increase soil organic matter by 1% within 1 to 3 years. Conversations with lenders and landlords regarding rewards on manure applications and multi-species cover crops investments would likely be easier if financial rewards or measured soil physical properties came quickly.

Maintaining soil fertility is important for soil health

Maintaining soil fertility is important not only for profitable crop production, but also soil health. In a long-term P and K fertility trial, we can see that there is much greater residue cover in plots that have received adequate potash applications over time compared to where no K was applied. Application of P had minimal to no effect on residue cover.

Research demonstrates that animal manures can produce both environmental and productivity benefits over the commercial fertilizer it replaces.

Manure’s Impact on Yield, Nitrogen, and Carbon

Manure is often viewed by many as an environmental liability.  However, if manure is applied at rates equal to or less than the nitrogen (N) requirement of a crop, can manure produce environmental benefits over commercial fertilizer?  This was the focus of an Asian research group which summarized the results of 141 published studies from Asia, Europe, and the U.S. comparing manure substitution for fertilizer. This article summarizes the “Take Home Messages” from this research paper.

Can Manure Improve Soil Health?

Is there a correlation between soil health (or soil productivity) and manure? A Missouri team analyzed many soil health related variables and manure land application details, based on data collected under the Missouri Cover Crop Cost-ShareRead More…

Soil quality impacts of agricultural and municipal biosolids applications

Background 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,Read More…
