Understanding and Managing Soil Biology for Soil Health and Crop Production

The functions of the soil food web and key components in promoting soil health and fertility and sustainable organic crop production, with research-based guidance on organic practices and NOP-approved inputs for improved soil food web function.

The goal of the guidebook is to help organic farmers navigate the wilderness of soil life and soil health management by providing up-to-date, science-based information on:

• The soil food web, its key components, and functions.
• Assessing and monitoring soil life and soil biological condition.
• Managing soil life for long term soil health and productivity in organic systems.
• Biological management of plant diseases.
• Microbial inoculants and biostimulants: whether, when, and how to use them.

Organic Practices for Climate Mitigation, Adaption, and Carbon Sequestration

Climate change threatens agriculture and food security across the U.S. and around the world. Rising global mean temperatures have already intensified droughts, heat waves, and storms, and altered life cycles and geographical ranges of pests, weeds, and pathogens, making crop and livestock production more difficult. Intense rainstorms aggravate soil erosion and complicate water management, and higher temperatures accelerate oxidation of soil organic matter. Warming climates modify crop development regulated by growing degree-days or “chill hours,” and threaten production of perennial fruit and nut crops that have strict chilling requirements to initiate growth and fruit set. Thus, agricultural producers have a major stake in efforts to curb further climate change, as well as improving the resilience of their farming and ranching systems to the impacts of climate disruption.
