This factsheet, published by the University of California, Davis, summarizes results from a research study that quantified how different organic soil amendments release nitrogen and how heirloom tomato plants take up and partition that nitrogen throughout the growing season.

This slide presentation, given by Dr. Amber Vinchesi-Vahl, University of California Agriculture and Natural Resources (UC ANR), outlines cucumber beetle biology and management in organic vegetable systems. It covers basic facts about several species of cucumber beetle prevalent in California and provides practical, on-farm strategies for managing cucumber beetle populations.

This factsheet, published by University of California Agriculture and Natural Resources (UC ANR), outlines the biology, life cycle, and crop damage associated with the invasive Bagrada bug (Bagrada hilaris), with a focus on its impact in Yolo County, CA. It discusses monitoring strategies and cultural, mechanical, and organically-approved control options available to growers.

The guidebook examines the role of rice in both the global and U.S. food system, detailing the current status of domestic organic rice production and the gap between rising consumer demand and limited U.S. supply. It also explores production challenges, insights from multistate farmer surveys, and strategic recommendations to strengthen the organic rice sector.

The guidebook explores how integrating livestock grazing into cover-cropped organic vegetable systems can support soil health and enhance nutrient cycling, while also examining the potential food-safety risks associated with grazing before planting fresh produce. It summarizes a multi-state research project that evaluates soil physical, chemical, and biological outcomes of grazed versus ungrazed cover crops, and discusses practical implementation in organic systems.

The guidebook provides organic citrus producers with science-based strategies for managing Huanglongbing (HLB), also known as citrus greening, using methods compliant with organic certification. It summarizes researcher and grower experience on controlling the Asian citrus psyllid (ACP) vector, enhancing tree health through biocontrols, cultural practices, micronutrient support, and other organic-approved tactics.

This article, published by University of Arizona Cooperative Extension, summarizes a research study comparing water use in organic and conventional iceberg lettuce systems using sensor-guided irrigation. It explains how real-time soil moisture sensors can reduce total irrigation and crop evapotranspiration (ETc) compared with traditional scheduling, and discusses implications for more efficient, sustainable water management in arid agricultural regions.

This factsheet, published by University of Nevada Extension, describes how cover crop species can be used in Nevada to improve soil health, reduce erosion, build organic matter, and support farm resilience while managing water use in an arid climate. It outlines what cover crops are, their benefits and functional groups, and key considerations for tailoring cover crop use to specific farm needs/conditions.

This factsheet, published by University of Nevada Extension, provides small-acreage farmers with guidance on managing weeds without the use of conventional herbicides, focusing on organic-friendly and mechanical control options. It explains the basics of weed competition and outlines a range of non-chemical tactics, including tillage, crop rotation, mulching, precision irrigation, and competitive crop selection.

This factsheet, published by University of Nevada Extension, outlines how produce farms in Nevada can manage/monitor agricultural water to prevent contamination by pathogens such as E.coli and Salmonella that can pose food safety risks. It summarizes key on-farm practices including identifying water uses, selecting water application methods that limit direct contact with edible crops, water quality testing, and recordkeeping.

This report details a multi-year research project conducted by the University of Nevada, Reno, evaluating whether organic lettuce can be grown using row covers and hoop houses during the winter in northern Nevada. It outlines research methods and preliminary results from the trial, highlighting key challenges for growers.

This report, published by the University of Nevada, Reno, summarizes the results from several field trials evaluating how different winter cover crop species perform in Nevada’s high-desert climate, focusing on traits such as cold tolerance, establishment, and biomass production.
