This report, published by the University of Arizona, outlines a field study evaluating how three years of poultry manure application affected soil minerals in a flood-irrigated sandy-loam pastureland. It discusses changes in soil pH, CEC, and nutrient levels, nitrate leaching risks under flood irrigation, and best management practices for using manure safely and effectively.

In this webinar, plant breeders will discuss how they are meeting the many challenges involved in breeding organic tomato varieties capable of resisting disease, sustaining high yields, and maintaining good flavor. Presenters will discuss some of the lessons they've learned and strategies they are using to overcome these challenges as part of a USDA OREI-funded Tomato Organic Management and Improvement Project.

Field experiments were conducted at the Cal Poly Organic Farm in San Luis Obispo, California, to examine the effects of soil solarization and sudangrass residues on weeds, Verticillium dahliae populations, plant health, and yields in organi…

Biochar, a byproduct of the pyrolysis of crop residues or animal waste, has gained significant interest in recent years as a climate-smart soil amendment; however, its effects on soil greenhouse gas emissions are not well understood. This study evaluated the combined effects of organic cotton residue biochar, cover crops, and poultry litter on soil CO2, N2O, and CH4 emissions.

Conventional strawberry nurseries have used fumigated soils for decades, employing methyl bromide, chloropicrin, Telone, and other highly toxic synthetic chemicals. These nurseries are the primary source of transplants for both conventional…

Biostimulants are substances that, when applied to plants or to the rhizosphere, can enhance nutrient uptake and nutrient use efficiency. This study, conducted by the University of Arizona, Yuma, investigated the effects of biostimulant application on the growth, development, and yield of iceberg lettuce under organic and conventional production systems.

Crop insurance can be a confusing program for organic farmers. In this free online course prepared by the Organic Agronomy Training Service (OATS), learn about: the organic crop insurance cycle (from application to claim), crop insurance programs (i.e., revenue protection, livestock, hail), coverage limitations and practice restrictions, benefits unique to organic producers, and the role of crop insurance agents.

In this episode of Voices from the Field, Grace Brown, the founder of Uncle Paul’s Agritourism & Educational Farm in Tyler, Texas, talks with NCAT Sustainable Agriculture Specialist Justin Duncan about how she overcame various risks on the farm by choosing the right crops – both for the local environment and in accordance with the needs of their clientele.
