NCAT’s Small-Scale Intensive Farm Training program (SIFT) operates a high-altitude urban demonstration farm in Butte, Montana, that is focused on production of food for the good of the community. This publication provides details on the role that the farm plays in educating and producing food for the community. It highlights ongoing cover crop experiments, fruit tree propagation, and water-conservation strategies at the farm, as well as construction of a new high tunnel.… Read the rest

Economic Considerations of Growing Bee-Friendly Cover Crops in Almond Orchards: Grower and Beekeeper Perspectives

Authors: Marieke Fenton and Brittney Goodrich

View full publication here: s.giannini.ucop.edu/uploads/pub/2023/02/15/v26n3_3.pdf

Planting bee-friendly cover crops in almond orchards can improve honey bee colony health and lower beekeepers’ costs of feeding, while also providing soil health benefits. However, for the full bee-health benefits to be realized, growers must plant in the fall and receive timely rains or have access to irrigation between orchard rows. In this publication, the authors review benefits and considerations for both growers and beekeepers of this potentially mutually beneficial practice.… Read the rest

Cover crop calculator – Economics

This interactive calculator is a decision-support tool that estimates the costs and benefits of winter cover cropping in almond and processing tomato operations in California’s Central Valley. The tool estimates how much farmers can expect their profits to change after growing winter cover crops for a certain number of years. All values that are used in the calculator are flexible and can be adjusted to match the reality on your farm. The tool was designed for farmers who are interested in growing winter cover crops and who want to understand how long it will for that investment to break even. … Read the rest

Overcoming Barriers to Cover Crop use in Hazelnut Production

Authors: Shannon Cappellazzi, Abigail Tomasek, Nik Wiman

This project will collect and communicate information that will help producers incorporate cover crops into hazelnut production. We will conduct a survey to identify the major barriers for grower adoption and aggregate data on the methods and practices local producers are using to make cover crops work. We will conduct follow up interviews to create a partial budget analysis comparing net farm profitability after a change to new practices. We will perform in-field soil health assessments, and collect soil and tissue samples from interested growers’ fields. This analysis will provide data to demonstrate … Read the rest

Cover Crops Database – UCANR

In an effort to make information on specific cover crop species available and easily accessible, the UC Sustainable Agriculture Research and Education Program created the cover crop database, first released in 1999 (and it remains one of the most highly visited features of UC SAREP’s extensive website). The database contains detailed entries for over 40 commonly used cover crop species. For each crop, a summary of key factors is provided, including: Seed, seedling and mature plant descriptions and pictures Ideal temperature and geographic range Soil, water and nutrient considerations Management details including planting and termination dates, maintenance issues, mowing, … Read the rest

Building on Farmer Experience to Increase Cover Crops Adoption in Orchards and Vineyards

Sonja Brodt, UCANR

This project is creating an online searchable database of best management practices as implemented in California’s southern Sacramento Valley and North Coast regions, by orchard and vineyard growers experienced in cover cropping. The project will also provide detailed case studies of grower cover cropping strategies, organize field tours of successful cover cropping operations, and link to information on the latest cover crops research.… Read the rest

The OSU Forage Information System project draws on Oregon Extension and research faculty with assignments in the areas of forage and livestock systems to develop an integrated information resource to support forage and livestock system operators, public land managers, and those who advise and support these entities with 24-7 access to accurate, science-based, practical information.

This resource focuses on cover crops and their use in forage production rotations. … Read the rest

Estimated Costs for a winter cover crop in an annual crop rotation

View the full link here: https://coststudyfiles.ucdavis.edu/uploads/pub/2022/09/28/2022covercropsbenefits.pdf

This cost study models the planting and management of a winter cover crop in a summer crop rotation planted in the lower Sacramento Valley of California. The rotation may include processing tomatoes, corn, sunflower, safflower, sorghum, and/or dry beans, as well as other summer annual crops. This study models a field following harvest of processing tomatoes in the fall and a planned rotation into a spring planted field crop.

The most commonly grown cover crop species are selected from three plant families: Leguminosae (such as bell beans, peas, clover, and vetch), Brassicaceae (such as … Read the rest
