Monitoring Soil Nitrate to Estimate Cover Crop Nitrogen Contribution in Organic Vegetable Production Fields

Authors: Nick Andrews, Dan M. Sullivan, and Kristin Pool, Oregon State University

Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes: solo common vetch (V), phacelia + V (PV), and cereal rye + V (RV), plus a winter fallow (F) control in grower fields in the north Willamette Valley OR. Soil textures were … Read the rest

SIFT 2021: A Small-Scale Urban Intensive Farm Contributes to a Resilient Food System

Authors: John Wallace and Andrew Coggins, NCAT Agriculture Specialists

Read the full publication here: https://attra.ncat.org/publication/sift-2021/

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

Grazing Winter Cover Crops With Sheep to Improve Economic Feasibility in Annual Vegetable Systems

Amélie Gaudin, Associate Professor of Agroecology, Department of Plant Sciences

Sheep grazing of cover crops could provide new ways to offset the cost of winter cover crops in annual vegetable systems while enhancing soil health outcomes. This project compares soil health, foodborne pathogen risk and productivity of 3 winter management strategies (grazed cover crop, ungrazed cover crop, and fallow) in tomato systems. Funded by CDFA Healthy Soils Program (CA Climate Investments)

Soil Nitrate Testing for Willamette Valley Vegetable Production (2019) EM9221

Link: https://catalog.extension.oregonstate.edu/em9221

This publication describes how to use in-season soil nitrate testing to adjust sidedress N fertilizer application rate to match crop N requirements. Data to support our recommendations comes from field trials conducted in the Willamette Valley for vegetable crops produced during summer months.… Read the rest
