Livestock Grazing as a Tool for Healthier, More Resilient Orchards
Healthy soil is the backbone of a productive orchard. It supports strong root systems, improves water infiltration, cycles nutrients efficiently, and increases resilience to drought and pests. Across California’s working landscapes, growers are turning to livestock grazing as a cost-effective, NRCS-supported strategy to improve orchard soil health while reducing inputs and management costs
The USDA Natural Resources Conservation Service (NRCS) emphasizes four core soil health principles that apply directly to orchard systems:
Keep the soil covered
Minimize soil disturbance
Maintain living roots year-round
Increase plant and biological diversity
Orchards that follow these principles tend to experience improved water holding capacity, reduced erosion, healthier microbial communities, and more consistent yields over time.
When managed carefully, livestock grazing supports all four NRCS soil health principles while offering additional operational benefits.
Improved Nutrient Cycling Livestock return nutrients directly to the orchard floor through manure, feeding soil microbes and increasing organic matter. This natural fertilization improves nutrient availability for trees and reduces reliance on synthetic inputs.
Better Water Infiltration and Soil Structure Soils with higher organic matter absorb and store more water. Grazed cover crops help build stable soil aggregates, allowing irrigation and rainfall to move deeper into the soil profile rather than running off.
Reduced Vegetation Management Costs Sheep and other livestock can replace mechanical mowing and some herbicide applications, lowering fuel use, labor costs, and equipment wear.
Increased Biodiversity and Resilience Grazed cover crops promote diverse plant communities and beneficial insects, strengthening orchard ecosystems and improving resilience to pests and climate extremes.
“Healthy soils are living soils — and livestock help bring them back to life.”
NRCS-Supported Best Practices for Orchard Grazing
To maximize benefits and avoid soil compaction or crop damage, NRCS recommends the following best practices:
Rotational or managed grazing: Move livestock frequently to prevent overgrazing and allow vegetation recovery.
Seasonal timing: Winter or dormant-season grazing is often ideal; remove animals well before bloom or harvest.
Appropriate stocking rates: Match animal numbers to forage availability and soil conditions.
Diverse cover crops: Multi-species mixes improve forage quality while supporting soil biology.
Monitoring soil conditions: Avoid grazing when soils are saturated to prevent compaction.
Livestock grazing is more than an alternative weed control method — it is a soil health strategy aligned with NRCS conservation principles. When paired with cover crops and thoughtful management, grazing can improve soil function, reduce costs, and strengthen orchard systems for the future. NRCS and local Resource Conservation Districts can provide technical assistance and cost-share opportunities for growers interested in integrating grazing and soil health practices into their orchards.
