A single fertilization program will not fit all pastures. This guide gives an overview of nutrient management for new and existing pastures, including general recommendations for nitrogen, phosphorus, potassium, sulfur, boron and lime applications.
It is nearly impossible to determine the rate and type of fertilizer that should be applied to pastures and hay fields without first taking a soil sample and having it analyzed. Learn how to take a soil sample, where to have the sample analyzed and how to interpret the results by checking out the Soils page on this OSU Extension Service Small Farms website.
Parts of Oregon are known to have soils that are deficient in the essential micronutrient selenium, and this causes symptoms of selenium defienciency in livestock grazing or fed crops raised on them. Read science based data from an Oregon study focused on applying selenium fertilizer to pastures to reduce deficiencies in livestock.
Soil acidity may be on of the factors that limit yield and growth responses to applied fertilizers. Lime is applied to reduce soil acidity. Pasture soils in western Oregon often require lime for improved yields. Learn about lime materials, types of fertilizer and rates of application in this publication.
This article, based from research completed by OSU Extension Service faculty, explores lime needs and benefits from lime application on pastures using data from several counties along the Oregon coast.
Nutrient Cycling in Pastures (ATTRA)
Good pasture management practices favor effective use and recycling of
nutrients. Nutrient cycles important in pasture systems are the water,
carbon, nitrogen, and phosphorus cycles. This publication provides
basic descriptions of these nutrient cycles then provides guidelines
for managing pastures to enhance nutrient cycling efficiency for
productive forage and livestock growth, soil health, and water quality.
This technical note provides methods to determine biological activity
of pasture soils and practical tips on improving the usefulness of
typical soil and plant samples. The soil biology sampling methods are
easy to learn, and utilize commonly available tools found around any
farm. Once these biological assessments are made, more insight into the
many benefits of nutrient cycling become apparent. Methods for using
soil and plant samples strategically are also covered.
