A target pH of 6.0 is recommended for most Agronomic crops. However, a lime recommendation for pH 6.5 is also provided on this soil test report. Liming to pH 6.5 helps reduce low pH areas in highly variable fields.

Ratio

For Spanish and runner type peanuts, when a soil test from the pegging zone (3-inches deep) 10-14 days after planting shows a soil calcium level less than 500 pounds per acre or when the Ca:K ratio is less than 3:1, broadcast 160-200 pounds of calcium (Ca) as gypsum per acre or band 80-100 pounds per acre in a 16 to 18 inch band over the row at the early bloom stage.

For all large-seeded Virginia types broadcast 320-400 pounds calcium (as gypsum) per acre or band 160-200 pounds in a 16 to 18 inch band over the row regardless of the soil calcium level.

Organic Production Systems

Inorganic fertilizer recommendations can be converted to organic fertilizer recommendations using the publication: "How to Convert an Inorganic Fertilizer Recommendation to an Organic One", Cooperative Extension Circular 853 (https://extension.uga.edu/publications/detail.html?number=C853). This circular lists a variety of organic fertilizers, some of which may not be approved for use in the USDA Certified Organic Program. Approved fertilizers are listed on the OMRI website – https://www.omri.org. Always check with your certifier before using new fertilizer materials.

For additional information about N credits from cover crops and how to calculate them, see: https://aesl.ces.uga.edu/publications/soil/B1466.pdf

Soil test results do not include nitrogen (N) because the amount of plant available N in soils can change quickly due to unpredictable weather conditions such as heavy rainfall; consequently, tests of plant available N taken weeks ahead of planting are not reliable and do not correlate well with crop yields. Instead, inorganic N fertilizer recommendations are based on many research trials of crop yield response to N fertilizer rates. These trials and the resulting recommendations do not account for N available from a previous cover crop because N from cover crops varies from season to season. N fertilizer rates should be reduced by the amount of N available from a cover crop. This is called N credit.

For information on cover crops, see:

The fertilization strategy may depend on whether the field is in a soil building or soil maintenance stage. New and transitioning growers often have fields that need more soil organic matter and available nutrients. These soils are moving to a new biological and chemical equilibrium. Follow fertilizer recommendations if fields are in the soil-building stage. Fields are likely in the soil building stage if:

Many organic growers reduce fertilizer use by 10 to 20% in the soil maintenance stage. The percent reduction depends on site specific conditions such as the amount of soil organic matter buildup and nutrients available as well as yield goals.

Soil pH should be maintained in the range recommended for specific crops so that they can best utilize the nutrients present in the soil.
