The optimal pH range for most plants is between 5.5 and 7.0. 1. The reported s values are related to the nutrient availability . A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Wait to add the manure until you get the results from the soil test. Higher levels may be needed for especially high yields as well as for certain vegetable crops. Regular soil testing is a critical component of good crop production. Managing soil sodium is really about maintaining optimum levels of soluble soil calcium. In order to amend a sodic soil, sodium must simply be replaced with calcium, which is usually accomplished with high rates of Gypsum (calcium sul-fate). Interpretive levels for soil pH are given graphically on the soil test report in relation to the target pH for the most acid … An accurate soil test will indicate your soil's pH level will specify the amount of lime or sulfur that is needed to bring it up or down to the appropriate level. If in the optimum, growers need to account for the removal of K during the season.
The Learning Store offers educational media developed by Cooperative Extension researchers and staff to support healthy and financially secure families, food safety, environmental issues, agriculture and farming, community and economic development. Soils may require remediation if the soil salt level exceeds the tolerance of the turfgrass being …

When soils from tillage farms were examined separately the improvements in soil pH were greater with up to 83% of samples having optimum soil pH in 207-18. Optimum soil test values for macro- and micronutrients, which vary from soil to soil, crop to crop, and extraction to extraction, are required. Definitions of interpretive ratings for phosphorus and potassium soil tests 18 VIII. Optimum soil test values for macro- and micronutrients, which vary from soil to soil, crop to crop, and extraction to extraction, are required. Also make sure that your raspberries are not too crowded. If the soil test does not give a recommendation for phosphorus and/or potassium, this means that there is enough of these nutrients in the soil to provide the needs of the crop and still maintain the soil test in the optimum range or higher. It allows you to monitor soil fertility levels, identify potential for nutrient deficiencies, and make fertilizer decisions based on the best possible information. 3-N) extracted from soil and reported in oil test analyses are indices. Optimum soil test P levels required by potato and processing crops grown on coarse-textured soils can be considerably greater than for most other agronomic crops. printedon the soil test report; however, with the exceptionof zinc, their levels do not currently affect thefertilizer recommendations.Soil­test zinc levels below4 ppm (8 lb/acre) coupled with pH above 6.0 maytrigger a zinc fertilizer recommendation.Plant tissueand soil analyses should be used together to
