Understanding the. Soil Test Report. Crops absorb the nutrients required from soil in order to grow, so ensuring that your soil is meeting the crops’ needs is critical. Having the proper level of nutrients in the soil will help to produce optimum quality yields. Testing your soil at least every three years, if not annually, is the best way to ...

1. appm = parts per million 2. BRating of probability of profitable crop response from added fertilizer based on the extracted nutrient level: VR = very high response, HR = high response, MR = medium response, LR = low response, RR = rare response, NR = no response 3. OR may also be rated based on extracted nutrient level as VL = very low, L = low, M = medium, H = high, VH = very high, E = excessive 4. cmilli-equivalents per 100 g soil (meq/100g)
When a soil sample is submitted to the lab, it is dried and ground and a variety of extractions are performed on small "sub-samples". It's important to bear in mind that these sub-samples may be as little as 2 grams of soil, so it is critical to obtain as representative a sample as possible. The extractants pull the easily available and some of the...
OMAFRA fertilizer guidelines, which can be found in Publication 811, are based on the sufficiency approach, which provides the greatest potential economic response in a given year based on crop and soil test level. Depending on your situation, you may want to invest in raising soil test levels for phosphorus or potassium. A recent review of decades...
EC measures the ability of water to conduct electricity. This is affected by the amount of dissolved salts or impurities. Units are micro-Siemens per cm (µS/cm) or milli-Siemens/cm (mS/cm). 1 mS/cm = 1000 µS/cm. Units may also be written as mmho/cm (1 mmho/cm = 1 mS/cm) and deciSiemens/meter or dS/m (1 dS/m = 1 mS/cm).

Dec 14, 2020 · Soil pH is measured in distilled water and reflects the active acidity in the soil. If the pH on your soil test report is less than 5.5, you may get a lime recommendation, depending on your crop. The lime recommendation is the amount of 100% effective calcium carbonate equivalent (ECCE) lime that is required to raise the pH to a level your crop ...
SOIL TESTS & INTERPRETATION This technical note discusses most of the soil tests used at Hill Labs, and gives very general interpretive information for each. Information for this Technical Note has been taken from Chapter three of the Field Consultants Guide to Soil & Plant Analysis. Hill Labs has organised its soil tests into two groups.

Soil Sampling and Lab Testing To obtain quality soil test results, the soil samples must be taken properly. Each sample must be representative of the entire field or specified sampling unit. The samples must also be taken at the proper depth during the same time frame every year. Sample depth can vary by test but is usually within 6-12 inches ...
