• EXPLANATION OF SOIL TEST REPORT <br />SOIL CHEMISTRY UNITS <br />ppm=part per million=l pound of element to one million pounds <br />of soil 1 ppm is equivalent to 2 lb./acre 6-7" or 3.5 lb./acre <br />foot Meg/1008=Milligram equivalents per 100g soil <br />Mmhos/cm3=Millimhos per cubic centimeter specific conductance <br />INFORMATION FROM DATA SHEET: <br />This data is transferred directly from the data sheet <br />submitted with the soil sample. information with respect <br />to yield goal, planting date, manure and fertilizer applied, <br />previous crop and residue, method of irrigation, and method <br />of fertilizer application, is directly related to recommending <br />fertilizer application to provide adequate plant nutrients <br />for the proposed crop. <br />Cow manure is valued on the basis of 5 lb/ton N, 2 lb/ton <br />P205, and 5 lb/ton potash. if manure to be applied is dry, <br />not diluted with soil or excessive straw, and has not been <br />leached, these values can be increased up to 1008. <br />• Other manures are valued according to their average <br />analysis. <br />GENERAL ANALYSIS: <br />Texture - LoSn, SnLo (light); Lo, Silo, SnC1Lo, C1Lo (medium); <br />SnCl, SiCl, C1 (heavy <br />pH(H20) - This is the normal soil pH indicating acid (less than <br />-~, neutral (near 7), alkaline (over 7) or free lime (over 8). <br />Best range for most crops is pH 6-7. <br />Ph(salt) - Used in conjunction with pH(H20) as an indicator <br />of excess soil salts. If the two are nearly the same, <br />high salts are indicated. <br />pH (buffer) - Used to calculate the lime requirement for acid <br />soils. <br />CEC - Cotion exchange capacity (FEC Field exchange capacity) - <br />an index of the soils ability to store exchangeable <br />cations (ammonium, potassium, calcium, magnesium, sodium <br />and acidity). Varies from about 3 in very light soils <br />to about 30 in heavy high OM soils. <br />SALT - An index of excessive soluble salts in the soil water. <br />• Poor germination and reduced growth may be expected <br />according to the following table. <br />7-3-3 <br />
