Mo contents of some crops and grassland plants of Schleswig‐Holstein in relation to soil factors . The Mo content of about 170 plant samples of typical soils of Schleswig‐Holstein were in the range of 0,2–11 ppm, increasing from grass to red clover, white clover and rape. By comparison with limiting values for adequate Mo supply (0,3 ppm Mo for red clover and probably also for the other three plants), a fairly good supply of the plants investigated can be deduced. The factors responsible for the varying Mo contents of plants are first of all the pH‐value, furthermore the content of active iron and available phosphorus in the soil. The different contents of oxalat‐soluble Mo had apparently no influence in this range of good supply. Whereas the correlation between one soil factor and plant Mo content was high only in some cases, coefficients of determination of up to 80% resulted from the use of several factors by multiple correlation.
