Title: Effect of water soluble phosphate on the utilization of rock phosphate by cabbage and rye plants

In soil/rock phosphate systems, all the ? that can be taken up by the plant does not become uniformly labelled because rock phosphate ? exchanges only to a limited extent. In such systems, calculated values do not indicate amounts of labile ? but are indices of the ratios in which rock ? and soil ? are absorbed by the plants. A low L value will, therefore, indicate that relative to soil P, less rock phosphate was absorbed than when a high value is obtained.Read More
