Pre-transplanting phosphorus application is a fertilization method that can reduce phosphorus (P) fertilization of the field and increase P use efficiency. We investigated whether P use efficiency can be increased further by combining pre-transplanting phosphorus application and the green manure practice, using cabbage as a test plant in a field experiment performed from 2006 to 2008. The pre-transplanting phosphorus application successfully reduced P fertilization of the field to half without any yield losses in 2006 and 2008. However, growth and yield could not be maintained with the pre-transplanting phosphorus application when P fertilization was halved in 2007. Differences among seasons and discrepancies in the results compared to previous studies may have arisen from the differences in the field management and the nursery soil used. No benefits of green manure in terms of the subsequent cabbage yield were detected. Consequently, there was no positive effect of the combination of pre-transplanting phosphorus application and incorporation of green manure. Studies with mycorrhizal plants as test plants may be necessary to verify the mechanism of enhanced P supply by the incorporation of green manure, and to examine any potential benefit of combining green manure and pre-transplanting phosphorus application practices.
