The effect of liming on soil phosphorus use efficiency and cycling

To characterize changes in soil P availability and P use efficiency in field plots limed to potentially control root rot; to characterize soil P pools and soil microbial P dynamics in field plots limed to potentially control root rot; to complete greenhouse study with different liming agents, P fertilizer types/rates and crop rotations to optimize P use efficiency; to develop management tools/practices to control root diseases without impacting P use efficiency; to conduct field tests of lime application methods.
