This manuscript presents research results examining phosphorus (P) management in a soil–plant system for three variables: i) internal resources of soil available phosphorus, ii) cropping sequence, and iii) external input (manure, fertilizers). The was conducted long-term sequences with oilseed rape (10 rotations) maize (six over consecutive growing seasons (2004/2005, 2005/2006, 2006/2007) production farm on soils originated from Albic Luvisols Poland. pool, measured as calcium chloride extractable P (CCE-P), constituted 28% to 67% the total (PTI) spring. Oilseed dominant showed significant potential utilize CCE-P pool within profile. Cropping containing significantly affected turn contributed P(TI). P(TI) uptake use efficiency 50% average. Therefore, should be taken into account an important component sound reliable balance. instability yield prediction, based P(TI), mainly due imbalanced both farmyard manure fertilizer. plants provide positive impact after harvest, improving productive stability entire sequence. phenomenon documented by increase during wheat cultivation following rape.
