Improving the efficiency and effectiveness of global phosphorus use: focus on root and rhizosphere levels

Uwe LUDEWIG, Lixing YUAN, Günter NEUMANN

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 4,   Pages 357-365 doi: 10.15302/J-FASE-2019275

Abstract:

Phosphorus (P) is essential for life and for efficient crop production, but global P use with limitedUnfortunately, plant physiologists, agronomists, farmers and end users employ different measures for P useefficiency (PUE), which often masks their values at different scales.The term P use effectiveness, which also considers energetic and sustainability measures in additionThe desired concentration of P in the products differs, depending on the final use of the crop products
