Europe
In Western Europe, a series of surveys
and agronomic research projects on phosphate fertilizer
management in P-enriched soils were carried out in cooperation
with several National Agricultural Research Centers.
These undertakings provided a rationale for maintenance
of optimal soil fertility and productivity using best
management practices that preserve the environment.
This was demonstrated through a network of field experiments
and laboratory studies that assessed the effects of
withholding P fertilizer on crop yields and plant-available
P in various soils of Western Europe, and dealt with
the different components as cited below:
