In order to guarantee productivity and soil quality, soil needs to be supplied with adequate phosphorus reserves. Soil analysis helps determine optimal fertilization and helps reduce soil P losses. A study carried out in the Netherlands is presented below. The P-Al test has been used for a long time in the Netherlands to measure P soil reserves that are partially available during the vegetation period (P capacity). The mean P-Al level of grassland soil has barely changed between 1970 and 2010 ('adequate' level), but with wide disparities between regions and different types of soil. Several methods of analysis were compared. Previous studies suggest the idea of combining tests measuring readily available soil phosphorus (P intensity:P-CaCl2) with tests extracting available P(P-Al or P-Olsen) in order to optimize efficient use of P. Combining 2 methods of soil analysis will help improve fertilization recommendations and environmental assessment of these practices. This will soon be introduced and monitored further.
