| Résumé : | We analyzed the linearity of relationships between soil test P (STP) and cumulative phosphorus (P) budget using data from six long-term fertilized grassland sites in four countries: France (Erce and Gramond), Switzerland (Les Verrieres), Canada (Levis), and Finland (Maaninka and Siikajoki). STP was determined according to existing national guidelines. A linear-plateaumodel was used to determine the presence of deflection points in the relationships. Deflection points with (x, y) coordinates were observed everywhere but Maaninka. Above the deflection point, a significant linear relationship was obtained (0.33 |
