Summary Most soil tests for available phosphorus (P) perform rather poorly in predicting crop response. This study was set up to compare different established their capacity predict response across contrasting types of soil. Soil samples from long‐term field experiments, the oldest >100 years old, were collected five European countries. The total number ( n = 218), which differed cropping and P treatment, originated 11 types, analysed with tests: ammonium oxalate (Ox), lactate (AL), Olsen...
Abstract Phosphorus (P) is an essential element for plant growth. Low P availability in soils likely to limit crop yields many parts of the world, but this effect has never been quantified at global scale by process‐based models. Here we attempt estimate limitation three major cereals worldwide year 2000 combining information on soil distribution croplands and a generic model, while accounting nature soil‐plant transport. As average, diffusion‐limited supply meets crop's demand corresponding...
Abstract The European Commission has set targets for a reduction in nutrient losses by at least 50% and fertiliser use 20% 2030 while ensuring no deterioration soil fertility. Within the mandate of Joint Programme EJP Soil ‘Towards climate‐smart sustainable management agricultural soils’, objective this study was to assess current fertilisation practices across Europe discuss potential harmonisation methodologies as strategy reduce loss overall use. A stocktake methods delivering advice took...
Abstract Nitrogen (N) budgets at farm level are influenced by N fertilisation recommendations. In this study, we reviewed and analysed the underlying principles methods of recommendations in 10 West European countries, to identify similarities differences, develop suggestions for reconsideration improvement. An analysis national official documents on revealed that there were three main categories calculation methods: (i) ‘N mass balances’ (France, Italy, Spain), (ii) ‘Corrected standards’...

Abstract Many European cropped soils have high soil test P (STP) values in the top because of accumulation over many years fertilizer application. This should allow to save applications for some without STP decreasing a level that might negatively impact crop yield. However, way develops under omitted application is not well understood. We examined development timeframes between 7 and 46 on 96 unfertilized treatments (P0 treatments) 43 long‐term field experiments, using five different...
