dc.description.abstract | Overcoming the consequences of future scarcity of P is crucial to ensure agriculture sustainability. This requires
decision-making processes depending on data on the P status of agricultural fields, commonly conducted with
soil P tests (SPTs), and efficient use of the resource on a societal scale following a circular economy approach. All
this will decrease the P losses and the subsequent environmental impact. However, SPTs are not universal and,
even for a given SPT, the definition of threshold values for fertilizer response is not accurate. This work aimed to
define models to predict Olsen P threshold values, allowing the identification of P-responsive sites at the European scale as a basis for more accurate and sustainable P fertilization schemes based on a circular economy
approach. To this end, a data set was compiled based on a literature review that describes the Olsen P threshold
values for different crops under field conditions. Subsequently, an analysis of potential P fertilizer requirements
was performed on agricultural soils of the European Union (EU) using the data set of the LUCAS project and how
this need can be covered with a circular economy approach.
Environmental factors were more relevant than crops to explain the variation in threshold values. A regression
model involving soil pH and clay content and annual average rainfall as independent variables explained 61% of
the variance in Olsen P threshold values. When soil pH and clay content were the only explanatory variables, the
explained variance was 49%. This reveals the need to take into account factors related to P buffer and sorption
capacity to estimate accurate threshold values. We detected that only 27.8% of EU cropland soils and 42.7% of
grassland soils were P-responsive. We can conclude that a more precise allocation of the resource is possible in Presponsive sites and also that most of the European demand for P could be covered by recycling P from manure,
wastewater, and municipal solid waste. | es |
