Establishing Reference Guidelines for Phosphorus Fertilization in Organic Crop Production
This study develops new soil phosphorus availability thresholds for organic farming, based on crop responses to soil P supply, showing that organic crops maintain yields at lower P levels than those prescribed by conventional diagnostic methods.
Detalizēts apraksts
Due to the significant decrease in Olsen P2O5 observed in French soils and given that these levels are generally lower in plots managed using organic farming (OF), it is essential to raise awareness among OF farmers about diagnosing phosphorus (P) deficiency to help them better anticipate risky situations. The reference diagnostic method for field crops, as established by Comifer (French Committee for Sustainable Fertilization Study and Development), does not seem well adapted to OF because crop yields are relatively unaffected by low P levels in the soil. To improve P deficiency diagnosis in OF, a study of crops response to soil P supply in OF was carried out and led to the proposal for response to P soil availability thresholds adapted to OF, significantly lower than those currently used in conventional agriculture.
