  6. 5. Comparing the diffusive gradient in thin film (DGT) method with water and ammonium-acetate-lactate for P extraction and extractable P required for maximum cereal yield using long-term field experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Cornelia Mesmer; [2017]
    Keywords : fertilization; plant-availability; agriculture; diffusion; phosphorus efficiency;

    Abstract : Using more phosphorus fertilizer than needed generates unnecessary costs for farmers and can lead to eutrophication of surface waters. Up to now, most country-specific soil tests to determine P plant-availability use chemical extractions that often extract P from non-plant available pools and are not suitable for all soil types.
