    Standard operating procedure for soil available phosphorus - Olsen method 2021
    Also available in:
    No results found.

    This procedure is suitable for calcareous, alkaline, neutral, and slightly acidic soils containing CaPO4, since the calcium concentration in the solution is suppressed by the precipitation of CaCO3, increasing PO4 concentration in solution. Neutral and slightly acid soils (pH 6.0 to 7.0) may contain both Ca- and Al-phosphates. The NaHCO3 extractant can remove Ca-phosphates and phosphate adsorbed on the surface of calcium and magnesium carbonates along with Al-phosphates and is considered the most suitable extractant for these soils.

    Standard operating procedure for soil available phosphorus - Bray I and Bray II method 2021
    Also available in:
    No results found.

    P-Bray 1 and P-Bray 2 methods are normally limited to acid soils with water pH values less than 6.8. The P-Bray 1 Method removes a fraction of the “adsorbed” phosphorus (Al-P, Fe-P, Mn-P and Ca-P but less efficient) while the P-Bray 2 Method is best suited to acid soils where rock phosphate has been the primary P fertilizer source and/or the major portion of P exists in the soil in various forms of calcium phosphate. Bray extractants should not be used on alkaline soils because the acid tends to be neutralized and/or excessive calcium phosphates may be extracted, giving a false high test for available P.

    Post-harvest management of banana for quality and safety assurance
    Guidance for horticultural supply chain stakeholders
    2018
    Also available in:
    No results found.

    This guidance note presents the results and lessons learned from an FAO Technical Cooperation Project for capacity development to reduce post-harvest losses in horticultural chains in Timor-Leste. Technical improvements were piloted in Timor-Leste with stakeholders in traditional banana supply chains.
