    Agrifood solutions to climate change
    FAO's work to tackle the climate crisis
    2023
    Amid a worsening climate crisis and slow progress in cutting greenhouse gases, sustainable agrifood systems practices can help countries and communities to adapt, build resilience and mitigate emissions, ensuring food security and nutrition for a growing global population. FAO is working with countries and partners from government to community level to simultaneously address the challenges of food security, climate change and biodiversity loss.But none of this will ultimately succeed unless the world commits to a significant increase in the quality and quantity of climate finance.

    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 nitrogen - Kjeldahl method 2021
    Also available in:
    No results found.

    This standard operating procedure (SOP) describes, in general terms, the quantification of the Kjeldahl nitrogen(KjN) content in soil samples. The advantages of this method are based on its robustness, low initial cost of the equipment and extensive application. However, there are disadvantages in using this method compared to others, for example, the use of potentially hazardous reagents that require consideration for safe operation are utilized, alongside the generation of hazardous waste and on-going cost of consumables, which can be mitigated via modified protocols that use lower quantities of reagents. Another limitation of this method is that it measures organic N and mineral N in the form of ammonium cation (NH4+), therefore, to measure the total N, the mineral N in the form of NO3- must be measured separately
