Synopsis (short abstract) The method provides a potential indicator of the plant available copper, iron, manganese and zinc, which are essential soil micronutrients for plant growth and living organisms. It can be used to extract heavy metals such as nickel, lead and cadmium assisting with conclusions as to their potential bioavailability. This method must be used in combination with suitable determination methods, for example, flame atomic absorption spectrometry, electrothermal atomic absorption spectrometry or inductively coupled plasma – optical emission spectrometry.

    Standard operating procedure for soil microbial biomass (carbon): chloroform fumigation-extraction method 2024

    Microbial biomass is considered as an estimation of soil biological activities and the capacity to mediate soil biochemical reactions. It is the most dynamic and labile of soil organic matter fractions, generally accounting for 1 to 5 percent of soil organic matter and very sensitive to soil management. The need to quantify soil microbiota has become increasingly relevant in current times as they are responsible for many different processes like the degradation of organic matter, the stability of aggregates and most of the nutrient cycling that occurs in soils. This standard operating procedure (SOP) focuses on the determination of soil microbial biomass using the chloroform fumigation-extraction method, which is applicable to both aerobic and anaerobic conditions over the whole range of soil pH, regardless of land use type. While chloroform fumigation also affects soil fauna, the carbon aliquot derived from these organisms is generally small (less than 5 percent) and can usually be disregarded.

    Standard operating procedure for heavy metal determination in phosphate fertilizer materials 2024
    Also available in:
    No results found.
    The International Network on Soil Pollution (INSOP) and the International Network on Soil Fertility and Fertilizers (INSOILFER) harmonize standard operating procedures (SOPs) for determining the analysis of fertilizers and make them available online – to all users for free. SOPs offer step-by-step instructions on how to perform laboratory analyses. SOPs are a critical component in ensuring the quality, safety and replicability of measurements and the credibility and traceability of data. The globally harmonized protocol for detecting heavy metals in fertilizers was developed with the assistance of 85 laboratories from 60 countries. Its aim is to facilitate the quality and safety analysis of heavy metals in fertilizers.
