Brochure, flyer, fact-sheetBrochureStandard operating procedure for soil calcium carbonate equivalent - volumetric calcimeter method 2020
Also available in:
GLOSOLAN is a Global Soil Laboratory Network which aims to harmonize soil analysis methods and data so that soil information is comparable and interpretable across laboratories, countries and regions. Evidence-based decisions are critical to the achievement of Sustainable Soil Management (SSM), food security and nutrition, and Agenda 2030 for Sustainable Development. While the quantity and quality of soil data are fundamental, soil information must also be harmonized and globally consistent to have impact. Standard operating procedures (SOPs) are sets of step-by-step written instructions that help lab staff to carry out routine operations by describing, in detail, how to perform a laboratory process or experiment safely and effectively. SOPs aim to achieve efficiency, quality of output and uniformity of performance, while reducing miscommunication and failure to comply with laboratory and international standards. The harmonization of laboratory standard operating procedures and methods is at the basis of harmonizing soil laboratory data. -
BookletCorporate general interestStandard operating procedure for soil microbial biomass (carbon): chloroform fumigation-extraction method 2024
Also available in:
No results found.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. -
Brochure, flyer, fact-sheetBrochureStandard operating procedure for soil moisture content by gravimetric method 2023
Also available in:
No results found.Soil moisture content is one of the fundamental properties used in making decisions related to soil management, such as land preparation, design of irrigation and drainage systems, construction, and risk management. Analytically, determination of air-dry moisture content (i.e. remaining moisture in soil, dried for laboratory analysis) is important, since it is used to express the results of other tests (e.g. carbon, nitrogen, phosphorus, etc.) on an oven-dry basis. Soil moisture content analyzed by the gravimetric method has low operational difficulty and can be used for multiple purposes.

BookletHigh-profileFAO Strategy on Climate Change 2022–2031 2022The FAO Strategy on Climate Change 2022–2031 was endorsed by FAO Council in June 2022. This new strategy replaces the previous strategy from 2017 to better FAO's climate action with the Strategic Framework 2022-2031, and other FAO strategies that have been developed since then. The Strategy was elaborated following an inclusive process of consultation with FAO Members, FAO staff from headquarters and decentralized offices, as well as external partners. It articulates FAO's vision for agrifood systems by 2050, around three main pillars of action: at global and regional level, at country level, and at local level. The Strategy also encourages key guiding principles for action, such as science and innovation, inclusiveness, partnerships, and access to finance.

BookletCorporate general interestEmissions due to agriculture
Global, regional and country trends 2000–2018
2021Also available in:
No results found.The FAOSTAT emissions database is composed of several data domains covering the categories of the IPCC Agriculture, Forestry and Other Land Use (AFOLU) sector of the national GHG inventory. Energy use in agriculture is additionally included as relevant to emissions from agriculture as an economic production sector under the ISIC A statistical classification, though recognizing that, in terms of IPCC, they are instead part of the Energy sector of the national GHG inventory. FAO emissions estimates are available over the period 1961–2018 for agriculture production processes from crop and livestock activities. Land use emissions and removals are generally available only for the period 1990–2019. This analytical brief focuses on overall trends over the period 2000–2018.
