Brochure, flyer, fact-sheetStandard operating procedure for handling and preparation of soil samples for chemical and physical analyses 2020GLOSOLAN 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.

Book (stand-alone)A practical manual of soil microbiology laboratory methods 1967
Also available in:
No results found.Soil microbiology is the science that deals with the millions of very small forms of life found in the soil. Agricultural crop production should insure that full use is made of the benefits to be gained from proper management of soil micro-organisms. The methods outlined in this soils bulletin represent various experimental approaches to the more important aspects of the subject matter of soil microbiology. The experimental approaches are simple, selected and designed to demonstrate techniques a nd principles but not advanced research methods. -
Book (stand-alone)Soil survey interpretation and its use 1967
Also available in:
No results found.This soils bulletin brings together some of the methods which have been developed and tested in countries that have active programs of making and using soil surveys, and a summary of some of the principles of soil survey interpretation. It is mainly addressed for the soil scientist who is making and interpreting a soil survey, or who is re-interpreting a soil survey already completed. Methods are suggested, with examples, for comparative ratings of soils, capability grouping of soils for the com mon crops, estimating yields of crops on different kinds of soil under defined sets of other growth factors, groupings of soils for range and for woodland management, and use of soil maps and reports in engineering work that involves soils as foundations or as construction material. There are also brief discussions of soil maps for planning, use of soil maps in appraisal of land, and the preparation and use of general soil maps.
