Long-Term Soil Ecosystem Studies

TEMS - terrestrial ecosystem monitoring sites

The International Union of Soil Sciences (IUSS) is the global union of soil scientists. The objectives of the IUSS are to foster all branches of the soil sciences and their applications, and to give support to soil scientists in the pursuit of their activities. This website provides information for IUSS members and those interested in soil science.

At Earth’s surface, a complex suite of chemical, biological, and physical processes combines to produce soil from bedrock and sediments within the zone that extends from the outer limits of vegetation to the lower limits of groundwater. This weathering engine transforms primary minerals, provides nutrients to nourish ecosystems and human society, mediates the transport of toxic components within the biosphere, creates water flow paths that shape and weaken bedrock, and contributes to the evolution of landscapes at all temporal and spatial scales. At the longest time scales, the weathering engine sequesters CO2, thereby influencing the global carbon cycle, long-term climate change, and weathering rates.

Rothamsted is the largest agricultural research centre in the United Kingdom and almost certainly the oldest agricultural research station in the world.

The Frozen Ground Data Center has now published the content of CAPS on this web site and continues to expand and improve access to frozen ground data.

The Integrated Plant Nutrition Information System, referred to as IPNIS, is a database providing information for a number of countries on crop-wise plant nutrients management at administrative (district) level, supported by relevant data on soil and soil management, agro-ecological zones, and crop production constraints.

The FAO Fertilizer Programme carried out trials and demonstrations on crops in farmer's fields from the 1970's through the 1990s in 32 nations. Results are presented on this website.
