Some basic soil fertility parameters have been monitored in the Czech Republic since 1961, at intervals of three to six years, as a part of the national agrochemical soil testing programme. This mandatory programme governs the wording of later regulations on fertilisers and covers in particular the determination of soil reaction and content of available nutrients (P, K, Mg and Ca). In specific cases (e.g. application of sewage sludge to soil, soil testing in organic farming, soil damage caused by flooding, etc.), soil physical and microbiological parameters are also measured. The results for the past 20 years (1989–2008) show a decreasing tendency in pH value and content of available nutrients in agricultural soils. The land parcel identification system (LPIS) is used for testing, and all sampling areas are fixed in the national mapping system (S-JTSK). All the results are available to farmers and government bodies.
