【 摘 要 】

For 10 years (1999–2008) there was investigated the effect of liming on soil pHKCl and on organic carbon, available forms of macroelements and DTPA-extracted forms of some metals in 6 different fertilization objects in a long-term experiment set up in 1948: without fertilization (0), straw + NPK (STR NPK), NPK, farmyard manure (FYM), FYM NPK, FYM NPKMgCa. As a result of the application of 12.0 t/ha of lime (4.3 t Ca/ha), an increase was found not only in soil pH value but also in organic carbon, plant available phosphorus, zinc and copper contents and a decrease in manganese content. Despite significant changes in the soil properties, they still varied across the long-term fertilization objects.
