Effect of liming on the change of some agrochemical soil properties in a long-term fertilization experiment

Abstract

For 10 years (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008) there was investigated the effect of liming on soil pH KCl and on organic carbon, available forms of macroelements and DTPA-extracted forms of some metals in 6 different fertilization objects in a longterm 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 longterm fertilization objects.

“…Regular application of lime and FYM resulted in build of phosphorus and potassium. The present results corroborated the findings of Jaskulska et al, (2014). The secondary nutrients statues in soil found to increase in all the treatments over the initial values, however application of balanced fertilizers resulted in higher buildup in soil compared to absolute control and inorganics alone.…”

The changes of soil acidity in long-term fertilizer experiments

“…The results in other long-term experiments show that only a long-term regular combined application of organic (Repšienė, Skuodienė, 2010) and mineral fertilizers together with liming once in crop rotation made it possible to maintain the soil pH value at initial level. The regular application of lime resulted in a successive, 1999 through 2008, increase in soil pH value in all fertilization treatments by 1.7-2.7 units (Jaskulska et al, 2014). Changes in the periodically limed soil pH, hydrolytic acidity and mobile Al were more intense and their restoration to previous levels is slower compared to primary limed soils.…”

Some Aspects of Soil Acidification in Poland Based on Łódź Province

“…The observed difference has important implications since it is usually assumed that an average of 60-110 kg CaCO 3 should be introduced to soil per every 100 kg of nitrogen fertilizer (ammonium sulfate, urea, ammonium nitrate, and derivatives) to decrease soil acidity [20]. Soil acidifi cation is an issue with environmental and social implications, and liming treatments are needed to improve crop quality and prevent further degradation of the soil environment [21,22].…”
