Resumen
[EN] Liming is a common practice used to improve acidic soil properties, as is essential for
agricultural quality. A long-term field experiment with one lime rate (6000 kg/ha of carbonate
calcium equivalent) and three calcium-based liming amendments (gypsum, limestone and sugar
foam) was maintained on a Typic Palexerult for 10 years in order to determine changes in soil acidity
and to assess the effects on crop (rye) yields. The soil acidity conditions decreased with all the
amendments tested, but the sugar foam and limestone was more effective than gypsum over a
long-term period. No significant changes in organic soil matter levels between the treatments tested
were found. Interestingly, an increase in the leaching of organic soil matter was observed in limed
soils. Lime application significantly increased the total rye biomass compared to the control soils
during the whole experiment (2002–2011). Yield trends observed in spike and stem biomass were
similar to those reported for total rye biomass. In this respect, at the end of the research, gypsum,
limestone and sugar foam increased in relation to the total production of rye biomass by 16%, 32%
and 38%, respectively, as compared to the control soils. Additionally, a significant and prolonged
difference in calcium concentrations in rye stems between unlimed and limed subplots was observed.
However, in spite of the results presented here, further investigations are needed to gain a better
understanding of the long-term effects of liming on the chemical properties of soil.
