“…Furthermore, in the MT experiment, the L2.5 + G2.5 treatment resulted in a 54-84% reduction in soil Al CaCl 2 in the soil layers 20-50 cm (Figure 2e) and no effect subsoil pH CaCl 2 (Figure 2h). These observations are consistent with other experiments that observed the application of L decreased Al Ex to a greater depth than the decrease in pH CaCl 2 [38][39][40]. For example, in an experiment monitored over time, application of 6 t L ha −1 increased pH CaCl 2 in the 10-20 cm soil layer by 0.2-0.4 pH units after 2.5 years with the effect remaining constant over time while Al Ex decrease by 55% after 2.5 years and to 68% after ten years [41].…”

Soil acidity or aluminum (Al) toxicity is a major limitation to crop production. In this paper, we examine the effects of surface-applied lime and gypsum on soil profile chemical properties that affect Al toxicity in short-term (1 year), medium-term (2 years and 8 months) and long-term (10 years) experiments. Sulfate applied to the soil surface as gypsum was leached rapidly to a depth of 40 cm in the short-term despite relatively low amounts (279 mm) of rainfall. In the medium and long-term experiments, 28–54% of the sulfate applied as gypsum was retained in the 0–50 cm soil layer due to adsorption and precipitation reactions. The combined application of lime and gypsum increased soil calcium, to a depth of 30 cm in the short-term and to a depth of 50 cm in the medium and long-terms. Increases in soil sulfate and calcium were associated with greater electrical conductivity to a depth of 50 cm for all sampling times. Application of lime alone had no impact on soil Al, pH, and calcium in the soil layers below 10 cm in the short and medium terms. In the long-term, increasing the rate of lime application from 2 to 8 t L ha−1 increased soil pH in the 10–20 cm soil layer while soil Al decreased to a depth of 30 cm. The combined use of lime and gypsum decreased soil Al in the 30–50 cm soil layer in the medium-term and the 20–30 cm soil layer in the long-term which was more than when only lime was applied. Hence, we recommend the use of lime plus gypsum for treating soils with subsoil Al toxicity. Additionally, soil Al measurements are a more sensitive measurement of the impact of surface application lime and lime plus gypsum than soil pH.

“…In others soils, as the Haplic Umbisol, the reaction of DL (878 g kg -1 of ECC) with fineness particle (< 0.25 μm) was much faster than with DL of coarsest particle (2-4 mm), during 36 months and 0-20 cm layer [1]. Already, the absence of liming material effect in 5-60 cm layer can be attributed the following factors that (i) the soil presented higher potential acidity [22], (ii) the dissolution/dissociation as far from acidity zone and reaction time [26]; (ii) subsoil pH is adequate [12], (iii) the neutralization of aluminum (Al 3+ ) and of hydrogen (H + ) on soil functional groups is limited [26], (iv) the soil buffering power is strongly by Al and iron (Fe) oxides [8], (v) lower water infiltration via macroporos [2] and (vi) lower adsorption/desorption of cations by organic anions soluble [17].…”

“…O favorecimento da calagem às plantas enaltece a importância da correção da acidez do solo para que a cultura possa expressar seu máximo potencial produtivo (RUTKOWSKA et al, 2015) e, consequentemente, garantir maior retorno econômico ao agricultor. O calcário é o principal corretivo usado para correção do pH do solo e sua efetividade é bem fundamentada na literatura para solos do sul do Brasil, havendo uma série de estudos voltados à eficiência e custo/benefício de seu uso em relação a outras alternativas no mercado (MIOTTO et al, 2020;PÖTTKER;BEN, 1998;VARGAS et al, 2019).…”

A calibração da necessidade de calagem para um solo é de fundamental importância para a correção efetiva da acidez além de assegurar o bom desenvolvimento das culturas agrícolas. Diante disso, o objetivo do trabalho foi estabelecer a dose de corretivo de acidez mais adequada para o desenvolvimento da cultura da soja. O trabalho foi realizado em casa-de-vegetação, utilizando um Cambissolo Háplico. Os tratamentos consistiram na incorporação de CaCO3 na quantidade equivalente para elevar o pH a 6,0 e frações desta dose. Após o período de incubação determinou-se o pH do solo e posteriormente foi realizada a semeadura da soja. O pH-H2O e a acidez potencial (H+Al) variaram de 4,0 a 6,8 e 15,6 a 1,3 cmolc dm-3 entre a menor e maior dose de corretivo, respectivamente. O incremento de massa seca da parte aérea foi proporcional a quantidade de corretivo, com produtividade máxima para a dose de 110% do preconizado, com posterior declínio. O número de vagens e a massa seca das raízes também foram positivamente influenciados pelo aumento da dose. Com base na correlação entre os componentes do solo e da planta, a quantidade de CaCO3 recomendada para a cultura da soja neste solo é de 10 Mg ha-1.
