“…According to Korndorfer and Nolla (2003), hydrolysis of the silicate anion present in the serpentinite occurs the release of hydroxyls (OH -), which reacts and neutralizes the H + in solution, raising the pH and precipitating Al 3+ in the form of Al hydroxide [Al(OH) 3 )], low solubility and inactive in soil solution and therefore non-toxic to plants. The reduction of soil acidity with the use of silicates was also observed by other authors such as Alovisi et al (2018), and Moraes et al (2018).…”

The serpentinite is an alternative for the correction of soil acidity and is composed of calcium and magnesium silicate. The objective of this study was to evaluate the residual effect of the serpentinite application on soil chemical attributes and the effects on wheat crop productivity in a no-tillage system. The experimental design was a randomized block design, in a subdivided plot scheme, with four replications. The plots were constituted by serpentinite doses (0, 2, 4, 8 and 16 Mg ha-1) and in the subplots the soil collection layers (0.0-0.10 and 0.10-0.20 m). The chemical attributes of the soil evaluated at 41 months after the application of serpentinite, presented favorable results of the residual power of this corrective. The main results observed are related to the increase of pH, decrease of aluminum content and potential acidity, and increase of Ca, Mg and Si contents, cation exchange capacity (CTC) and base saturation. The residual of the serpentinite in the soil contributed with an improvement in the chemical attributes of the soil, which favored the increase of the dry mass, number of spikes and yield of the wheat crop.

A reação do calcário limita-se ao local de sua aplicação no solo, havendo dúvidas sobre sua eficiência em reduzir a acidez em profundidade quando aplicado superficialmente sem incorporação. Portanto, o objetivo deste trabalho foi analisar o movimento e resíduo de diferentes doses de calcário no perfil do solo e sua influência na produtividade de grãos de soja. O delineamento experimental utilizado foi em blocos casualizados com seis tratamentos e quatro repetições. O calcário foi aplicado manualmente por lanço, sem incorporação. Um mês após o plantio da soja, estimou-se o rendimento de cada tratamento. Após a colheita, a amostragem do solo foi realizada em três profundidades para análises químicas. No ano seguinte, o plantio da soja e as mesmas avaliações foram realizadas. Os dados obtidos foram submetidos à análise de variância e, quando significativos, as médias foram comparadas pelo teste de Tukey. Houve efeito residual, movimentação e melhor eficiência do calcário no perfil do solo a partir da aplicação da dose recomendada. A produtividade dos grãos aumentou à medida que os percentuais da dose recomendada de calcário aumentaram na primeira safra, na safra seguinte apresentou melhor produtividade na dose recomendada.

“…Although limestone is the most used soil-acidity corrective, other materials, such as steel slag (silicate), have been tested as corrective agents and shown efficient results. The application of silicate provides positive effects on the chemical attributes of the soil related to acidity correction, e.g., pH, Ca and Mg contents, CEC and SB (Alovisi et al, 2018), besides increasing the availability of P in the soil when compared with limestone (Souza and Chaves, 2015).…”

Soil correction for planting bermudagrass using steel slag or limestone

et al. 2020

Limestone is the most commonly used acidity-correction agent in tropical soils. However, steel slag can be an alternative for turfgrass production areas because it contains silicon, which can increase turfgrass tolerance to biotic and/or abiotic stresses. This study was developed to evaluate the effect of the application of steel slag, as compared with limestone, on a bermudagrass sod production system. The experiment was carried out in Botucatu-SP, Brazil, in a randomized block design arranged in a factorial scheme 2 × 5 with 4 replications. Treatments consisted of two correctives (steel slag and limestone) and their rates, which were calculated to raise the soil base saturation to 12% (current), 30%, 50%, 70% and 90%. The application of lime and steel slag rates had positive effects on soil chemical attributes related to acidity correction, such as pH, Ca, Mg, H + Al, Al, CEC, SB, and base saturation (%). The slag provided higher levels of P, Ca, and Si, whereas limestone increased the Mg soil content. Steel slag provided a higher ground cover rate for bermudagrass than limestone at 114 and 161 days after transplanting (DAT), with maximum cover rate achieved with 60% base saturation at 161 DAT. The turfgrasses treated with slag showed a higher amount of roots, rhizomes, and stolons when compared with those treated with limestone. It is suggested the use of steel slag and, in calculating the need for corrective, 90% soil base saturation.
