Abstract

The objective of this study was to evaluate whether the development of corn (Zea mays) and soil fertility are influenced by the application of increasing doses of calcium silicate (CaSiO3) in substitution to limestone. The experiment was carried out under greenhouse conditions and the experimental design was in randomized blocks, in a 3x2+1 factorial arrangement and four replications. The factors were: doses of CaSiO3 (7.62 mg.dm-3, 19.05 mg.dm-3 and 38.09 mg.dm-3) and liming (absence and presence). The soil of the control treatment did not receive limestone or CaSiO3. At 21 days after emergence (DAE), it was found that the control treatment plants had significantly lower height and stem diameter. At 35 DAE was observed that using exclusively CaSiO3 promoted 6% higher stem height values. At 63 DAE, no oscillations were observed in the biomass of aerial part and root between liming and CaSiO3 doses (P>0.05). Using the limestone allied the silicate doses increased in higher concentration of Mg in the soil. The lowest dose of CaSiO3 reduced the concentrations of Ca and Mg. Calcium silicate can be used as an alternative source to limestone for soil acidity correction.

Highlights

Limestone is a concealer used for centuries to correct soil acidity (Thomason et al, 2019); because it presents slow mobility in the soil profile, it can slow its effect in the deeper layers (Ramos et al, 2006) and decelerate the accumulation of biomass aerial part (Lopes et al, 2011; Fabrice et al, 2014).The use of alternative corrections has been evaluated according to the limitations of limestone

Summary

Introduction

The use of alternative corrections has been evaluated according to the limitations of limestone For this reason, the use of silicate-based products were identified as promising corrective, which could positively impact the production of biomass and grains (Crusciol et al, 2013; Ning et al, 2016). Silicon (Si) is a non-essential nutrient for plants, but it stands out in many cultures such as sugarcane (Oliveira et al, 2010), rice (Hyun-Hwoi et al, 2017) and forage grasses (Silveira et al, 2010; Lopes et al, 2011). This element is associated with the reduction of biotic and abiotic stresses of the Si storage plants, such as diseases (Guazina et al, 2019), pest injuries (Antunes et al, 2010; Zargar et al, 2019), salinity (Zhu et al, 2019), drought (Saud et al, 2014) and heavy metal toxicity (Bhat et al, 2019)
