Influence of Calcium Silicate on Soil Fertility and Corn Morphology

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.

Liming and biochar on sorghum growth and Arenosol chemical properties in the Semiarid environment

“…Lime is one of the most important agricultural inputs and has been widely used to correct surface soil acidity (LoCHoN et al, 2019). Its application increases the soil pH, neutralizes aluminum, and increases macronutrient availability for plants, keeping soil fertility balanced (FERNANDES et al, 2020b). It is also considered a great source of Ca and Mg, promoting favorable conditions for increasing the biological activity of the soil and for the development of the root system of plants (GURGEL et al, 2020).…”

“…Taking into account that liming is essential to increase the yields of agricultural and forage crops (LoCHoN et al, 2019;FERNANDES et al, 2020b) and that biochar offers several agricultural and environmental benefits (KALU et al, 2021;ZEESHAN et al, 2020;SHAKooR et al, 2021). However, there are few reports on the use of liming in association with limestone and biochar in the cultivation of forage sorghum in sandy soils in semi-arid environments.…”

Adubação potássica em cobertura e a associação de nitrogênio com silicato de potássio na morfologia de plantas, incidência de carvão comum e produtividade de grãos de milho

“…Classificado como um elemento útil para as plantas, o silício tem se destacado em diversas culturas agrícolas por trazer inúmeros benefícios às plantas, principalmente nas acumuladoras de Si (Artyszak, 2018). Entre eles, destaca-se o aumento da resistência ao estresse hídrico; maior eficiência fotossintética; redução dos ataques de insetos-praga e doenças e, se aplicado ao solo, melhora seus atributos químicos (Korndörfer et al, 2010;Sakr, 2017;Fernandes et al, 2020;Guazina et al, 2020). Sabendo que fontes de Si (e.g., silicato de potássio [K2SiO3]) podem reduzir o efeito negativo de estresses abióticos e bióticos e, ao mesmo tempo, promover aumentos na produção de grãos nas culturas agrícolas (Soratto et al, 2012;Moise et al, 2019), é possível deduzir que a associação K2SiO3 com o N pode melhorar o desempenho das plantas de milho.…”

Agronomic and Economic Evaluation of Sequential Spray of Silicon and Fungicides for a Sustainable Soybean Crop

“…Studies about the mineral nutrition of soybean are of paramount importance to minimize factors that might reduce its yield, especially those related to losses caused by Asian rust (Sousa et al, 2019). Among the useful elements, silicon stands out for providing benefits in soil chemical attributes (Fernandes et al, 2020), the development of healthier plants (Rasoolizadeh et al, 2018) and resistance to abiotic stress (Zargar et al, 2019) and acting on important epidemiological components of diseases (Guerriero et al, 2016). The disease resistance provided by silicon is related to the induction of physical and chemical barriers such as cell wall lignification and production of organic compounds and defense enzymes, which hinder the penetration and colonization of the pathogen on the host plant (Guerriero et al, 2016).…”
