Resumo
This research assessed the effect of calcium silicate
application to soil surface on dry matter production and Si
concentration on grass shoots, as well as chemical characteristics
of a soil under degraded forage grass pasture. The experiment
was carried out in a greenhouse, using a completely randomized
design, in a 5x2 factorial arrangement, with four replicates.
Treatments consisted of five calcium silicate doses (0 kg ha-1;
500 kg ha-1; 1,000 kg ha-1; 1,500 kg ha-1; and 2,000 kg ha-1)
and two forage grasses (Brachiaria brizantha cv. Marandu and
Panicum maximum cv. Mombaça). Shoot cuttings were performed
at 45 and 95 days after sowing. Shoot dry mass accumulation and
absorbed Si foliar concentrations were quantified, besides soil pH,
Ca, P, Al, and V values, after grass harvesting. Calcium silicate
application induced higher absorption of Si in Marandu, as well
as in Mombaça. Marandu cultivar dry mass accumulation did not
differ from Mombaça. Calcium silicate application increased pH
and soil base saturation decreased the aluminum level.
