Yield and mineral nutrition of soybean, maize, and Congo signal grass as affected by limestone and slag

Abstract: -The objective of this work was to evaluate the efficiency of superficial application of limestone and slag, and their effects on soil chemical attributes and on yield and mineral nutrition of soybean, maize, and Congo signal grass (Urochloa ruziziensis). The experiment was carried out in a Rhodic Hapludox under no tillage system. The treatments consisted of the use of limestone or slag (silicates of calcium and magnesium) to correct soil acidity, and of a control treatment without the use of soil correctives.… Show more

“…These results corroborate those obtained by Castro & Crusciol (2013a, 2013b for several crops. These results had a direct effect on potassium uptake by soybean and sorghum, which shows an antagonist effect between the nutrients, as they compete for the same uptake sites.…”

“…In their tillage experiment in which stainless steel slag and limestone were applied on the soil surface with a clayey texture to raise base saturation at 70% before the succession culture of soybean, Congo signal grass and corn, Castro and Crusciol (2013) failed to report variations in leaf rates of N, K and S of soybean and of P, K and S of corn when correctives were applied. However, the authors registered increase in P concentrations of soybean leaves, N concentrations in corn leaves and in Ca, Mg and silicon concentrations in the two crops when acidity correctives were applied.…”

“…These material contain silicon whose effects have been the object of several assays in rice (Artigiani et al, 2014), potato (Pultz et al, 2008), tomato (Marodin et al, 2014), bean (Deus and Büll, 2013), soy and corn (Castro and Crusciol, 2013) and sugarcane (Reis et al, 2013). However, the use of steel slag in agriculture is still rare in Brazil.…”
