Effects of steel slag-based fertilizers on the endurance to hydric stress of the Brachiaria brizantha.
The necessity to increase the production of food, fibers, agroenergy and other farming products to serve the growing world population stimulates the efficient use of corrective treatments and fertilizers and the search for alternative solutions, as, for instance, the use of steel slag. The use of slag-based products in soil becomes an important resource for the decreasing of environmental impacts caused by storage and the final disposition of its raw material, which also converts into a viable source of income for the steel industry. Another factor of important vegetal production is the use of water, which has a fundamental role in the development of plants, that comes from being the main carrier of soil nutrients, aside from participating in a myriad of physiological functions. Thus, a scenario of hydric restriction causes plant stress and turns into one of the prime reducers of agricultural productivity. In light of the above, this paper had as its purpose evaluating the influence of the application of calcium silicate and magnesium, derived from steel industry residue, over the resistance to the hydric stress of the Brachiaria brizantha cv. Marandu forage, in accordance with the hydric provision available for this culture. The experiment was conducted in a greenhouse following a split plot design, with each plot carrying silicate and the subplots the water blades assessed (100%, 80%, 60%, 40% and 20% of the Field Capacity - FC), in an entire randomized design with four repetitions.
