“…No Brasil, vem crescendo significativamente nos últimos anos o interesse por pesquisas que tratam da utilização de escórias (FORTES et al, 2008). Nesse sentido, o emprego de escórias industriais na agricultura tem sido estudado por alguns autores, que têm confirmado a sua viabilidade para diferentes culturas, como Paparotte e Maciel (2006), Prado e Natale (2004), Oliveira et al (2010), Stocco et al (2010).…”

Influência da aplicação de dois resíduos industriais nas propriedades químicas de dois solos cultivados com café arábica Abstract -The large amount of industrial waste which currently causes serious environmental problems has demonstrated the need for the appropriate use of those materials which not only reduce environmental impact but have shown potential for agricultural use. The aim of this study was to evaluate the chemical effects of different amounts of slag and magnesium oxide on two soils planted with coffea arabica. The study was carried out using pots of 10 dm 3 in a greenhouse at the Center for Agrarian Sciences of the Federal University of Espirito Santo. The experimental design was of randomized blocks with a factorial distribution of 2 x 3 x 6, and three replications, the factors being: two soils (dystrophic red-yellow clay loam and dystrophic red-yellow medium-texture loam), three additives (limestone as control and slag and magnesium oxide as waste), six amounts of corrective materials (0; 25; 50; 75; 100 and 125% of the required liming). After 180 days of culture, analysis of pH, H + + Al 3+ , Al 3+, Ca 2+ e Mg 2+ was carried out. The results showed that applications of increasing doses of magnesium oxide and slag, up to the limit of this study, further a decrease in soil acidity. Magnesium oxide has shown the greatest potential for soil-acidity correction and also as a source of magnesium for the soil.

“…Lower DM production by ruzigrass than by palisade grass has been reported previously (Momesso et al., 2019; Momesso et al., 2020) and may reflect the tolerance of guineagrass and palisade grass to poor soils. Studies have shown that palisade grass has a higher tolerance to acid soil and high soil levels of aluminum, higher biomass yield (Fortes et al., 2008; Timossi et al., 2007), and a higher capacity of regrowth and straw persistence than ruzigrass (Felismino et al., 2012). Palisade grass could feasibly be used in intercropping because of its phenotypic plasticity and shade tolerance, which allow it to grow under limited light (Dias‐Filho, 2002).…”

Integrated crop–livestock systems that intercrop forage crops with grain crops are effective for increasing forage production and improving nutrient cycling and soil health. However, the potential for root competition when maize (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] are intercropped with forages in sandy soils is unknown. The objectives of this study were (a) to evaluate the root growth and production characteristics of maize and sorghum intercropped with forage grasses and (b) quantify above‐ and belowground biomass in a tropical integrated cropping system. Two 3‐yr experiments were conducted in which maize and sorghum were intercropped with forage grasses: guineagrass (Panicum maximum Jacq.), ruzigrass [Urochloa ruziziensis (Germ. & Evrard) Crins], palisade grass [Urochloa brizantha (Hochst ex A. Rich.) R. Webster], or an Urochloa hybrid. Monocropped maize and sorghum were used as controls. Fine roots (≤3 mm) were sampled in the monocropped and intercropped systems at soil depths of 1.0 m. Intercropping guineagrass and palisade grass with maize and sorghum resulted in 40% greater dry matter production than intercropping with ruzigrass and the Urochloa hybrid. The positive effect of intercropping forage grasses in the low‐fertility sandy soil was greater for sorghum than for maize because of lower root growth competition. On average, intercropping maize and sorghum with forages increased the total above‐ and belowground biomass by 30 and 50%, respectively, compared with monocropping. In summary, intercropping maize and sorghum with forage grasses is a viable option to enhance biomass during the off‐season in tropical integrated crop–livestock systems.

“…It is also a nutrient considered beneficial for plants that accumulate this element, such as tropical grasses (Fortes et al, 2008). Concomitantly with the good practices of implantation of the culture, it appears that new technologies are being explored in order to improve the quality of the pastures, as is the case of vitamins.…”
