Abstract: The theoretical aspects, benefits, research contributions, technical recommendations, side effects, limitations, environmental concerns as well as the legislation on the application of phosphogypsum to Brazilian savanna (Cerrado) soils are discussed in this review. It is shown why it is important to apply phosphogypsum to Cerrado soils, and its effect on plant resilience to drought periods. The application of this product may become a main practice in Cerrado soils − a region in which crops as well as pastures are grown − as temperatures rise, and dry periods turn extended, due to climate change. Sulfate, as a component of phosphogypsum, does not leach to groundwater such as in temperate climate soils, turning the use of phosphogypsum environmentally friendly. The phosphogypsum produced in Brazil is a clean by-product of phosphate industry, whose rock source plays an important role providing low trace element and radionuclide contents. It is noteworthy that the Brazilian experience based on phosphogypsum application may work in many tropical soils around the globe, and many populations may be benefited from this technical knowledge |

he use of forage legumes to contribute biologically fixed nitrogen (N) to pastures is an alternative to increase beef cattle production in tropical regions. The objective was to compare the impact of the introduction of a legume with that of N fertilizer application on forage and animal production in Brachiaria pastures. This two-year study assessed three pasture treatments: (1) mixed Marandu palisadegrass (Brachiaria brizantha [syn. Urochloa brizantha] cv. Marandu) and the legume ?ovalifolium? (Desmodium ovalifolium) cv. Itabela (Mixed), (2) Marandu palisadegrass pastures with 150 kg N ha−1 (Fertilized), and (3) Marandu palisadegrass without N fertilizer (Unfertilized). Rotational stocking with a variable stocking rate was used with a target herbage allowance of 1.0 kg forage kg body weight−1. The pre-grazing green herbage mass was similar for Fertilized and Mixed pastures, with 54% and 63% more mass than Unfertilized pasture, respectively (p < .001). Cattle that grazed the fertilized pasture had the greatest average daily gain (ADG; p = .017). The stocking rate and liveweight gain per area were greatest for the Fertilized and Mixed pastures (p < .001 and p < .001, respectively). No differences between treatments were found for DM forage intake (p = .555). Organic matter digestibility was lowest (p < .001) for the Mixed pasture. The inclusion of the ovalifolium legume in the Marandu pasture had the same impact on beef cattle production as annual fertilization with 150 kg N ha−1. The potential and environmental benefits of ovalifolium are discussed.
