The incorporation of new sources of fertilizers is important to of the food production security. The use of rock powders still needs investigation to address their agronomic efficiency and the safety for the users and for the consumers. This work aimed to study the dry matter production and the nutrient extraction after three consecutive crops, in two soils fertilized with serpentinite rock powder. The experiment was carried in a greenhouse, with three sequential crops, with seven treatments, two soils and four replications. After 40 days of growth, the whole plants were harvested and sent to measure the dry weight and for the chemical analyses. The use of the serpentinite did not increase the total dry matter biomass weight, compared to the fertilized controls. The magnesium extraction was not different between the control treatment with dolomitic limestone and the serpentinite treatment at higher dose for the clayed soil, indicating that the serpentinite was able to supply the magnesium for the plants in the experimental condition, and also a significant dose related effect suggests that the magnesium from the powder has been released. The use of the serpentinite also increased the extraction of other nutrients, like calcium, phosphorus, zinc and iron. |

Some regions of the Cerrado Biome present edaphoclimatic conditions restrictive to the maximum productive potential of agriculture and livestock. In these regions, experiments with crop-livestock system (CLS) show that this strategy allows the intensification of agricultural production in a sustainable manner. Rotation, intercropping and succession of crops producing grains or silage with forage species, and conservationist soil management such as no-till and correction of the soil profile favorable to root growth, allow the exploitation of the agricultural area, especially when there is a water deficit. In fifteen years of conducting the CLS, the production of agricultural crops met the demand for food and, also, provided grain yields above regional averages, and even national averages. In addition to the lower risk, the strategy adopted met internal demand and generated surplus grain and silage for commercialization, increasing income. In the temporal analysis of the CLS, the adoption of sustainable soil and crop management practices has, over time, overcome the region's edaphoclimatic limitations, in an economically viable way, based on adequate land use planning, and by the choice of appropriate combination of crops, properly aligned with the livestock activity of interest. |
