Abstract: Increasing N use efficiency is an important strategy to intensify sustainable agriculture, optimize nutrient use, and reduce N loss to the environment via different routes. Owing to its physicochemical properties, biochar can be used as an additive to produce biochar-based fertilizers (BFs) with increased efficiency. We investigated N availability and ammonia loss from 17 BFs (3%?38% N). N availability and release from BFs were evaluated by water extraction experiments and soil column leaching. BFs (5%?10% N) had an average of 64% solubilized N after five extractions, whereas urea had 98% solubilized N. However, BFs produced with urea released N more slowly in soil, with the release rate 60% less than that of urea. Ammonia volatilization was evaluated using a 22-d experiment, where N was applied to soil surface (pH = 4.4). We compared urea, BF granulated with urea, and BF produced by coating urea granules with acidified or unacidified biochar. Compared to urea, biochar-based fertilizers granulated with urea and urea granules coated with acidified biochar significantly reduced (t-test at 5%) ammonia volatilization by 14%. The results demonstrated the potential of BFs as enhanced efficiency fertilizers. Therefore, BFs might be a good option to mitigate N loss. |

Elephant grass is a forage plant widely spread in Brazil that was initially employed exclusively in the livestock sector as feed for cattle. This grass is characterized by its high productivity and high photosynthetic capacity. In addition to being used as forage, it has shown to be an alternative source of renewable energy. The objectives of the present study were to evaluate the morpho-agronomic traits of elephant grass hybrids and their parents for biomass energy production. The experiment was conducted in a randomized-block design with three replicates. The partial diallel was composed of 16 hybrids and two groups (males and females). Data were subjected to analysis of variance and the Tukey?s mean comparison test (P < 0.05). Interaction was detected by the F test for the traits dry matter yield, plant height, and leaf width. Based on the mean values, hybrids H11 and H14 seem to be promising for dry matter production for energy purposes. Parent Porto Rico 534-B can be indicated in breeding programs. |
