The aim of this study was to evaluate the tolerance of sunflower (Helianthus annuus) to acetolactate synthase (ALS)-inhibiting herbicides and to temporarily delay the growth of Brachiaria ruziziensis, avoiding competition and allowing pasture reestablishment. Experiment 1 consisted of a randomized complete block design, with four replicates. Hybrid Paraiso 102 CL (Clearfield®, resistant to ALS-inhibiting herbicides) was a subject of the following treatments: I) 30 g ai ha-1 imazethapyr; II) 70 g ai ha-1 imazethapyr; III) 75 g ai ha-1 imazapyr; IV) 125 g ai ha-1 imazapyr; V) 7.5 g ai ha-1 chlorimuron-ethyl; VI) 12.5 g ai ha-1 chlorimuron-ethyl; VII) 8 g ai ha-1 nicosulfuron; VIII) 20 g ai ha-1 nicosulfuron; IX) unhoed check and X) hoed check. Experiment 2 consisted of a split-plot design with randomized complete blocks and four replicates. Two genotypes, Paraiso 102 CL and Embrapa 122 (susceptible to ALS-inhibiting herbicides), were sowed on the plots and subplots were submitted to the following treatments: I) hoed check, II) unhoed check, III) 100 g ai ha-1 imazethapyr, IV) 250 g ai ha-1 imazapyr, V) 25 g ai ha-1 imazapyr, VI) 60 g ai ha-1 nicosulfuron, and VII) 4 g ai ha-1 nicosulfuron. Imazethapyr (30, 70 and 100 g ai ha-1), imazapyr (25, 75 and 125 g ai ha-1) or nicosulfuron (4, 8 and 20 g ai ha-1) had no phytotoxic effects on imidazolinone-resistant sunflower (Paraiso 102 CL). However, chlorimuron-ethyl (7.5 and 12.5 g ai ha-1), imazapyr (250 g ai ha-1) and nicosulfuron (60 g ai ha-1) were highly phytotoxic to Paraiso 102 CL. All herbicide treatments produced marked injury symptoms on Embrapa 122. Pasture reestablishment was observed for all herbicide treatments, except for imazapyr (125 and 250 g ai ha-1) and nicosulfuron (60 g ai ha-1).

Effects of wood ash application on tree nutrition and soil dynamics in a Pinus taeda system. |

Many Brazilian forest industries use wood biomass as a sustainable energy source that generates a wood ash by-product. This residue is typically discarded in nearby planted forests. To evaluate the effects of wood ash rates on Pinus taeda L. growth, a study was established on a high clay soil in 2006. Five rates of wood ash (0, 10, 20, 40, and 80 T ha−1) were applied to a P. taeda system. Soil chemical properties were evaluated three times at different depths. Tree growth (i.e., height, diameter at breast height, and commercial volume) and nutrition (needle elemental composition) were determined. After 11 years, litter accumulation and soil mobilization (bioturbation) were also evaluated. Ash application did not affect tree growth/yield or litter accumulation. A small reduction in soil acidity and increased bases in the upper soil layer were observed two years after ash application; this effect reached deeper layers after six years but retreated to shallower depths at 11 years. A soil amount of 14.6 m3 ha−1 year−1 was relocated closer to the soil surface due to bioturbation by edaphic fauna. The application of wood ash to forest soils appears to be an ecologically sound alternative for disposal of this industrial by-product. |
