Grasses Control Strategies in Setting Restoration Stand of the Atlantic Forest

Abstract

This study aimed to assess the effectiveness of four weed control strategies in forest setting stands linked by a set of Atlantic Forest tree species. Four treatments were employed: mechanical -manual hoeing and mowing; chemical -glyphosate herbicide application in the total area; chemical -cultural -herbicide spraying and herbaceous legume intercropping; chemical-mechanical -herbicide planting in rows and mowing in the interrows. Diameter, crown area and soil cover percentage of the eight tree species were assessed at 18 months. Herbicide spraying in total area promoted the greatest reduction in weed populations, as well as superior growth in height, diameter, crown area and soil cover of the tree species. More interventions were necessary in the treatment of mechanical weed control that has also shown the least growth of the tree species. The chemical method was the most effective in weed control and promoted the greatest growth of the tree species.

“…Vale ressaltar que, as gramíneas apresentam grande participação nas mudanças ocasionadas no estoque de C do solo (LAL, 2018). No Sudeste do Brasil, a presença de gramíneas, em especial do gênero Urochloa, são comuns em áreas de reflorestamento, sendo que, grande parte dessas áreas já foram anteriormente utilizadas como pastagem, e possuem alta capacidade de adaptação (SANTANA et al, 2020). A literatura atribui o C acumulado e distribuído nessas áreas florestais, as gramíneas, correspondente a quantidade de biomassa produzida e sistemas radiculares vigorosos com maior taxa de reciclagem (FUJISAKA et al, 1998;DURIGAN et al, 2017).…”
