ResumoCom este trabalho se objetivou argumentar o uso da tecnologia de capina elétrica para dessecação e/ou controle de plantas daninhas no sistema de silvicultura, auxiliando nas medidas para conservações do meio ambiente como alternativa ecológica. A revisão destaca a tecnologia de aplicação atual na silvicultura, os principais métodos de combate às plantas daninhas, até chegar ao funcionamento da capina elétrica. Foram relatadas as principais características, funcionamento e algumas hipóteses para inserção ou não do equipamento para a silvicultura. A atividade da capina elétrica na silvicultura em determinada região e época do ano é inviável em relação a critérios técnicos e ecológicos, devido aos riscos de incêndios quando se tem muita matéria seca sobre o solo.Palavras-chave: ambiente, sustentabilidade, tecnologia. ALTERNATIVE FOR WEED CONTROL BY ELECTRIC WEDDING IN FORESTRY SYSTEMS AbstractThe aim of this study was to argue the use of electric weeding technology for desiccation and/or weed control in the forestry system, aiding in measures for environmental conservation as an ecological alternative. The review highlights the current application technology in forestry, the main methods of weed control, until it reaches the function of the electric weeding. The main characteristics, functioning and some hypotheses for the insertion or not of forestry equipment have been reported. The activity of electric weeding in forestry in a given region and time of year is unviable in relation to technical and ecological criteria, due to the risk of fire when there is a lot of dry matter on the soil.

“…In South America, huge areas of land is cultivated with transgenic varieties and intensive production. Landers et al (2016) gives some solutions for organic soybean production focusing on weed control. Moreover, the maintenance and recovery of soil fertility by adopting less aggressive cultural practices require great effort and inputs in order to thoroughly analyse the soil nutrient dynamics and their interactions.…”

Sustainable cropping systems that balance agricultural productivity and ecological integrity are urgently needed. Overreliance on soil tillage and herbicides to manage weeds has resulted in a number of major environmental problems including soil erosion and degradation, biodiversity loss, and water quality impairment. Combining organic farming and conservation agriculture is a viable alternative to address these challenges. In particular, mulch-based no tillage systems can be used to reduce tillage in organic production, improving soil quality while decreasing labor and fuel requirements. This technique involves planting cash crops directly into terminated cover crops that remain on soil surface and serve as mulch to prevent weeds establishment and protect soil from erosion. Despite potential benefits, adoption of organic mulch-based no tillage is limited due to challenges with cover crop termination, weed suppression, and yields. Here, we (i) review international research on organic mulch-based no tillage systems (soybean and maize), (ii) identify production issues that limit the success of this technique, and (iii) outline research priorities. As result, organic mulch-based no tillage is knowledge intensive and requires advanced planning and careful management of the cover crop. Primary challenges include timely cover crop establishment and termination, nutrient management, reduced soil temperature and moisture at planting, and achieving adequate seed-to-soil contact when planting into thick mulch on soil surface. Long-term research is needed to better understand the effects of this technique production on soil health and on the broader environmental and economic impacts. To increase adoption of organic mulch-based no tillage, future research should focus on (i) screening species and cultivars to identify cover crop and crop combinations that optimize cropping system performance and (ii) developing equipment for improving cover crop termination and seed placement. Research conducted in partnership with farmers will be valuable for developing guidelines and increasing adoption of this technique. Keywords Direct seeding. Organic farming. Residue. Roller-crimper.
