“…The differences observed in the environmental and economic pillars may be related to the high number of harvesting operations in forest plantations (68%). This requires information on their economic efficiency [86,87] as well as their impact on the soil (soil compaction) in order to adapt silvicultural treatments against soil compaction (soil conditioning) [88,89] for future forest conversions or forest stand reforms. The aspects of the social pillar are related to the strict certifications and labor laws that require compliance with health and safety regulations.…”

Purpose of Review The comprehensive assessment of timber and fuelwood harvesting operations through the consideration of the three pillars of sustainability: Economic, social, and environmental has not received much attention. The use of criteria can significantly improve impact assessment. Therefore, the objective of this review paper is to compile and analyze the most commonly used criteria and indicators for each dimension of sustainability in logging operations over the last 6 years. This review provides an overview of these criteria for different harvesting machines, geographical areas, slope classes, time periods, types of research, and silvicultural treatments. Recent Findings The environmental pillar was the most studied (46%), followed by the economic pillar (38%). Productivity was the most investigated criterion (15%). On the one hand, productivity is linked to the environmental and social pillars, as it is related to the level of greenhouse gas emissions, energy consumption, and the employment rate. However, productivity is mainly used as a criterion of financial interest, as it is most often studied in combination with costs. In addition to productivity, the other most frequently examined criteria were costs (10%), soil nutrients (9.5%), and soil compaction (9%). The social dimension was the least studied pillar (16%). This may be due to a lack of knowledge of social sustainability issues in this area. Summary Sustainability is achieved when all three dimensions are balanced. The results of this review show an imbalance, with economic and environmental aspects being weighted more heavily than social aspects. Balancing all three dimensions typically requires an assessment of trade-offs. This review provides a comprehensive summary of the criteria that have been studied to date and can be used as a checklist and guideline for future sustainability assessments of harvesting operations.

“…Com a prática do plantio direto, e para que se tenha um melhor aproveitamento do tempo, o investimento em tecnologia mecanizada é imprescindível. No entanto, essa tecnologia pode ter efeitos negativos no solo devido ao aumento do tráfego de máquinas e carga exercida sobre o mesmo, influenciando assim em sua estrutura, no aumento da resistência à penetração, maior densidade, aumento da macroporosidade e diminuição dos macroporos, resultando na sua compactação (Castioni et al, 2021;Rodrigues et al, 2022).…”

A compactação do solo é um dos entraves na produção de grãos no cerrado, podendo influenciar na produção de biomassa e alterações fisiológicas, como a produção de clorofilas, nas plantas de cobertura utilizadas para minimizar os danos da compactação e proteção do solo. Assim, objetivou-se avaliar o efeito da compactação do solo na produção de biomassa e teores de clorofila a, b e total de plantas de cobertura. O experimento foi desenvolvido em casa de vegetação, na Universidade de Rio Verde. Os tratamentos foram estabelecidos pelo esquema fatorial 4 x 2, sendo Urochloa ruziziensis, Panicum maximum – BRS zuri, milho consorciado com U. ruziziensis e milho solteiro, cultivados em solo com e sem compactação. A compactação do solo reduziu a biomassa de todas as plantas de cobertura. O milho solteiro e em consórcio com U. ruziziensis crescidos em solo sem compactação forneceram ao solo quantidade maior de biomassa superficial (massa seca da parte aérea e total), enquanto que o consórcio do milho com U. ruziziensis em solo compactado proporcionaram maior massa seca de raízes. Comparando os teores de clorofila a, b e total dentro da própria espécie observa-se que não houve aumento do teor de clorofila quanto a compactação do solo. Portanto, conclui-se que a compactação do solo prejudica a desenvolvimento da biomassa, mas não altera os teores de clorofila das plantas de cobertura.
