“…Restoration encompasses different methods, all in response to degradation level, expected recovery time, speci c local constraints, and nancial resources (Martins et al 2021;Barbosa et al 2022;Oliveira et al 2022Oliveira et al , 2023. Regarding kaolin mining, in which the return of soil conditions can exceed 150 years (Lane et al 2020), trenches can be an e cient alternative to minimize impacts caused by intense soil compaction during mining operations (Ribeiro et al 2021).…”

Forest restoration in post-open pit mining areas is complex and faces the challenge of "recreating" the soil under horizontal disruption, representing strong barriers to root growth. Hence, trenches (paths opened by digging) for planting are an alternative to improve root development conditions and plant growth. This study aimed to evaluate growth of six tree species planted in trenches under three treatments: Topsoil or control (TS), Sawdust (SD) and Cow manure (CM). The trenches (1 m in height and length by 40 m long) were lled with topsoil. In the 6-m space between trenches, two treatments were performed: soil covered and not covered by sawdust to test natural regeneration. Six tree species (250 individuals) in pits over trenches where Mean Annual Increment in height (MAI Ht, ), diameter (MAI DSH ), crown area (MAI CA ), and survival were assessed. After 18 months, mortality was 2.4%, Clitoria fairchildiana, Tachigali vulgaris, and Croton matourensis showed highest MAI Ht and MAI DSH , and the C. fairchildiana presented the highest MAI CA with no statistical differences among treatments. Sawdust coverage had no effects on litter amounts and on tree species from the natural regeneration. Herbs and grasses covered 45.5% and 57.2% of the soil with and without sawdust. Based on growth and mortality, C. fairchildiana, T. vulgaris, and C. matarensis can be recommended for initial restoration after kaolin mining.

“…Furthermore, organic waste has high potential to remediate soils contaminated by heavy metals (Hu et al 2021). Organic waste is seen as a strategy to reduce restoration time, whether put in planting pits (Ribeiro et al 2021;Oliveira et al 2023) or spread over surface (Marcuzzo et al 2013; Barbosa et al…”

This study aimed to evaluate growth of six tree species planted in trenches under three treatments: Topsoil or control (TS), Sawdust (SD) and Cow manure (CM).

In the 6-m space between trenches, two treatments were performed: soil covered and not covered by sawdust to test natural regeneration. Six tree species (250 individuals) in pits over trenches where Mean Annual Increment in height (MAIHt,), diameter (MAIDSH), crown area (MAICA), and survival were assessed. After 18 months, mortality was 2.4%, Clitoria fairchildiana, Tachigali vulgaris, and Croton matourensis showed highest MAIHt and MAIDSH, and the C. fairchildiana presented the highest MAICA with no statistical differences among treatments.

Passion fruit cultivation relies on irrigation to increase yields in the semiarid of northeastern Brazil. Water scarcity is one of the factors that most affect crop physiology, leading to lower yields. Therefore, this study aimed to assess the influence of planting hole volume and application of a hydroretentive polymer on physiological and productive aspects of irrigated yellow passion fruit cv. BRS GA1 in the Northeast semi-arid region of Brazil. The experiment was conducted in randomized blocks, in a split-plot design 2 × (2 × 2). Treatments consisted of irrigation depths (100% and 70% of the crop's evapotranspiration requirement - ETc), planting hole volumes (64 dm3 and 128 dm3), and soil with and without application of hydroretentive Polymer (1.5 g dm3), with four replicates and three plants per plot. The analyzed variables included chlorophyll a and b indices, gas exchange, and yellow passion fruit yield. The findings showed that hydroretentive polymer application to the soil increases chlorophyll content and gas exchange in yellow passion fruit. Moreover, photosynthetic rates were not limited by a 30% reduction in irrigation depth and increased in plants grown in 128-dm3 planting holes with hydroretentive polymer. Based on yield results, irrigation depths can be reduced to 70% of the ETc by applying hydroretentive polymer in 64-dm3 planting holes.
