“…In a study conducted by Rodrigues et al (2016), the application of limestone promoted an increase in eucalyptus diameter, with greater increments in this dendrometric attribute than in vertical growth, similarly to the present study, which also showed greater increments in diameter than in height. In turn, Vieira & Weber (2017) FLORESTA, Curitiba, PR, v. 50, n. 4, p. 1788PR, v. 50, n. 4, p. -1797 obtained improvements in the soil chemical attributes after limestone application, which provided an increment in height, diameter, and biomass of E. camaldulensis seedlings. Rodrigues et al (2016) observed an increase in height, up to 1.50 m, on E. urophylla x E. grandis clonal plants cultivated in Cerrado, at 18 months after the addition of limestone, on the surface or incorporated.…”

“…The Eucalyptus, due to its high adaptability to climatic conditions and different soils, is considered as tolerant to acidity and low soil fertility, and as non-responsive to any soil correction (CQFS, 2016). However, several studies indicate an increase in productivity when using fertilizers and soil acidity correctives (CASTRO FARIA et al, 2015;WEBER, 2017;RODRIGUES et al, 2016;MAEDA et al, 2015;GUIMARÃES et al, 2015). Because of the high costs of applying these products, even at the beginning of the production process, and the scarcity of resources, the administration of doses below the necessary may occur, resulting in low crop yields.…”

The high demand for forest products in Brazil estimates a 2 million hectares increase in reforestation areas over the next 10 years, highlighting Eucalyptus species. However, these crops usually occur in acid soils that need correction to achieve high productivity. Besides limestone, lime mud, a residue from the cellulose industry, and gypsum can also be used as correctives, but there are doubts about doses and ways of application with the best results. Thus, were evaluated the soil chemical attributes, foliar nutrient content, and initial growth of a Eucalyptus dunnii Maiden crop in response to the application of limestone, lime mud, and gypsum in different doses and ways of applications, on a Humic Cambisol from Santa Catarina Plateau. The experiment was carried out with nine treatments in four replicates, where the evaluated parameters were determined up to 24 months after planting. In general, both limestone, lime mud, and gypsum, in different doses and ways of application, affected the chemical attributes of the soil but did not affect the foliar nutrient content at 12 months, height, and diameter at breast high (DBH) from trees and timber volume at 24 months. Gypsum do not correct soil acidity but lime mud provides similar results to limestone indicating that can substitute this corrective without damage to nutritional status and initial development of Eucalyptus dunnii.
