“…Respostas positivas têm sido encontradas pelo fornecimento de Ca ao eucalipto, pela aplicação no campo de calcário, avaliado aos 8 meses de idade (ROCHA et al, 2008), calcário e silicato, avaliado aos 48 meses (SILVA; COELHO, 2010), calcário e lama de cal em vasos (SIMONETE et al, 2013).…”

“…The lime and gypsum applications increased the soil Ca because these products contain this nutrient (SIMONETE et al, 2013, CRUSCIOL et al, 2014. Differently from the expected, Mg availability reduced with liming; this was attributed to a possible specific adsorption of this nutrient.…”

“…The positive response to liming can be attributed to the improvement of the soil chemical attributes, especially the decrease of exchangeable Al, which favors the growth and metabolism of roots and, consequently, of plants. This result was also found by Simonete et al (2013). Therefore, this supply of essential elements such as Ca and Mg to the plants and the possible increase in soil available P are important for the development of plants (ERNANI, 2016).…”

Eucalyptus crops in Southern Brazil are generally conducted in acidic soils, thus their yield can be increased by lime and gypsum applications. The objective of this study was to evaluate the effect of lime and gypsum applications on soil chemical attributes and initial growth of Eucalyptus benthamii and Eucalyptus dunnii in a Humic Cambisol (Inceptisol). The experiment was conducted in a greenhouse, with seedlings of both species of eucalyptus grown in soil treated with different rates of lime (0, 3, 6, and 12 Mg ha-1), and gypsum (0, 6, 3, 12.6, and 25.2 Mg ha-1). At 90 days after application of the treatments, the soil chemical attributes and growth components of eucalyptus seedlings. The lime increased the production shoot dry weight, however, the response to gypsum was negative. The lime increased the soil pH, exchangeable calcium (Ca), base saturation (V %), and slightly the soil electrical conductivity, decreased the soil aluminium saturation (m %), and promoted little reduction in the exchangeable potassium (K) and magnesium (Mg) contents. The gypsum didn't alter the soil pH, but decreased the m%, increased soil phosphorus (P) contents, and expressively increased the electrical conductivity, which may have had a negative effect on the eucalyptus growth. In conclusion, the addition of limestone decreases the soil acidity and benefits the growth of eucalyptus seedlings. However, the addition of gypsum has no expressive effects upon those variables, but it can decrease the growth of seedlings when the rates are excessive.

“…Lime sludge is a byproduct of wood cooking liquor clarification derived from the cellulose extraction process and contains high calcium (Ca) contents, similarly to those found in calcitic limestone. According to Simonete et al (2013) and Maeda et al (2015), when applied to soil, it reduces acidity and aluminum (Al) levels while elevating calcium (Ca) and sodium (Na).…”

“…The reduced magnesium content (Mg) present in lime sludge is a limitation for the use of this material, as evidenced by Simonete et al (2013) in a study carried out with Eucalyptus saligna cultivated in Quartzarenic Neosol.…”

The industries of cellulose and paper have generated large amounts of solid waste and effluents which have been used as soil conditioners and source of nutrients to improve physical and chemical attributes of areas growing forest species. This study analyzes the spatial and temporal variability of Eucalyptus urograndis regarding the chemical attributes of soil treated with cellulose residue. The fertilization of an experimental area in the Três Lagoas county used a lime sludge/Oxyfertil ® compound with a 2 ha. experimental grid containing 50 sampling points set up over it. Plant and soil samples were collected during three consecutive years
