“…Some researchers have evaluated responses to management practices using improved genetic material, mechanical site preparation, control of competing vegetation, and fertilization in Pinus plantations, and found positive results in the relationship between productivity and soil chemical attributes, significantly improving the growth of species when best tillage practices were recommended (Albaugh et al 2010, Batista et al 2015. Other studies have reported that successive cycles of Pinus plantations without nutrient replacement tend to cause a nutritional deficit for the trees, resulting in low productivity in forest plantations (Gatiboni et al 2017, Gatiboni et al 2020). Therefore, assessing soil microbiological attributes and their relationships with chemical and physical soil characteristics, combined with site-specific silvicultural management practices in Pinus taeda, provides a better understanding of soil nutrient dynamics (Sixel et al 2015, Tulio et al 2022.…”

Over the last decades, Pinus taeda L. plantations in southern Brazil showed a great increase in average production. However, the gains in productivity obtained by genetic selection and breeding have nowadays stabilized. Research on edaphic factors and silvicultural practices is currently performed with the aim of both increasing the productivity of P. taeda plantations and maintaining the soil quality. To this end, soil microbiological attributes are considered better indicators of soil quality as they are more sensitive than chemical and physical ones. In this study, we aimed to evaluate the relationship between microbial activity and the physical and chemical parameters of different soil types under young Pinus taeda plantations at five different sites in southern Brazil. Soil samples were collected at depths of 0-5 and 5-10 cm. The soil microbiological attributes evaluated were: potentially mineralizable nitrogen (PMN), microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), microbial basal respiration (MBR), and metabolic quotient (qCO2). We also evaluated some physical and chemical soil parameters. Sites with the highest values of C, clay, and nutrients in the soil, showed higher values for the soil microbiological attributes, compared to the other study sites. The previous management with minimal tillage in some sites seems to positively affect soil quality. The MCB and MBR showed better sensitivity in indicating differences between sites and showed a good relationship with clay content, C/N ratio, K, and pH. These results suggest that site-specific characteristics such as soil type or forest management influence soil microbiological attributes in Pinus taeda plantations during initial growth in southern Brazil.

“…Where introduced in South America, similar silvicultural practices have been largely followed, except for fertilizer use, even if plantings occurred on low fertility soils (Motta et al 2014). In Brazilian planted pine environments, soil nutrient depletion suggests a need for implementing fertilizer and lime applications (Sixel et al 2015, Gatiboni et al 2020.…”

Biogeosciences and Forestry Biogeosciences and ForestryWood production and nutritional status of Pinus taeda L. in response to fertilization and liming: a meta-analysis of the Americas Valdécio dos Santos Rodrigues (1) , Antônio Carlos Vargas Motta (1) , Julierme Zimmer Barbosa (2) , Tamires Maiara Ercole (1) , Stephen A Prior (3) Loblolly pine (Pinus taeda L.) is one of the most planted forest species in the Americas. Since few studies have comprehensively assessed loblolly pine responses to fertilization, the present study performed a meta-analysis of the Americas based on 44 publications (1970-2022) of loblolly pine fertilization under field conditions. In general, fertilization increased root dry matter (+33%), litter (+21%), plant height (+6%), trunk diameter (+9%), wood yield (+30%), and needle concentrations of P (+9%), K (+36%), Ca (+17%), Mg (+14%), and S (+12%). Wood production was higher with residue fertilization, primarily with use of composite residues (cellulosic sludge + ash), compared to mineral fertilization. In regards to mineral applications, wood production was higher when multiple nutrients were added from fertilization and liming operations. Applications at planting (< 1 year) or on established trees (2-8 years), showed similar increases in wood production with higher responses occurring on sandy soils. These factors generally increased needle nutrient concentrations, except for no alteration or slight decreases in N under most conditions. The present study revealed loblolly pine responses to contrasting application strategies, which can help identify efficient fertility management practices for this commercially significant tree species.

“…No Brasil, as florestas plantadas com o gênero Pinus cobrem 1,93 milhões de hectares . Pinus taeda é frequentemente cultivado em solos de baixa fertilidade natural, como o fósforo (P), comumente sem fertilização e com sucessivas rotações no mesmo sítio, promovendo a exportação de P do solo, explicando a baixa produtividade (IMA < 20 m 3 ha −1 ano −1 ) (Gatiboni et al, 2020).…”
