“…Therefore, K is very important for water defi ciency periods. Zn can also contribute to greater production in eucalypt plantations (Florentino et al, 2021).The higher concentration of Ca e S in the leaves with the use of manure may have infl uenced the higher development by the plants, since, according to Medeiros et al (2020), they are important elements for the trees'trunk and bark formation.…”

The nutrients contained in the liquid pig slurry (PS) make this residue a potential organic fertilizer for the cultivation of tree species for the production of wood, which can promote the circular economy. This research aimed to evaluate soil chemical parameters, nutritional status, and development of hybrid eucalyptus clone urograndis from PS application for three consecutive years. The treatments evaluated were without fertilization (C); mineral fertilization (NPK) – 300 kg ha-1 year1 of the 02-30-10 formulation; fertigation with PS of 200 m3 ha-1 year1 (FPS200); and fertigation with PS of 400 m3 ha-1 year1 (FPS400). Macronutrients and micronutrients from leaves and soil were evaluated. Tree development was analyzed using stem diameter at breast height (DBH) and total height (Ht). PS treatments resulted in leaves with higher accumulation of K and P and lower accumulation of N, Ca, M, S, Cu, and Fe. The treatments FPS200 and FPS400 presented DBH and Ht equal or superior to the mineral fertilization. Fertilizations with NPK, FPS200, and FPS400 resulted, respectively, in DBH increments 16, 27, and 30% higher than the control. Regarding the chemical attributes of the soil, the use of PS reduced the pH of the soil and increased the levels of P in comparison with the other treatments. The micronutrient values were adequate for fertility and no accumulation of potentially toxic elements at a level considered harmful was observed. The application of PS in eucalyptus hybrid urograndis proved to be an attractive alternative to increase wood production.

“…High soil pH tends to favor the growth of acid-intolerant bacteria at the expense of both acidtolerant bacteria and fungi (Wan et al, 2015), thus alternations of microbial communities in limed soils may at least partially explain changes in soil respiration. Meanwhile, the lime application can increase the availability of some nutrients (i.e., Ca and Mn), while decreasing the availability of some micro nutrients, such as Cu and Zn (Florentino et al, 2021). Therefore, alternations in plant growth under lime application may also explain changes in soil respiration.…”

ObjectiveLime application and understory plant clearance are two common forest management methods employed to increase forest productivity in subtropical regions. However, the effect of these two management methods, or their combined application, on soil respiration in forest plantation settings is still not fully understood.MethodsHere, a field experiment was conducted to determine how lime application, understory clearance, and their combined application, would impact total soil respiration (Rs), autotrophic respiration (Ra), and heterotrophic respiration (Rh) in a Chinese subtropical Eucalyptus plantation. Changes in soil microclimate and microbial community (PLFAs), as well as Eucalyptus fine root biomass were also assessed.ResultsLime application stimulated Rh, but decreased Ra of understory vegetation (primarily Dicranopteris dichotoma), thus consequently inhibiting Rs. Understory clearance also reduced Rs, primarily due to reductions in soil PLFAs and associated Rh, and Ra of understory vegetation. Since the increase in Rh induced by lime application was greater than the decrease in Rh caused by understory clearance, the combined application of lime application and understory clearance decreased Rs primarily by reducing understory root respiration.ConclusionOur observations suggest that understory plants can modulate the effect of lime application on Rs, highlighting the important role of understory vegetation in regulating soil carbon cycling in subtropical Eucalyptus plantations. We concluded that the potential interactive effects should be considered in developing management practices that optimize the yield and sustainability of subtropical plantations.

Litter removal impacts on soil biodiversity and eucalypt plantation development in the seasonal tropics

The little layer of tree plantations provides primary nutrients for uptake, buffers changes in soil moisture, and provides habitat and substrate to soil epigeic fauna. However, this layer in eucalypt plantations is often removed to reduce fuel load during the fire season in the Brazilian savanna (Cerrado). Therefore, it is necessary to quantify the effects of changes in litter dynamics on the function of these plantations, on key nutrient cycling processes and on epigeic fauna diversity and abundance. In two adjacent stands (one juvenile and one mature), the consequences of two years of litter removal were quantified as monthly litterfall, leaf and fine wood litter decomposition, epigeic fauna abundance and diversity, soil biogeochemical variables, and tree diameter and basal area increments. Monthly litterfall rates in juvenile and mature stands did not change with litter removal over the study period. Annual litterfall ranged from 4.1 to 4.9 Mg ha−1a−1 in litter removal plots and from 3.9 to 4.8 Mg ha−1a−1 in control plots. Fine wood litter decomposition was slower in litter removal plots compared to controls, while leaf decomposition rates were similar in both. Two years of litter removal in the juvenile stand did not affect topsoil biogeochemical parameters but decreased available phosphorus at 20–40 cm depth relative to controls. In the mature stand, total cation exchange capacity (0–20 cm) was higher in controls (6.4 cmolc dm−3) relative to litter removal plots (6.3 cmolc dm−3), while soil moisture (0–40 cm depth) was lower in litter removal (25.45 m3 m−3) compared to control plots (26 m3 m−3) in the dry season. A non-metric multidimensional scaling ordination revealed an increased homogeneity in epigeic fauna where litter was removed. Litterfall, decomposition, diameter increment, four soil physical parameters and fourteen chemical parameters at 0–20 and 20–40 cm depth explained the differences in soil epigeic fauna composition between litter removal and control plots. Diameter increment decreased with litter removal only in the juvenile stand, which had reached its growth peak. The results indicate that removing excess litter to decrease fuel volume can alter soil biodiversity and edaphic conditions that negatively affect nutrient cycling and tree growth.
