“…Pearson's correlation also shows the inverse relation between the pluviometric indexes and the ion concentration. This finding can also be observed in other studies such as Valente et al (2016) quantifying the nutrient input in Eucalyptus urophylla × Eucalyptus globulus stands. According to Laclau et al (2003) this can be explained by the effect of dilution of the ions as precipitation increases.…”

Atmospheric deposition is responsible for the ions input, which may be due to dust and aerosols and rainfall. During rainfall a portion is intercepted by the tree canopy and returned to the atmosphere by evapotranspiration, another part crosses the forest canopy called throughfall and stemflow. The objective of the present work was to quantify the nutrient input of the incident rainfall, throughfall, stemflow and canopy enrichment in an Eucalyptus dunnii plantation, established in soil with low natural fertility. Four plots of 20 m × 21 m were demarcated. The rainfall consists 3 rain collectors in an open área. The throughfall consisted 3 collectors per plot in the line, interlining and diagonal positions of the trees. The stemflow consisted in the installation of three systems per plot formed by a hose in the trunk of the tree that leads the solution to a reservoir. Through rainfall, 29.5 kg ha-1 of nutrients were supplied. When we consider the sum of the throughfall and stemflow, the amount of nutrients was 77.6 kg ha-1. After interaction with the tree canopy 48.2 kg ha-1 of nutrients were incorporated. Potassium showed the highest enrichment: 607%. The average nutrient enrichment was 163%. The input of N and K via incident rainfall was 1.8 and 3.1 kg ha-1. Considering the fertilization described in the methodology, this contributed amount represents 6.1 and 2.6% of the total. If we consider the rotation of 7 years for Eucalyptus dunnii, the contribution at the end of rotation represents 42.4 and 18% of N and K2O. The interaction with the canopy of Eucalyptus dunnii enriches the rainwater with nutrients making the solution with a more basic character.

“…The calcium contents were 0.42; 0.71 and 2.73 for P, Tf and Sf. Although Valente et al (2016) found higher levels of the element in P than in Tf, Cornu et al (1998) suggested that the washing of exudates from the decomposition of branches contributed to the increase in Tf.…”

“…According to Valente et al (2016), the distribution of nutrients in forest biomass varies over time. With the dynamics of the ecosystem in the juvenile stage, the process is more accelerated, stabilizing when the forest reaches ages greater than ten years, as is the case of the area with Eucalyptus sp., which is 11 years old.…”

Root biomass plays a vital role in nutrient cycling for the maintenance and functioning of different ecosystems. In this context, this study aimed to determine the stocks of elements in root biomass under different covers in the Cerrado of Tocantins, Brazil. The research was conducted in different vegetal coverings: agriculture, pasture, Eucalyptus sp., and native Cerrado forest. Root biomass was collected in six trenches, 70 x 70 cm, and a depth of 50 cm through sieving. Macro and microelement stocks were determined in root biomass. Macros and microelements showed higher average values for the native forest. With the change in vegetation cover, N, P, and S were higher in agriculture, with stocks of 1.82 Mg ha-1, 1.83 Mg ha-1, and 9.6 Mg ha-1. In a planted forest of Eucalyptus sp., macroelements K, Ca, and Mg were higher, with stock values of 16.06 Mg ha-1, 25.91 Mg ha-1, and 5.02 Mg ha-1, and microelements, B, Cu, Fe, Mn, and Zn with values of 0.05 Mg ha-1, 0.04 Mg ha-1, 5 Mg ha-1, 0.7 Mg ha-1, and 0.08 Mg ha-1 in root biomass, respectively. Thus, the planted forest of Eucalyptus sp. promoted greater stocks and cycling of elements, with greater stability of the organic material.
