“…Salehi et al (2016) also showed that the canopy composition in stands of eastern Phage had great influence on the nutrient flow of Tf. Caggiano et al (2014) found an increase in K + levels in the Tf: 572 and 486% for Fagus sylvatica L. and Spruce abies L., relative to the incident precipitation. Calil et al (2010) studied the precipitation via nutrient inputs in the southeast of Rio Grande do Sul.…”

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.

“…Work developed over 2 years by Shen et al (2013) in the city of Heshan, Southeast China showed an average contribution of 110 kg ha -1 representing about 15 times more than for the present study. Evaluating nutrient uptake via precipitation incident in Bulgaria over 15 years, Caggiano et al (2014) found an average deposition of 11.5; 3.6; 3.0; 21.3; 1.4; 23.1 and 39.5 kg ha -1 for Ca 2+ , K + , Na + , total N, Mg 2+ , Cland SO4 3respectively.

Seasonal variation of atmospheric nutrient deposition in the western part of Rio Grande do Sul, Brazil

The chemical composition of rainfall is influenced by natural or anthropogenic factors; the amount of nutrients deposited is increased by the amount of rainfall. This work sought to estimate the amount of nutrients deposited by precipitation in the Pampa biome, the seasonal variation of the chemical composition of rain water, and the origin of nutrients found in the water. Precipitation collectors were installed in the open area to measure precipitation volumes biweekly over 2 years, and the samples were chemically analyzed. Concentrations of nutrients in the rain water increased over winter; however, since there was less precipitation, the total deposition was similar to the other seasons. Correlation analysis using the Pearson coefficient showed a negative correlation between rain volume and ion contents, indicating a dilution effect. The total amount of nutrients from precipitation during the study was 72.7 kg ha-1, representing an average of 36.3 kg ha-1 year-1. The Ca2+ and K+ ions are predominantly of litholical origin, whereas the SO42- and NO3- ions were of anthropogenic origin. The balance between the sum of cations and the sum of anions was shown to be unitary, indicating excellent data validation. The input of these nutrients occurs gradually, avoiding excessive losses, increasing the stock in the soil.
