“…Between crops, the SL decreased by 85% from the 1st to the 3rd cropping cycle in the control treatment, in numerical terms (Table 4), influenced by soil consolidation and by the fact that most of the soil readily available for transport was eroded in the 1st cycle, as also verified by SCHICK et al (2017). The rainfall did not influence, since the precipitated volume increased 10% in this period (2,850 m3 in the 1st crop, 2,120 m3 in the 2nd crop, and 3,130 m3 in the 3rd crop) (FONTANIVE 2016).…”

“…Crotalaria produced more DM than millet and oats, with a small numerical distinction between millet and oats (Table 3). This is due to the physiological and morphological distinction between the cultivated plant species and to the climatic distinction between the cultivation seasons (different times), as verified by SCHICK et al (2017). The DM yield differed between the SS doses and the zero-dose.…”

Water (WL), soil (SL), phosphorus (P) and potassium (K) losses by water erosion and subsurface flow are influenced by soil management and by soil fertilization with swine slurry (SS). The study was conducted between 09/2014 and 11/2015, in a Haplic Dystrudept, to evaluate the 0 (zero), 50, 100 and 200 m³ ha-1 SS doses applied to millet (Pennisetum americanum), black oats (Avena strigosa) and crotalaria (Crotalaria ochroleuca), compared with a soil without cultivation and without SS. The soil total porosity (Tp) and macroporosity (Ma), the P and K concentration in the soil, in the runoff, and in the subsurface flow, the dry mass of the aerial part (DM) of crops, and the WL and SL were determined. The main results show the application of SS in the soil results in an increase in Tp and Ma, as well as in the concentration of P and K in the soil and the DM of the plants, in relation to the absence of SS. Water erosion decreases with an increased dose of SS applied to the soil in the interval between 50 and 200 m3 ha-1. The increase in the dose of SS increases the concentration and total losses of P and K in the runoff and decreases the concentration of these nutrients in the subsurface flow in the interval between 50 and 200 m3 ha-1. The increase of DM of the plants, in the interval between 13.75 and 22.82 t ha-1 , decreases SL at an average rate of 2.90 t ha-1. The concentration of K in the subsurface flow water was negatively related to the concentration of the element in the subsurface flow.

“…The similarity between these relationships and those found in the aforementioned literature was not expected, in part because they were obtained in forest condition, while those of other authors were found under agricultural conditions. As to the case of the relationship between SL and rain height (Figure 1b), the increasing linearity was also not expected, since SL increase linearly with increasing rainfall energy (Wischmeier and Smith, 1978;Schick et al, 2017). This type of relationship was also not expected here either, since this study was carried out in forest condition and the studies by Wischmeier and Smith (1978) and Schick et al (2017) were done under uncovered soil condition and with agricultural cultivation.…”

“…The soil water content before rainfall and the rainfall height are variables that strongly influence the surface runoff (Wischmeier and SMITH, 1978) which, in this case, was the main agent causing erosion, since the soil was practically covered by the litter. In areas where the soil is covered by the vegetal residues, water erosion is mainly explained by surface runoff water (Panachuki et al, 2011;Schick et al, 2017).…”

-Soil tillage influences the development of forests planted in the initial phase, which affects some hydrological processes and water erosion. The objective of this study was to quantify the water losses (WL) and soil losses (SL) by water erosion, between the second and third years of eucalyptus (Eucalyptus benthamii) crop, in an experiment located in southern Brazil, on a Humic Dystrudept. Was study three soil tillage treatments: i) subsoiling in downslope direction (SD); ii) subsoiling in contour on the slope (SC); iii) manual holes (MH). The plots had a dimension of 12 x 24 m, being the slope-wise length the greatest, monitored by tanks placed at the lower end for runoff collection. Runoff volume measurement and sampling for subsequent calculation of WL and SL was carried out weekly, corresponding to the rains accumulated during the week. The crop of eucalyptus in SD treatment, weakened the soil as to the water erosion in relation to the crop made in SC and in MH; the difference was 25% for the WL and 53% for the SL. Eucalyptus reforestation played an important role in the control of water erosion, regardless of the type of soil tillage. The SL due to water erosion were more influenced than the WL, regardless of the type of soil crop used. WL and SL are related to each other and to rainfall height in positive linear relationship, regardless of the type of soil preparation used for eucalyptus planting.Keywords: Reforestation; Water loss; Soil conservation. EROSÃO HÍDRICA EM TRÊS MÉTODOS DE PREPARO DO SOLO NUM CULTIVO DE EUCALYPTUS BENTHAMIIRESUMO -O preparo mecânico do solo é uma das operações mais importantes de manejo na fase inicial de desenvolvimento das florestas plantadas, pois afeta alguns processos do ciclo hidrológico e a erosão hídrica, sendo, por isso, importante o conhecimento dessas variáveis. Com o presente trabalho objetivouse quantificar as perdas de água e solo por erosão hídrica pluvial, entre o segundo e o terceiro ano de cultivo do Eucalyptus benthamii, em um experimento situado no Sul do Brasil, sobre um Cambissolo Húmico alumínico léptico, em três tratamentos de preparo do solo: i) preparo com subsolagem a favor do declive; ii) preparo com subsolagem em contorno ao declive; iii) preparo em covas com coveador manual. As parcelas tinham dimensão de 12 x 24 m, com o maior comprimento no sentido do declive, monitoradas por tanques colocados ao seu final para coleta da enxurrada. A medição do volume e a coleta de amostras da enxurrada para posterior cálculo de perdas de água e solo foi realizada semanalmente, correspondendo às chuvas acumuladas na semana. O preparo do solo a favor do declive apresentou perdas de água e solo maiores do que em contorno e em covas, cuja diferença foi 25 % para as perdas de água e 53 % para as perdas de solo. O crescimento das plantas ocasionou sensível diminuição do escoamento superficial, evidenciando que o reflorestamento, nas condições experimentais, pode controlar a erosão hídrica. As perdas de solo por erosão hídrica foram influenciadas em magnitude...

The aim of this study was to evaluate the phosphorus (P) extraction ability of the methods Mehlich 1 (M-1), Mehlich 3 (M-3), anion exchange resin in strips (AER-ST), and anion exchange resin in spheres (AER-SP), as a function of clay content, P rates, and incubation time. Experimental units were built with 20%, 40%, 60%, and 80% of clay and five different phosphorus rates as follows: 0, 100, 200, 400, and 600 mg P kg −1 , with subsequent incubation for 0, 30, and 90 days. After that, the samples were subjected to the analysis of extractable P using the M-1, M-3, AER-ST, and AER-SP extractors. All P extraction methods evaluated were sensitive to clay content and to the amount of added P. The input of P increased the recovery of this nutrient by all extractors, but this was less effective when the clay content of the soil was increased. In general, the ability of phosphorus extraction from the soil followed the order: M-1 > AER-SP > M-3 > AER-ST. The longer contact time of P with the soil, lower is the extracted P content, regardless of the extraction method, this being more evident in clayey soils. All extraction methods tested are sensitive to clay content, incubation time, and to the P concentration applied.
