“…According to Table 1, the soil used in this work has sandy characteristics. Sandy soils have lower water retention when compared to clayey soils because they have a higher frequency of pore size with radii greater than 0.03 mm (Libardi, 2018;Silva et al, 2014), this means that higher energy needs to be used to remove water from these soils (Ekwue & Seepersad, 2015;Zambon et al, 2021), so it is important that in case of repetitions of this methodology for clayey soils, the same results will not be found.…”

Since there are several methods used to determine soil moisture, the objective was to compare the moisture values obtained with the use of a gas oven and a microwave to the values obtained with the standard oven method. Having been carried out at the Hydraulics Laboratory of the State University of Maringá, Umuarama Regional Campus, the performance of the methods was evaluated in the determination of five levels of moisture (10, 15, 20, 25, and 30%), with dry masses obtained at 15, 20, 25 and 30 minutes for the gas oven and at 2, 4, 6 and 8 minutes for the microwave. The best drying times were selected using the Taylor Diagram. Linear regression was performed between the methods, in order to obtain the correlation coefficient (r), the Willmott agreement index (d), the performance index (c), absolute error (EA), absolute mean error (ERA), and root mean square error (RQME). By analyzing the results obtained, it can be stated that the gas oven method and the microwave method presented excellent performance when compared to the standard method. It was also concluded that the time of 25 minutes for the gas oven method was efficient and, for the microwave method, the drying time of 8 minutes was sufficient, meaning a reduction in the time for moisture determination.

“…Rainfall characteristics are one of the major factors affecting splash erosion (Comino et al, 2016). In this case, the depth of rainfall does not have a strong influence, but is more affected by maximum rain for a short time up to 1 hour (Nanko et al, 2008) and the splash detachment will decrease with increasing rainfall (Ekwue & Seepersad, 2015). When the intensity of rain increases, interception of the forest canopy decreases (Bahmani et al, 2012) so that erosion increases (Fernández-Raga et al, 2019).…”

In smallholder cacao plantations, the protective crops used varied, so they have different effects on splash erosion. The management of land cover with a canopy of cacao and shade trees on cacao fields, aims to control of splash erosion. This study was conducted by directly measuring the magnitude of splash erosion under several levels of canopy cover. The magnitude of splash erosion was determined by measuring the depth of the eroded soil using the bottle cap method. The measurements were carried out every rain event (46 rain events with rainfall varied from 0.28 to 97.04 mm). The canopy cover level was determined by analyzing the images taken using a digital camera. The images were processed by Matlab software with closure approach. The data were analyzed by regression analysis to determine the relationship between canopy cover level and the depth of splash erosion that occurred. The results showed that the level of canopy cover influence the depth of splash erosion. In addition, this study indicates that the level of splash erosion not only influenced by the level of closure and rainfall, but also strongly influenced by the size of the leaf cover. Keywords: Cacao plantation, Canopy cover, Regression analysis, Splash erosion.

“…It is an organic sediment formed by partial decomposition of vegetal matter in acid and humid media, containing low-oxygen amounts. In the last thirty years, the peat has been much studied, primarily in Canada, the US and Europe, as alternative technology of using a natural adsorber [29][30][31]. Low cost, applied to the treatment of water and effluents contaminated by heavy metals and other toxics substances.…”
