Erosion Pins: Installation, Readings, and Calculations of Soil Losses under the Effect of Hydrogel

Erosion pins are considered a simple and inexpensive way to estimate soil losses due erosion have been used in different environments with degrees types of erosion. Despite the advantages this technique, there is shortage studies that demonstrate how data systematization loss calculations performed using technique. Therefore, study aimed present step-by-step process obtained field calculation losses, measurement under effect hydrogel. Readings from 16 installed an area cultivated soursop trees planted on contour lines associated stone rows were monitored weekly between 19/02 19/03/2022 by measuring distance surface end each pin. The readings organized pin date measurement. Subsequently, lowering burial, density, useful pin, kg/m3 Mg/ha-1 determined, enabling statistical analysis technical interpretation data.
