RAMOS-CARBAJAL, Ernesto; MARTINEZ-RODRIGUEZ, Arturo; LAFFITA-LEYVA, Alexander  e  AYALA-LOPEZ, Julio Cesar. Geometric and Kinematic Parameters of Sensing Tips for the Soil Strength Recording. Rev Cie Téc Agr [online]. 2017, vol.26, n.1, pp. 32-39. ISSN 2071-0054.

A research in order to evaluate the influence of several geometrical and operational parameters of sensing tips on the quality of on-the-go soil strength recording, was carried out in a Cuban typical Red Ferralitic soil. The considered parameters were the geometric characteristic of the sensing tip, the sensing speed and the protrude of the tip in front of the leading edge of the supporter shank. The experiments were carried out under controlled conditions in a Soil Chanel Laboratory of the Agricultural Mechanization Center of Havana Agrarian University. As a result was obtained that the tip with 30^o wedge prismatic form and 520 mm² base area, advancing horizontally to a speed non highest to 0,7 m.s-1 and protruded 110 mm or more in front of the leading edge of the supporter shank, constitutes the best alternative for “on- the -go” soil strength registration. Also it was determined that the sensing operation should be made when this type of soil presents a moisture near to 28%
