MONTICO, Sergio  e  DI LEO, Néstor. Evaluación de perfiles culturales en ambientes degradados por erosión hídrica. Cienc. docencia tecnol. [online]. 2015, n.51, pp.395-403. ISSN 1851-1716.

Water erosion has high incidence in agricultural production. In this work, a qualitative-quantitative method for assessing the quality of the cultural profile in environments degraded by water erosion is proposed. The method was applied in ten environments within a farm of the southern of Santa Fe, Argentina. Soil is a Typic Argiudoll and average annual rainfall is about 980 mm, the R value of the usle is 550 mj mm ha^-1 h^-1. Signs of water erosion were surveyed and observation wells were made in each environment. The categories for assessing the quality of the cultural profile (vcpc) were: Poor, Fair, Good and Very Good. No Very Good cultural profiles were found and 60 % of the evaluated area show cultural profiles between Poor and Fair. The method was effective to discriminate between different situations affected by water erosion process.
