Interactions between scientific knowledge and traditional knowledge in the evaluation of soil consistency

Abstract

The traditional knowledge about the soils, are still disregarded, although there is already work
exposing its importance. The objective was to evaluate soil consistency by relating scientific
knowledge to traditional peasant knowledge and existing interactions. The areas were defined
by the peasants according to the agricultural uses, P1 - Haplic Cambisol (Agroecological Area),
Yellow Red Latosol (Native Forest Area) and P3 - Flúvico Neosol (Permanent Preservation
Area), In the municipality of Governador Dix Sept Rosado, RN. The consistency was determined
from Liquidity Limits (LL) and Plasticity (LP). In the P2, there was a decrease in the limits
due to lower clay content in the horizons, except for the latosolic B horizon, where high weathering
elevated LP and LL, the farmers identified the differentiation between the superficial
horizons and the diagnoses. There was a close relationship between the scientific classification
and that of the peasants.
