Soil quality assessment using fuzzy modeling
نویسنده
چکیده
A b s t I' act. Maintaining soil productivity is essential if agri culture production systems are to be sustainable, thus soil quality is an essential issue. However, there is a paucity of tools for mea surement for the purpose ofunderstanding changes in soil quality. Here the possibility of using fuzzy modeling theory as a means to address the problem of soil quality assessment is considered. For soil quality assessment, two general types of fuzzy soil quality indicators potentially could be defined. The theoretical conside ration of this process is illustrated with an example. Results indi cate that the fuzzy multi-attributive approach could be effectively utilized as a tool leading to better understanding soil quality. Ke yw 0 I' d s: soil quality, fuzzy indicators, fuzzy modeling

Soil compaction assessment at different grazing intensities using Adaptive Neuro-Fuzzy Inference System (Case study: Sabalan south eastern rangelands, Ardabil province)
Grazing intensity should follow the management roles to prevent the soil compaction. Soil compaction decreases plant root penetration so that at 2 MPa the root extension and above ground biomass will stop. In this research, digital penetrometer was used to assessment the soil compaction level in Sabalan region in Ardabil province caused by livestock. Grazing intensity and distance from villa...

This paper explores the use of fuzzy membership values generated by fuzzy c-means clustering (FCM) method to predict soil properties over space. A weighted average model was used on fuzzy membership to get soil properties. To validate the efficiency of this model, it was then compared with a multiple linear regression model between the soil property and terrain attributes. Four indices were cal...
