A system for evaluating land suitability using fuzzy logic method has been developed. The system determining a degree of delimitation, land ratings, suitability classes, and their actual land suitability subclasses of given land characteristics. The main parts of the evaluation process, which included in the fuzzy inference engine of the knowledge based system, are fuzzification and defuzzifica...

Soil salinization can have an inhibitory effect on crop productivity and pose a serious threat to regional agricultural resource utilization sustainable development. However, there are scarce studies the quantitative impact of soil productivity. The purpose this study is identify spatial temporal characteristics cultivated land, degree, net primary (NPP) vegetation in Shandong region around Boh...

Soil salinization and sodification, caused by inadequate land management, is one of the main threats to semiarid agroecosystems. It essential investigate saline levels under different land-use conditions maintain sustainability agricultural production. The objective this study was diagnose salinity status soil in region Northeast Brazil. samples were collected surface layer (0–5 cm) three condi...

the main objective of this research was the measurement of soil characteristics, land evaluation and determination of potential yield of sugar beet in yekanat plain of marand. for doing this, firstly, yield potential of sugar beet was estimated by fao method and secondly land evaluation of different soil units for sugar beet cultivation was determined by parametric method. results showed that m...

A study was conducted to determine suitable soil properties as soil quality indicators, using factor analysis in order to evaluate the effects of land use change on loessial hillslope soils of the Shastkola District in Golestan Province, northern Iran. To this end, forty surface soil (0-30 cm) samples were collected from four adjacent sites with the following land uses systems: (1) natural fore...
