Comprehensive evaluation of soil fertility quality on urban turf

Soil sample with the terf soil in Changli campus of Hebei Normal University of Science Technology was collected, and some physicochemical properties such as soil bulk density, pH, CEC, total salt content, organic matter, hydrolysable nitrogen, available phosphorus, available potassium were studied, and each soil fertility factor was made a numerical treatment in this paper. Through the way of membership function and the partial correlation analysis, the membership value and its weight of each fertility factor were determined, and the paper comprehensively evaluated soil fertility quality by fuzzy mathematics assessment. The result showed that the turf soil comprehensive fertility was low, which was consistent with the turf quality. This indicated that this assessment method was feasible, and it was helpful to appraise the urban turf soil fertility condition scientifically, reasonably and accurately. Besides, it could enhance the soil fertility conditions and improve the turf quality.
