AGRICULTURAL SOIL QUALITY MONITORING IN WEST REGION PUBLISHEDAlexandrina MANEA1, M. DUMITRU 1, Irina CALCIU1
Abstract:. On the whole agricultural land of West Region, the agricultural monitoring system of level I (16x16 km) totalizes 89 sites. Every site was characterised from morfologic, physical (particle size distribution, structural instability index, the degree of compaction, saturated hydraulic conductivity, resistance to penetration), hydro-physical (wilting coefficient, field water capacity, useful water capacity, total water capacity, maximum transfer capacity) and chemical (soil reaction, soil percentage base saturation at pH8.3, humus content, total nitrogen content, mobile phosphorus and mobile potassium) characteristics. Distribution of monitoring plots by land use shows the most plots are found on arable land (56%) followed by grassland (28%), meadows (14.6%) ad orchards – 1%. At this region level, 9 classes are found from the whole 12 existent classes and 15 of the 32 soil types listed in SRTS, 2012. Compared with soils identified at national level (Dumitru et al., 2011), soil diversity is lower.
