The soil and forest vegetation relationship in the light of the analysis of some properties of brown soil over limestone in the karst region of western Croatia

In this work the impact of vegetation on the properties of brown soil over limestone in the karst region of western Croatia has been investigated. The investigation was carried out in five dominant climazonal communities. The results suggest significant differences for some properties of brown soil over limestone (the parameters explaining relatively well the soil organic matter status) between individual forest associations. In addition, littoral the forest associations are very well discriminated from the continental ones. The specific influence of a plant species (although this was not the objective of the investigations) is recognisable in the forest associations with pure beech stands which can be attributed primarily to the influence of litter (plant tissue). The discriminating analysis proved to be very suitable for the determination of the impact of vegetation on the organic complex properties in brown soil over limestone. By including a larger number of pedophysiographical parameters, and using the discriminating analysis, their connection with vegetation characteristics could be explained in an even better way.
