The aim of this study was to investigate the influence of different soil types from the Cetina river basin on germination and growth of bean, wheat and tomato stalks. The analysis of physico-chemical properties of the soil was made twice, using the GLOBE protocol at nine sites from the source to the mouth of the Cetina River during 2020 and 2021. Traveling down the Cetina, different soils were determined according to their texture. Using the GLOBE protocol, the consistency, structure and texture of the soil, soil pH, soil permeability and water retention capacity were determined. The results of the research showed that sandy soils have significantly higher permeability than soils in the area of karst fields that have more clay in their composition. Samples of sandy, loamy and clay soil were taken for further work and examination of plant germination. The results of the experiment showed that the type of soil does not affect the onset of germination of bean, tomato and wheat seeds. The percentage of germinated wheat and tomato plants is highest in loamy soil, while the highest percentage of germination of bean seeds is in sandy soil. The results also show that loamy soil is best for the growth and development of all plant species because after the thirtieth day from the beginning of sowing there is a drying and decay of plant individuals growing in sandy and clay soil.
