Abstract:
Use of zeolitic material from Munella region (Albania), as fertilizer in the sandy soils of Divjaka region (Albania). In Munella region, Albania there are important zeolitic resources, which have various applications in agriculture. The zeolites in this area have been used in experiments as fertilizers in the sandy soils of Divjaka region (Central-western Albania). Lolium multiflorium was used as experimental plant. The experiment was realized in the green - house of the Tirana Agricultural University. Natural zeolites of Munella occur as separate layers hosted by andesite-dacite volcanic sequence of the eastern-type Albanian ophiolites. The zeolite assemblage consists of Stilbite-Stellerite solid-solution. Their cation-exchange capacity ranges from 192-242 meq/100g. They have strong affinity for the cations of Pb2+, Cu2+ and Zn2+ up to their concentration in solution. On the other hand, the respective concentrations of the introducing cations in zeolite are 137, 81 and 65 meq/100g, which are below the above measured cation-exchange capacity value. |
