Abstract:
In this study the effect of natural zeolites and zeolites added with micro-organisms for the growth of cabbage (Brassica oleracea var. capitata L.) was evaluated, in order to highlight whether the microbiological component is the basis of the functionality of zeolites. The 3 experimental groups in cultivation were: 1) group without zeolites (CTRL) (peat 100%), irrigated with water and substrate previously fertilized; group with natural chabazite (CN) and fertilised substrate; group with chabazite enriched with micro-organisms (CM) and fertilised substrate. (Patented formula rif.28106IT/MB/BF). The test showed a significant increase in the agronomic parameters analyzed in plants treated with natural zeolites and zeolites with the addition of micro-organisms compared to the control. Also with regard to the physiological analysis of plants there was a significant increase in the parameters analysed, in the thesis treated with zeolites with the addition of micro-organisms and natural zeolites compared to the control. Finally, it should be noted that in the thesis treated with zeolites enriched with micro-organisms and in that with natural zeolites, the experiment also showed an increase in the percentage of germination of seeds and a significant reduction in the average time of germination compared to the untreated control (CTRL). The use of zeolites, as demonstrated by this test, can guarantee the grower a qualitative improvement of the plants in cultivation, ensuring better management of the use of fertilizers and water for irrigation. The zeolites are able to interact actively with the organic components present in the soil or brought with the fertilization, and have the ability to make more available the mineral and nutritional components present within their crystal lattice, based on the needs of the plant.
