Abstract
The article explores the potential for increasing the productivity of vegetable crops while reducing environmental impact through the use of natural zeolites—specifically clinoptilolite from the Shankanay deposits (Kazakhstan)—as a base for modified fertilizers. A vegetative experiment on dark chestnut soil demonstrated that zeolite and modified zeolite fertilizer (MZF) positively influence the growth, productivity, and quality of tomatoes and beets. In tomatoes, zeolite increased shoot length to 48 cm, fruit weight to 64 g, and leaf area to 28.9 cm². MZF provided the highest leaf area (32.1 cm²) and elevated levels of dry matter (5.9%) and sugar (3.75%) while reducing nitrate content to 89 mg/kg. In beets, MZF increased root crop weight to 342 g, sugar content to 8.4%, and reduced nitrate content to 224 mg/kg. Zeolite and MZF also contributed to the reduction of heavy metals in plants. Zeolites slow nutrient leaching, extend fertilizer effectiveness, and enhance plant resistance to stress. MZF showed the greatest synergistic effect, ensuring optimal plant nutrition and ecological safety of the produce.
