USE OF NATURAL ZEOLITE IN LAND TREATMENT
1. SOIL MODIFIER AND FERTILIZER.
Natural zeolite splendidly plays part of soil modifier as a fertilizer of the soil before planting of various seedlings, including those of decorative and coniferous trees, fruiters and bushes, flowers, flowers in pots, medicinal herbs, etc., when preparing substrates and soil mixtures for the open land.
Advantages:
- good physical properties, namely, non-consolidation, flowability, water-absorbing quality, great absorption capacity due to a developed system of canals and pores, a great ion-exchange capacity (up to 160 mg equivalent per 100 g),
- absorbs well ions of ammonium and nutritive substances;
- is environmentally friendly, convenient for storing, transporting and introducing into the soil. It may be applied together with mineral or organic fertilizers. Good results are attained when it is mixed with peat.
- splendidly aerifies the soil, facilitates development of the root system and growth of the whole plant, retains a sufficient quantity of water in the area of roots - 40 to 70 percent of its own weight, operates as a reservoir for storing fertilizers: nitrates, phosphates, potassium, nutritive substances and most important components for plant health and growth. Catches and holds fertilizers in its branched structure until plant roots find them. Nitrogen retained by zeolite is insoluble in water and is not washed out for a long period of time.
- saves fertilizers. Less fertilizers, especially nitrogen ones, are washed out into ground water. Improves absorption of fertilizers by 20 to 40 percent. Without the use of natural zeolite about 35 percent of nitrogene is washed out of the root area into ground water, contaminating it with nitrates and nitrites;
- facilitates the process of optimizing acidity of sandy, flow-water, volcanic and sod-podzol soils, prevents compaction of mineral fertilizers during storage;
- reduces the entry of toxic substances and radionuclides from the soil into plants. Natural zeolite sorbs radionuclides and heavy metals available in the soil, transferring them into a bound state, as a result, they are not washed out of the soil but are absorbed by plants.
