Summary: It is well known that many scientific and expert institutions and individuals in Croatia and worldwide investigate the possibilities to reduce the pollution of natural ecosystems. Rich world literature on the topic show that technological contamination of ecosystems causes the harmful effects on biological and biochemical reactions in land and water ecol-systems. Lack of knowledge of the ecosystems, neglecting of the undesirable accompanying phenomena of the technology, especially of the pollution, uncontrolled emission from the stationed and mobile sources, use of chemicals in agriculture and forestry, contamination of water, are the most obvious and most frequent reflections of the transformation of the relation to its environment. Therefore, it is necessary to stimulate development of endogenous sciences and technology in all areas relating to biological sources on the earth and natural environment. The exchange of experiences acquired by research, among countries with similar ecological and bio-climatic conditions in particular could have outstanding advantages. For example, the problem of degradation and fertility of soil deserves greater attention in our country and it is a prospective research field of all scientific branches dealing with studies of the soil as a component of -ecol-system. We have devoted our research to: - the improvement of the quality of the degraded soils by application of special natural substrata, SPS; - the protection and purification of the underground waters by application of domestic natural minerals-zeolites.

Keywords: SNS - special natural supstrate, fertilization, neutralization, calcification, microbiological fixation, simulation of growth, denitrification.

Research goals: The ecological issue that recently attracts the greatest attention is the contamination of soil and water by nitrates. Therefore, we have directed our research towards these problems. Our aim is to investigate the efficiency of the application of the natural lime-stone materials, and special natural substrata (SPS) with silicate-carbonate base, on fertilization and neutralization value of the treated acid soils. The main goals of the research were: 1. to determine fertilization and neutralization value of some natural substrata based on soft lime-stone, dolomite, and zeolite tuff, in raising the fertility of acid soils, 2. to investigate the impact of these materials primarily on some chemical characteristics of the soil, i.e. on the intensity and dynamics of these changes, 3. to investigate the impact of the type and dose of these materials on some important ploughing field crops, and to make conclusions on their application in practice. Since the underground (drinking) water has been contaminated with high contents of nitrate, which is caused by intensive agricultural production, i.e. intensive fertilization with easy fusible nitrates, the impact of the SPS on NO3 - in the underground water has been observed. It is our intention to make such fertilizer that would contain 50 % less easy fusible nitrates in fertilization. By the application of natural zeolites in SPS composition, ion exchange of NH4 ions and absorption of NO3 has been made. The results of our studies have been published in many essays and papers presented at international meetings.
