RESEARCH REGARDING THE USE OF BIOLOGICAL FERTILIZERS FOR THE GROWTH OF AGRICULTURAL PRODUCTS, IN THE CONDITIONS OF CURRENT CLIMATE CHANGE

Abstract

Soil is the main component of agricultural ecosystems and for the growth and development of humans and animals, this being the most important component in the process of food production for humans and animals. Climate change from recent times as well as excessive chemicalization on agricultural crops have led to the phenomenon of soil degradation, namely its acidification. Soil acidification has led to a degradation of beneficial processes in soil and plants but especially to the decrease in agricultural productivity and, implicitly, the decrease in the amount of food for humans and animals. The present paper want to present a new type of fertilization technologies, the fertilization products based on live bacterial cultures. This paper highlighted the effect of live bacterial cultures used as biological fertilizer on agricultural crops in research and development stations for agriculture in Romania. Three living bacterial cultures (Azotobacter chroococcum, Azospirillum lipoferum and Bacillus megaterium) were used as materials and observation methods, soil monitoring methods (the amount of nutrients in the soil), methods of monitoring crops (crop phenophases) were used as research methods. , methods for monitoring pedo-climatic factors (temperature, precipitation etc.). The results obtained within the two groups showed a series of differences that were much more visible in the fertilized group with the three live bacterial cultures (compared to the chemically fertilized group). The most important aspect (like as results) that made the difference between the two batches was the production, the production of the fertilized batch with the three living bacterial cultures being higher than the chemically fertilized batch.
