Abstract:
Within agroecological monitoring, an essential role is played by the biological monitoring, because surveillance of
living organisms provides precious information regarding the vitality of agroecosystems and quality of environmental
factors, essential for the quality of agricultural products and natural resources. The goal of earthworms’ complex
research is establishment of the high efficient agrocoenoses, ecologically balanced, stable, based on the rational usage
of the nutritive substances of soil, vegetable rests, water, and finally the application of environment-friendly
technologies. From this point of view, earthworms can be used within the agroecological monitoring, because they can
be easily extracted from their environment without affecting the population assembly. Essential for earthworms’ habitat
is soil texture and soil humidity, physical-mechanical properties, organic debris, both quantitatively and qualitatively.
The soil of the researched ecosystems was represented by calcic (carbonated) silt loamy chernozem. The limits of
plasticity, resistance to penetration, and adherence of soil are influenced by humus content, fertilization type, and
diversity of agrocoenoses. The forest strip and fallow farmland can contribute by providing with information the
Database of background and agroecological (impact) monitoring. During the droughty seasons, earthworms were not
found in soil, but a maximal number has been identified in forest strip (76 worms/m2
) at 0-30 cm depth, which
represents a hiding habitat during the arid periods.
