Current agronomic practices are defined by two components: technology and biological dynamics. The response of agroecosystems to applied technologies is visible in the structure and interrelations of the biological component, which defines the actual fertility of soils. In soil-plant-soil biota system, both soil and plant have a rich history in terms of analysis and dynamics. Soil biota is a relatively new component studied, but without an integrated mapping. The response of soil micro-flora and -fauna to technological pressure is found in fertility level, resilience potential, yield stability and conservative status of soil. Mycorrhizas are co-evolutionary symbiotic partners of most cultivated plants. The complex of fungi-roots is defining overall nutrients absorbtion, plant nutrition and productivity. In this context, development of a mycorrhizal mapping system has a high value represented by an improvement of agronomic technologies. The design of mycorrhizal maps can serve to create a management adapted to the specific conditions of agricultural holdings and to increase productivity.
