  3. Introduction Introduction Soil is an important resource which supports a large number of ecosystem goods and services from which humankind benefits, being terrestrial environment with the largest biodiversity. The capacity of the soil to maintain key ecological functions is known as soil quality. Soil face a large range of challenges, like :

  4. Microbial Community in Soil Microbial Community in Soil In soil the microbial community play an important role in: • decomposition and stabilization of organic matter • immobilization and mineralization of nutrients • plant growth and nutrient uptake. One of the parameters used to assess the impact of land use in soil microbial One of the parameters used to assess the impact of land use in soil microbial community size, activity, composition and diversity is the soil microbial respiration, which can be used as indicators of soil fertility, which if drop indicates a decrease in soil quality and health. Only a small fraction of soil microorganisms can be identified by conventional methods, that is why functional diversity can be used to understand microbial community.

  5. Objective Objective The objective of this study was to assess the results of reviewed papers and the importance and efficiency of the MicroResp method in determining the physiological profile of the microbial community.

  6. MicroResp Method MicroResp Method A method which can be used to assess the soil microbial community is MicroResp . The deep-well plate is used used to to load load soil soil samples and carbon sources and the detection plate is a system which detect the evolved carbon dioxide using cresol as an.

  16. MicroResp in Romania MicroResp in Romania In Romania MicroResp method is just at the beginning but there are PhD theses which used this method to determine community level physiological profile. -Valentina SANDOR – Assesing the impact of edaphic biological communities on biochemical processes in the soil to energy plants. - Susana SFECHIS - Researches influence of zeolite on productivity elements - Susana SFECHIS - Researches influence of zeolite on productivity elements and microbiological activity on spring barley, soybeans and maize at ARDS Turda.

  17. CONCLUSIONS CONCLUSIONS MicroResp is a method which can be used in range studies for understanding soil microbial community like the effect: • Pollution on the community; • Fertilizers; • Plant; • • Another treatments and soil managements. Another treatments and soil managements. After reviewing all the studies we can affirm that MicroResp is an appropriate method, rapid and sensitive for determination of microbial community functional diversity .
