Title : The impact of agricultural crops and fertilizers used on the bacterial population of the soil and in particular on nitrifiing and denitrifying bacteria

Abstract:

Modern agriculture appears to have a very diversified impact on the soil not only for the crops used but also for the type of fertilizer used. One of the least studied impacts is that on the soil microbiome. Maintaining a stable soil microbial community structure is crucial in preserving soil production potential and overall soil health. Various nitrogen (N) addition strategies induced changes in soil physicochemical properties which are correlated with alterations in microbial community structure and partial microbial abundance, thereby displaying differences in carbon and nitrogen use efficiencies. Therefore it becomes important to analyse how the microbiology of the soil and the effects of the fertilizers used can vary. This study analyses the impact of the different kind of fertilizer on the Nitrogen concentration in the soil and the variations of microorganisms in the soil that can be linked to the nitrogen cycle based on the main cultures present in the region and on the different agronomic practices used. This case study allows us to identify as it is possible to analysed the nitrogen concentration in the soil and how nitrifying and denitrifying bacteria react. Through the use of Real Time PCR for the identification and quantification of nitrifying and denitrifying bacteria, it was done a study of the are very important in the ecological stability of the soil for a good practice in the agriculture system. The analysis of these bacterial types therefore allows us to outline a global picture of possible future treatments and the different forms of nitrogen that can be used for plant health and to avoid environmental impacts.

Audience Take Away Notes:

• New kind of investigation of the nitrogen in the soil
• This study creates the basis for a new vision of fertilizer use in agriculture
• Allows monitoring of nitrogen compounds to avoid environmental contamination
• It is a practical solution to improve soil quality

Biography:

Dr. Angelantonio Calabrese studied Biology applied to the enviromental at the CNR IRSA, Italia and graduated as MS in 2005. He create a research group at the Institute of Water Research Institute of the CNR He was created a new kind of research to analyzed the environmental status through the analyses of the bacteria population. She has published more than 50 research.
