Influence Of Olive Mill Waste Water Spreading On Soil Microbial Activity. Short Term Effect On Carbon And Nitrogen Mineralization Process

Mineralization is the core of the symbiotic relation between soil - microorganism and plant. It is the generator of mineral elements essential to the plants nutrition. Microorganisms are the main biotic actors in this process. The product of the mineralization depends, on the one hand, on the biomass of the soil and on the other hand on the quantity, nature and characteristics of the organic matter. The monitoring of the mineralization is therefore essential after any input of organic matter with a view to its valorisation which effects are unpredictable. It is in this context that we propose to study the impact of the three successive annual intakes of OMWW on the process of mineralization of organic matter and the soil content of carbon and mineral nitrogen.
