Despite its importance for terrestrial nutrient and carbon cycling, the spatial organization of microbial activity in soil and in the rhizosphere is poorly understood. We related carbon allocation by roots to distribution of acid and alkaline phosphatase activity in the rhizosphere of Lupinus albus L. To do so, we further developed soil zymography e an in situ method for the analysis of the two-dimensional distribution of enzyme activity in soil e integrating fluorescent substrates.
