I has focused my efforts:

1) Are there relationships between changes in carbon isotopes fractionation in soil and root, which could be associated to leaf gas exchance perfomance?
2) How I can improve the soybean root development and its functional perfomance when submitted to pluviometric oscillation in claypan soils?

I think so a integrative approach of different areas of expertise, aiming to advances in the frontier of scientific knowledge concerning the resulting interactions of plants with the soil environment that make up each system, could allow the development of biochdemical/physiological and diversity metrics biological (soils and plants) as a means of monitoring such systems in terms of losses and gains over time and, mainly, to mitigate the impacts abiotic stresses on crops grow on claypan soils.
