Why soils are so important?


Like water and air, the soil is essential for our current existence. Historically, the soil has been a big component in our societies' foundation, playing a important in the creation of agriculture, leading to sedentarism and the development of our actual lifestyle. The soil has also played a significant role in migration, globalization, and the economy, facilitating the connection and exchange of products and traditions between different countries. Moreover, soil holds huge biodiversity, being an essential foundation for worldwide ecosystem functions and one of the most significant mediators for photosynthetic organisms. Besides these facts, soils are great water filters, provide essential nutrients to plants, contain substantial amounts of organic carbon, and are one of the primary regulators of greenhouse gases and temperature. Currently, more than 85% of our food is produced directly or indirectly in the soil, making our existence dependable on them. 


My research interests focus mostly on soil because they are essential for life as we know it. Still, human impacts have increased land degradation, especially by erosion, contamination, carbon loss, salinization, and biodiversity loss. That is why one of my goals with my P.h.D. research is to understand a little bit more the interactions of plants with soil, especially how does root traits can affect dryland soil properties.
