The large-scale commercial agriculture that has recently been introduced to the region profoundly affects the functioning of these soils. Increasingly, termite mounds are leveled and considerable volumes of termite mound materials are being spread and mixed with the plowed horizons of commercial farms. Given the particular properties of termite mounds (alkaline pH, nutrient enrichment) the physical mixing of these materials with the soils of the plowed horizons induces a great spatial heterogeneity of the properties of the soil on a small scale. However, so far there is very little information showing how these practices modify the chemical and physical properties at the field scale. However, it is a major challenge because the variation in soil fertility induced by these practices has a great impact on the production of plant biomass. In addition, the observations show a temporal difference because plowing spreads and mixes the materials of termite mounds which become more and more exposed to pedogenetic processes (dissolution-precipitation, fragmentation, erosion, leaching, etc.).
