Soil Sampling(Ernest)

Soil plays a more than important role in the life of our planet. It is from the soil that we build houses, roads, cars, airplanes and so on, using metals extracted from the soil. However, as the population grows, the land that is nothing but soil is shrinking in the face of our ever-increasing population. Our objective in this context is based on the agricultural context, the soil-plant relationship. According to Professor OMOKO MICHEL, "a soil is born, grows and dies". It is therefore important to understand that the soil is a living antithesis. In agronomy, samples are often taken for a simple reason - to know the nutrient content of the soil - to provide the missing fraction of nutrients or to reduce the excess the granulometry of the soil the size of its aggregates (sand, silt, clay) - soil chemistry (NPK) -soil biology and microbiology. Sampling, as in all scientific contexts, must be representative and must also comply with regulations. - the depth of the sampling, -the number of samples - the type of sampling. With this in mind, we took samples from our experimental plot in order to carry out some preliminary tests as part of our study on the interactions between mud snails and rice production
