Crop rotation implementation may change physical and chemical characteristics of the soil and has been recommended to improve soil quality. In Colombia, some producers implement different rotation systems in potato crops, and it is important to know the potential that they can bring to these production systems. The objective of this work was evaluating the physical and chemical characteristics of the soil after using crop rotation schemes. Three rotation systems were evaluated (1. potato-potato-oatmeal, 2. potato-oatmeal-pea, 3. potato-pea-potato) in lot 49 of research center Tibaitatá Agrosavia (Colombian Corporation of Agricultural Research), located in the municipality of Mosquera, department of Cundinamarca (Colombia). Soil samples were taken at the beginning and end of each evaluated rotation system, subsequently performing physical-chemical analysis in the laboratory. In the rotation systems, no statistically significant differences were observed (p > 0.05) in the physical properties studied, but the potato-oat-pea rotation system showed a higher pH (p < 0.05) compared to the other treatments evaluated. It is important to increase the availability of nutrients such as phosphorus, boron and zinc without altering the physical properties of the soil at the end of the rotation cycles, so they can be used in the development of potato plants subsequently planted.
