The goal of our investigation is to established the influence of the drip irrigation associate with plastic mulch on the state of soil compactness, especially on the surface of the ground on the paths. In present, the aspect of soil surface (smooth or rough), the presence of small irregularities, the rill on the paths, the cracks formation after water evaporation and soil drying are the most useful indicators for farmers in order to assess soil degradation by compaction. To all these indicators, we added hysteresis of soil-water characteristic curves as indicator of compactness state of soil and quality yield. Hysteresis behavior of water is a soil characteristic curve and can be used by engineers in charge with design of irrigation system to avoid the negative effects of drip irrigation associate with plastic mulch technology. For avoid the soil degradation from greenhouses or solarium, we proposed a set of indicators for farmers to achieve first steps of soil degradation and for improve the irrigation management.
