Marker land plots for digital reclamation of agricultural lands

The reliability of the results of remote remote sensing of reclaimed lands significantly depends on the degree of manifestation of features on the digital image, which most closely reflect the parameters of the reclamation regime of soils. To increase accuracy and efficiency of the probing results, it is proposed to create markers (specialized areas) on the reclaimed zones that adequately reflect the main parameters of the reclamation regime of soils and the state of plants. Drainage areas with variable drainage intensity along the drains length are to be arranged on the drained lands. Position of boundary of waterlogging zone is fixed in section. Parameters of reclamation regime of drained lands are estimated by position of border. Increased doses of nitrogen fertilizers are applied to marker land plot of irrigated land. Intensive growth of the vegetative part of plants is accompanied by increased transpiration. According to the dynamics of the number of plants with subsiding leaves, a decision is made to water the entire array of irrigation. Marker land plot has been tested in the Moscow and Saratov regions. Positive test results were obtained.
