An improved method for establishing soil moisture regime under irrigation conditions is presented in this paper. In contrast to the traditional approach the researches proceeded from the hypothesis that the maximum moisture limit that can be maintained in the soil may differ from the field water capacity (FWC). Six variants of maximum soil moisture limits and six variants of minimum soil moisture limits were established. Soil moisture regime variants were chosen in such a way that watering rate is the same for equal moisture intervals but differing in their superior and inferior limits, which is impossible according to traditional approach. It was determined that because of the reological properties of the soil, classical procedures of calculation considerably diminish water content in the soil. Maximum and minimum moisture level, which could be maintained in the soil, can range in the following limits (0.7-1.0) FWC. Soil moisture regime,maintained according to classical approach, has a lower rainfall retention capacity than the one presented in this work (0.7-0.9) FWC. |
