The purpose of this study was to study the effect of growing soil water and to compare the effectiveness of growing saffron with the use of dry leaves as biological mulch with bare soil in maintaining moisture, soil temperature, and minerals. The experiment divided the area into 4 types: (1) bare soil, (2) soil in which vegetables are grown, and (3) soil for planting vegetables + shredded dry wood, (4) soil for planting vegetables (full-leaf dry wood), and measurement of soil moisture, temperature, and minerals for a period of 4 weeks. Studies have shown that plots where vegetables are grown have a better soil moisture value than bare soil. When planting vegetables together with mulch, the leaves do not tear, and the torn leaves are ground cover. It was found that soil moisture is no different from growing vegetables alone, but using untorn leaves as mulch can be preserved. The N, P, K values of the soil are better than in other conditions. Bio mulch is an effective approach to soil and water conservation, can reduce soil erosion problems in sloped areas, increase water efficiency, and help create a suitable environment for the growth of economic crops. The results can be applied to the agronomy system for restoration of degraded areas and sustainable management of natural resources.
