Abstract

Outdated technologies prevent the civilization from its development in the context of globalization. There is a preventing factor to apply the nature-resembling technologies that is a generally accepted simulation frontal gravity continuum-isotropic paradigm of irrigation and drainage, which causes soil destruction and loss of fresh water. The work presents the results of a model experiment carried out in the framework of an innovative scientific and technical approach known as Biogeosystem Technique applied for the empirical demonstration of soil and water conservation opportunities provided by the intra-soil pulse continuum-discrete moisture paradigm are presented. The model system is a vegetative plastic transparent cylinder 20 cm high with a diameter of 5 cm having the ordinary chernozem soil inside. This sample soil was previously grated and poured as a layer of 0-30 cm, with compaction approximate to the natural structure and density of soil. Then we simulated pulse continuum-discrete water flow inside the soil using the syringe of 20 ml and the medical spinal needle with a length of 12 cm. The experiment was carried out at the initial stage of spring-planted barley under natural insolation. We performed a surface irrigation, sprinkling, drip irrigation, and a new intra-soil pulse continuum-discrete method of soil moistening. After surface irrigation, sprinkling, drip irrigation we observed water seepage through the soil in the amount of 30-50 % of the given volume. After watering, we observed total subsidence of the surface, as well as the formation of crust on it. With the drip irrigation, there was also the surface subsidence and crust formation, but the processes were local taking place directly under the dropper. With pulsed intra-soil continuum-discrete moistening, the soil surface preserved its form as it had after filling the experimental model with soil, as the crust is not formed. The model system produced better developed barley plants with a new method of moistening, and the water consumption was 1.5-2.5 times less than with the standard methods of watering plants
