Physical properties of non-material objects are investigated. Physical definition of the physical non-material world is given. By physical methods the following conclusions were obtained: the  set is nonempty set; the  world is cognizable; physical non-material  objects of the  world act on material  objects of the material world and change a physical state of the material  objects; at least, some non-material  objects (but, probably, all or nearly all  objects) are capable to control interactions of material objects, energy balance of these interactions, energy pumping-over between material objects and transformation of energy from one its kind in another. Non-material  objects act by unusual non-forcing, non-energy way. According to physical laws of the material  world, the long-range action fields (LRA-fields), really, cannot exist, more precisely, these fields cannot exist as material objects. However, according to experimental data, LRA-fields really exist. LRA-fields belong to the  set and have the above properties of  objects. There is the single material - non-material world. The  and components of this world physically interact with each other, that necessitates the adequate development of physics. (Processes of a high level complexity, for example spirit actions, exceed the limits of physics competence.) The above conclusions are valid under the following restrictions on the long-range interaction: the energy conservation law is not violated; the actions are transferred at a distance by physical fields; thesis "the planets (and all the more stars) cannot influence on the Earth by means of energy fields" is valid. If these restrictions are violated, other explanations of the LRA-fields existence are not excluded. Discussion on different directions of thoughts is useful.

One of the main tasks of drip irrigation is to predict the geometric parameters of the moisture contours by estimating the impact of the water rate and the irrigation water on the moisture distribution in the soil. In this paper the soil water retention curve and function of moisture conductivity are used to simulate the process of moisture movement taking into account both the state and the type of soil. A software tool has been developed to automate calculations and visualize them. One of the main advantages of this software tool is that it allows using three-dimensional arrays of porosity values, specific surface area and initial soil moisture for each elementary volume of soil. The results of simulating various initial conditions make it possible to form contours and maintain optimum soil moisture right in the area of the plant root zone development. The correspondence of the simulation results to real data was verified by a series of laboratory and field experiments having light-gray forest soil. The calculated coefficients of determination have average values, that are quite high for such tasks, namely 0.68 (horizontal surfaces) and 0.72 (inclined surfaces).

Abstract. Many approaches to the evaluation of erosion technologies have been developed, but not all of them correspond to the reality of the processes that are taking place. The observed discrepancy is most likely due to insufficient consideration of soil parameters. These parameters on the sloping cultivated lands vary significantly and the slope drain hydraulics have their own principal features compared, for example, to river processes. The work substantiates the constructive-technological parameters of profilographs for controlling meliorative technologies on sloping cultivated lands. Identified certain difficulties in the design, implementation and operation of land meliorative activities are often associated with significant spatial and temporal variability of the main parameters of the underlying surface. It is proposed to use the method of determining the average slope by profilography of the tested underlying soil surface to determine these parameters. To implement this method, it is proposed to use a profilograph equipped with an encoder and a position sensor. As a result of the research, the direction and magnitude of the average soil surface slope of the field elementary section is determined, as well as the roughness and waviness of the treated soil surface. The diameter of the scanned circle is substantiated depending on the applied meliorative technology on the sloping cultivated lands as the main constructivetechnological parameter of the profilograph. Based on the results of theoretical studies, the dependence of the number of intersections with the midline on the scanned circle diameter and the width of the technological groove were obtained. The obtained dependence made it possible to calculate the recommended scanning radius of the soil surface by a profilograph for various soil-cultivating and anti-erosion machines, taking into account the microrelief or the crest of the soil after its treatment. The results of the theoretical studies are obtained from the test reports of the anti-erosion machines provided by the machine-testing stations on the sites of the MIS organizations and are presented in tables.
