This article presents the results of a technology of placing a plastic film in the space between cotton rows. We have studied physical and mechanical properties of soil before placing the film. We have proved that the plastic film in the spaces between the cotton rows retains moisture in the soil much longer and it is possible to obtain up to 22 kg/ha of raw cotton in the condition of water scarcity in the Karakalpakstan.

The goal of the measurement of the tractor ZTS 164 45 equipped with digital electrohydraulical control EHR-D BOSCH during ploughing with ploughs KUHN (4 bottoms) and 5 PHX 35 (5 bottoms) was to obtain time dependent states of pressure in the hydraulic system of the three point hitch of tractor. From the point of view of comparison of obtained results testing conditions were determinated with respect to physical and mechanical properties of soil such as soil volume mass, soil humidity, penetration resistance and shear resistance of soil. Beyond these measurements also measurements of operation parameters as a&nbsp;ploughing depth, ploughing width, working speed and fuel consumption were accomplished. The measured results of physical and mechanical properties of soil show big content of loam elements and stones in the soil. Simultaneously the measured results of the operation parameters of the ploughing sets confirmed that the ploughs KUHN and 5 PHX 35 are suitable for tractor ZTS 164 45. Based on the measured results there is a possibility to infer following conclusions: Control system of the three point hitch offers a reliable function. Hydraulic circuit is equipped by an improper distributor which causes pressure peaks which are corres-<br />ponding with safety valve adjustment. Hydraulic circuit has a&nbsp;low conductive resistance. Loading of tractor body is higher when using mounted plough than with semi mounted plough.

Properties Of Soil

Bintan Island is a part of Riau Islands Province. On this island, the capital city is Tanjungpinang. The compliance of public facilities such as landfill waste is a priority in this city. Landfill design that suitable in this area is a sanitary landfill system. The soil layer uses to cover the waste in this landfill system. The closure did gradually avoid the disruption of waste processing. The type of soil for its landfill cover has to be able to control the leachate. It controlled by the permeability of the soil. The methods used in this study are the analysis of the physical and mechanical properties of soil. Rock and soil samples are obtained systematically through trenching. Sampling-based on changes in physical properties of soil that reflect its mechanical properties. A probabilistic approach used to solve the problems and to get accurate results. The geomorphology of the study area divided into four units. They are very flat terrain, flat terrain, slightly steep hills, and steep hills. The sample used for the study is undisturbed soil. Analysis of the physical and mechanical properties of soil shows the types of soil, such as SW, GM, MH-OH, and CH. However, MH is the most dominant type of soil. Each of the soil types represents a certain degree of weathering. The degree of weathering in the study area varies from the III degree to VI degrees. Rocks are weathering form clay mineral, which compiles the soil. Clay mineral in the soil layer is varied from quartz, illite, kaolinite, gibbsite, goethite, and hematite—the impact of the swelling of clay. The swelling of clay in the study area ranged from low to high. The properties and composition of the soil are affected by the permeability value.

Abstract Field testing is often a very reliable way to determine the mechanical properties of soil materials and in some cases the most appropriate and unique way to obtain accurate measurements. Geotechnical engineers and engineering geologists perform geotechnical investigations to obtain information on the physical and mechanical properties of soil and rock underlying (and sometimes adjacent to) a site to design earthworks and foundations for proposed structures. The object of the present work is the recording of the geotechnical data of the center and districts of the city of Larissa, the knowledge of which is necessary for the construction and erection of construction works, as well as the characteristics and points that need special attention in each area. Finally important conclusions refer to the construction culture, that project authorities and contractors should draw on, accordingly.

Loading Analysis

This contribution is oriented on the field of dynamic loading analysis of three-point hitch of tractor hydraulic pump. The hydraulic pump is placed in circuit of three-point hitch of the tractor ZTS 160 45. Obtained data from operation experiments will be applied for simulation of dynamic loading of the tested hydraulic pump. The measurements were realized during position control with ploughing sets: tractor ZTS 160 45 + plough 5-PN-30 and tractor ZTS 160 45 + plough 7-PHX-35. During the test physical and mechanical properties of soil and operating parameters of ploughing sets were investigated. Pressures of hydraulic system were in range from 3.2 to 7 MPa at aggregation with plough 5-PN-30 and hydraulic pump was loaded. Pressures of hydraulic system during ploughing with ploughing set tractor ZTS 160 45 + plough 7-PHX-35 were in range from 1.8 to 14 MPa and two times hydraulic pump was unloading in time 2 seconds.

Recently, bioengineering has been approached as one of the slope stabilizations techniques as it is inexpensive compared to the mechanical stabilization technique. However, numbers of slope failure still reoccur due to the limitation of the bioengineering technique knowledge. Proper bioengineering material and methods must be carefully selected to overcome the problem. The objectives of this research are to determine the physical and mechanical properties of soil with Vetiver Grass roots as well as the root properties of the Vetiver Grass since these grass types have been applied widely for slope stabilization. The physical properties of soil lab tests have been determined such as compaction test, Atterberg limits test and sieve analysis test. The mechanical properties of soil with and without root grasses have been carried out through the shear box test. For the identification of the root properties of Vetiver Grass, the root morphology and the diameter of the root has been identified. The results for the lab tests conducted showed that the soil with roots have a higher shear strength compared to soil without roots included with FOS (Factor of Safety) calculation proving that the soil with the aid of Vetiver Grass will be effective in retaining soil.

Properties Of Soil

During statistical processing of proceeding of several variants of experiments the equation of maximum pressure of tractor wheels on the soil were obtained, depending on the tractor parameters and physical and mechanical properties of the soil. This paper analyzes the influence of the main factors on the maximum amount of wheels pressure on the ground. We revealed performance of equations beyond the experimental values of the factors. With an increase in the width of the wheel profile, its diameter, the speed of the tractor, the maximum pressure of wheel on the ground is reduced, and with increasing tractor’s weight on one wheel, the soil hardness, the pressure in wheel tire the maximum pressure of wheel on ground increases. Comparison with the data, available in the domestic and foreign journals, showed that the most stable prediction results of maximum pressure value of tractor wheels on the ground are obtained by using the first equation in the article. The prediction error of wheels maximum pressure values is in the range of 3 to 15%, depending on the brand of tractor and its working conditions.
