Abstract The investigation was conducted in the 2019–2020 agricultural season Al-Thaghr area, north of Basrah Governorate, Iraq (latitude 31.145288N and longitude 47.431334E), clay soil. Two factors were used investigation. first factor three tillage systems (heavy by mouldboard plow, low chisel no-till system). second concentrations biocide Trichozon (4 g m -2 , 2 without adding pesticide). ex...

This article presents a control approach that enables an autonomous operation of fleets of unmanned snow ploughs at large airports. The proposed method is suited for the special demands of tasks of the airport snow shovelling. The robots have to keep a compact formation of variable shapes during moving into the locations of their deployment and for the autonomous sweeping of runways surfaces. T...

The study aims to justify the design scheme and main parameters of combined aggregate for soil preparation cotton sowing on ridges. authors have developed technology ridges its implementation. are presented. unit consists a mouldboard deep loosener with sloping rack ridge maker. basic principles methods classical mechanics, mathematical analysis, statistics were used in this study. optimum cons...

In almost any scenario for ’cosmological’ gamma-ray bursts (and in many models where they originate in our own Galaxy), the initial energy density is so large that the resulting relativistic plasma expands with v ∼ c producing a blast wave ahead of it and a reverse shock moving into the ejecta, as it ploughs into the external medium. We evaluate the radiation expected from these shocks, for bot...

The combination of isotope trace technique and SOC fractionation allows a better understanding of SOC dynamics. A five-year tillage experiment consisting of no-tillage (NT) and mouldboard plough (MP) was used to study the changes in particle-size SOC fractions and corresponding δ (13)C natural abundance to assess SOC turnover in the 0-20 cm layer of black soils under tillage practices. Compared...

Farm machinery selection, operation and management directly impact crop cultivation processes outputs. A priori quantification of technical financial needs allows definition proportionate distribution available resources simplification selection process. Appropriate planning, association adjustment the power unit implement are required for soil cultivation. Consideration functional parameters i...
