Effects of Irrigation on Yield and Composition of Principal Elements of Nutrients in Maize-Growing Soil
Extensive organic production under irrigation conditions requires greater amounts of NPK fertilisers. Furthermore, the mobility of fertilisers, especially of nitrogen, is greater under the increased soil moisture content, ...
Results of the Investigation Effects of Soil Compaction on Yield of Winter Wheat
Moving of tractors and mobile systems can be divided in two groups: moving trough the inner parts of fields, and through the headlands. On headlands, soil compressing is more intensive due to lower moving speeds while ...
3D Discrete Element Model to Describe the Draft Force and the Influences of the Tool Geometry
Virtual DEM models were developed in correspondence with the real tests. In this article we will introduce the methods of how DEM approach was used in developing a model for the prediction of draught force on cultivator ...
Factors Affecting the Mechanization of Plant Production in Hungary
The natural and climatic conditions of Hungary are extremely suitable for agricultural production and producing raw materials. As a result of the historical conditions and the continuous changing of the structure of the ...
Optimization of Hydraulic Lifting System in IMR Tractors
Purpose of hydraulics lifting system in tractor is to obtain continuity in control of functioning with certain special tools which implements plow, i.e. should at least regulate the operation of the plow by„ position”, by ...
Technological Parameters of Briquetting of Miscanthus Biomass
In this paper, the specific characteristics of Miscanthus straw briquetting process are presented, as well as the problems and difficulties that may be expected in the processing of this new and potentially profitable ...
Long Term Effects of the Application of Ameliorative Tillage Systems on Heavy Mechanical Composition Soils in Crop Production
There are around 400,000 hectares of soils with heavy mechanical composition, and the greatest part of the production area is under crops. The long term soil tillage by conventional methods (using plough) and a large number ...
Research of Seeding Distance Uniformity by Response Surface Methodology
The subject of this paper is to optimize the uniformity seeding distances using response surface methodology and validated optimal level variables. Variables are modeled as a vacuum on the seed plate, diameter planting ...
Stator and Rotor Power of the Doubly-Fed Asynchronous Generator Applied in Wind Power Plants
Due to the stochastic nature of the wind, doubly-fed asynchronous generator can be used effectively in the process of transforming wind energy into electrical energy, especially for the case of higher power. A special ...
Using Tractor Test Data for Selecting Farm Tractors
The Nebraska Tractor Test Laboratory (NTTL) at the University of Nebraska is the official tractor testing station for the Organization for Economic Cooperation and Development (OECD) in the United States. This laboratory ...
