Nitrous Oxide and Carbon Dioxide Concentration in Farrowing Pens with Permanent Limited Range of Motion for Lactating Sows
Nitrous oxide (N2O) and carbon dioxide (CO2) are two of the most important gases causing global warming. Production of mentioned gases is pig housing considerable. The aim of the paper was a comparison of the N2O and CO2 ... -
Investigating Machinery Management Parameters with Computer Tools
Engineering tools have been effective in demonstrating the parameter impacts on machinery systems. This paper shows four class exercises and discusses the parameter influences and decision-making for the examples. These ... -
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 ... -
Biogas Yield from Anaerobic Batch Co-Digestion of Sisal Pulp and Zebu Dung
Co-digestion of various materials has been shown to improve the digestability of the materials and biogas yield. The degradation and biogas production potential of sisal pulp could be significantly increased by co-fermenation ... -
Machinery Productivity Estimates from Seed Tenders
Several methods and machines have been introduced during the last five years that can improve the timeliness and productivity of planting operations. Several manufacturers claim these devices can increase productivity by ... -
A Comparison of the Field and Laboratory Methods of Measuring CO2 Emissions Released from Soil to the Atmosphere
In the context of global climate changes the attention of the research is focused on the soil tillage technologies. Soil tillage significantly affects the amount of carbon dioxide (CO2) released from soil to the atmosphere. ... -
Ecology and Work Quality of Fan Flat Nozzles
Working parameters of fan flat nozzles which affect drop tracks size were the subject of the study. New nozzles and nozzles after laboratory wear were tested. The influence of nozzles wear on drop tracks size were examined. ... -
The Fractal Dimension of Agricultural Parcels Considering Maize Yield
Before making any decisions, all farm managers would like to have some indication about the effectiveness of a particular investment, especially when investing in precision agriculture technologies. Usually, the best ... -
Mechanisation and Logistical Cost of the Field Vegetable Production Technologies
The economic investigation of field vegetable production is introduced by using the production technology of the most important vegetables: sweet corn, green peas, onion, tomato, carrot and cucumber as examples. The paper ... -
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 ... -
