Repair Cost of Tractors and Agricultural Machines in Family Farms

Edmund Lorencowicz, Jacek Uziak

Agriculture and Agricultural Science Procedia > 2015 > 7 > C > 152-157

The mechanization cost in agriculture institute between 20% and 30% of the total production cost. The repair cost of agriculture machines is the second important element of the operation cost of the machines. The paper presents problems related to the calculation of the repair costs and analysis of selected family farms in Poland. The paper argues that there is no precise method for the calculation...

Combustion of Plant Biomass Pellets on the Grate of a Low Power Boiler

Artur Kraszkiewicz, Artur Przywara, Magdalena Kachel-Jakubowska, Edmund Lorencowicz

Agriculture and Agricultural Science Procedia > 2015 > 7 > C > 131-138

The study deals with the analysis of results on CO, NO, and SO₂ emission recorded when burning pellets of oil cake, rape straw, and birch sawdust in the low-temperature water boiler of the top combustion. The air was supplied to the boiler through a fan under the grate at a speed of 1 m·s^-1 and 2.5 m·s^-1. There were significantly different emissions of CO, NO and SO₂ under varying conditions of airflow...

Influence of Cellulose Content in Plant Biomass on Selected Qualitative Traits of Pellets

Artur Kraszkiewicz, Magdalena Kachel-Jakubowska, Edmund Lorencowicz, Artur Przywara

Agriculture and Agricultural Science Procedia > 2015 > 7 > C > 125-130

The results from tests for the presence of cellulose in the agricultural biomass waste for selected quality traits of pellets produced were presented. Selected test raw materials revealed the average cellulose content determined by Kürschner-Hanak method in the range from less than 32% (buckwheat straw) to less than 43% (rye straw). There was negative linear relationship between the cellulose content...

Agricultural Use of Biogas Digestate as a Replacement Fertilizers

Milan Koszel, Edmund Lorencowicz

Agriculture and Agricultural Science Procedia > 2015 > 7 > C > 119-124

Functioning of an agricultural biogas plant is connected with generating large amounts of post-digestion matter. After considering the physicochemical properties, the basic direction of digestate utilization should be its use as a fertilizer. A possibility of agricultural utilization of digestate as a fertilizer was investigated. Digestate obtained from an agricultural biogas plant was tested for...
