Anaerobic co-digestion of oil refinery wastewater and chicken manure to produce biogas, and kinetic parameters determination in batch reactors
(2017)In order to improve the anaerobic fermentation of oil refinery wastewater (ORWW) via an appropriate nutrients pool for microbial and buffer capacity growth, a study was carried out on related anaerobic co-digestion (AcoD) ... -
Theoretical research into the stability of motion of the ploughing tractor-implement unit operating on the ‘push-pull’ principle
(2017)The reduction of power consumption in the ploughing operations can be achieved by way of improving the grip properties of the implement-carrying tractors, which is facilitated by setting up ploughing units for operation ... -
The assessment of hazelnut mechanical harvesting productivity
(2017)Hazelnut cultivation represents a new opportunity for Calabrian mountainous and sloping areas (Southern Italy), where no alternative fruit crops, except forestry, could be settled. In this Region, hazelnut production ... -
Reed canary grass cultivation’s energy efficiency and fuel quality
(2017)The article discusses the energy yield and yield capacity of reed canary grass stands in semi-natural and cultivated meadows with edaphic conditions most favourable for species growing on fertile soil. Energy grass ... -
Theoretical research into the motion of combined fertilising and sowing tractor-implement unit
(2017)A mathematical model has been developed representing the motion of a seed drill combination simultaneously performing the preceding banded placement of mineral fertilisers. Such a combined unit comprises the gang-up ... -
Effect of controlled traffic farming on weed occurrence
(2017)Soil compaction caused by field traffic is one of the most important yield limiting factors. Moreover, published results report that soil over-compaction inhibits the uptake of plant nutrients and decreases their ability ... -
Effect of rake angle and cutting speed on energy demands of mulcher with vertical axis of rotation
(2017)The contribution deals with the reduction of agriculture energy demands. For maintenance and treatment of permanent grassland areas, areas left fallow and put to rest the mulching in combination with other workflows ... -
Investigations about the impact of the sowing time and rate of the biomass yield and quality of industrial hemp
(2017)The aim of this study was to find the optimum sowing rate of industrial hemp (Cannabis sativa L.) and to clarify the impact of the sowing rate on the production of biofuel from hemp biomass in Latvia. Field trials were ... -
Influence of shape of cutting tool on pressure conditions in workspace of mulcher with vertical axis of rotation
(2017)Nowadays there is laid great insistence on work efficiency improvement. This effort also affects the construction of mowers such as mulchers. Mulching with a vertical axis of rotation is very energy demanding work operation ... -
