Occupational accidents in agriculture are a problem all over the world. The costs of accidents are high to the employer and to the national economy as a whole. Work-related ill-health and injury is costing the European Union 3.3% of its GDP. In Estonia, the estimates of the costs of work accidents (WA) in 2012 showed €2.4 billion per year and due to permanent lost workability €25 billion costs ...

Technical, economic, and social need to define and control the efficiency of energy usage – consumer energy efficiency implies the necessity to determine the exact contents of this new concept. A deeper analysis of a consumer energy system in order to support the consumer energy efficiency value appropriate for the contents should be carried out to find the factors that affect the value. This ...

The purpose was to assess the effect of silicon on the leaf lettuce production. The experiments in the greenhouse were carried out in the spring 2014 at the Estonian Crop Research Institute. Treatments: 1) stabilized silicic acid treatment; 2) control. Si treatment (2 mL L–1 of silicic acid): First spray, when 1 true leaf was present; second spray was two weeks after spray 1; third spray was t ...

Improving the adoption of improved crop varieties is very important to increase income, reduce hunger, sustain food security, and to reduce poverty in sub-Saharan Africa like Ethiopia. Similarly, Belete potato variety is one of the improved varieties that have been utilized by Ethiopian farmers, but this variety was not conjointly adopted in all parts of the country. Thus, this research was in ...

Vermicomposting is described as "bioxidation and stabili¬zation of organic material involving the joint action of earthworms and mesophilic micro-organisms". Under appropriate conditions, worms eat agricultural waste and reduce the volume by 40 to 60%. Vermicompost produced by the activity of earthworms is rich in macro and micro¬nutrients, vitamins, growth hormones, enzymes such as proteases, ...

Human-centred evaluation of technology and work techniques requires the determination of the workload category and the internal workload, which is the internal response of the worker to exposure to external load factors in the work environment. The aim of this paper is to present a method for a human-centred analysis of the work process. The method requires the worker's physiological data, whi ...

The correct selection of the level of mechanical ballasting for wheeled tractors is among the most important issues for increasing their utilisation efficiency, in particular, increasing their grip properties. The shortcoming of the earlier undertaken investigations was that they virtually did not take into account the allowed maximum pressure of the tractor's wheels on the soil. At the same t ...

The algorithm for estimating engineering solutions at the design stage in terms of the relative energy intensity by the method of finite relations (MFR) has been considered. The description and diagram of an energy consumption system serving as the base object in the analysis of energy efficiency for the manufacturing of products have been given. The basic features of using the method of finit ...
