Presented were some research results and forecasts concerning directions of organizational and technical transformations occurring in agriculture and its infrastructure.The main aim of transformations in agricultural enterprises will be acquisi-tion of increasingly safer (healthier) raw materials and food products under con-ditions of better energy and environment efficiency in rural areas. Energy effi-ciency implies decreasing unit material and energy outlays and manpower, therefore decreasing the costs of own products supplied to the market at the prices satisfactory for both producers and consumers.Competitive rivalry on the world food markets decreases and will decrease the number of Polish commodity farms. In the perspective of 15-20 years there will be about 300 thous. of those and they will supply almost all marketable agri-cultural output for processing or directly to the market. All family commodity farms will have to modernize and develop their production on the basis of pre-pared business plan, i.e. a project of equipment, mechanization and investment on farm. Each farm will be able to assess the needs and potential concerning its ad-justment to the requirements posed to future family agricultural enterprises.The paper presents the methodology of farm modernization using techno-logical cards and the way of assessment of investment potential of modernized ...
This paper presents the results of a comparison of the average daily air temperature calculated based on different measurement procedures. Data for the research came from measurements of automatic weather station located at the Research Center of the Faculty of Agriculture and Biotechnology, University of Technology and Life Sciences at approximately 20 km from Bydgoszcz. Series in-cluded data from of the period 2000-2012 with the exception of 2005, 2006 and 2010, due to incomplete series caused by technical service of measuring sensors. Automatic weather station has been programmed for 5-minute sampling intervals, and then the data were stored in the logger memory, as the average of an hour. Hourly air temperature values and the values of maximum and minimum temperatures were used to calculate the average daily air temperature with selected methods. The aim of this study is the evaluation of selected methods for computing average daily temperature in relation to the method that according to the WMO best estimates the daily average (calculated from 24 observation term). Furthermore indirectly determine whether a change in the method may affect the assessment of the current water needs of plants. The research found that the average daily air temperature values calculated ...
At the work a topicality of the methodology of designing forest road networks in mountain areas is being analysed. Adapting individual stages of the design and detailed procedures of the current system of functioning of forest districts in Poland is being discussed, also needs of modern forestry and contemporary design possibilities and the form of initial materials. Using analyses in current studies and processing are being underlined with the GIS processing of data included in the LMN standard. The stage of stocktaking and the location of new roads in net is using well new opportunities of these analyses. The inconsistency of procedures in the stage of determining the optimum density of the road network because of the kind and contents of some-currently available-initial data is being pointed. The stage of the economic appraisal of the planned solution also requires updates because of economic facts change, assumed in analysis of estimated arrangements, as well as using inappropriate sizes incurred costs. The method in its current shape is not used in all, and only some procedures are being involved in thematic studies. New arrangements of criteria of making tree stands available and an indexation of at least some functions ...
