A comparative analysis of milk production in Poland and Belarus was carried out. The basic tendencies of modern development of the dairy industry and offered upcoming trends of innovative modernization of milk production processes were analyzed. On the basis of the analysis of trends in the global production of milk and new scientific knowledge on the biosynthesis of milk, a conceptual approach to the design of equipment for machine milking, is provided, considered the relationship of technical and physiological parameters.

The study evaluates granulated coffee grounds use as an additive to soil. Specific physico-chemical and functional properties of soil that enable assessment of its fertility and that have a possible impact on plants growth and development were analysed. The research proved that granulated coffee grounds added to soil increase sorption properties and decrease pH of the soil solution. Moreover, the increase of the phenol compounds that decreased the germination ability and reduced the length of roots of a test plant, namely winter wheat, was reported.
The continuous technological development requires the use of modern materials also in agricultural engineering. Knowledge of the characteristics of tribological materials pairs cooperating with each other is useful for developing sliding nodes of agricultural machinery. Tribological properties of materials should be assessed for selection of technological materials beyond the economic criterion. The article presents analysis of the characteristics of tribological ball-on-disc wear of polymeric materials used as sliding elements for farm machines. Tribological tests were carried out under dry friction for a polymer-metal pair, and a wear rate and friction coefficient of the sample; the signs of wear were submitted to SEM observations.
The most time consuming and the least mechanized process of potato cultivation is its harvesting. Therefore, now, as never before, we have faced a problem concerning the improvement of the existing and construction of new devices for potato harvesting and their provision to the cultivation industry. It requires further development of theoretical, complex and extensive research on the phenomenon of separation of the potato stack, which will enable justification of optimal work modes of the existing separating devices and will be used for the synthesis of basically new, more advanced separators

Dairy cows production plays a significant role in development of Podkarpackie Voivodeship. Progress in this production branch may depend on the dairy production support which is given after relevant types of actions are undertaken. The objective of the research was to determine changes in the level of welfare of production animals, evaluation of practice in dairy cows breeding in the province of Ropczyce and Sędziszów. Breeding documentation and control protocols of the Coordinated Veterinary Inspection Program were applied pursuant to the resolution (1) of the Minister of Agriculture and Rural Development of 28 June 2010 on minimal conditions of maintaining farm animal species. 10 production herds of dairy cows (n-240) and heifers (n=101) which produce ≥ 10200 kilo of milk per lactation were used to achieve this objective. Dairy production was observed during individual visits in farms. Surveys were carried out with farm employees with the use of properly prepared veterinary control protocols of the Coordinated Veterinary Inspection Program. Control results were obtained based on the respondents' opinion from controlling institutions, such as: The Agency for Restructuring and Modernization of Agriculture, Regional Veterinary Office and similar certified bodies.
The paper analyses technical equipment of the selected dairy farms. Data from questionnaires carried out in 96 farms in 2015 constituted a research material. Municipalities Lszewo-Borki in Mazowieckie Voivodeship were covered by the survey. A survey questionnaire, which consisted of two parts, was a research instrument. The first concerned general information on a farm and its owner, and the other consisted of eight questions on technical equipment used for breeding dairy cows. The research allowed to determine that farmers assessed the condition of their machinery park as average (50%) or good (40%). One out of ten farmers claimed that the used machinery park in a farm is in a bad condition. Majority of respondents have allotted from PLN 20 to 50 thousand for investments related to enhancement of a machinery park within the last 5 years. On the other hand, a considerable part of farms allotted up to PLN 20 thousand for development of a machinery park. The investigated group included also farms, which allotted more than PLN 500 thousand for development of a park.
Comparative analyses in the national scale were carried out in 300 individual farms from Małopolskie and Świętokrzyskie Voivodeship in order to search for relations between the production intensity level, work performance and land efficiency and factors which shape them. The analyses concerned the use of Bayesian modelling algorithms for forecasting development of various economic and agricultural indicators which decide on the intensity and competitiveness of agriculture. The paper constitutes the second stage of research, which was preceded with previous preparation of data for modelling with the use of an exploratory overview of available data and TwoStep Cluster Analysis (Grotkiewicz et al., 2016). Based on the analyses, which were carried out, networks were built which present the relations between the analyzed variables, and conditional similarities were verified.
