Variants of mechanized ecological agricultural technologies development by industrial environment-friendly agricultural production system forming are offered.
Some moments of negative influence of irregular fertilizer application on environment and crop capacity are considered in the report. The analysis of engineering process of mineral fertilizer application by centrifugal disperser was made and the reasons of negative influence on the works quality were considered. The description of machines, developed in UE "Belarus Scientific Research Institute...
The competitive products of plant growing and animal breeding cannot be obtained under today's conditions without high-level mechanization. It is necessary to equip the agriculture with efficient and reliable machinery, which would ensure the high-quality performance of technological operations, allow reducing the consumption of fuel and other resources per unit of the products manufactured as well...
The paper provides data on the development of biological farms in Latvia, and characteristics of the factors which enhance and hamper this process. An increase in the number of these farms is prognosticated due to the EU financing. The tasks of agricultural engineering are characterised in this field, as well as several developments at the Ulbroka Research Centre.
In the organic farming the application of herbicides is not allowed and the fertilising is limited to the level of 170 kg nitrogen per hectare. This undoubtedly causes the appropriate decreasing of yields. However if the potatoes yield is concerned there are many other, still not used, possibilities of improvement of agricultural methods and soil tillage, for example by creating the optimal soil structure...
A new construction of a grinder allowing to use air stream more effectively and to make possible management of technological operations practically at all stages of a material stream pass at crushing.
W artykule przedstawiono wyniki badań pracy ciągników rolniczych o mocy 18 i 58 kW (T-25A i MTZ-82) przy zasilaniu paliwem biodiesel (rapso-metylowym esterem RME) i różnymi jego mieszankami z olejem napędowym. Ustalono zużycie czasowe i względne (g/kWh) przy przygotowaniu gleby do siewu z kombinowanym agregatem przy różnych obciążeniach ciągnika i różnych mieszankach paliwowych. Przy pracy ciągnika...
The paper presents an analysis of potato production costs and investigates into possibilities of costs reduction in the farms of the Republic of Belarus.
The technology of recycling of the clarified manure drains by a method of "cold" mechanical evaporation - with ultra dispersion of a liquid on drops of the size 30-80 microns which evaporate under action of atmospheric heat and solar radiation is offered. The design procedure of a monodisperse sprayer such as the rotating punched drum is given (at good wetting a surface of a sprayer by a...
In the article the method of definition of the optimum variant of the mixer-feeder providing distribution of forages depending on the size of a cattle-breeding farm and the distance of transportation of forages is presented.
In the paper presented are results of research of forage crushers and on the basis of theoretical works the conclusion is made about the necessity of creation of a forage grinder providing the crushing and the mixing of forages made in the conditions of large horned livestock farms. The analysis of design of the grinder - HCK-3 and fodder preparation the unit AFIK-IO was carried out. The received...
Herbicide "frontjer" influence on the productivity and technological properties of sugar beat roots is shown in the article. Main parameters of the effectiveness of that preparation application has been defined.
In the paper ecological aspects of liquid manure utilization, its structure after application and effect on environment (soil, water and air) were presented.
This paper describes the results of elaboration microwave moisture meter for continuous control of moisture of sugar and other products in technological processes of their production. Dielectric properties of these materials and technological requirements are determining the choice of investigation methods.
New technologies and means of mechanization of plants protection are briefly considered, allowing to improve quality of treatment of agricultural crops. It is essential to reduce dozes of entering chemical liquid and by that to reduce environmental contamination. The best perspective for today is application of volumetric sprayers, on basis of which principle of action of compulsory delivery of drops...
In article are resulted the developed technique of the parametrical analysis of distribution of loadings in transmission power means with system of pumping of tyres at work with various mounted instruments in structure of the multioperational agricultural unit, the program realizing a technique, and results of alternative calculations on it.
In the article presented is the developed imitating mathematical model for research of dynamic loadings in transmission and smoothness of a motion of the machine-tractor unit on the basis of chassis -with all driving wheels of the hinge-jointed agricultural tractor with the wheel formula 6K6.
