Climate change is causing problems for farmers almost throughout Europe, particularly in the area of soil drought. The current soil situation in Slovakia and Europe is not favourable. Declining cattle numbers are causing a shortage of organic fertiliser, soil degradation is occurring, as is soil compaction with high weight agricultural machinery causing changes in the bulk density of the soil and its penetrometric resistance. The aim of this paper is to point out the possibilities of prevention against soil degradation. In this paper we compare the effect of conventional technology and soil conservation technology in combination with soil biostimulation on the change of soil condition.

Post-harvest grain treatment is today one of the key processes taking place in agriculture-oriented farms. Only cereals deprived of unwanted impurities, dirts and excess water can be optimally stored and later monetized at the highest possible price. It is the reduction of the water content in the grains that is the key factor in their preservation, as the biochemical and bacterial processes will be interrupted, thanks to which the grains can be stored for a long time.
The paper deals with the technical characteristics of the grain dryer Chief CBS 14-6 in the process of drying corn grain in specific conditions in Slovakia, compares various energy sources such as natural gas and waste straw from agricultural production.

Field experimental studies of a new beet tops harvesting machine, which is front mounted on a wheeled tractor aggregating tractor, are carried out, carrying out a continuous non-sensing cut of the green massif of sugar beet tops. At the same time, a new laboratory-field installation was developed, which consists of a rotor type front mounted rotary type machine with a horizontal axis of rotation, a transverse screw for collecting the cutted leaves from all width, and a loading mechanism in the form of a paddlewheel and a loading nozzle. During the field experiments, the tractor moving with a specified speed regime fixed by track measuring wheel, the total cutting height was set in a predetermined interval by means of two pneumatic sensing wheels with adjustment mechanisms. The rotational speed of the rotary cutter, with arched knives mounted on the drive horizontal drum, was varied with the help of replacement asterisks. In the prepared area of sugar beet field, the beet tops was cut at various parameters of the harvesting process, which was then estimated by the size of the remaining tops remnants left on root crops heads and in the aisles. According to the developed program and methodology, statistical processing of the results of experimental studies with the help of a personal computer was subsequently carried out, which allowed obtaining graphical dependencies of the indicated tops residues on the root crops heads, which made it possible to establish performance of new harvesting machine for continuous cutting of sugar beet tops. The established dependencies made it possible to choose rational constructive and technological parameters for harvesting tops by front mounted harvesting machine.
