Abstract:
Working organs being used currently for subsurface tillage do not comply with agrotechnical requirements. In particular, the crumbling of soil layer is unequal across the width of cutting plane of working organ. The scientific hypothesis is that variable cutting angle along the length of blade improves the crumbling of soil layer. The mathematical model of interaction between the soil and a wedge is proposed. As the result, the theoretical dependencies of resistance force of soil to destruction and of thickness of shear layer on the setting angle of tillage tool are obtained. A set of dihedral

Abstract:
A-hoe blades consisting of a share and a frog are used as working organs of cultivators. Main characteristics of share are the expansion angle of blades and the crumbling angle. For falling away of cut weed, the expansion angle should not exceed 70 degrees. The higher crumbling angle provides more intensive effect on the soil. There are also negative effects in working process: soil displacement aside, formation of grooves, removal of moist soil to the daylight surface. As far as copying elements of cultivator are separated by a distance from working organs, the variability of operating depth

Abstract:
Abstract Layer-by-layer loosening of soil contributes to an increase in energy consumption for its cultivation. Thus, in order to reduce traction resistance, a blade with a variable crumbling angle has been developed. In the blade stand area, it is proposed to increase crumbling angle of the chisel plow by analogy with working bodies of the chisel plow to 300, and the blade wing should be made in the form of a flat-cutting blade with a small crumbling angle. To substantiate paw profile in the strut zone, a static equation of action of forces has been drawn up depending on curve shape of the fr

The paper gives justification of the options of the housing with crumbling knives for non-tillage technology. The dumpless housing with crumbles carries out intensive crumbling of the soil of the lower and middle arable soil layer. The body consists of a ploughshare, a ploughshare expander, knives and a chisel. When determining the parameters of a non-shaft housing based on a ploughshare, adopt a triangular wedge. Analytical dependences for determining the parameters of the components body without shaft are obtained. According conducted theoretical studies, without a tipper is 0. 45 m, entry a

Abstract:
Due to ongoing climate change, the demand for water in agriculture is increasing annually, while water scarcity becomes more pronounced. Therefore, every drop of water must be efficiently conserved. Mineral nutrients are applied to improve the reclamation status of saline and gypsiferous soils before leaching them. However, these nutrients often do not reach the root layer of plants. To address this issue, we conducted a study to determine the optimal opening angle of the winged blades in the fertilizer system of a chisel-cultivator.

Abstract:
Today, the issues of ecology, resource conservation and reduction of production costs in agriculture are associated with the development of combined tillage - sowing machines, which make it possible to reduce a number of technological techniques. Taking into account these factors makes it possible to equip agricultural enterprises with means of mechanization adapted to the specific conditions of their production use. Therefore, a promising direction is the development of universal and combined machines, that is, technical means of mechanization capable of performing several technological opera

Abstract:
In conditions of increasing production and turnover of agricultural crops, soil degradation associated with wind and water erosion leads to depletion of fertile land and reduction of crop yields. One of the ways to increase the protective capacity of cultivated areas is deep loosening. The development of methods for assessing the efficiency and forecasting the use of tillage elements, taking into account economic, qualitative and agrotechnical requirements is an urgent task. To provide for the rational choice of a tillage element, the authors compared commercially produced domestic and foreign

Abstract:
This chapter argues that Molly Keane’s heretical late novels violate every possible standard of good behaviour, especially in their scandalous emphasis on the unsavoury aspects of eating and excreting. Mesmerised by these nauseating details, critics have tended to overlook Keane’s affirmation of the pleasures of food and its redemptive value for her Anglo-Irish heroines, trapped as they are in the crumbling Big Houses of the moribund Protestant Ascendancy. Keane insists on the uncomfortably close relationship between the grotesque and the delicious in a context where denial of physical pleasur

It discusses the decline of the Anglo-Irish aristocracy during this period, and how this decline is readily symbolised by vanished or crumbling Irish country house architecture. The chapter traces this decline through early twentieth-century revolutionary sentiment as mass organisations such as the Irish National Land League caused further anti-landlord sentiment, and the political developments of the period further undermined the power of the gentry.

Frightened by potential anarchy, moderates looked for a way to bring the opposition into dialogue with the Modrow cabinet.
