Mowing of grasses and bush vegetation appear one of the most important technological operations while exploitation the roads, dams and ameliorative channels. For such activity agricultural or ameliorative multi-rotor mowers with joint knives are used. Multi-rotor mowers are characterized with high productivity and reliability along with complete cutting ability. Parameters of cutting devices are analyzed according the peculiarities of reclaimed land (among the peculiarities there are outlined unevenness and inclination of the relief).
In the conditions of the Republic of Belarus there was analyzed a problem of economic basing of optimal functioning of melioration system taking into account planning of agricultural production and reproduction of water-and-land resources during the given period. There were presented methods of basing of initial information for the suggested economic-mathematical model.
A distinguishing characteristic of Belarus is the presence of boggy territories and abundant humidification of the land. Natural and climatic conditions permanently influence on the agricultural producing process of the republic. Most of the waterlogged lands have been undeveloped for a long time. The first land reclamation arrangements have been made in XVII century. With the course of time ameliorative works becomes more and more intensive. The role of the Gory-Goretskaya agronomic school, future Belarus State Academy of Agriculture in the amelioration process establishing is evaluated.
Amelioration is one of the most important factors of agricultural production intensification and scientific and technical progress implementation. One third of agricultural production of the Republic of Belarus is produced on reclaimed lands. Closed horizontal drainage is the most wide-spread method of regulation of water and air regimes of soils in the conditions of intensive agriculture of the state. Successful application of drain-installing machines supplies increase of labor productivity, improvement of amelioration works and agricultural crops productivity increase.
The aim of the research is to investigate the impact of complex land reclamation including chemical reclamation, manure applying, and ameliorative tillage on physical and chemical properties of chernozem solonetz. The study was carried out in the Rostov region at two backgrounds: 1 – ameliorative tillage by three-tier plow: 2 – ameliorative tillage by plow-milling tool.
The integrated method of dark-chestnut soil reclamation comprising green manure and application of different doses of phosphogipsum and mineral fertilizers (MF) calculated for planned yield was used in 2009. Influence of this actions on physical, chemical, agrochemical properties of soils upon rice growing, as well as on the yield of rice and winter wheat have been estimated during three following years. The variant "green manure +10 t/ha (double dose) of phosphogipsum + deep subsoiling + MF" had the best impact on soil processes.
Necessity of the increment of the milk and meat production along with other agricultural products has caused the need to engage in an intensive agricultural use of new land, including flood areas that have been drained through the construction of polder systems. A total number of protective systems, fencing drained land from the influx of surface water compose over 3,900 miles of dikes. Nowadays reclaimed lands compose more than 220 hectares, equipped with polder system with mechanical water lift.
The objective of researches was approbation of concept of the recreational biogeosystem engineering by example of phosphogypsum recycling in soil upon simultaneously rotary ameliorative tillage in the soil layer from 30 to 60 cm. The research methods were stationary, field, laboratory, computed and thermodynamic which allows evaluating the extent of sustainability of the new phosphogypsum recycling biogeosystem in chernozem. The applying of proposed concept resulted in the improvement of morphologic soil structure, the increasing of depth and uniformity of sunflower root distribution.
Soil change at management of its dispersed system by means of three-tier and rotor-milling tillage is studied. After single soil-meliorative rotor-milling plowing the processed soil layer consists of small units homogeneous for the size. There are no morphological signs of a solonetz pedogenesis restoration. The moisture of an atmospheric precipitation freely penetrates into the soil and easily distributes in artificial dispersed system. Readily soluble salts leach off to depth, sufficient for reducing of their influence on soil genesis.
