Layerdepthin cmreclaimed soils are deprived of valuable agronomic structures of natural soils,which are created by decades. Until then it must be performed by soil treatment.Due to heavy mechanical composition, clays are susceptible to compaction and thevolume of the bulk density of the soil substrates is too high. The soil treatmentsreduce these values, but for more permanent loosening a period of several years isneeded.Improving the structure of soil substrates also leads to lower values of thebulk density. It was observed a trend for soil loosening in introducing siderate cropresidues and including gypsum from SCI.In the past 10-15 years a big problem, attended biological reclamation isrelatively intensive climate aridization, which leads to inability of successfullygrowing of a number of traditional for the area spring crops. Table 1 shows data ofsoil water reserves for the three years of test conducting on the technology fornonhumus reclamation. Except for 2002 the summer droughts are quite perceptive,in 2000 for the months July and August there is no receipt of rainfall water, as thewater reserve in 0-80 cm layer is about 1.5 times smaller than that in May 2002(Table 1).96Table 1.

Prolonged summer drought many years upset thesunflower crop, which is considered as a drought resistant crop. It is necessary tostudy the possibilities for growing profitable crops which to be included in sowingcirculationwith winter cereal crop growing almost as a monoculture. Such cropsare coriander, rape, winter pea, chickpeas, etc. They use autumn-winter soilmoisture reserves and ensure sustainable production.
The analysis made of the conditions of conducting the reclamation foragricultural purposes in the region of "Maritsa Iztok" and the prospects for itssuccessful development through nonhumus ways ascertained that:- There are many problems, the most significant is the importance oftheir climatic and technological nature.- - It is advisable to make adjustments in the technological operations intechnical and biological reclamation. To develop a specific system offarming for biological reclamation purposes by growing siderate crops,species and variety structure of field crops, consistent with the changedclimatic conditions and criteria for the maintenance of the parametersof soil substrates in optimal limits according to the requirements of theoccupational cultures.- - Any agro-ameliorative event unsuitable for the specific conditionsleads to the risk of failure of the whole technology of disturbed landreclamation of the land disturbed by the open coal mining in “Maritza-Iztok" area.REFERENCES:1.
