Tkalych V. The agroecological substation of crop rotation in soil hothouses and conservatoires

The thesis highlights the concept related to the evolution of the soil - plant system under the conditions of the artificial climate. It haes been estabhihed that in comparison with field conditions the system evolution is accompanied with the formation of the active microbiological complex which includes fungi, bacteria and actinomycetes. Consideration is given to the theoretical substantiation and practical implementation of the possibility of managing the agrochemical and microbiological state of soil in hothouses and conservatories through introducing crop rotation in them. It has been shown that developing crop rotation in these objects without electric power expenditures for maintaining light and temperature condition of growing contributes to the considerable improvement of the biological level of soil fertility. It has been established that cultivation of vegetable, medicinal and tropical crops in soil hothouses and conservatories when they are free from grain ear crops contributes to obtaining ecologically safe produce as well as to improving soil fertility.
