The assessment of agrotechnical factors of barley cultivation on resource-saving technologies by means of land spectrometry

Optimization of agrotechnical methods of field crops cultivation is possible with the application of remote sensing. For this purpose in the conditions of Krasnoyarsk forest-steppe the researches on the assessment of dynamics of increase of elevated phytomass of barley during vegetative period with application of classical method of accounting of crop and ground-based spectrometry were conducted. Distinctive features of growing season, which should be characterized as unfavorable for the cultivation of grain crops, include increased heat supply in June and August and extremely low rainfall during June, July and August. During sowing period (in May), moisture supplies in a meter layer of the soil of the samples were good (172.7-195.8 mm). During barley flowering period the moisture supply available in a meter layer of the soil was reduced to the minimum during the whole vegetation period level and amounted to 19.0 mm and 26.9 mm. It had a negative impact on the size of barley phytomass...
