ADVANCED METHOD OF AGROCHEMICAL STUDY OF SOILS |
摘要 |
FIELD: agriculture, agrochemical mapping of arable lands. SUBSTANCE: advanced method of agrochemical study of soils includes isolation of contours by results or remote probing of fields with open (ploughed ) soil on processed radar aerospace pictures and translation of contours on land-tenure maps. Elementary sections for selection of specimens on paper carriers and on land are isolated with the aid of contours. Contours are exposed with the use of reflected signal of side-looking radar of decimeter range of wave length and on basis of factor of curvilinear correlation that is determined by ratio of value of reflected signal of radar to agrochemical indices which are used to evaluate soil fertility. EFFECT: improved authenticity of method. 1 cl, 2 dwg, 1 tblo
