METHOD FOR DIAGNOSIS OF DEMAND IN MICROELEMENT FEEDING OF PLANTS Russian patent published in 2004 - IPC

FIELD: agriculture. SUBSTANCE: method involves growing plants; treating plants with microfertilizers and providing foliar diagnosis; using spatial coherence factor of laser radiation penetrated through leaf and having 630-680 nanometer wavelength; determining microelement deficiency by increase in spatial coherence value and microelement excessive amount by reduction in spatial coherence value as compared to control values. EFFECT: increased precision in evaluating of deficiency or excessive amount of one or another microelement and reduced labor intensity for performing such evaluations. 5 tbl, 2 ex
