Analysis by Prompt Gamma-Ray Method with Cold Neutrons of Boron and Other Elements in Soybean well as root samples were dried, prepared as thin disks and irradiated with cold neutrons. Prompt gamma-rays emitted from the sample was measured by Ge and bismuth germanate (BGO) detectors. Boron content in root was less than 40% of that in leaves. The same sample was used to determine Al, K, Ca,

Total boron determination in silicate material with azomethine-H, after extraction with boron specifmple fusion with sodium carbonate, the melt is dissolved with water and B is extracted from the aqueous phase with a B specific resin, Amberlite IRA-743. Boron is then eluted from the resin with hydrochloric acid and colorimetrically determined with azomethine-H. The preliminary results, using three

An improved procedure for the extraction of plant available soil boron. soluble soil boron(B). The oven temperature for extraction was 100° C, the orbital shaking speed was 250 revolutions per minute (rpm) and the extraction time was 30 minutes. Control of the extraction temperature and time with minimal evaporative loss of water achieved adequate precision (C.V. = 0.
