CODEN: 37MOAO. DOCUMENT TYPE: Conference CA Section: 18 (Animal Nutrition) Urea phosphate (I) [4861-19-2], contg. 17.7% N and 19.6% P, is hydrolyzed more slowly than urea and its N is better utilized by bacterial flora of the gastrointestinal tract of livestock. Cattle given 150 g I/head/day had meat prodn. increases of 10-15% and increased milk prodn. Sheep given 26-40 g I/day had increased wool prodn. I can be easily granulated and incorporated into feeds.

Dynamics of the uptake of trace elements (copper and zinc) in relation to major elements in winter wheat

Dynamics of the uptake of trace elements (copper and zinc) in relation to major elements in winter wheat. Part I. Hudec, Jozef; Polacek, Stefan; Ragas, Adrian (Vys. Sk. Pol'nohospod., Nitra, Czech.). Pol'nohospodarstvo, 24(1), 35-45 (Slovak) 1978. CODEN: POLNAJ. ISSN: 0551-3677. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) The effect of N-P fertilizer forms and N-P-K on wheat uptake of Cu and Zn was studied in pot expts. with a chernozem on loess a soil. The N-P fertilizers were: urea, NH4NO3, urea phosphate [4861-19-2], and (NH4)2HPO4. Urea fertilizer resulted in a greater accumulation of P and less K than did NH4NO3. P-fertilizer form affected P accumulation in wheat organs. Urea phosphate was the most efficient fertilizer. N application resulted in increased accumulation of Zn in all plant parts; P decreased the Zn in straw and increased Cu and Zn in the grain.
