Nitrate determination in sugar beet sap extracted with lead acetate 2 lead monoxide using an ion selective electrode


, : Nitrate determination in sugar beet sap extracted with lead acetate 2 lead monoxide using an ion selective electrode. Communications in Soil Science & Plant Analysis 22(5-6): 589-596

Nitrates were directly determined in sugar beet sap, extracted with 0.04 M Pb (CH3COO)2-0.002 M PbO, using an ion-selective electrode. Nitrate levels as low as 5 mg/kg of fresh plant weight could be accurately determined with a high degree of precision. As an additional advantage, this method can be automated so that nitrates in sugar beet sap can be determined simultaneously with Na, K, aminoacid-nitrogen, and sugar.

Do-it-yourself artificial insemination (DIYAI) of cattle is now a common practice on dairy farms, and, if used properly, is a cost-effective fertility management tool. However, there is much potential for DIYAI to contribute to poor fertility rate...
