Abstract
The feasibility of Ca reduction analysis of soil nitrate as a teaching method and also as a general soil nitrate analysis method was determined. Soil samples (16) were analyzed for nitrate using Cd reduction, phenoldisulfonic acid and steam distillation methods. The soil pH levels ranged 6.3-8.4. The nitrate levels ranged 1-62 ppm, the soil nitrite levels 0.3-2.6 ppm. Correlation coefficients between the 3 methods were highly significant. The analysis means were statistically the same between the Cd reduction method and steam distillation methods. The analysis of soil nitrate by Cd reduction was acceptable for the determination of soil nitrate levels.This publication has 3 references indexed in Scilit:
