Analysis of the Levels of Phosphates, Nitrates and Sulfates in the Wheat Growing Area of Ntulele in Narok County, Kenya

Abstract

This study sampled wheat farms in Ntulele area of Narok county to determine the levels of nitrate, phosphate and sulfate using UV-VIS spectrophotometer and data analyzed using MSTAT-C, SPSS and student t-test. Nitrates were found to be sufficient whereas phosphates and sulfates were found to be deficient in most of the farms sampled. Sulfate had the least CV% of 8.54 followed by nitrates with 14.23% and phosphate had the highest with 21.91% an indication that all the nutrients were applied in similar rates by the farmers of Ntulele. The nutrients before and after planting were significant (p<0.05).
