Studies on Water Soluble Boron in Magnesium Rich Saline Alkali Soils of South West Tracts of Bihar

Typical soil profiles from the saline-alkali areas of south west tracts of Bihar were evaluated for water soluble boron and its relation with some of the soil properties. Water soluble boron is present in toxic amount, ranging from 17 to 2.9 ppm. Positive correlations between water soluble boron and electrical conductivity and finer soil fractions have been found to be statistically significant. No significant correlation exists between organic carbon and water soluble boron. A negative nonsignificant correlation exists between exchangeable calcium percentage and water soluble boron but percentages of exchangeable sodium and magnesium have been found to be positively (non-significantly) correlated with water soluble boron.
