Abstract:
Knowledge of different fractions and availability of boron (B) is essential while studying the response of crops to B. Fractionation provides information about the chemistry of B and quantifies its bioavailability. Such information is potentially valuable for predicting bioavailability, B leaching, dynamics, transformation between chemical forms in soils and environmental impacts. A total of thirty number of soil sample from thirty different village of Imphal-West District were collected and analyzed in the laboratory to study the correlation between various fractions of boron with various soil physico-chemical properties. From the correlation studies, it can be seen that boron had a positive and significant relationship with soil pH, soil organic matter, soil cation exchange capacity (CEC), silt and clay content of the soil. Whereas, soil electrical conductivity (EC) and the sand content of the soil showed a negative relationship with different fractions of boron. Positive and significant relationships were found between the different fractions of boron except oxide bound boron which showed negative correlation with residual boron however non-significant. This proved that all the fractions of boron are interrelated and exist in an equilibrium state within the soil.
