Abstract
The present investigation was carried out to study the physico-chemical properties of nutrients and irrigation water of BUAT farms. The results indicated that soils of BUAT campus were neutral to moderately alkaline in reaction, non-saline in electrical conductivity, low in organic carbon content, low to high in available phosphorous content, medium to high in exchangeable potassium, low to medium in available sulphur and non-alkaline to sodic content innature.
The soil nutrient index value ofthese soils were low in soil organic carbon content and available sulphur however, it is medium in available phosphorous and high in exchangeable potassium.
pH is positive significantly correlated with BD and available sulphur however it is negative significantly correlated with exchangeable potassium. EC is positive significantly correlated with soil organic carbon. Sodium is positive significantly correlated with BD. Exchangeable potassium and available sulphur is positive significantly correlated with Na.
As far as quality of irrigation water is concerned, the results indicated that irrigation waterof BUAT campus were neutral to moderately alkaline in reaction, safe to manageable safe in electrical conductivity. Sodium, carbonate, bi-carbonate, calcium + magnesium which had been analyzed during the course of investigation are used for the assessment of quality parameter of water VIZ - SAR and RSC. The results invoke that sodium adsorption ratio ranges from low to high and residual sodium carbonate ranges from low to marginal.
The irrigation water shows that pH is negative significantly correlated with SAR. EC is also negative significantly correlated with SAR. The carbonate content of irrigation water is found to be positive significantly correlated with calcium and magnesium. The sodium content had also been found to give positive correlation with SAR.
It had also been evaluated that the impact of irrigation water on the soil shows that EC, sodium content and SAR have major impact on the fertility status of soil. Overall, BUAT farms required immediate attention for the improvement of soil fertility and management of natural resource for improvement of crop productivity.
