Abstract:
Some information on soil, water, salinity and plant relations needs to be collected and processed at laboratory level before shifting to the fields. Pot culture studies in that context have often been useful in estimating the importance of different types of salinity with different caution and anions concentration. The present paper focuses on some mathematical manipulations for developing synthetic soil and water salinity levels. Use of quadratic equation and checkerboard exercise has been promoted to complement the traditional salinity calculations. Quadratic equation and checkerboard exercise can be effectively used in developing synthetic brackish waters of different CA: Mg rations under some predetermined EC and SAR limits. Water having different RSC levels under the same EC, SAR, Na and Ca + Mg status can also be prepared by adjusting the relative proportion of CO3 + HCO3 anions in the calculations. Similarly, soils with different salinity levels or soils with the same salinity magnitude but with different percentages of major cations and anions can also be developed. Manipulation of such calculations is often helpful in strategic planning of saline culture studies for monitoring and establishing specific ion-effect and crop stress relations.
