Abstract:The SALT computer program may be used to analyze experimentally derived crop salt tolerance response data. The program uses a non-linear least squares inversion method to find the unknown parameters in several salt tolerance response functions. One of three models included in the program is the familiar piecewise linear response function. Application of this function leads to estimates for the salinity threshold and the slope of the response curve. Two alternative types of salinity response functions are also considered.
The program comes with a user manual giving a detailed description of the computer model and the required input data. Application of the program is illustrated with several examples. A listing of the program is also provided.
