Description The CERES crop growth simulation models for
sorghum, maize and mUlet. and other models like SOYGKO and
PNUTGRO are ,becoming widely used for various applications in
agricullure. Thew models use data fllw whose structure was
developed by IBSNAT. As the use of theae models becomes more
widespread the amount of data coded in the IBSNAT format will
become more readily available. There 14 therefore, an advantage in
having an operational, dedicated, soil water balance model
compatible with the XBSNAT data format ao that water balance
analws can be done without reformatting the data. WATERMAN
is a model developed to achieve this objective. The program obtains
the required weather, soil and crop information from the EXP.DIR
and WM.DIR files. All required mil profile variables of the
chosen soil type are then input from the SPROFILE* file. The
user can select several applications, such as dally or periodic soil
water balance, daily water contents of various layers and
irrigation scheduling with or without consideration of rainfall
probabilities Test runs at Samaru. Nigeria, gave acceptable results.
