Data include the start and stop date of simulation provided by the cooperator, latitude, row spacing, plants per row foot, variety planted and emergence date. Planting dates and harvest dates are provided when available. The percent sand and percent clay content are also included for each soil horizon when available. Data include initial ammonia and nitrate concentrations, organic matter content, and moisture content of the soil at 15-cm intervals in the upper one meter of soil. Values of 0 for residual nitrate and ammonia are reinitialized to standard values in the cotton model itself.
Data are for the amount of chemicals applied, the date and the method of applications.
Data include daily values for maximum and minimum temperatures, wind run, rainfall, and solar radiation. Some of the weather files may have headers that indicate their creation date and comments. Tables 1 to 6 are representatives of each of the six preceeding data files, respectively. Dates of occurrences of phenological events and final yield are given when available. Values of -1 denotes no observation for that date.
