General Comments: All of the CRVP fields have now reached cut-out (NAWF-5) and are starting to accumulate heat units. The Jefferson County field is the only CRVP field that has not reached the amount of heat units recommended to terminate irrigation (450 hu); however a recommendation for anymore irrigation is being put on hold to see how much rain we may get from TS Issac.
The St. Francis and Lee County fields are ready to be defoliated; however with the threat of bad weather those applications have been put on hold until the storm passes through Arkansas. Hopefully next week more favorable weather will come back into the state.
The following lists the amount heat units that each field has accumulated (as of August 28th) as well as the date of cut-out.
