I meant that I think it is less mobile than some people credit. It cannot be available for the crop until washed into the soil, which probably needs the first 1/2 inch of rain to achieve, the next inch will not cause any problems, particularly from the dry position we are now in. It will probably then dry up again mid March for a month, if it rains again then, I shall put a second dose on. I cannot see an early application being too wrong, I have regretted not getting it on far more often than having done it.
