Fertilization in a Drought
Fertilization needs to happen whether we are in a drought or not. In our region, early spring drought does not necessarily translate into a growing season drought, so planning for a normal crop would be prudent. In addition, crop insurance rules dictate that normal cropping practices need to be maintained.
Although recommendations regarding fertilizer applied with the seed for some crops are similar, pushing rates towards the upper limit when the soil is dry would not be wise, as fertilizer tends to concentrate around the seed when soil dries, whereas if the soil is moist the fertilizer tends to be more disperse.
