I have a field that is about four acres in size. A local farmer has had it planted in clover/ alf alfa the last few years (mostly grass now) He wants to spray it this summer and plant with radishes and clover to help the soil. Next year it would be planted with soy beans. I have 6 apple trees that are 6 to 10 feet in height and about 40 that I have in tubes around the edges of the field. I have no experience with how much the spray would drift and I am worried about the trees getting killed. Any experiences anyone can share. I understand it would depend on windy it is the day of the spraying.
