Shrub rows can be used as needed under the pivot arms. The corners are opportunities for wildlife planting or other harvestable crops. Figure 6 . A and B are dryland sites and C and D are fields under center pivot irrigation. A and B have a twin row windbreak on the field margins where the fall and winter prevailing winds in combination with a series of single row belts perpendicular to most prevalent winds.
B represents an option of planting around a lake or slough area.
Tree planting around wetland and river systems can reduce soil and chemical runoff. C and D show a twin row wind break on the field margins where the summer prevailing winds are present. Shrub rows can be used within the field to extend wind protection and allow spaces for the wheel tracks to pass. Access to fields should be designed downwind from protected areas. Custom Designs Field windbreaks can be designed to fit any size or shape of field or farming operations.
