Advantages and disadvantages of the ridge plant system, weed control before and at planting and economics of the system are discussed. Ridge planting combines tillage and herbicides to achieve improved weed control in row crops. Crop seed is planted into ridges formed during cultivation and/or ditching of the previous crop. In ridge planting, the planter follows the old row and ridge clearing sweeps or disks move the surface soil, residue and much of the weed seed out of the row. Weed seeds are deposited between the rows where, upon germination, they can be controlled with cultivation. Two cultivations are generally used for weed control. The first cultivation loosens the soil and the second rebuilds the ridge. The ridge plant system is well suited to furrow-irrigationd crops. It also works well with dryland crops or those under center pivot irrigation. On furrow irrigationd land, corn or sorghum stalks may need to be shredded to assist in decomposition and hence irrigation because crop residue slows water advance in the furrow. Slowing the water may be a benefit, however, on soils which have a low water intake rate. With center pivot and dryland acres the need for shredding depends on how much residue the cultivator can handle.
