High corn yields require plenty of nutrients and those nutrients must be in balanced supply. Lath-rope Lath-rope declares. For extra bushels that boost prof-' prof-' Its and cut production costs per acre, Lathrope recommends: 1 A soil well stocked with nitrogen, ni-trogen, phosphate and potash. This means adding a starter fertilizer in the row at planting time. It means also supplying the soil with a backlog of nutrients to feed the corn crop all season long. 2 Plenty of active organic matter mat-ter to make the soil mellow and well drained.
