In-Furrow For A Firm Foundation T. Rhodes Temple Rhodes started applying nutrients in-furrow at time of planting 12 years ago. He didn’t get everything right the first go-round but in the learning years since, he’s certainly become a believer. Last year one of Temple's experiments demonstrated a 2,500 to 3,000 corn plant emergence difference between in-furrow nutrition acres versus non in-furrow treatment. The difference, according to Temple is in the building of the foundation.
