The necessity of liming strongly acid soils that will be planted in corn is well illustrated in a demonstration conducted by Harold Vaught, Area Extension Agent in Adair County.
A field that was well fertilized with nitrogen, phosphorus, and potassium produced low corn yields in 1966. Analysis of a soil sample from the field showed that it was strongly acid soil. (Similar conditions have been reported by many farmers throughout the state in recent years.) Since this field was to be planted in corn again in 1967, a liming demonstration was planned .
