Abstract
Abstract Six fields (5 soil types) of corn were treated with soluble boron at different rates and methods of application during 1961 and 1962. A fritted trace element treatment (FTE‐502) was included in 1961, but a lighter application of FTE‐504 in 1962. No boron deficiency symptoms were observed at any growth stage, either on the corn foliage or on the ears. Leaf B concentrations on untreated soil were generally related to soluble soil B. Boron applied either in the corn row or as foliar spray resulted in the highest leaf B concentrations and broadcast B resulted in a lower level. Upper corn leaves sampled in mid‐August were highest in B. Optimum leaf sampling at this time is suggested. These five Minnesota soils, having a water‐soluble B content of 0.33 to 1.58 ppm, apparently do not require B applications for maximum corn production at this time.
