Abstract

Obtaining adequate and uniform stands of small seeded
crops is often a serious problem on soils susceptible to
crusting. A study was conducted to determine if spraying
dilute phosphoric acid in narrow bands along the seeded
rows would increase sugar beet (Beta vulgaris L.) seedling
emergence by preventing or minimizing soil crusting and
provide the needed nutritional P for crop production.
Dilute phosphoric acid was sprayed along rows seeded to
sugar beets on a Portneuf silt loam. Several acid concentrations
and P rates were applied. Stand counts were
made before and after thinning, and P concentrations
were measured in sugar beet petioles sampled at three
dates during the growing season. Laboratory studies were
conducted to determine the effects of the phosphoric add
on soil properties.
