Irrigation characteristics of soils in the Mareeba-Dimbulah area of North Queensland. 4. Infiltration and related data for Nicotine Sand

Abstract

The soil moisture and infiltration characteristics of Nicotine Sand were investigated using techniques described previously. Two dyes (Rhodamine and Fluoresceine) were found useful in defining the "wetted profiles".
The results are discussed in terms of the irrigation amounts, frequencies and techniques suitable for this soil type. It is concluded that frequent light applications using spray irrigation would be required. This soil is of low irrigation potential and its development for tobacco growing would require further investigation.
