Abstract:
The behavior of two herbicides (bromacil and napropamide) applied to a Mediterranean red loam soil (hamra) from a point source is presented. Neither herbicide was degraded during the period of the study. Bromacil was only slightly adsorbed by the soil (Kd - 0.1 ml/g; Fig. 1) and was evenly distributed in the soil volume when applied at a constant concentration (Fig. 3). The distribution of napropamide, which was adsorbed by the soil (Kd - 1.2 ml/g; Fig. 1), was restricted to the zone immediately around the emitter (Fig. 3). Application of the herbicides to previously wetted soils increased the vertical and lateral movement of both herbicides (Fig. 4). Leaching of the chemicals was more pronounced for bromacil than for napropamide (Fig. 5). Cycles of irrigation and evaporation at two irrigation frequencies demonstrated that bromacil can be leached quickly from the emitter zone whereas naproparnide will move only slowly into the soil volume (Fig. 8). © 1981 Springer-Verlag.
