Synopsis

Excerpt from Research Note: Rm 151-227

The failure of the soils from the three sites to reach the same level of productivity might mean that tests of different rates of application would be in order. It is entirely possible, however, that other inherent soil factors, such as those connected with the moisture regime, may be involved. Hints of this effect were observed in the greenhouse in the differential rates of drying among the three soils.

Nevertheless, it appears that fertilization of soils on Black Mesa will be effective in increasing herb age yields. Field testing and cost-benefit studies are needed, however, as the first step toward a management program in this field.
