Radical Intervention

The aim of the paper was to test the universality of three multi-nutrient soil tests after a radical intervention in soil chemistry by gypsum treatment on a variable set of 36 soils. Pot experiments with barley in a growth chamber were conducted to determine the bioavailability of K, Mg, P, Mn and B from soils. There were no marked differences in correlations between soil tests and the plant in K, Mg and P. But in the case of Mn and B Mehlich 3 test was not in appropriate agreement with the plant. Shortcoming of water extraction is missing information of capacity character for the derivation of the fertilizer recommendations on heterogeneous soils. The highest universality of NH<sub>4</sub>-acetate soil test was proved in all studied nutrients (K, Mg, P, Mn, B) in relation to the plant. Determination of the CEC value that extends the information of capacity character is a part of this soil test. The CEC value contributes to a more sophisticated approach to interpretation for the fertilizer recommendations.

Practical Constraints

Long-standing fertilizer recommendations for field-grown nursery and landscape ornamentals are based on maximizing growth, not nutrient efficiency. Further, these recommendations fall short because of failure to consider 1) the extent of crop nutrient removal, 2) varying nutrient retention characteristics of soils across the United States, and 3) a body of research that suggests that woody ornamentals have a limited response to fertilization under most soil conditions. Concern for the environmental impact of fertilization justifies a reevaluation of current nursery fertilization practices, as well a discussion of the practical constraints on the adoption of new approaches, e.g., nutrient demand-driven fertilization. Research on the nutrient use patterns of woody plants will be reviewed with emphasis on implications for increasing fertilization efficiency. OSU research on water availability and nutrient-use interactions also will be presented.
