Fact Sheet

Animal manures have been used as natural crop fertilizers for centuries. Because of poultry manure’s high nitrogen content, it has long been recognized as one of the most desirable manures. Besides fertilizing crops, manures also supply other essential plant nutrients and serve as a soil amendment by adding organic matter, which helps improve the soil’s moisture and nutrient retention. Organic matter persistence will vary with temperature, drainage, rainfall, and other environmental factors. This 2-page fact sheet was written by Michael A. Davis, D.R. Sloan, Gerald Kidder, and R.D.

The results of a syntaxonomical study of plant communities of the large lake Donty (North-East of the European part of Russia) are presented. The diversity of hydrophytic vegetation has been classified into 3 classes (Lemnetea, Potametea and Phragmito-Magnocaricetea), 5 orders, 8 alliances, 20 associations and 1 community. Subasso­ciation Scolochloetum festucaceae caricetosum aquatilis is new. Communities of associations Caricetum aquatilis, Equisetetum fluviatilis, Potamo—Nupharetum luteae, Potametum perfo­liati are mostly wide distributed, while these of Phragmitetum communis, Scolochloetum festucaceae ones are relatively rare as well as Lemno—Spirodeletum polyrchizae, Elodeo—Potametum alpini, Potamo—Nupharetum pumilae, Potametum praelongi and Scirpetum lacustris are very rare. Some communities contain 2 regional rare species: Scolochloa festucacea and Ranunculus lingua.

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.
