Soil Nutrient Bioavailability: A mechanistic approach, 2nd Ed.
- D. Westermann
- 1 February 1996
Organic Phosphorus Composition and Potential Bioavailability in Semi‐Arid Arable Soils of the Western United States
The organic P composition of semi-arid arable soils is largely unknown, but such information is fundamental to understanding P dynamics in irrigated agriculture. We used solution "P nuclear… Expand
Selection for Drought Resistance in Dry Bean Landraces and Cultivars
- Carlos Germán Muñoz-Perea, H. Terán, R. Allen, J. L. Wright, D. Westermann, S. Singh
- 1 September 2006
Drought is a worldwide constraint to dry bean (Phaseolus vulgaris L.) production. The objective of this research was to determine the response of three dry bean landraces and 13 cultivars evaluated… Expand
Fertilizer applications for correcting micronutrient deficiencies.
Increases in crop yields from application of B, Cu, Fe, Mn, Mo, and/or Zn occur in many parts of the world including numerous regions of the USA. There is growing awareness that micronutrient… Expand
Nutritional requirements of potatoes
- D. Westermann
- American Journal of Potato Research
- 1 July 2005
Plant nutrition is the practice of providing to the plant the right nutrient, in the right amount, in the right place, at the right time. This paper gives an overview of the roles that each of the 16… Expand
Effects of green manures on Verticillium wilt of potato.
Two field studies were conducted to investigate the effects of green manure treatments on Verticillium wilt of potato (cv. Russet Burbank) caused by Verticillium dahliae. Each study involved the use… Expand
Measurement of Atmospheric Ammonia, Methane, and Nitrous Oxide at a Concentrated Dairy Production Facility in Southern Idaho Using Open-Path FTIR Spectrometry
The number of dairy cows in Idaho has increased by approximately 80% in the last decade, with the majority of these facilities located in southern Idaho, causing air quality concerns in this region.… Expand
Colloidal phosphorus in surface runoff and water extracts from semiarid soils of the western United States.
- Benjamin L Turner, Mary A Kay, D. Westermann
- Chemistry, Medicine
- Journal of environmental quality
- 1 July 2004
Colloidal particles in runoff may have an important role in P transfer from soils to waterbodies, but remain poorly understood. We investigated colloidal molybdate-reactive phosphorus (MRP) in… Expand
Nitrogen and potassium fertilization of potatoes: Yield and specific gravity
Potassium and N fertilization is often required for maximum potato (Solanum tuberosum L.) production. Nitrogen, K, and K-sources (KCl, K2SO4 are known to affect yield and quality of potatoes but N… Expand
Specific gravity of Russet Burbank potatoes
Variability in specific gravity of Russet Burbank potatoes was documented in a single 32 hectare field. Maximum variation was 40 units among individual tubers within hills (one unit equals one part… Expand
