1. Soil Testing to Improve Phosphorus Management on Intensive Vegetable Farms in Hawaii According to a recent survey of soil samples sent to the Agricultural Diagnostic Service Center (ADSC) at the University of Hawaii between October 2002 and September 2003, a majority of the samples showed soil test P (STP) levels in the high or excessive categories. Despite high soil test P, many farmers in Hawaii continue to apply P fertilizers. We began a project to evaluate soil P status on a range of vegetable farms throughout the state, to determine crop response to P fertilizers on soils... J. Deenik, S. Fukuda, R. Hamasaki, R.

2. Alfalfa Fertility Survey of Oregon, Washington, and Idaho Understanding alfalfa nutrient status in plants and soils allows researchers and growers identify the greatest nutrient needs for this important crop. A survey of PNW alfalfa fields is being conducted to accurately summarize alfalfa nutrient uptake and biomass yield potential in response to soil agronomic properties to address this question. Forty alfalfa fields throughout alfalfa production regions in Oregon, Washington, and Idaho were selected for the 2022 survey. The number of fields collected... C.H. Messman, A. Moore Download paper
