TY - JOUR AU - Peterson, M. L. TI - A policy change to more accurate terminology for fertilizers: P and K plant nutrient reporting changes to elemental basis JF - California Agriculture JO - Calif Agr Y1 - 1964/05/01 VL - 18 IS - 5 SP - 15 EP - 15 PB - University of California Agriculture and Nature Resources SN - 0008-0845 UR - http://www.ucanr.edu/sites/calagjournal/archive/?article=ca.v018n05p15 AB - Future publications and other communications of the University of California will report amounts or percentages of a plant nutrient (whether in the plant, in the soil or in a fertilizer) in terms of the chemical element itself. This policy, aimed at simplification and the use of less confusing terminology, follows a similar official change by the American Society of Agronomy and a growing trend in publications of other states as well as within the fertilizer industry.
