Abstract

Intensification of the dairy industry in southern Idaho has led
to the overapplication of manures and a buildup of soil phosphorus (P),
which is a potential threat to water quality in the region. As the use of
alum has been shown to reduce both soluble manure P and runoff P from
alum-treated manures, the objective of this study was to determine if
surface applications of alum to dairy manure and compost before soil
incorporation would reduce P losses under furrow irrigation on a calcareous
soil. The effects of manure, compost, and fertilizer application
with and without alum treatment on soil P, runoff P, and aluminum under
furrow irrigation, crop yield, tissue P concentrations, and P removal
during a 4-year period were investigated in Kimberly, Idaho, on a
Portneuf silt loam (coarse-silty, mixed superactive, mesic Durinodic
Xeric Haplocalcids). Fertilizer and manure addition had the greatest
potential to increase soluble P in soils compared with compost, which
translated to greater soluble P losses with irrigation in some instances.
The addition of alum to manure did not have any effect on soil extractable
P or soluble P losses from furrow irrigation and therefore,
when surface applied to manure before incorporation, is not a good best
management practice for stabilizing P in manure-treated calcareous soils.
