Furrow irrigation detaches and transports soil particles and subsequently nutrients such as phosphorus. To reduce the risk of erosion and offsite phosphorus movement, producers can convert from furrow to sprinkler irrigation. We completed research on soil phosphorus dynamics in furrow versus sprinkler irrigated soils from four paired fields in south central Idaho. Surface soils (0-2.5 inches) were obtained from fields in the fall following harvest. Furrow irrigated soils contained 38 parts per million of plant-available phosphorus (i.e. Olsen-extractable) on average, as compared to 20 parts per million under sprinkler irrigation. These results are important as 20 parts per million Olsen-extractable phosphorus may be considered the concentration where... |
