"The agricultural drainage study was conducted under the direction of: Robert J. Pafford, Paul De Falco [and] John R. Teerink." "May 1971." "13030ELY5/71-3. REC-R2-71-3. DWR no. 174-6." Includes bibliographical references (pages 85-90). |
| Contents Notes |
Tile drainage systems of the San Joaquin Valley were monitored for nutrients (nitrogen and phosphorus) to determine the algal growth potential (AGP) of the waste, and the degree of treatment required for removal of AGP. The objectives were to determine: (1) the average nutrient concentrations in tile drainage, (2) the magnitudes of annual, areal and seasonal variability of nutrients and discharges, (3) if a possible correlation exists between nutrients and agricultural practices, and (4) if existing soil conditions influence nutrient concentrations and flows. Average discharges and nutrient concentrations were calculated for different years, months and areas of interest (valleywide, major tiled areas, physiographic positions and soils). |
