| Wastewater irrigation of agricultural land for treatment and disposal can be an effective management system that should be, where feasible, a consideration for wastewater treatment. Irrigating agricultural land with food processing, municipal, and some industrial effluents has been successful for many years in the USA, the Netherlands, and elsewhere where the systems were conservatively designed and the water and nutrient applications were not excessive (Smith, and others, 1975, 1976, 1977, 1978, 1980, 1983; and DeHaan, et al. 1973,). Some advantages associated with wastewater irrigation systems may relate to lower initial costs of development than the conventional secondary wastewater treatment but the cost advantage does not always remain with... |

| Irrigation with potato processing waste water was studied for 3 years at five locations in southern Idaho. Three of the potato processors surface irrigated and two sprinkled land planted to perennial grasses. The processing season began in October and continued into the following summer. Samples of 24-hour composited waste water and soil water, extracted from depths of 15 to 150 cm, were obtained monthly throughout the year. Analyses were made on all water samples of sufficient volume for chemical oxygen demand (COD), NO3 , total N, total P, ortho P, hydrolyzable P, K, Na, Ca, Mg, Cl, HCO3 , SO4 , electrical conductivity, and pH. Water applications ranged from 160 to 490 cm per year, total N from 1,000 to 2,200 kg, P from 150 to 630 kg, and... |
