The Use of Wastewater for Agricultural Irrigation

A review of the fate of potassium in the soil–plant system after land application of wastewaters

“…Thus, it seems that potassium concentration in effluents and sewage from domestic sources are in the order of 10-30 mg L −1 . The concentrations result, in part, from accumulation during domestic water use, additions of potassium of 7-15 mg L −1 are reported for California [10] and 18.8 mg L −1 in Israel [8].…”

“…The potassium utilized by several crops is shown in Table 5. Some plants such as banana (Musa sapientum) and lucerne (Medicago sativa) have an extraordinary capability to accumulate potassium (up to ∼1200 kg ha −1 ) [10]. In planning for the effective use of wastewaters with high potassium levels it is important to know not only the overall nutrient uptake, but also the plant removal efficiency.…”

Irrigation with Treated Sewage Effluent

“…Noy and Feinmesser (1977) have tabulated the typical composition of domestic wastewater, originating from Lake Kinneret supply water (Table 4.7). Winter (November-March) is cool and wet, but the rest of the year is dry, and evapotranspiration greatly exceeds rainfall.…”

“…Valuable information on eIDuent irrigation has been gained in Israel, where shortage of water stimulated research on different aspects of the subject (see Noy and Feinmesser 1977;Shelef 1977;Feigin et al 1978).…”
