| Abstract:
Field trials of landscape plants determined their tolerance of recycled water irrigation. Ten landscape plant species exhibited substantial differences in salt tolerance. Plants were more susceptible to salt stress under sprinkler irrigation than under drip irrigation, because substantial amounts of salt were taken up by the leaves. Salt tolerant plants took up less salt than salt sensitive plant species. No single salt stress symptom was detected for all the 10 landscape plant species. Soil salinity reached about 2 dSm-1 in the fall of 1997 and reduced to less than 1 dSm-1 in the spring. Screening for salt tolerance using field planting and sprinkler irrigation is possible, but additional research is needed. | |
