AbstractThe relationships of soil salinity, ash, and crude protein were determined in seven natural populations of fourwing saltbush (Atriplex canescens). The correlation coefficient between soil salinity and ash was -0.31 and between ash and crude protein, -0.33. Ash content ranged from 11.9% to 18.7%; the overall mean was 14.8%. Soil salinity directly beneath the plants varied from 234 parts per million (ppm) to 4,229 ppm. Crude protein ranged from 8.9% to 22.4%; the overall mean was 14.9%. Some of the populations contained significantly higher levels of crude protein than others. Also discussed is the difference in ash accumulation of Atriplex spp. growing in soil as opposed to those growing in nutrient solutions.
