The relationship of N to some other anions was investigated for plants grown in infertile soil low in soil organic matter from bare desert areas compared with plants grown in more fertile soil from around natural shrub clumps. The objective was to determine nutrient relationships in the infertility of desert soils even when supplied with N. Range grass [ Hilaria rigida (Thurb.) Benth. ex Scribn.], barley ( Hordeum vulgare L. ‘Atlas 57’), and bush beans ( Phaseolus vulgaris L. ‘Improved Tendergreen’) were grown in such soils in a glasshouse. The latter two were with and without addition of N fertilizer. Plants grown in the infertile soil compared with the fertile soil had greatly decreased yields, were low in N, generally had increased concentrations of Si, and had slightly less total cation concentrations. Nitrogen fertilizer improved yields only slightly in the infertile soil but it increased N concentration and decreased that of Si in plants. The Si seemed to enter into the cation‐anion balance in the plants.
