Abstract: Effects of chloride (Cl) fertilisers (NaCl and KCl) on the ionic composition (K + , Ca 2+ , Mg 2+ , Na + , NH + 4 , H 2 PO ‐ 4 , SO 2‐ 4 , Cl ‐ , NO ‐ 3 ), and cation‐anion (C‐A) balance and ratio of fodder beet ( Beta vulgaris L.) were studied under field conditions on two New Zealand soils (Templeton siltloam, Dystic Ustochrept; and Wakanui silt loam, Aquic Eutrochrept). In both soils, at mid season and final harvest, Cl application at 360 kg/ha (590 kg NaCl and 758 kg KCl) increased root K + and Cl ‐ , and Cl ‐ in tops consistently but not K + in tops. The sum of cations (SC) and C‐A remained unaffected whereas the sum of anions (SA) increased. With increasing rates of NaCl, root cations were not significantly affected whereas topsand root Cl ‐ increased linearly, indicating that Cl ‐ was easily absorbed and accumulated in both tops and roots of the beet crop. The beet crop maintained constant SC and C‐A balance within the range of 0–1180 kg NaCl/ha applied, but the SA increased linearly with increasing rates of NaCl applied. The ratio (RCA) of SC and SA provided a more consistent and reliable index of yield compared with C‐A balance. Beets with low RCA were apparently associated with high fresh and dry root yields and fresh sugar yield.
