Notes:
An experiment was conducted to examine the response of herbage grazed by dairy cows to sodium fertilizer applied with or without sulphur fertilizer. The residual effects of applying sodium fertilizer in the previous year were also evaluated. The application of sodium or sulphur fertilizer did not affect herbage growth or height, but the application of sulphur fertilizer increased crude protein content of herbage. The increase in sodium content with application of sodium fertilizer was small, but was greater when sodium fertilizer had also been applied in the previous year. Herbage potassium was increased when sodium fertilizer was applied in the year of the experiment, but only if sodium had not been applied in the previous year. Application of sulphur fertilizer increased herbage sulphur content and reduced the contents of boron, chromium, molybdenum and nickel. Cows grazing pasture that had received sodium fertilizer had increased milk yields and the content of lactose in milk, whereas those grazing pasture that had received sulphur fertilizer application had reduced milk yields and the content of milk fat.
