    Notes: Summary Gypsum at rates of 0, 25, 50 and 100 and 200 lb per acre was applied to a grass-legume association, and the effects on the yields of dry matter, nitrogen and sulphur were followed for four seasons. Pronounced residual effects were noted and had not completely disappeared by the last harvest. Underground transference of nitrogen from clover to grass over the four years was about equal to the nitrogen harvested in the clover. Of the sulphur applied, 80, 80, 50 and 30 per cent were recovered from the 25, 50, 100 and 200 lb rates of gypsum respectively. Eight to twelve pounds of nitrogen were fixed for each pound of sulphur recovered.

    Competition for sulphur in a grass-clover association (1958)

    Notes: Summary A 3 × 3 factorial experiment with nitrogen and sulphur fertilizers was carried out on a grass-clover association in an area where there is little if any cyclic return of sulphur. In the absence of sulphur, grass took up 98 per cent of the total uptake of sulphur, and nitrogen fixation by associated clover was negligible. In the absence of fertilizer nitrogen, dressings of sulphur as gypsum stimulated clover growth; at a low rate of application of sulphur, nitrogen fertilizer increased grass growth and clover was suppressed. This suppression was largely overcome with a higher dressing of sulphur. Sulphur therefore must be added to the group of elements (phosphorus, nitrogen and potassium) for which grass may compete intensely when grown with clover and when nitrogen fertilizers are applied to a grass-clover association adequate supplies of sulphur must be assured in order to minimise suppression of clover. Sulphate of ammonia may stimulate clover growth under these conditions. Solubility of gypsum was low in a dry season and residual effects were pronounced.

    Notes: Summary 1. Gypsum was applied at various levels to a grass-clover association, and its effect noted on the yields and composition of both components. 2. Both clover and grass responded markedly and a three-fold increase in dry matter and a four-fold increase in yield of N were noted. 3. The extra nitrogen in the grass was shown to have been derived almost certainly by underground transference from the clover, the amount involved approximating to the amount of N retained in the aerial part of the clover. 4. Whilst a high proportion of the S applied was recovered at rates up to 50 lb gypsum per acre, a low recovery was obtained from greater applications, and as residual SO4 was very low, it is presumed that SO4 was readily leached during one or two periods of heavy summer rainfall. The ease with which SO4 is lost by leaching may merit attention to forms, times and rates of application of S. 5. Nearly all the S in the clover was organic, whereas a big fraction of the S in the grass was SO4-S. In regions where atmospheric returns of S are small and where no S is being made available from the weathering of S-containing minerals, S must be applied in some form or other to promote optimum N-fixation by legumes as grass may utilise almost all the mineral N and S made available from soil organic matter. 6. Over large areas of the South Island of New Zealand it is doubtful if more than 1 lb S per acre is returned annually from the atmosphere and the application of S is of some considerable importance to promote N-fixation by clovers and hence high production from grass-clover associations.
