IN a paper presented last year to the Grassland. Association Conference attention was directed to an apparent effect of sulphate of potash in overcoming the depression in. yield that follows the repeated use of sulphate of ammonia and superphosphate on the pastures at the Marsden Research Farm, Stoke, Nelson. It is the purpose of this article to show how this effect has operated during the past four years.
