Abstract

In a field experiment applications of manure decreased soil acidity but increased total nitrogen, organic matter and adsorbed plus easily acid–soluble phosphorus. Where either peat moss or sawdust was applied there was an increase in soil acidity, total nitrogen and organic matter. The effects of other treatments, e.g., hay and hay compost, were less marked.The phosphorus level in strawberry leaf samples from manured plots reflected the improved phosphorus status of the soil but none of the treatments resulted in significant differences in levels of nitrogen, potassium or calcium in the leaves.All treatments gave highly significant increases in yield. However, the yield with either hay compost or hay was significantly higher than with manure.
