This study was concerned with the most important results of some fertilizer trials on grassland. It was established how the amount of hay gained from the trial fields was extremely divergent. The factors causing these differences and the influence of N, P and K on the chemical and botanical composition of the hay were examined. This was considered separately for each fertilizer. On the chemical composition, attention was especially to N, P, K, Ca and total ash. Part of the trial was on the influence of stage of cutting.
This trial has been of great importance in the further development of grassland research in the Netherlands.
