A statistical analysis was made of the results obtained from the Rothamsted Park Grass Plots. There was a significant effect of total rainfall in the period 5th March to 8th July on the yield of hay, but the distribution of the rainfall was of little importance. Rainfall exerted a greater effect when the acidity of the soil was high. Total rainfall during November to February had no significant Cited by: The Park Grass Experiment at Rothamsted in southeast England was started in , making it the longest-running experiment in plant ecology anywhere in the world.

Williams, E. D. ().

A similar effect was recorded in the Park Grass Plots where H. lanatus was found to dominate the sward where the soil conditions consisted of high P availability and low pH (Williams, ). The elemental S treatment gave rise to a lowering of soil pH, presumably by oxidation of the S mediated by the soil bacterium, by:

Abstract. On Rothamsted farm there is an experiment, begun inon the effect of fertilisers on yield and quality of hay from permanent grassland 1, 2, treatments were changed and a few plots were added in the early years of the experiment, in the light of experience gained, but no major changes were made between andand 15 plots still receive their original by:   Bryophyte biomass and species richness on the Park Grass Experiment, Rothamsted, UK.

Abstract. The relationships between bryophyte biomass and species richness and soil pH, nutrient applications and vascular plant biomass and species richness were analyzed for the Park Grass Experiment (Rothamsted, UK).Cited by: The comparative growth in the solutions was closely parallel to the growth of the crop on the plots in the field and corresponded to the composition of the solutions.

The composition of the solutions as regards phosphoric acid and potash corresponded to the past manurial treatment of the soils and to the amount of phosphoric acid and potash they now show on by: 5. The Park Grass Experiment is a biological study originally set up to test the effect of fertilizers and manures on hay yields.

The scientific experiment is located at the Rothamsted Experimental Station in the English county of Hertfordshire, and is notable as one of the longest-running experiments of modern science, as it was initiated in and has been continually monitored ever since.
