SUMMARY OF AGRICULTURAL EXPERIMENTS. 

 Experiments with Clover and Grass* 



Manuring of Grass Land (Jour. Roy. Agric. Soc, Vol. 69, 1909). — 

 Broad Mead was the only field hayed in 1908, manures having been 

 applied in 190 1, 1904, and 1906. Botanical separations of the herbage 

 were made. The heaviest crop (2 tons \\ cwt.) was given by 12 tons 

 farmyard manure, but the herbage contained little of the leguminosae. 

 Next came the plot dressed with 10 cwt. basic slag and 1 cwt. sulphate 

 of potash, but the only dressing that markedly increased the leguminous 

 herbage was 5 cwt. mineral superphosphate and 1 cwt. sulphate of 

 potash. Lime, 2 tons per acre, gave no increase over the unmanured 

 plot, but the finer condition of the herbage produced was most notice- 

 able. In 1908 the percentage of leguminous herbage was much lower 

 generally than in 1905 and 1907. 



Manuring of Grass Land (Rothamsted Expt. Stat., Annual Report, 

 1908).- — The weights are given of the crops on the permanent grass 

 plots (53rd year of the experiment), and also the botanical composition 

 of the herbage. 



Manuring of Grass Land (Harper-Adams Agric. Coll., Field Expts., 

 1908). — The effect of continuous manuring of meadow land which is 

 mown each season is being ascertained on a pasture field laid down 

 many years ago. Ten plots have been dressed each year since 1903, and 

 the crops and the net profit, after deducting cost of manures for 1908, 

 are given and compared with former years. The highest net profit 

 G£i 195. per acre) was given by 3 cwt. superphosphate, and the next 

 (£1 is. 4^.) by 10 tons farmyard manure every fourth year, with com- 

 plete artificials in the intervening years. In the summary of the results 

 for the first four years it was shown that superphosphate, alone or in 

 combination, was essential for an increased crop on this land, and this 

 continues to be the case, its effect on the quality of the herbage being 

 very marked. 



Experiments on the manuring of meadq,w hay were also conducted 

 on seven farms in Staffordshire. These trials have now been carried on 

 for from one to ten years, and the results for 1908 and the average for 

 the series of years are given.
