1909-] Summary of Agricultural Experiments. 783 



Experiments are also in progress on five farms in Staffordshire, and 

 the results are given for several years. 



Manuring of Meadow Land (Univ. Coll. of Wales, Aberystwyth. 

 Reports on Expts., 1906). — An experiment which is to be continued for a 

 number of years was commenced on a farm at Waunifor. Fifteen small 

 plots were dressed with various artificial manures, and the results are 

 given, both as regards the total yield, and the value of the crops after 

 deducting the cost of the dressing. The . best returns were obtained from 

 complete dressings, and it is remarked that "as is generally the case 

 with meadow land in Wales, where many crops have been removed in 

 succession without any return being made in the form of either natural 

 or artificial manures, a full and profitable crop cannot be obtained without 

 supplying to the land the three most essential ingredients of plant food." 

 Some observations are made on the character of the herbage resulting 

 from the application of the manures. 



Another experiment, commenced in 1905, was intended to determine 

 the effect of farmyard and artificial manures on the yield of hay. The 

 conclusions arrived at are (1) that in manuring meadow land the best 

 results are obtained by using a complete dressing ; (2) that of the three 

 ingredients of plant food, nitrogen is the one most required, and potash 

 least of all ; (3) that the application of lime is unremunerative, and even 

 tends to reduce the crop of hay produced ; (4) that alternate dressings of 

 farmyard and artificial manures not only yield very heavy crops, but they 

 are also most profitable. The experiments were carried out on a field 

 of light loam, which had been mown for several years without the appli- 

 cation of much manure of any kind. 



A somewhat similar experiment is also in progress on another field 

 at the College Farm, which has been grazed for many years, the object 

 being to test the effect of the various manures on the quantity and 

 quality of the herbage, As the experiment is to be continued over a long 

 period, the report only gives a statement of the results in 1906. 



Manuring of Pasture (Agric. Students' Gazette, Cirencester, Vol. 

 XIII. Part 4; Vol. XIV. Part 1. — These two publications contain 

 reports on the results obtained in 1907 and 1908 from 20 plots, each ^0 

 acre, which have been manured experimentally at Cirencester for some 

 seventeen years or more. 



Manuring of Pasture (Beds. C. C. Agric. Education Com., Report 

 on Demonstration Plots, 1907). — Demonstrations were carried out at two 

 centres, but it is stated that it is difficult to draw any decided conclu- 

 sions from the results obtained. 



Manuring of Old Pasture (Armstrong Coll., Newcastle-on-Tyne, 

 Agric. Dept., College Bull. No. 7). — Experiments in the manuring of 

 old land hay have been carried out at six centres in Cumberland for 

 thirteen years, at three centres in Durham for six years, at one centre 

 in Northumberland for thirteen years, and at Cockle Park for eleven 

 years. The results were summarised in this Journal, July, 1908, p. 284. 



Experiments have also been carried out in Cumberland to test the 

 effect of manures on poor pea«ty and marshy lands, of which large areas 

 exist in that county. A summary of these experiments was given in 

 this Journal, May, 1908, p. 120. 



Manuring of Seeds Hay (Edinburgh and East of Scotland Coll. of 

 Agric, Bull. XIII). — Experiments in the manuring of seeds hay have 

 been conducted by the Edinburgh and East of Scotland College of Agri-
