Field Experimerds on Clover-Seeds 
the preceding experiments that even on a naturally poor sandy 
soil potash manures do not produce much effect, when the soil, by 
a good system of farming, has been brought into a fair state of 
productiveness, but that the application of purely phosphatic 
manures to such land is more likely to be beneficial, 
Mr. Kimber, in the course of the experiments, took the following- 
field-notes of the appearance of the clovers, which are not without 
interest : — 
Notes made in the Field, April IZtli. 
Plot 3 (Sulphate of ammonia), slightly affected ; rather pale. 
5 (Common salt), very much and injuriously affected ; very 
yellow. 
„ 7 (Muriate of potash), very yellow ; though not so much 
as Plot 5. 
„ 8 (Sulphate of potash), slightly pale and yellow. 
„ 11 (Muriate of potash and superphosphate), much affected 
by the manure ; very yellow. 
Notes made May 22nd. 
Plot 1 (No manure), useful fair crop. 
2 (Nitrate of soda), about the same as Plot 1. Blades of 
grass and weeds darker in colour, but little difference 
in the clover-plants on Plots 1 and 2. 
,, 3 (Sulphate of ammonia), slightly better than Plot 2. 
„ 4 (Mineral superphosphate), much higher and better than 
Plots 1, 2, and 3. 
„ 5 (Common salt), worse than any of the preceding plots. 
„ 6 (No manure), slightly better than Plot 5. 
„ 7 (Muriate of potash), rather better than Plot 6. 
8 (Sulphate of potash), better than Plot 7, and darker in. 
colour. 
5, 9 (Sulphate of lime), about the same as Plot 8. 
„ 10 (Mineral superphosphate and nitrate of soda), darker in 
colour and better than Plots 8 and 9. 
11 (Mineral superphosphate and muriate of potash), about 
as good as Plot 10, but paler ; affected rather injuri- 
ously by the manures in spots. 
„ 12 (No manure), not so high and good as Plot 11. 
The clover-plants, it appears, were too powerfully affected at first 
by the more soluble saline manures. However, several of the 
plots which In the beginning looked very yellow had gradually 
improved, and towards the conclusion of the experiments quite 
recovered from the too energetic effects of the saline manures. 
The after crop of clover was not weighed, but the following^ 
notes were taken in the field : — 
Plots 1 and 2. Accidentally mutilated by sheep.
