Field Experiments on Clover- Seech.

It was well drained and in good state of cultivation. On analysis 

 it furnished the following results : —

 The soil, it will be seen, is poor in phosphoric acid, and 

 contains only a moderate proportion of potash and soda. It is 

 naturally rather a poor soil, and not particularly well adapted for 

 the growth of clover. 



The various top-dressings were sown on April 5, 1865, and 

 the plots Avere mown June 20. Unfortunately, owing to a 

 mistake, the produce was left on the ground three days before 

 weighing, during which time probably more than half the 

 amount of moisture in the green clover-seeds evaporated. How- 

 ever, as the plots were all mown at the same time, and the grass 

 left for the same length before the weighing, the results contained 

 in the subjoined Table are nevertheless reliable and comparable 

 with each other : —
