ON RESULTS OF EXPEEIMENTS WITH 



but have always found tliat sowing broadcast over the drills, 

 after the farm-yard manure had been spread, gave the best 

 results, then drill up and sow as soon after as possible. Eegard- 

 ing the potash mixture, so far as turnips are concerned, I could 

 never detect much difference in bulk of crop, but the turnips 

 seemed to be quite as healthy and kept green in the shaws 

 longer in autumn, more free from dry rot or any other kind of 

 canker, and the clover in the succeeding grass crops was healthier 

 and stronger, I shall mention more fully my experience of 

 potash salts when reporting on the potato crop. 



I have two fields under root crop this season, and as each of 

 them is an average of its own class of soils on the farm, I had 

 them carefully sampled and analysed this spring, with results as 

 under noted. No. I. is a soft brownish-black loam ; No. II. is a 

 thin muirish soil on a clay, and some parts pan gravel subsoil : — 



These two fields have been limed since they were drained, at 

 the rate of about 3 tons an acre, and generally treated for the 

 past ten years as I have previously described in the different 

 modes of manuring my various crops. The one is about the 

 most productive, while the other is about the most unproductive 

 field on the farm. 



I now come to the other, and to me less important division of 

 my root crops, namely, potatoes. I always apply farm-yard 

 manure straight from the yards to this crop, at the rate of from 

 ten to fourteen tons an acre, and all the experiments I have
