F ROTATION OF CROPS. 



able a climate as that of Scotland, would never answer, as 

 it is very difficult, even in favourable seasons, to sow any 

 quantity of wheat after beans. Oats, instead of the second 

 crop of wheat, would be a great improvement on this ro- 

 tation. 



Five Years' Rotation. Rotations of jive crops, have in 

 many cases been recommended, both for strong and light 

 lands. The excellent rotation on the farm of Stodridge, 

 1. Turnips; 2. Barley, or Spring Wheat; 3. Hay, or cut 

 Grass for soiling ; 4. Pasture ; and, 5. Oats, has been al- 

 ready explained, (p. 129), as the best system for cultivating 

 a turnip soil, with the smallest number of horses. 



Mr Rennie of Oxwell Mains thinks, that a rotation of 

 five, 1. Turnips, or plain fallow; 2. Wheat; 3. Grass; 

 4-. Peas or Beans drilled ; and, 5. Wheat, would, if well 

 executed, answer well on light soils, having a powerful 

 tendency to exterminate weeds. He does not think, that 

 there can be any loss in having a plain fallow, even on the 

 driest soils, it being almost next to an impossibility to clean 

 land so well with green crops, but that there will remain a 

 great many root- weeds, so very prejudicial to the soil. The 

 proper time for doing this effectually, is in July or August, 

 and must be accomplished by deep ploughing, which can 

 never be performed if the land is under a crop. The rota- 

 tion of five, above detailed, is what he means to adopt, if 

 his land tires of wheat every other year; but while the 

 wheat turns out in the manner it has hitherto done, for 

 these some years past, he will certainly continue his pre- 

 sent system of, 1. Turnips; 2. Drilled wheat; 3. Clover; 

 and, 4. Drilled wheat, the most advantageous rotation that 

 can well be adopted in such soils. Beans also, except on 

 Mr Andrew Knight's new system, (that of sowing beans 

 on turnip drills, after the turnips are consumed), do not
