EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



CULTTJEAL EXPERIMENTS. 



In the spring of 1911 our work on coil and crop management was greatly extended. 

 In addition to the inception of rotation tests a comprehensive set of experiments 

 was inaugurated with a view to determining methods of cultivation likely to prove 

 best, within a specified rotation. This work involves 478 plots, each one-fortieth of an 

 acre in extent. Considerable preparatory work was necessary, and even now certain 

 of them have not reached the point where results of value are being obtained. The 

 following brief outline will indicate the object* and nature of this work : — 



Experiment 2A — Depth of ploughing wheat stubble to be sown to oats. 



2B- — Depth of ploughing summer-fallow to be sown to wheat, fol- 

 lowed by oats. 

 20- — Depth of ploughing sod to be sown to wheat, followed by oats. 



3 — Summer-fallow treatment previous to sowing wheat. 

 4A — Treatment of wheat stubble to be sown to wheat. 

 IB — Treatment of wheat stubble to be sown to oats. 

 " 5 — Seeding to grass and clover. 



G — Breaking sod from cultivated grasses and clovers. 

 " 7A — Applying barnyard manure for corn or roots. 



" TB — Applying barnyard manure for wheat. 



" 7C — Applying barnyard manure for barley. 



" 7D — Applying barnyard manure for oats. 



" 8 — Green manuring. 



" 9 — Seed-bed preparation. 



10A— Soil packing for wheat sown on summer-fallow. 

 10B — Soil packing for wheat sown on spring-ploughed wheat stubble. 

 IOC — Soil packing for wheat sown on fall ploughed stubble land. 

 " 11 — Depth of seeding. 



" 12 — Commercial fertilizers. 



" 13 — Under-draining.
