I4 MODERN STRAWBERRY GROWING 
2. Thereby very little loss of soil moisture. 
3. Permits a cover crop to winter on the 
soil; stops erosion. 
The general advice for the different soils 
is: Plough a damp or clay soil in the fall 
and if planting is to be done on sod; other- 
wise spring ploughing is advisable, especially 
where a cover crop is desired or where the 
soil is sandy. 
The question now arises, How shall the 
ploughing be done? It is best to turn a fur- 
row at least fourteen inches wide, and not 
completely inverting the soil but having it 
lap over a little on the preceding furrow 
slice. It is also important that the soil 
shall be plowed to a depth of seven inches 
or more, or, in fact, to the subsoil. If the 
topsoil is thinner than seven inches, then 
it would be advisable to plough only a little 
deeper than the topsoil. 
The plough that is used must break up these 
slices as much as possible and leave them 
in as good a condition for harrowing as 
possible. Other than the above, the plough- 
ing must leave the best straight furrows, even, 
well broken, and all ready for the harrow. 
What kind of a plough will give these results?
