A. Deep ploughings agree with all soils that are 

 not too light. 



Q. What are the effects of deep ploughing in strong 

 earth or mould ? 



A. Deep ploughing in strong earths or mould, 

 loosens and pulverizes a deeper layer of earth. 



Q. What are the principal results of this deep 

 loosening ? 



A. The principal results of this deep loosening are : 

 lo to allow the roots of the plants to shoot more 

 easily through the soil to draw their nourishment 

 from it, 2o to allow the rain to penetrate more 

 deeply in the earth, which prevents it from accu- 

 mulating around the roots in wet years. 



Q. How can the water damage the roots, whea 

 collected in too great quantities arouiKl them ? 



A. When there is too much wait r around the 

 roots, it causes them to rot, and consequently des- 

 troys the plants. 



Q. In wdiat cases is light ploughing best suitable ? 



A. Light ploughing suits best, !<> in overlight soils, 

 because in this case, one must not seek to loosen the 

 earth which is alreadv too loose ; 2o in cases when 

 the layer of good arable earth is thin, and when 

 loam and gravel are found underneath, etc. 



Q. In what instances is fall ploughing most suit- 

 able?
