regulated according to requirement but depths up to 

 35 centimetres have been attained in Egypt. The amount 

 of ploughing done per day depends upon the nature of 

 the soil and the depth ploughed, but on average good soil, 

 ploughed 25 to 30 centimetres deep, about ten feddans 

 can be accomplished per day of nine working hours. 

 Instead of the plough which inverts the soil a cultivator, 

 which simply stirs it, is sometimes worked by this system 

 and then from twelve to twenty feddans may be cultivated 

 per day. Ploughs are made to turn from three to seven 

 furrows but on average soil and working at ordinary depths 

 four-furrow ploughs are found most satisfactory. The 

 cultivators worked by steam power also vary in size and 

 shape. As steam implements can be worked day and night, 

 land can be quickly prepared for crops. 



Ridging Ploughs. The ridging plough commonly used 

 in Egypt is the ordinary native plough with the addition 

 of a triangular piece of wood to the body of the plough.
