Irrigation of Liicernt 



of the Goulburn Valley. Other questions to be studied, were the fre- 

 quency with which water needs to be applied under irrigation, and the 

 treatment of the soil required to promote the growth of the crop. 



The diagrams on pages 182 and 183 show the manner of grading and 

 applying water adopted at Tatura. 



The first field prepared was of an undulating character, giving an 

 opportunity of testing a number of methods of applying water. The 

 second field had a uniform slope, and here the method of applying water 

 best suited to such slopes was adopted. The diagram shows the manner 

 in which the water is applied.

 LAND GRADER. 



Using a stream of about 6 cubic feet per second, the field can be 

 Avatered in one working day, if the water is' turned on at about daylight 

 and continues running until as long as one can see to handle it. The 

 average depth of water used in one irrigation is about 3 inches, and thus 

 far it has required from one to two waterings for each crop or from 

 six to ten waterings a year. 



The two tools used in the grading of these fields were the buckscraper, 

 and a grader manufactured by a local blacksmith. Illustrations of both are 

 given.
