MANURING SWEDES. 
J. Epwarps, Toowoomba— 
Question.— W hat is the effect of manuring swedes ? E 
Answer.—This is rather a singular question to come from a district so 
celebrated for the wonderful fertility of its soil. We have seen 
swedes of immense size grown both below and above the Range, 
without the aid of manure. However, as it may be of use to some 
farmers on poorer lands, we give you the following :—Suppose your 
land to be manured with 4 cwt. superphosphate and 2 ewt. kainit 
per acre, and put the yield of roots at 16 tons per acre. Now add 
+ ewt. nitrate of soda, applied in the drills. The return should be 
over 18 tons, or, say, an increase due to nitrate of soda of 2 tons 
per acre. 
A greater quantity of nitrate will result in a smaller increase. 
For instance, if 1 ewt. of nitrate of soda be applied, the increase 
will be about 14 tons; whereas the application of 13 cwt. only gives 
an increase of 183 ewt. 
Sulphate of ammonia applied in drills has little effect. As a top- 
dressing, in addition to # ewt. applied in the drills, 3 cwt. (apolied 
after the plants are thinned) will give an increase of about 17 cwt. 
In both cases, the results depend greatly on the state of the 
weather. 
MANURE FOR TOMATOES. 
Marker Garpenrr, Coorparoo.—Tomatoes will not stand heavy manuring 
after the fruit has set; it delays the development and ripening of the 
fruit. We have had practical evidence of this in our own garden. In the 
early stages of development, nitrogen, phosphoric acid, and potash may be 
liberally supplied with advantage. A good manure is made up as follows :— 
2 parts nitrate of soda, 2 parts bonemeal, 3 parts kainit, and 4: parts super- 
phosphate (parts representing either ounces or pounds of each ingredient). Of 
this mixture, 1 oz. per square yard of soil may be applied weekly from the time 
the plants are established till the fruit has set. Superphosphate has been found 
to hasten the maturing of the fruit. 
PASPALUM DILATATUM. 
C.B., Taabinga, Nanango— 
Question —Can Paspalum dilatatum grown in a cultivated paddock be 
again eradicated, or does it partake of the nature of Johnston and 
and other noxious grasses ? 
Answer.—Mr. F. M. Bailey, Government: Botanist, says that Paspalum 
dilatatum is a grass for which farmers cannot be too thankful. It 
is as easily eradicated as any ordinary grass, and does not in the 
least partake of the nature of Johnston or other noxious grasses. It 
makes a splendid turf, and when ploughed under forms an ideal bed 
for growing melons. 
COMMERCIAL BUTTER. 
H. H. Szazsory, Beaudesert— 
Question.—Which cow would give the greatest amount of commercial 
butter fat from the following figures P 
No.1. 19°75 1b. milk. Test, 3:5. 
No.2 18 4 38. 
Answer.—No. 1 would give the greater amount by as nearly as 
possible lb.
