* Jabrbiicher der “ Cattedraambulante”’ von Professor Tito Poggi, Rovigo. 
The highest yield was obtained where all three of the plant-food 
ingredients had been applied, and on these plots a very good after effect was 
produced in the second year. Phosphoric acid proved very beneficial, especially 
upon the yield of grain. ‘ ‘ 
Professor Poggi, Rovigo, makes the following recommendations for the 
quantities of fertilising materials to be applied per acre:— 
Tor New For Exhausted 
Fields. Fields. 
Sulphate of ammonia ... ey 89:0 Ib. 178 Ib. 
Acid phosphate (16 per cent.) 2225 ,, 356 ,,- 
Muriate of potash... — 4405. ,, Bom 
267 to 356 lb. plaster or slaked lime should be applied to soils deficient 
in lime. 1n case of light soils, the quantity of muriate of} potash applied per 
annum should not be less than 89 lb. 
However, too much potash should not be applied to water rice, as this 
ingredient produces a Juxurious formation of straw at the expense of the yield 
of grain, American rice-planters always recommend large quantities of potash 
for upland rice, holding that this is necessary to obtain a heavy yield of grain. — 
Mr. C. K. McQuarrie, of De Funiak. Springs, Florida, holds that the presence 
of empty husks of upland rice is due to a deficiency of potash. He makes the 
following suggestions in regard to the planting of upland rice on the rather 
light soils of Florida :—. 
If a crop is going to be made cn new land, it should be well ploughed 
during the previous winter, and harrowed over and over again, until all the sod 
is broken up. At the last harrowing 400 lb. of kainit per acre should be 
seattercd broadcast. When ready to begin planting, furrows should be run 
with a bull-tongue plough, about 3 feet apart. In these furrows scatter about 
300 Ib. fertiliser per acre, containing phosphoric acid and potash, not less than 
8 per cent. of each. This fertiliser must be well mixed with the soil by dragging 
a chain in the furrow. The seed must be sown liberally, as at least 25 per 
cent. of the rice generally grown is nothing but empty husks. After the plants 
are up, treat the crop to a little to»-dressing of nitrate of soda. If the crop is 
planted in March or beginning ef April, we can always depend on getting a 
second crop from the stubble of the first crop. This second crop is generally 
not so good as the first, but if fertilised when the first crop is cut it will repay 
us for our trouble. 
Rice must not follow itself on the same land, as it greatly impoverishes 
the soil, but if we want to continue it on the same land green manuring and a 
liberal application of potash are absolutely essential. The leguminous plant 
should be sown early in the spring, and can be ploughed under in time for the 
first planting.
