At the same time we have the authority ofWarington added to King for stating that fallowing greatly increases thenitrate supply available for the next seasons crop, and the analyses of theSparrovale soils (Table VI.) indicate that the third oat crop grown on theland started its life with too small a supply of nitrates. A Manorial Test. On 2nd November two small plots of j,\, acre were staked off in the oat?crop adjacent to the plots laid down for sampling the soils. One cwt. of. WEIGHING SAMPLES FOR MOISTURE CONTENTS. nitrate of soda per acre was broadcasted on one plot, while the otherreceived no manure. The object was to determine whether the addition ofnitrate to a soil, which had proved .so poor in nitrate at the previoussampling, would benefit the crop. The oats were then 6 inches high. The<:rops were harvested and weighed on 27th December, when the yield fromthe nitrated plot was increasd by 228 lbs. dry hay per acre, or 2 cwt.(nearlv). There had been a fair rainfall after the application of themanure, but the crop was probably too far advanced to make a good it. In concluding this report, we desire to thank Mr. Baird, manager atiiparrovale, for granting facilities for these experiments, and for furnishingajs with the rainfall records.
