STORING FERTILISERS.

It sometimes happens tlint a fanner finds that, he has a quant it y of iertilisor left over, nm ' liavo to keep it. in store for Hie following season. How much of its value will it lose (luring the six months' storage? The following information upon the subject is furnished by tile Farmers' Express. It says that nitrate of soda can ho kept for a considerable time without, loss of value if stored in a good shed with a dry floor. When wanted for uso in due course the nitrate will probably bo found to have set, and in that case will have to be emptied out of tho bag and broken up, which can easily be done with a shovel. Sulphate-of ammonia can also be held in store over tho dead season if stored in a shed free from damp. If it cakes it must he broken up before use. The ncu tral quality now in use is less liable to becomn hard than tho old kind. Superphosphate <jan be kept without loss in a dry shed; it is liable to cake to a certain extent, and a pcrtion of tho phosphate, soluble in water, may retrograde, but practically the fertiliser retains its fertilising value and can bo used with confidence. If it has become damp tho remedy is to spread it out on a dry floor and mix a little dry earth with it. Basic slag and raw ground phosphate can be kept in store without risk of loss in value. If they become caked it is simply necessary to shoot tho stuff out of the ba£ and break it up.
