MIXING MAURES.

A word of caution (says the South Australian Journal of Agriculture) may he given with reference to the mixing of artificial fertilsers. Sulphate of ammonia must not he mixed with any manure holding free lime, such as Thomas' phosphate (basic slugs), liy mixing these, a chemical action lakes place, s.'ltin" free ammonia, the presenea of which in the air can he detected hy its pungent odour. It is (juito saf*, however to mix sulphate of ammonia will) sum rphosphate, dissolved boims, honemeal, kainit, sulphate of pnlasii, miniate of potash, p.nd nitrate of sola. *()i\ tlm other ham), uiuaie ot soda should not be mixed wi'h superphosphate, dis solved hones, or guano treated with sulphuric acid, as such a mixture gives rise to the loss of nitrogen, and the mass becomes sticky and difficult to sow. In applying superphosphate and dissolved hones it is undesirable to mix either with Thomas' phosphate, as this may cause the reversion of the soluble phosphate present. -If potassic manures are mixed for any considerable time with a dissolved manure the mixture becomes sticky and difficult to sow; hence, speaking generally, the the sooner the mixture of manures) is sown after it is made the better.
