Theavailable store of potash in thesoil is much increased by thethorough tillage which hasalready been recommended,but in bearing orchards it should also be suppliedevery year in some commercial form. One of the bestsources of potash for orchards is unleached hard-woodq^shes. It gives fruit a high color. Forty or fiftybushels to the acre is a good dressing. Muriate of potash is perhaps the best and mostreliable form in which to secure potash at the presenttime, says Cornell Bulletin No. 72. Commercialsamples generally contain about fifty per cent, ofactual potash. Kainit or German potash salts is amuriate of potash containing about twelve per cent,of potash. An apple orchard in full bearing and uponloose soil may receive as high as 1000 pounds of muri-ate of potash per acre, but a normal and economical. PEACHKS WELL PROPS NEEDED HERE! 56 ORCHARD BOOK application is from 500 to 700 pounds. Sulphate ofpotash is also thought to be a good form in whichto buy potash. The commercial article will analyzefifty per cent, or less of actual potash. Phosphoric acid may be obtained in the form of ahigh-grade plain superphosphate (dissolved SouthCarolina rock), in bone compounds, and Thomas plain superphosphate contains about sixteen oreighteen per cent, of phosphoric acid, and 300 to 500pounds per acre is a liberal and very useful dressingfor bearing orchards. The bone fertilizers are alwaysvaluable. Those which are untreated give up theirphosphoric acid slowly, unless they are very finelyground. Dissolved bone gives more immediate or basic slag has given good results in manytests, but it parts wath its fertility very slowly. Phos-phoric acid is
