Ottawa : Dept. of Agriculture : Division of Chemistry, Dominion Experimental Farms, 1931. 68 p. : ill. Bulletin, New series no. 145 Title from cover. Historical publication digitized by Internet Archive in 2013 [for Agriculture and Agri-Food Canada]. Issued also in French under title: Fumiers et engrais chimiques : nature, fonctions et application. "This bulletin replaces 'Fertilizers for Field Crops' and 'Soil Fertility', two bulletins dealing with the nature and use of fertilizers and manures and which for some time past have been out of print. Much of the material in these publications has been incorporated in this bulletin but the whole has been rewritten and a considerable amount of new matter, based on the results of recent experiments with manures and fertilizers conducted by the Division of Chemistry, included. In the preparation of this bulletin the close relationship of the use of manures and fertilizers to the maintenance and increase of soil fertility, i.e. productiveness, has been kept in mind. Further, it has been the aim to present the information in terms readily understood by the practical farmer. This bulletin treats concisely of the following important phases of the subject: Farm Manures, their nature, care and application; Green Manures, their value and function; Commercial Fertilizers, their plant food content and economic use, and Soil Amendments"--Introd., p. 5. gccst Fertilizers gccst Manure Wright, L.
