 plant food sold in Massachusetts was as follows: 



Plant Food Elements (Tons) 



Fertilizer Nitrogen Available Potash 



(Tons) Phosphoric 



Acid 



Mixed fertilizers 45.339 2,355 3,796 3,326 



Unmixed fertilizer chemicals and materials 22,360 1,434 2,015 745

Full details of the fertilizer and lime inspection will be found in Control Bulletins 

 95 and 97 



Miscellaneous Analytical and Diagnostic Work. (H. D. Raskins, H. R DeRose, 

 A. F. Spelman, J. \V. Kuznieski.) Chemical studies in cooperation with several 

 departments of the Experiment Station, Field Station, County Agents and men 

 in charge of the Soil Conservation work of the State have been carried on. The 

 character and extent of this work is shown in the following summary: 



Apples for ash analysis 18 



Apple spray residue 5 



Apple tree leaves, ash analysis 35 



Cranberry spray residue 4 



Fertilizer mixtures 24 



Fertilizer chemicals 2 



Fertilizer for manganese determination. 



A.O.A.C 6 



Fertilizers for basicity and acidity deter- 

 minations, A.O.A.C 4 



Forage and field crops 276 



Grain rations 2 



Limestone, dolomite, A.O.A.C 9 



Liquid lime-sulfur 



Maple syrup 



Peat 



Potato spray 



Salt water sedges and grasses 



Seed residues 



Total 400 



Other work of the department has included consultations on various projects 

 where chemical problems were involved. Research on problems developed by 

 the referees of the Association of Official Agricultural Chemists of North America 

 has received the usual attention and has included work on methods for the de- 

 termination of manganese and acidity-basicity in fertilizer mixtures, the chemical 

 work involved in these studies being performed by Mr. J. VV. Kuzmeski and Mr. 

 A. F. Spelman respectively. A considerable variety of chemical work has, as 

 usual, been done for other State Institutions, community organizations, firms 

 and individuals having problems of agricultural interest. This group includes 

 the analyses of the following materials: 



Animal tissues for mineral poisons 4 



Crab and lobster shell meal 1 



Dehydrated poultry manure 2 



Ground bone 2 



Hide scrapings 1 



Hoof meal 1 



Lime products 7 



Miscellaneous 3 



Mixed fertilizers 13 



Nitrate of Soda 1 



Organic waste product from caneme plant 2 



Orchard hay for spray residue 6 



Peat 5 



Peat poultry manure 



Refuse from duck pens. . . 

 Servall stable bedding. . . . 

 Sheep manure-wool waste.
