Manurial Treatment Recommended on Different Soils. 



LOAM SOILS On loam soils of average quality the following 

 formula is recommended : — 



N.B. — The Lime should be applied about one month before the 

 other manures. The other manures may be mixed together and mixed 

 with earth and spread. In subsequent years half the Ammonium 

 Sulphate can be rr^placed by orj^anic nitrogenous manures, oil cake, 

 blood meal, etc. and the Superphosphate by Bone meal or Phosphatic 

 Guano. 



CLAY SOILS: — One half of the Ammonium Sulphate might 

 suitably be replaced by oil cake — using quantities containing an 

 amount of Nitrogen equivalent to that in the Ammonium Sulphate 

 replaced. The Superphosphate should be replaced by Basic slag or 

 Guano — preferably the former. Potash salts may frequently be 

 omitted. Lime should be applied at the rate of 1500 — 2000 lbs. per 

 acre. 



SANDY SOILS.— At least half of the Ammonium Sulphate 

 should be replaced by organic nitrogenous manures i.e., oil cake, etc., 

 using a quantity of cake containing Nitrogen equivalent to the 150 

 lbs. of Ammonium Sulphate — as sandy soils are often very deficient 

 in Nitrogen. 



Potash salts (Chloride or Sulphate of Potash) should be applied 

 at the rate of 200 — 250 lbs. per acre. Basic slag is preferable to 

 Superphosphate, as a source of Phosphates. Lime should be applied 

 at the rate of lOOO lbs, per acre. 



PEATY SOILS: — Nitrogenous manures may be generally 

 omitted ; if used, a small quantity of Sodium or Potash Nitrate — say 

 100 lbs. per acre might be applied, as Ammonium Sulphate tends to 

 produce acidity. 



Phosphate should be applied preferably as Basic slag or Guano. 

 Potash salts maybe applied as in the case of loam soils. Lime is 

 especially important and should be applied at the rate of 2000— 3000 

 lbs. per acre. 



The following table will indicate the quantities to be supplied 

 of any particular manure when substituted for either Ammonium 

 Sulphate, Superphosphate or Potassium Sulphate. The above auanti- 

 ties should be increased by at least one half on poor soils
