    suitable form—e.g., in the following com¬ binations : 1. Calcium nitrate, potassium nitrate, potassium phosphate, magnesium phosphate, ferric phosphate (sodium chloride). 2. Calcium nitrate, ammo¬ nium nitrate, potassium sulphate, magne¬ sium phosphate, iron chloride (or sul¬ phate) (sodium silicate). It is well known that in nature nitrates are formed wherever decomposition of or¬ ganic nitrogenous substances takes place in the air, the ammonia formed by the decomposition being oxidized to nitric acid. These conditions for the formation of nitrates are present in nearly every cornfield, and they are also the cause of the presence of nitrates in water that has its source near stables, etc. In Peruvian guano nitrogen is present partly in form of potassium nitrate, partly as ammonium phosphate and sulphate. In form of ni¬ trate it acts more rapidly than in form of ammonia, but in the latter case the effect is more lasting. Phosphoric acid occurs in guano combined with-ammonia, potash and chiefly with lime, the last being slower and more lasting in action than the others. 2. —Potassium nitrate, 30 parts ; potas¬ sium phosphate, 25 parts; ammonium sulphate, 10 parts ; ammonium nitrate, 35 parts. Where flowers are blooming or where blooming is to be promoted, the application of ammonium nitrate alone is recommended. 3. —Ammonium chloride, 2 parts; so¬ dium phosphate, 4 parts; sodium nitrate, 3 parts ; water, 80 parts. Mix and dis¬ solve. To use, add 25 drops to the quart of water, and use as in ordinary watering. 4. —Ammonium nitrate, 40 parts; am¬ monium phosphate, 20 parts; potassium nitrate, 25 parts; ammonium chloride, 5 parts; calcium sulphate, 6 parts; iron sulphate, 4 parts. 5. —Ammonium sulphate, 30 grams; sodium chloride, 30 grams ; potassium ni¬ trate, 15 grams; magnesium sulphate, 15 grams; magnesium phosphate, 4 grams; sodium phosphate, 6 grams. One gram to be dissolved in 1 liter of water and the flowers watered up to three times daily. Dissolve 4 grams in 1 liter of water and water with this solution daily. 6. —Potassium chloride, 12.5 grams; calcium nitrate, 58 grams; magnesium sulphate, 12 grams; potassium sulphate, 15 grams; iron phosphate, recently pre¬ cipitated, 2.5 grams. This turbid mix¬ ture (1.16 or 1 gram in 1 liter) is used alternately with water for watering a pot of about 1 liter capacity ; for smaller or larger pots in proportion. After using the amount indicated, the watering is continued with water alone. 7. —Sodium chloride, 10 parts; potas¬ sium nitrate, 5 parts; magnesium sul¬ phate, 5 parts ; magnesia, 1 part; sodium phosphate, 2 parts. Mixed and bottled. Dissolve a teaspoonful daily in a liter of water, and water the plants with the so¬ lution. 8. —Sodium phosphate, 4 oz.; sodium nitrate, 4 oz.; ammonium sulphate, 2 oz.; sugar, 1 oz. Use two teaspoonfuls to a gallon of water. 9. —Saltpeter, 5 parts; cooking salt, 10 parts; bitter salt, 5 parts; magnesia, 1 part; sodium phosphate, 2 parts. Mix and fill in bottles. Dissolve a teaspoonful in 1 liter (about a quart) of hot water and water the flower pots with it each day. 10. —Ammonium nitrate, 40 parts ; am¬ monium phosphate, 50 parts; potassium nitrate, 90 parts. Two grams of this fer¬ tilizer suffice for a medium-sized flower pot. 11. —Ammonium sulphate, 10 parts; sodium chloride, 10 parts; potassium ni¬ trate, 5 parts; magnesium sulphate, 5 parts; magnesium carbonate, 1 part; so¬ dium phosphate, 20 parts; 1 teaspoonful to 1 liter of water. 12. —Ammonium nitrate, 40 parts ; am¬ monium phosphate, 20 parts; potassium nitrate, 25 parts; ammonium chloride, 5 parts; calcium sulphate, 6 parts ; ferrous sulphate, 4 parts. Make doses of 2 grams each, which are dissolved each in 1 liter of water and use the solution for water¬ ing the potted plants. 13. —Potash niter, 20 parts ; potassium phosphate, 25 parts ; ammonium nitrate, 35 parts ; ammonium sulphate, 10 parts. Through this mixture a luxurious foliage is secured. If it is desired to act more on the flowering the ammonium nitrate must be omitted. 14. —Ammonium sulphate, 30 parts; sodium chloride, 30 parts; potash niter, 15 parts; magnesium sulphate, 15 parts ; magnesium phosphate, 4 parts; sodium phosphate, 6 parts. Dissolve 1 gram in 1 liter of water and apply three times per day. 15. —Calcium nitrate, 71 parts; potas¬ sium chlorate, 15 parts; magnesium sul¬ phate, 12.5 parts; potassium phosphate, 13.3 parts; freshly precipitated ferric phosphate, 3.2 parts. A solution of 1 gram of this mixture is applied, alternat¬ ing with water, to the plants. After using a certain quantity, pour on only water. 16. —Ammonium phosphate, 300 parts; [37]
