PHOSPHATIC GUANO, 



FROM THE ISLAND OF SOMBRERO, West Indies, 



THE RICHEST DEPOSITE OF PHOSPHATE OF I>1ME KNOWN TO THE WORI.D. 



By a careiVil analysis of an average sam})le of different cargoes, the annexed eminent Chemists 

 have found this remarkable deposite to contain of Phospliate of Lime, as follows:

Thus proving it to average the richest deposite of Phosphate of Lime known to the world. 



Pure Bone Dust contains but 55 or 56 per cent, of this important Phosphate; hence a compari- 

 son of the relative value of the two, will at once show which is the most desirable for Agricultural 

 purposes. 



Guanos are of two distinct species— those in which the Phosphates of Lime predominate, as 

 in Sombrero, and others ; and those in which Annnonia predominates, as in the Peruvian. Both 

 experience and theory establish the fact, that Ammonia aiul Phosphate of Lime are essential in- 

 gredients for a general fertilizer, and, consequently, for general pur])oses, a proper mixture of the 

 two is recommended: whilst the Peruvian and other Ammoniated Guanos, are mere stimulants or 

 qnickentrs of the soil, the Sombrero and other Phosphatic Guanos, are permanent fertilizers, but of 

 sloM^er action and less perceptible effect the first year, unless aided by some stimulants. Hence 

 the great importance of combining the two in proper proportions, which, if done, makes the best., 

 most convenient^ and economical fertilizer known, Assvuuing the cost of Peruvian Guano at ^62, 

 and Sombrero at ^$34 per ton — and with one-quarter of the former, mix three-quarters of the 

 [ntter^ (lahich proporiio)is are recom7nencIed by experienced Fanners^) it gives, 'at a cost of about $41 

 per ton, a fertilizer far more valuable and permanent than the Peruvian alone. The agriculturist 

 need only be reminded of the nature of the two predominating ingredients, in the different species 

 of Guano, to enable him to understand the proper mode of its application. Whilst Ammonia (in the 

 Peruvian) is liable to evaporate or rise, Phosphate of Lime (in the Sombrero) is heavy, and liable to 

 sink below the reach of the roots of plants Therefore it should be either deposited in the hill, or 

 drill v/ith the crop, or used as a top dressing, in the proportion of from 200 to 400 lbs. to the acre, 

 according to the wants of the soil. If used as a top dressing, the Spring is the best time, when 

 the crop is assuming its strength and sustenance, as, at that time, the benefit of the Ammonia is 

 less likely to be lost than if used in the Fall or earlv Winter.
