Tankage

Categories: COMMERCIAL SOURCES OF PLANT-FOOD

The waste from the slaughter of animals goes into a product

called tankage. The refuse is cooked for removal of the fat, and then

ground. It may run high in nitrogen on account of the amount of meat in

the mixture, and it may be low in nitrogen and very high in phosphoric

acid by reason of the large amount of bone in the mixture. Only a

guarantee of analysis affords safety to the buyer. It is a relatively

slow and good fertilizer, and is used usually in connection with forms

of plant-food that are more quickly available.
