Analysis Of Manure

Categories: CARE OF STABLE MANURE

As has been stated, the content of the manure must

depend chiefly upon the character of the feed. We are accustomed to

combine feeding stuffs in differing proportions for horses, cows, pigs,

and sheep. Van Slyke names the following approximate percentages of

plant-food constituents in fresh excrements of farm animals, the solid

and liquid being mixed:



+----------+----------+------------+----------+

Animal Per Cent Per Cent Per Cent

Nitrogen Phosphoric Potash

Acid

+----------+----------+------------+----------+

Horse 0.70 0.25 0.55

Cow 0.60 0.15 0.45

Pig 0.50 0.35 0.40

Sheep 0.95 0.35 1.00

Hen 1.00 0.80 0.40

He estimates that one ton of average mixed stable manure, inclusive of

absorbents, contains approximately 10 pounds of nitrogen, 5 pounds of

phosphoric acid, and 10 pounds of potash.
