TABLES SHOWING RELATIVE MANURIAL VALUE OF NITROGEN AND POTASH IN
DIFFERENT SUBSTANCES.

_Wolff, 1893._

Nitrogen in form of ammonia and nitrates, and easily
decomposable organic compounds, as dried blood,
flesh-meal, meat-meal, Peruvian guano, and as urate 100
" in fine steamed bone-meal, fish-guano, oilcakes, and
better kinds of artificial guano 85
" in fine bone-meal and horn-meal 77
" in coarse bones and horn-shavings, woollen refuse,
farmyard manure, and poudrette 61

_American, 1892._

" in ammonia salts 100
" as nitrates 86
" in dry and fine-ground fish, meat, and blood 91
" in cotton-seed meal, and castor pomace 86
" in fine bone and tankage 86
" in medium bone and tankage 68
" in coarser bone and tankage 43
" in hair and horn-shavings, and coarse fish scrap 40
Potash as high-grade sulphate, and in forms free from muriates
(or chlorides) 100
" as muriate 82

Professor Wagner has drawn up, from numerous experiments, the relative
manurial values
