34. But. in the same soils, with the same ma- 

 nures and the same tillage, by the addition to the 

 thickness of the ploughed layer of only one-thou- 

 sandth part of lime, the product v vola- 

 tile or fixed, are increased in a manner: 

 the soil of the first named (or lowest) quality 

 reaches the product of the second- 

 rises one-half or more — and tha best (ol 

 the manured soils) increases a fourth. Tli . 01 i 

 Bcale of product becomes 130,201 



and deducting the manure, 106,152,! 

 for the two years- of the rotation. Tl 

 tile soil (sol cT exception) cannot receive lime b< ne- 

 ficially because it contains it already; the; 

 all belongto alluvions, where the call areous prin- 

 ciple has almost always been found in greater or 

 less proportion. 



35. The product of fixed principles [ns i 



in the three classes of limed soils, would be 

 559,868,1290 pounds, and in soluble salts. 

 278,430,645 pounds; and deducting the soluble salts 

 of the manure, the quantities would be 230,334,525. 

 A light addition of lime has then doubled the 

 force of absorption, and almost triplet! the quan- 

 tity of saline principles produced. One of the 

 most remarkable effects of lime consists tl 

 making a soil produce a much greater proportion 

 of saline principles: and if th 

 Lecoq upon the efficacy of saline substances on 

 vegetation arc to be admitted, it would be 

 to the phenomenon of their production thai lime 

 would owe its fertilizing ei 



36. It results from what precedes, that salts are 

 formed in the soil, or in vegetables: thus 

 everyday the nitrates of potash and of lime form 

 under our eyes in the soil, or elsi without 

 any thing indicating to us the ori 



which is contained. But. potash i 

 spontaneously in drawn ashes, according to the 

 observations of the chemisl Gelhen. We i 

 salts also renewed in the artificial nitre beds, with 



the aid of moisture and exposure to the air. But 

 it is the presence of lime that determines this for- 

 mation more particularly. The nitrates abound 

 i Liins of demolished edifices; they are formed 

 in the walls and in all parts of house s situated in 

 lamp places: they effloresce on the buildings of 

 in Cham] ' ■ ponta- 



hed lands of the kingdom ol 

 Murcia. Tl which we see that the cal- 



uces every where, we think 

 it produces in all the soils to which it is given, and 

 where meet the circumstances which favor the 

 formation of nitrates, viz: humidity, veg 

 mould, and i totheair. But, accordingto 



the experiments of M. Lecoq, and othi 

 opinion which is established of the old agricultu- 

 rists, the ni i the most fertilizing sails. 

 It would be then to their formation, which it pro- 

 motes in the soil, that lime owes, in part, its efi'eet 

 on vegetation. 



37. Th. % 1 of the daily formation 



in the soil, and '.. ble life, of saline and 



earthy compounds, taken in nature and on a great 

 scale, are doubt! : snt: but. they may still 



be supported by the experiments and opinions of 

 able men who ha d the same system. 



And first — in the experiment, of Van Helmont, 



in five years, a willow of five pounds grew to 



weigh 169, and had caused a loss of only two 



I which bore it. But the 164 



pounds which the willow had tak ned five 



of ashes, which are due entire!) to al 



ves and the other drop] inj I 

 ..-••. which .. 

 en at least one pound of ashes, which makes up 

 all thai ivhi ' the sheet of 



1 in which 

 iw grew, it in reci ived in the 



nitons circumstances. 

 Boyle has repeated and confirmed thisexpi i 

 in all its parts.

The proportion of soluble salts, 2 per cent, found by Kirwan in barn yard manure, however correctly ascer- 

 tained in a particular case, can no more be relied on as a fixed and uniform proportion, or even a true general 

 average, as used by M. Puvis in the estimates above. En. Farm. Reg.
