114 ECONOMY OF FARMING. 



their place, one needs then | of the field for fodder, in order to plant f with grain: 

 For example, 100 yokes ( = 142.2 acres), of plough land, lie in the following rota- 

 tion : 1, Maize, manured ; 2, Barley ; 3, Clover j 4, Wheat ; 5, Vetches, manured ; 6, 

 Oats ; 7, Vetches ; 8, Oats. 



Acres. Bushels. 



12.5 yokes (17 A) of Maize, give of grain, at 30 metzen (50 7^) per yoke, : 300 cwt 



'♦ « " Barley, " " 20 " (33-^) " " : 165 "

" Oats, « '* 24 to 50 lbs (401) « « : 155 « 



« " « Oats, " " 20 " (33^-) » " : 120 « 



904 " 

 These 904 cwt. must be replaced by that which the clover and the vetches have 

 appropriated to themselves from the inorganic matter. 



12.5 yokes (17-| acres,) of clover, give here, per yoke, 50 cwt. 625 cwt. 



« « «' « of manured vetches " *' 30 " 375 " 



« " « « unmanured " " " 25 " 312 « 



1312 " 

 Half of this is 656 " 



There is wanting, therefore, 248 " 



which must be replaced by fodder or litter, but in the present case may be replaced 

 by the clover roots, if the rest could only gain SO cwt., on the extent of a yoke. 



In the first example we have produced, on 100 yokes of plough land, 1,258 cwt. of 

 grain ; here only 904 cwt, because so large a part must be employed for fodder, 

 while the clover gave a smaller product, and in the sixth and eighth year the land 

 could only be cultivated for oats. 



Since, in the first volume of this work, I charged the peas-straw wholly to the 

 manure, I will therefore repeat the computation of the productions quoted on page 

 181 of that volume, (for which also see pp. 80—85 of this work) and examine how the 

 quantity of the field for fodder is proportioned to that which bears grain. We pro- 

 duce, in this mode of husbandry, in six years, in grain, on 100 yokes of plough land, 



Acres. Bushels. Metzen. 



16f yoke (23|) in Maize, at 40 metzen (67-i\) at 80 lbs. : 050-^ : 520 cwt. 

 « " « Barley, 24 " (40^) at 66 lbs. : 394f : 260 " 



« « « Winter Rye, 18 " (30f,-) at 80 lbs. : 300 : 240 " 



Peas, 12 " (20-,\) at 94 Ib.^. : 200 : 188 " 



(( 



« « « Oats, 18 " (18-iV) atSOlbs. : 300 : 150 



(( 



1358 " 

 Of clover, we produce for one yoke 60 cwt. ; consequently, of 16 1 yokes, 



1000 cwt., of this half belongs as a supply for 500 cwt 



Of peas-straw, is produced, per yoke, 30 cwt. ; consequently, of 16f yokes, 



500 cwt., of this half belongs here 250 " 



750 " 

 There is wanting, therefore, 608 cwt. addition for grain, which must be either 

 wholly or, in a great part, replaced by the clover roots. If, on the extent of one yoke, 

 only 80 cwt. of fresh roots are found, on 16| yokes there would be 1,332 cwt. ; there- 

 fore 333 cwt. of grain replaced, and there is wanting only 275 cwt. more of hay to 

 be supplied ; but, if we reckon 140 cwt. of roots per yoke, the amount supplied would 

 be 583 cwt. 



Should the clover be left out of this rotation, we should then need, for the supply 

 of 1358 cwt. of grain, as much hay ; and if the meadows gave not more than 25 

 cwt. per yoke, then there would be needed 54 yoke. 



Great harvests can only be produced by great auxiliaries, as this computation very 

 clearly shows. When, formerly, I produced on my farm, at Wolfsberg, 67 metzen 

 ( = 113^ bushels) of maize j 40 metzen ( = 67 6.10 bushels) of barley; 20 metzen
