Tdble 10. Photographed on 5"^ August. 

 Tdble 10 shows the following beets: 



1. Complete manuring, with an addition of Nematodes, by means of which, it 

 was demonstrated that in the case of complete manuring, Nematodes have no 

 influence on the outward appearance of the beet. 



Manuring: 

 2.520 grams Nitrogen (N) in the form of Calcium Nitrate 

 4.230 grams Potash (KjO) in the form of Muriate or Sulphate of Potash 

 1.065 grams Phosphoric Acid (PjOs) in the form of Mono-and Di-calcic Phosphate 

 0.400 grams Magnesia (Mg O) in the form of Sulphate of Magnesia 

 1.110 grams Calcium Chloride as a protection against heart-rot and dry-rot. 



2. Manuring as in No. 1, but without Potash. The Potash which was taken up 

 by the plants in this case was very limited and originated from the sand. 



3. Manured as in N o.l, but with an addition of only 0.470 grams Potash (K2O) in 

 the form of Muriate and Sulphate of Potash. 



In the completely manured plot No. 1, the beet shows broad and juicy green leaves 

 which are not very undulating, and which, before dying, assume a pure yellow colour, 

 often on one half of the leaf somewhat earlier than on the other. They finally die 

 off a light brown colour. Where Potash is deficient (No. 2, without Potash; No. 3, 

 with small addition of Potash) the tops are relatively vigorous, and if the want is 

 not so large, then at the beginning, one can hardly distinguish them in size from
