There is also about 3 per cent of nitrogen. 



Q*4i©asy copra contains about 6 per cent of water, 

 2 5 per cent of ash, and 1 per cent of nitrogen. 



From these analyses it is safe to conclude that the 

 coco-nut uses both in its products and in its body a 

 conspicuously large amount of potash. The amount 

 of potash in ordinary soils is small enough, so that it 

 is a safe general conclusion that coco-nuts dependent 

 upon the local soil supply, without the continual 

 addition of fresh quantities brought by the soil water, 

 will respond to a profitable extent to the artificial 

 application of additional potash. Experiments here 

 and elsewhere indicate that this is the case. 



To a less conspicuous degree as compared with crops 

 in general, the coco-nut ties up in its own substances 

 and in its products an appreciable amount of nitrogen. 

 To a still less extent, as compared again with crops in 

 general, it removes the phosphorus of the soil. It may
