Fertilisers for Market Garden Crops. 469 



the dressings have been varied, they are not easy to take into 

 the average. 



The results are given in " sieves " of 40 lb. weight. 



In this case, as the crop is one easy to value, I give, as well 

 as the cost of the manure, the value of the sprouts, taken at what 

 is probably a fair average price, namely, is. 6d. per "sieve."

As has been said, the experience of the last three years is 

 quite confirmatory of these results, which scarcely call for com- 

 ment, as they explain themselves. 



It may, however, be pointed out that the wonderfully good 

 crops of sprouts grown without dung are grown on a plot of land 

 that has been not merely undunged for this crop, but persistently 

 undunged for any crop year after year. If we have regard to 

 the fact that every field in a market garden will, under any system 

 of cultivation, be at least intermittently dunged, the extravagance 

 of dunging specially for sprouts becomes further accentuated. 



Winter Lettuces. 

 These we have grown without any special application of dung 

 on plots which had been dunged for the preceding crop. The 

 results indicate that, if the grower has been so extravagant as to 

 use anything like 25 tons of dung per acre for the previous crop, 

 he may safely plant winter lettuces on the same land without
