explains the increased ammonia content of the treated soils noted 

 above. 



It is clear from this investigation :that the atmosphere in and 

 around a large industrial city such as Leeds is relatively highly charged 

 with impurities, many of which exert a marked deleterious effect upon 

 plant growth. The impurities are most abundant in the industrial 

 quarters of the city, but are disseminated over very large areas, 

 especially in the directions of the prevailing winds.
