CHAPTER III 



SOILS 



Soil, or the substance in which plants are 

 grown, is composed mainly of minute fragments 

 of mineral matter and decayed vegetable and 

 animal matter. In the life history of the plant 

 it serves three purposes. First, it acts merely 

 as a medium of support in maintaining the 

 position of the plant; second, it serves as a 

 reservoir for the storing of water for the use 

 of the plant; third, it is the source of the min- 

 eral elements which go to build up the plant 

 structure. 



TYPES OF SOIL 



Soils, as considered by the florist, are of three 

 main types, namely: sand, clay and humus. 

 .Various combinations of these three types give 

 soils suitable for all plants.
