Land-capability Class 



One of the eight classes of land in the land-capability 

 classification, ranging from (1) land that is very good for 

 cultivation to (8) land that is not suitable for cultivation, 

 grazing, or forestry. 



Larva

 frog.

 ciated in a more or less dense growth and are interdepend- 

 ent, cf. Epiphyton. 



Laterite 



A red, highly weathered soil characteristic of damp 

 tropical regions such as equatorial Africa, cf. Laterization. 



Laterization 



Weathering which tends to produce Laterite, essentially, 

 the removal of silica and consequent increase in alumina and 

 iron oxide content, and a decrease in the Base exchange 

 capacity of the soil. cf. Podzolization. 



laurilignosa 



Laurel forests or subtropical rain forests, often with 

 Dicotyledonous and Gymnospermous dominants, cf. Lignosa. 



Layer 



The horizontal part of a community in which the plants 

 are of about the same height, e.g., tree layer, herb layer. 

 Also applicable to depth in the soil. syn. Stratum, cf. Layer-

Layerage 



The propagation of plants by inducing formation of 

 roots on stems that are attached to the plant.
