We will discuss all the concept and information about soil here to
find out how This can be explored with all its component and
properties to be used in a Digital system.

I want peoples to share knowledge about soil like
soil types,
soil properties,
factor affecting soil fertility,
soil health improvement techniques,
soil suitability for particular crop
and everything about soil which affect agriculture.

you all are welcome to join the discussion to share the knowledge and
ask queries to be answered by other expert group members

while searching for soil type: I come across a classification as
follow:
==
Alluvial Soil
Black Soil
Red & Yellow Soil
Laterite Soil
Arid Soil
Saline Soil
Peaty and Organic Soil
Forest Soil
==
is this a right kind of soil classification which cover all type of
farmland and easily give us details and properties of soil that can be
used by any software.

I want to know that according to various properties and
characteristics of soil regarding agriculture what classification of
soil is most suitable, please share that knowledge with us here.

Thanks.
