Project details

Objectives:

To identify the extent of responses as a result of lime addition.

Hypotheses:

Lime induces pH responses in soils.

Basis of trial

This synthesis is a collation of lime trials which have shown responses to lime addition. In some cases, these responses can be explained as molybdenum release.
