CONTEXT
Soil analysis: from understanding indicators to developing a diagnosis
This training is a continuation of the course entitled "Understanding and value easily the soil analysis to increase its fertility”. In this first part, the learner was able to:
-
Learn how to take a soil sample for laboratory analysis,
-
Become familiar with each soil analysis indicator, particularly its agronomic dimension, its order of magnitude, and how to interpret it,
-
Discover three support tools, with their functionality illustrated using the results of the soil analyses they provided,
-
Understand how soil fertility is built and what its indicators are,
-
Know how soil analysis fits into the assessment of soil fertility and be aware of complementary tests.
The objective of this second part is to enable the learner to link the indicators together to build a comprehensive diagnosis of the soil’s mineral functioning. This first step should then allow them to formulate concrete solutions to adjust agricultural practices accordingly

OBJECTIVES
Become Independent in developing a diagnosis to formulate agronomic solutions

UNDERSTAND
how is soil fertility built, and what are its indicators

KNOW
how soil analysis is positioned in the assessment of soil fertility and knowing the complementary tests

KNOW HOW TO ADAPT
consequently, their practices to increase soil fertility

KNOW HOW TO DEVELOP
a complete diagnosis and formulate agronomic recommendations

KNOW HOW TO APPLY
diagnostic techniques on concrete examples

PUBLIC CONCERNED
All public

-
Macro and trace elements: contents, needs and interactions
2. Know how to build a diagnosis form soil analysis results
-
Respective interaction of soil analysis indicators
-
Interpretation of deviations from the average
-
Simple techniques for building a diagnosis and formulating agronomic recommendations
3. Group work around their respective soil analyses
-
Study of soil analyses brought by each participant
-
Handling of diagnostic support tools
-
Construction of a complete diagnosis from the results of each soil analysis
-
Development of agronomic recommendations to adapt agronomic practices
4. Presentation of group work and interactive discussions on the resultss
