Soil Management (Agriculture)
Soil Management Agriculture
Learn how to improve your soils and benefit from them.
This course examines:
- The properties of soil
- Testing
- How to manage and improve soil
- Soil problems
- Sustainability of soils and much more.
Soil is the foundation for profitable farming. There are many things that can be wrong with soil (eg. poor nutrition, chemical imbalance, structural problems such as drainage, lack of microbial life etc). Often minor and relatively inexpensive treatments can make a huge difference to productivity, but the problems need to be identified first, and that requires a solid understanding of soil theory and management practice.

- decide on suitable soil management strategies for the selected land
- prepare and present a report
Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.
