Understand the Importance of Soils

Soil is the medium for horticulture and agriculture in which we grow gardens, crops or pastures to raise stock and from which we extract minerals and fuels. Soils is also the largest sink and source of carbon through its organic matter store (~1.5 x 1012 tonnes of carbon), and is therefore important in global carbon cycling. Additionally, groundwater under soil comprises one of the largest reservoirs of the freshwater.

Learn about the factors that cause land quality to degrade, and the measures that can be taken to counter these issues and repair damaged land.

Learn to Attend to Soils

Soil degradation has caused the downfall of many societies in the past, including severe wind erosion and desertification in the ‘dust bowl’ in USA; desertification and salinisation around the Aral Sea in Central Asia and salinisation, erosion and siltation in ancient Mesopotamia.  Often, there has been an emphasis on using the soil for production of crops/grazing from soils at the expense of their sustainability.  Soil resources are treated as limitless when in fact they are not renewable or are so called very slowly-renewable (in some cases they are renewed at an infinitesimal rate far greater than soil losses). Estimates for rate of soil formation are usually between about 50 to 500 years to make 10 mm of soil.     

On a global basis, the soil degradation is caused primarily by:

  • Overgrazing (35%) 
  • Agricultural activities (28%) 
  • Deforestation (30%) 
  • Over-exploitation of land to produce wood for fuel (7%) 
  • Industrialisation (4%)  

Over recent decades there has been increasing concern about soil degradation due to chemical pollutants from human activity. With a growing awareness, there is an emerging and rapidly expanding industry concerned with responding to these issues.

This course can enlighten and inform you to become part of that move to stem land degradation and begin to counter the mistakes ofd the past.

 

START ANY TIME AND WORK THROUGH THIS COURSE AT YOUR OWN PACE

At only 20 hours. this is different to our other 100 hour courses; being not only shorter and with a lower fee, but with the assessments at the end of each lesson being fully automated.

At the end of each lesson, you are given a short interactive test to undertake, to provide an indication of how your learning is progressing. 
You have access to a help desk for support from a horticulture tutor if you need it in any point in your studies.

When you finish the final lesson, you are given a more thorough automated test or examination. If you achieve an overall pass; in this final online test; you are provided with an electronic copy of a  'Certificate of Completion', with your name and the course name and date, to print and store electronically in your permanent records.

 

Who Will Benefit From Doing This Course?

  • People working in land rehabilitationand reafforestation
  • People working on the rehabilitation of mining sites
  • People interested in working on environmental projects
  • People who work with soil on a daily basis
