Green Machines

Synopsis: Food production is a highly technical business. This programme looks at long-term sustainability in farming. Looks at the basic scientific principles of plant growth - the balance between nutrient and energy supplies. Looks at crop rotation, cultural methods to control pests, soil erosion, and at how applications of fertiliser and pesticides are carefully monitored, using a Wiltshire farm as a study example. Also looks at soil analysis techniques in a modern laboratory.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
