    What You Will Do

    • Investigate what is being done for improving agricultural sustainability in your country or region.
    • Contact different organisations or farmers and find out what you can about attitudes & resources available to assist with improving sustainability in your chosen area/Country/region.
    • Investigate whether an organic certification scheme operates in your country, and if so, find out what is involved currently in attaining that certification for a farm.
    • Obtain either literature or advice relating to the management to soil degradation in your locality.
    • Identify the most important issues that farmers need to address in a region within approximately 100 km( or 50 miles )of your home; in order to remain financially viable over the next two decades
    • Distinguish between hydroponics, permaculture, biodynamics and certified organic farming.
    • Identify a farm situation where it might be appropriate to convert to either permaculture, biodynamics or certified organic system.
    • What is being done to improve sustainability of agriculture in the region, country or state of your choice.
    • Obtain information from your local government department or irrigation supply company. Find out what the local water quality is like and how it was measured.
    • Explain how you can test your local water supply for contaminants. What contaminants were found? eg. Bacteria, heavy metals, silt etc.
    • Outline how can these contaminants be removed from the local water supply eg filtration, chemicals, etc.

    Organic Matter Improves Soil


    Soil is a combination of inorganic material (particles of varying sizes derived from broken down rock), mixed with organic material (particles derived from living things that have died and decomposed). The organic material is largely responsible for making a soil fertile; insulating the soil against extremes of temperature, and holding moisture during dry periods; among other things.

    Sustainability starts with Soil Health.

    By knowing and understanding where this organic material comes from; you can manage the sustainability of your soil; ensuring that there is a supply of new organic matter as the old organic matter continues decomposing and it's nutrients continue being absorbed into plants. Some of these Organic Sources include:

    Cover Crops

    Farms often grow a crop to simply plow it in. On the surface, this may seem counter productive; but doing this may be the difference between maintaining adequate levels of organic matter in a soil, and not. One of the best crops to use for this purpose would be a "legume". You will learn more about why legumes are so valuable in this course.

    Logs and branches of trees
    Whole logs can be levered together and used as planting sites. They break down rapidly due to rain, heat, termites, and fungi. In Hawaii, rotting logs of the kukui tree (Aleurites moluccnesis) are placed in shallow water of taro terraces. An edible fungus appears on the logs and is used as crop.

    Detritus from bamboos and pines:
    Several plant species provide silica-rich mulch (palms, bamboos, Casuarinas). This can be used at the base of newly planted trees. This silica has the effect of reducing pH.

    Aquatic weeds:
    These are excellent crop mulch. Useful plants include:
    The water lettuce (Pistia), water fern (Azolla), water hyacinth (Eichornia), algal mats, reeds, and rushes

    Crop wastes and manures:
    The husks of corn, kitchen wastes and human and animal manures are useful tropical garden mulches. Cardboard and newspaper are valuable for suppressing grass growth.

    Hedgerow and mulch plants:
    All hedgerows are continual mulch sources (Hibiscus, Casuarina, banna grass, palms, Acacia). Other species of good mulch value are: Nicotiana, wild ginger, lemongrass, bamboo (leaves), vetiver grass, sesbania, soft ground legumes, and comfrey.
    A top mulch of straw, bark, dry manure, or woodchips is added annually or whenever needed. It is also essential to interplant leguminous green crops (perennial and annual) within the garden to help add nutrients to the soil.
    The value of mulch in weed suppression is a major factor in decreasing work in the garden. Mulch should be applied at 20-25cm deep when first establishing home gardens.
    Coconut husks have a variety of uses, not the least of which is as mulch for a valued crop such as vanilla orchids. Shredded bark and broken shells are ideal mulch for ginger, turmeric and vines.
    There is no reason for burning organic wastes in the tropics as even large materials rot quickly due to fungi, termites, and beetle larvae. Logs also provide slope barriers against monsoon erosion.
    It is possible to grow in poor tropical soils but it requires a lot of early work in rehabilitating the soil in order to render it useful and efficient.

    How this Course Might Benefit You

    Any farmer or even hobby farmer who has not studied sustainable agriculture before, will expand their knowledge, understanding and awareness of how to better manage their property.

    This course may also lead and help you in many other ways as well though. Anyone who works in agriculture needs to understand sustainability. This can range from those who provide materials, equipment and services to farms, through to the agriculture media and education sectors. You may use this course to supplement past studies and experience. Others may use it as a foundation, continuing and building on what you learn here, with further study beyond this course.
