Rhs year 2 week 4 presentation 2012

  1. 1. RHS Level 2CertificateBarriers to Learning and Soil OrganicMatter
  2. 2. Learning objectives Identify two ways to improve personal time management for study. Identify two techniques to overcome negative attitudes to study 5.1 State the main sources of organic matter in the soil, to include: recycling of natural resources (plant and animal remains); incorporation of imported resources, e.g. farm-yard manure and garden compost; incorporation of crop debris. 5.2 Describe TWO beneficial effects and TWO limitations of organic matter in the soil. 5.3 List four bulky organic materials that can be used for soil improvement in a garden, including farmyard manures; garden compost; mushroom compost; composted municipal waste. 5.4 Compare the benefits and limitations of each of the materials listed in 5.3 for soil improvement.
  3. 3. Soil Profile and TextureHomework outcomes In groups discuss outcomes and complete the forms. How would you manage the soils you have identified? Water, drainage, organic matter, structure? What are the variations across the district? Any anomalies – ‘builders top soil’, cultivation pans etc.
  4. 4. Study Planning and TimeManagement Four D’s – Do It! Delegate it! Dump it! Do it less well! Written Study plan Family support (see Delegate it!) Rewards and motivation – watch out for the ‘fifth week blues’
  5. 5. Barriers to Learning Negative beliefs about ourselves as learners How to challenge these? I can’t do this….yet! Fear of failure How to overcome this? Focus on the positive.
  6. 6. Soil Organic Matter Natural cycle of deposition and decomposition interrupted by harvesting, weeding and cultivation Without additional organic material the soil becomes depleted. Sandy soils lose organic matter more quickly than clay soils. Decomposition needs air and the speed is temperature and moisture dependent.
  7. 7. Main Sources of OrganicMatter in the Soil Natural decomposition of leaves and plants and animals after death. From the garden – digging in crop residues; garden compost Brought in materials – mushroom compost; municipal composted garden waste; farm yard manure.
  8. 8. Advantages and disadvantagesof crop debris etcAdvantages DisadvantagesPresent on site Unlikely to bealready sufficient on its ownNo risk of importing Turning in weeddiseases seeds that will germinate if exposed to lightLow effort – digging in Soil may then containonly very coarse organic matterRecycles waste
  9. 9. Advantages anddisadvantages of compostAdvantages DisadvantagesLow cost – either free Local authorityor purchased from LA compost may contain plastics, perennial weeds etcGood source of May contain pests andnutrients diseases if not ‘hot’ compostedRecycles waste that Uncertain nutrientwould otherwise be composition.dumped
  10. 10. Advantages and disadvantagesof Farm Yard ManureAdvantages DisadvantagesLong lasting in the soil Needs to be stacked and storedGood source of Uncertain nutrientnutrients compositionGood for improving Can contain herbicidedrainage residuesEasily available and Can acidify soil;inexpensive in bulk anaerobic decomposition causes foul smell
  11. 11. Advantages and disadvantagesof spent mushroom compostAdvantages DisadvantagesRecycles waste Not readily available in many areasAlkaline so good for Alkaline so not goodvegetable plots for acid loving plants, fruit etcGood organic content Can be expensive dueand already partially to transport costsrotted – no need to unless collected.stack.
  12. 12. Advantages and limitations ofadding organic matter to thesoilAdvantages LimitationsImproves drainage and Needs to be regularlywater holding capacity applied in bulk – especially intensively cultivated soilsEncourages formation of Breaks down more‘crumb’ structure quickly in well aerated, well drained soilsDarkens soil so it warms Can acidify the soil as itmore quickly decomposesImproves CEC Likely to need to import material
  13. 13. Learning outcomes Identify two ways to improve personal time management for study. Identify two techniques to overcome negative attitudes to study 5.1 State the main sources of organic matter in the soil, to include: recycling of natural resources (plant and animal remains); incorporation of imported resources, e.g. farm-yard manure and garden compost; incorporation of crop debris. 5.2 Describe TWO beneficial effects and TWO limitations of organic matter in the soil. 5.3 List four bulky organic materials that can be used for soil improvement in a garden, including farmyard manures; garden compost; mushroom compost; composted municipal waste. 5.4 Compare the benefits and limitations of each of the materials listed in 5.3 for soil improvement.
