    ASSESSMENT CRITERION 4 
    The value of organic material in topsoil is explained in respect of the positive contribution that this has on the soil's water retention. 

    ASSESSMENT CRITERION 5 
    The value that topsoil has for the establishment and growth of plants is explained in respect of the nutrient content of the organics. 

    SPECIFIC OUTCOME 2 
    Identify the main soil types and describe their major characteristics. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The characteristics of sandy soils are described in respect of their physical and other distinguishing features.

    ASSESSMENT CRITERION 3 
    The characteristics of clay soils are described in respect of their physical and other distinguishing features. 

    ASSESSMENT CRITERION 4 
    The main soil types are identified and the significant differences are indicated according to theory. 

    SPECIFIC OUTCOME 3 
    Recognise the role that water plays in cultivated soils and the factors that influence the infiltration rate in the different soil types. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The necessity for a presence of water in the soil is described in terms of the role that water plays in the maintenance of soil fertility and plant growth. 

    ASSESSMENT CRITERION 2 
    The determination of the ratio of macro and micro pores is explained in respect of the texture and soil types. 

    ASSESSMENT CRITERION 3 
    The variance in the infiltration rates of different soils is explained in respect of the influences of their pore spaces and structure. 

    ASSESSMENT CRITERION 4 
    The influence that organic matter plays in a soil is explained in respect of the enhanced water retention and infiltration. 

    ASSESSMENT CRITERION 5 
    The effects that poor infiltration rates are explained in terms of the drainage, aeration and suitability for planting. 

    SPECIFIC OUTCOME 4 
    Explain the role that capillary action plays in the transference and storage of water in the soil. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Capillary action is defined in terms of the forces that cause water movement in the soil. 

    ASSESSMENT CRITERION 2 
    The effects of capillary action are described in respect of the ability of water to be transferred both horizontally and vertically in the soil. 

    ASSESSMENT CRITERION 3 
    The effects of capillary action are described in respect of the ability of water to be transferred both horizontally and vertically in the soil. 

    ASSESSMENT CRITERION 4 
    The influence that the ratio of micro to macro pores in a soil has on capillary action is explained in terms of the potential that the various pores have for water transference. 

    ASSESSMENT CRITERION 5 
    The benefits that capillary action provides for plants are described in respect of the improvements in water and nutrient retention. 

    SPECIFIC OUTCOME 5 
    Explain the role that aeration plays in the maintenance of soil fertility and the factors that cause poor aeration. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The process of aeration is defined in terms of the gaseous exchange that occurs in the soil. 

    ASSESSMENT CRITERION 2 
    The aeration potential of the different soil types is characterised in terms of their pore spaces and compaction levels. 

    ASSESSMENT CRITERION 3 
    The primary functions of soil aeration are explained with respect to the maintenance of soil fertility and beneficial micro-organisms. 

    ASSESSMENT CRITERION 4 
    The detrimental results of poor aeration are described in terms of the low nutrient intake and presence of organic toxins in the soil. 

    ASSESSMENT CRITERION 5 
    Factors that contribute to the reduction of the soil's aeration are explained in terms of over watering and compaction. 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner or moderating the assessment of a learner against the qualification must be registered as an assessor with the relevant Education, Training, Quality, Assurance (ETQA) Body, or with an ETQA that has a Memorandum of Understanding with the relevant ETQA.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
