1 -SQA- SCOTTISH QUALIFICATIONS AUTHORITY Hanover House 24 Douglas Street GLASGOW G2 7NQ NATIONAL CERTIFICATE MODULE DESCRIPTOR -Module Number Session Superclass- SL -Title- LIVESTOCK WASTES AND EFFLUENTS (x 1 / 2 ) -1- -DESCRIPTION- Purpose This module is designed to enable the student to select farm waste disposal systems with due regard to environmental and agricultural considerations. It is aimed at those who wish to develop their abilities at craft level within the land-based sector. Preferred Tractor Operation 2. Entry Level Outcomes The student should: 1. calculate the quantity of farm wastes produced by different farm enterprises; 2. describe systems for the collection, storage and disposal of farm wastes; 3. describe the physical, legal and environmental considerations associated with farm wastes; 4. operate a system of waste handling and disposal. Assessment Procedures Acceptable performance in the module will be satisfactory achievement of all the Performance Criteria specified for each Outcome. The following abbreviations are used below: PC Performance Criteria Instrument of Assessment

2 Note: The Outcomes and PCs are mandatory and cannot be altered. The may be altered by arrangement with SQA. (Where a range of performance is indicated, this should be regarded as an extension of the PCs and is therefore mandatory.) OUTCOME 1 CALCULATE THE QUANTITY OF FARM WASTES PRODUCED BY DIFFERENT FARM ENTERPRISES PCs (a) The calculation of the quantity of animal wastes is accurate for a group of livestock. (b) The calculation of the quantity of effluent produced from a given quantity of silage is accurate. Assignment The student will be set an assignment which tests the application of knowledge and skills required to calculate the quantity of farm wastes produced by different farm enterprises. The assignment will centre on a specific farm situation and will cover the following: (i) (ii) (iii) (iv) calculation of the quantity of animal wastes produced from a group of cattle; calculation of the quantity of animal wastes produced from a group of sheep; calculation of the quantity of animal wastes produced from a group of pigs; calculation of the quantity of effluent produced from a quantity of silage. on all the Performance Criteria being met. OUTCOME 2 DESCRIBE SYSTEMS FOR THE COLLECTION, STORAGE AND DISPOSAL OF FARM WASTES PCs (a) The description of waste collection in a range of systems is comprehensive in terms of equipment used and the drainage arrangement. (b) The description of waste storage in a range of systems is comprehensive in terms of types of store and handling methods. (c) The description of waste disposal in a range of systems is comprehensive in terms of equipment used. -2-

3 Restricted Response Questions The student will be set restricted response questions which test the application of knowledge and skills required to select systems for collection, storage and disposal of farm waste. The exercise will consist of 12 restricted response questions allocated as follows: (i) Performance Criterion (a) 4 (ii) Performance Criterion (b) 4 (iii) Performance Criterion (c) 4 on correct responses as follows: (i) 3 out of 4 (ii) 3 out of 4 (iii) 3 out of 4 OUTCOME 3 DESCRIBE THE PHYSICAL, LEGAL AND ENVIRONMENTAL CONSIDERATIONS ASSOCTED WITH FARM WASTES PCs (a) The identification of the physical constraints of the application of farm wastes is comprehensive in terms of quantity and timing. (b) The outline of current legislation and codes of practice is correct and complete. (c) The identification of the environmental implications is comprehensive in terms of pollution prevention. Restricted Response Questions The student will be set restricted response questions to test the application of knowledge and skills required to describe the physical, legal and environmental considerations associated with farm wastes. The exercise will consist of 12 restricted response questions allocated as follows: (i) Performance Criterion (a) 4 (ii) Performance Criterion (b) 4 (iii) Performance Criterion (c) 4 on correct responses as follows: (i) 3 out of 4 (ii) 3 out of 4 (iii) 3 out of 4-3-

4 OUTCOME 4 OPERATE A SYSTEM OF WASTE HANDLING AND DISPOSAL PCs (a) The procedures in preparing equipment are in accordance with good farm practice. (b) The operation of equipment is in accordance with good farm practice. (c) The spreading of the waste material is in accordance with good farm practice. (d) The maintenance of the equipment on completion of the task is in accordance with the manufacturer's instructions. Practical Exercise The student will be set a practical exercise to test the application of knowledge and skills required to operate a system of waste handling and disposal. The student will be expected to carry out the procedures specified in the Performance Criteria on one occasion. The assessment should be carried out with the aid of an observation checklist. on all the Performance Criteria being met. -4-

5 The following sections of the descriptor are offered as guidance. They are not mandatory. CONTENT/CONTEXT Safety regulations and safe working practices and procedures should be adhered to at all times. Corresponding to Outcomes 1-3: 1. The estimation in gross terms of the quantities of wastes associated with cattle, pigs, poultry and sheep, housed in a variety of different situations. Estimation of silage effluent production. Washings from milking parlour and associated buildings. Disposal of sheep dip. 2. Describe the systems and equipment used in the collection, storage and disposal of livestock wastes (covering: yards, slats and scraper systems). Waste should include both farmyard manure and slurry (and other farm effluents) under the following headings: (a) (b) (c) collection e.g. tractor/mechanical scrapers, power hosing, tractor/industrial loaders (fork lift, skid steer), drainage arrangement. storage (mixing where applicable) e.g. midden, underslat pits, storage tanks. handling and disposal of: (i) (ii) solids - spreaders; slurry - tankers, irrigation, separation. 3. Quantities of waste produced; seasonality of production; conditions suitable for storing and disposing of farm wastes. Application rates; timing of applications in relation to cropping and crop rotations. Legislation and codes of practice. Environmental aspects - pollution - run off, eutrophication, odour, toxicity. 4. The operation of machinery and equipment necessary for handling waste from stock to field. Students should handle and dispose of either solid, semi-solid or liquid waste. -5-

6 SUGGESTED LEARNING AND TEACHING APPROACHES Relating to the Outcomes: The student should extract information from library resources, including standard texts and bulletins, whilst undertaking assignments. Visits should be arranged to enable students to observe a range of systems. Special attention should be given to the operating principles of associated machinery. The timeliness of fieldwork is also important. Visits could be supplemented by illustrated discussions in the classroom/lab and workshop exercises. Students should get practical experience of the operation of one or more of waste collecting, storage, handling and disposal systems. Copyright SQA
