Question Name some common Organic fertiliser types. Fertiliser types

Back (Answer)

• Seaweed • Mushroom compost • Farmyard manure • Chicken litter The content can be variable, depending on animal feeding practices. Fertiliser types

Front (Question)

Question How are Inorganic fertilisers produced? Fertiliser types

Back (Answer)

• They are synthetically produced or are from quarried material such as limestone. These products have a predictable nutrient content. Fertiliser types

Front (Question)

Question Inorganic fertilisers can be described as ‘straight’ or ‘compound’. What does that mean? Fertiliser types

Back (Answer)

• Straight fertilisers contain one main nutrient, eg urea (nitrogen), Superphosphate (phosphorus). • Compounds contain a number of elements at different percentages, typically NPK and sometimes trace elements. Fertiliser types

Question What is Liquid Feeding? Liquid Feeding

Back (Answer)

Used in nursery production systems. Proprietary feeds are more expensive but more convenient Various formulations Eg: 18:10:18 or 14:10:30 Liquid Feeding

Front (Question)

Question Various systems exist for irrigating and liquid feeding. What are they? Liquid Feeding

Back (Answer)

Irrigating systems * Capillary irrigation * Drip irrigation * Overhead spray systems Liquid Feeding

Front (Question)

Question What is Capillary irrigation? Liquid Feeding

Back (Answer)

Capillary irrigation * Layer of sand or matting, water is drawn into compost by capillary action. Beds/benches must be level. Salts can build up in matting. Liquid Feeding

Front (Question)

Question What is Drip irrigation? Liquid Feeding

Back (Answer)

Drip irrigation * Individual drip line into each pot from a main line. Useful for pots over 7 litres (capillary action is less efficient at larger pot sizes). Liquid Feeding

Front (Question)

Question What is Foliar feeding? Liquid Feeding

Back (Answer)

Foliar feeding * It is taken up by stomata or through the leaf cuticle. * Used to supplement and correct deficiencies of trace elements. Liquid Feeding

#12

Front (Question)

Question What precautions should we follow when Foliar feeding? Liquid Feeding

Back (Answer)

Foliar feeding precautions * Needs to be precisely controlled to avoid ‘burning’ the leaves. * Dilution rates are critical. * Application in direct sunlight should be avoided. * Not as cost effective, large amount of nutrients drip off or washed away. * Used in hydroponic systems. Liquid Feeding
