Aim
MODULE 2 - ORGANIC NUTRIENT SOURCES
To understand the role, value and nature of organic nutrient sources.
2.1 Competence
Candidates must be able to describe the different types of organic nutrient sources, the storage, handling
and spreading properties and understand the issues involved in measuring the nutrient contribution of the
materials.
2.2 Performance Criteria
Candidates must be able to:
• appreciate the characteristics, analysis, and the short and longer term availability of nutrients
contained in
a) farm yard manures
b) poultry manures
c) sewage sludge/cake
d) liquid manures/slurries
e) composted organic materials
f) green manure crops and other organic materials
when related to specific cropping situations
• appreciate factors influencing the nutrient value and plant availability of the above organic materials
• understand how to prepare a manure management plan and to calculate manure/slurry storage
requirements.
• demonstrate an awareness of spreading techniques and pollution hazards arising from utilising organic
materials
2.3 Essential Knowledge & Skills
Candidates must have the ability to:
• explain the methods/devices for measuring the nutrient content of organic nutrient sources and
application of the materials to land
• interpret an analytical report for an organic nutrient source and explain the difference between total
and readily available nutrients
• explain the main options for improving the management of organic nutrient sources to optimise
nutrient uptake by crops and grass (eg. timing and method of application)
• describe the different methods for applying organic nutrient sources and explain their relative benefits
• describe the pathways through which nutrients may be lost to water or the air during storage and
before/after application of organic nutrient sources
• demonstrate competence in advising on rates and timing of applications in relation to soil type and
prevailing patterns of rainfall distribution
