Quiz - Summing up composts, fertilisers and mulches
You're making good progress; that's Module 3 done. You might like to recap what we have covered so far and also you might like to consolidate what you learnt. Just a reminder that the quiz is not recorded anywhere, and it is not a pre-requisite to moving to the next module.
In order to grow food successfully we discovered in Module 3 we need to provide adequate nutrition to plants and the conditions that will maximise growth and performance. Composts, fertilisers and mulches are vital to growing healthy productive plants.
Question 1
When you are composting and you don't have enough carbon, what type of odour will your compost give off?
Question 2
What is the recommended carbon to nitrogen ratio for composting?
Question 3
During decomposition, the microbes working away generate heat, which is why composts are hot, especially in the early stages. What is the ideal temperature for compost to break down?
Question 4
How do you get the right carbon and nitrogen ratio of material for making a compost? Do you...
Question 5
What makes organic fertilisers slower in releasing nutrients to the soil compared to synthetic fertilisers?
Question 6
What does NPK - the major or macro nutrients found in fertilisers stand for?
Question 7
Mature fruit trees can be quite hungry. How many kilograms of fertiliser do they need once established?
Question 8
Cover crops are a practice that has been used for centuries by farming communities. What are the benefits of gardening this way?
Question 9
What are the three main benefits of using organic mulches?
Question 10
Lowering soil pH (the acidity of soil) is a complex business. What can you add to your soil to reduce the pH level?
