Urea and Sulphate of Ammonia are examples of fertilisers that contain a large amount of (a)
Fertiliser is defined as:
an inorganic, manmade material containing 1 or more elements for crop growth
a natural substance spread on land to neutralise pH
an organic material of animal and plant waste spread on land
Compound fertilisers are names to represent the percentage of
Phosphorus - Potassium - Nitrogen
Nitrogen - Potassium - Phosphorus
Nitrogen - Phosphorus - Potassium
The toxic gas released from a slurry pit which can cause affixation
Carbon Dioxide
Methane
Hydrogen Sulphide
Ammonia
Soil testing should be done every
3-4 months
every second year
once year
every 4-5 years
Liming the land
Brings down pH
Increases up pH
Add nutrients tot he soil
Helps drain the soil
What is shown in the image?
(a)
Ideal soil pH is:
5.5 - 6.5
7 - 8.5
6.5 - 7.5
5 - 8
Phosphorus will only be absorbed by plants between a pH of
6.5 - 7.5
5 - 7.5
8 - 9
4 - 5
Soil samples should be taken (tick as many that apply)
at drinking troughs
away from hedges
in a 'W'
directly after liming the land
2 or 3 per field
Mary got a soil test reading of 1 for N and 4 for K this means:
Low levels of Nitrogen and sufficient levels of Potassium
High levels of Nitrogen and low levels of Potassium
High levels of Nitrogen and low levels of Phosphorus
Low levels of Nitrogen and sufficient levels of Phosphorus
Fertilisers must be stored:
in airtight containers
in hay sheds where its dry
outside near water supplies
Eutrophication is defined as:
High levels of nutrients cause aquatic creatures such as fish to die, fish are decomposed by bacteria,bacteria respire and release carbon dioxide, algae use carbon dioxide and grown excessively creating algal bloom
High levels of nutrients promote growth of algae which create algal bloom, algae die and are decomposed by bacteria, oxygen depleted, aquatic creatures such as fish die.
High levels of oxygen allow algae to respire and grow excessively, bacteria cannot survive as algae has used up oxygen, algae are not decomposed, aquatic creatures such as fish die due to build-up of algae on surface of wate

Earthworms can improve soil structure
Animals can compact the land
Animals add organic matter back into the soil
Which of the follow are a precaution when agitating slurry
Agitate when doors are open
Ensure shed doors are securely locked when agitating
Agitate slurry on your own
Agitate slurry on a windy day
Remove all livestock from the shed when agitating slurry
