Potassium Flashcards
1
Q
Potassium- function
A
Photosynthesis
Regulates the opening and closing of the stomata
ATP production
Increases root growth
2
Q
Potassium- highest demand
A
From germination to tillering as it is vital for root establishment
3
Q
Potassium- deficiency
A
Yellowing of the leaves
Plant growth is retarded
Stalks are weakened
Uneven ripening
4
Q
Potassium- factors that reduce availability
A
Low levels of organic matter
Sandy soils – prone to leaching
5
Q
Potassium- management
A
Soil testing
Tissue testing
Paddock drainage
Increase organic matter
