What do you see and when?
- Small, stunted or dark green leaves on sub-clover plants
- Observed in early spring when clover is adequately growing
What could this indicate?
- Phosphorus deficiency. Only when phosphorus deficiency is extreme do leaf symptoms appear
- Slow and poor growth of pasture occurs from “hidden hunger” of all nutrients before appearance of leaf symptoms. Sub-clover leaves with adequate fertility should be the size of a 20 cent piece.
What test can I do to confirm?
