Empty peanut pods: calcium in the soil doesn’t walk into the peg
The peg drinks calcium from the podding layer, not from a deep band.
- The bush looks fine; dig and the pods are empty, kernels thin.
- Ask whether pegging was dry.
- Boron also hits set; empty peanut pods more often ask about calcium in the peg zone and moisture.
- Rotten fruit has lesions; empty pods were never filled.
- Don’t only spray calcium and ignore moisture; don’t lime acid peanut land without a test.
- Calcium in the peg zone: Follow a soil test and the station. Putting it where the root is beats a foliar spray
- Name what you see before you feed.
- If leaves, roots and the surface disagree, stop.
What you see in the field
The bush looks fine; dig and the pods are empty, kernels thin. Ask whether pegging was dry.First the leaf position: new or old, even yellow or between the veins. If that does not match, do not fertilise yet. Pull one plant and read whether the roots are white, brown or foul.

Why it looks like this
The field looks like this because the root cannot take water or nutrients the usual way. Fix the soil condition first — drainage, salt, acidity, compaction or a salt of fertiliser — then a thin feed. Rates live in the range on this page; confirm with a local station and the label.
Easy to mix up
Looks like “Boron shortage, flowers that set nothing”
Boron also hits set; empty peanut pods more often ask about calcium in the peg zone and moisture.
Looks like “Fruit rot”
Rotten fruit has lesions; empty pods were never filled.
Do this / don’t do that
- 1The bush looks fine; dig and the pods are empty, kernels thin. Ask whether pegging was dry.
- 2Even moisture at pegging. A little lime on acid soil from a test. Calcium in the pod layer. Drop salt first if saline.
- 3Don’t only spray calcium and ignore moisture. Use the range on this page only as a range. Confirm with a local station and the product label.
Don’t do this first
- Don’t only spray calcium and ignore moisture; don’t lime acid peanut land without a test.

Calcium in the peg zone
Follow a soil test and the station
Putting it where the root is beats a foliar spray.
Water
Even through pod set
Wet-dry swings make empty pods.
These are ranges. Confirm with your local extension station and the product label.
When you see The bush looks fine; dig and the pods are empty, test. Take soil from the bad patch and from a greener neighbour, separately.
