Nitrate of Soda (NaNO3)
If your soil is deficient in nitrogen, the only rock mineral fertilizer to use is nitrate of soda (16-0-0), which can also be called sodium nitrate. The mineral nitrogen, mined from the Atacama Desert in Chile, is almost immediately available to plant roots.
- A fast acting nitrogen fertiliser for beetroot, celery and other leafy crops.
- Apply as required during the growing season.
- Can be applied as a top dressing or a liquid feed
- It is short-lived in soil, so it is best applied just before planting time.
- Apply 4 pounds per 1,000 square feet.
- The fertilizer increases both sodium and soil pH - 1 pound of sodium nitrate raises pH about as much as 3 pounds of lime would.
- Hi-Yield Nitrate of Soda is a fast acting, non-acid forming source of nitrogen when growth and color are needed quickly.
- Nitrate of Soda should not be applied to heavy clay soils as it makes them harder to work.
