Gypsum offers benefits beyond sulfur and calcium (see article above) as a fall fertilizer option. "Gypsum helps improve soil structure, which leads to better seed-to-soil contact," said John Swanson, Federated agronomist at the Ogilvie location, adding there are also long-term benefits to gypsum applications:
- reduces crusting and improves germination;
- does not reduce soil pH because it is net neutral (unlike AMS, which is acidic);
- improves water use efficiency;
- helps prevent water logging in soils;
- helps plants absorb nutrients;
- decreases the bulk density (compaction) of the soil;
- increases crop rooting depth;
- decreases N losses to the air.
Additionally, gypsum's impact on the soil properties can help decrease the incidence of white mold, a significant issue this year (see article below).
Federated recommends Gypsoil™ Blendable, a consistent durable gypsum pellet that can be simply blended with other fertilizers for consistent application. "Talk to your local Federated Agronomist," said Swanson, "for more information and crop-specific use rates, as well as soil amendment use rates based on your soils."
