It is no secret that Seabrook has been contacting more growers to help them meet their needs. This development is a fine example of growers and processors working together in a business relationship that benefits both while satisfying the customer demand for quality product. Produced on more than 37,000 acres in the United States in 1996, spinach is confined largely to certain areas of the country. California, Arkansas, New Jersey and Oklahoma are other areas of spinach production. While most of Delmarva's processing spinach is frozen, more spinach is canned than frozen on a national scale.
Spinach is very pH-dependent.
Soils must be limed to maintain a pH over 6.0, even 6.5. Serious yield reductions can occur if the pH falls below 6.0, dropping to, say, 5.7. On sandy soils, with low-buffering capacity, the pH can drop rapidly, especially when nitrogen is applied and there is heavy rainfall. It is critical to manage the soil's acidity properly to maintain pH at 6.0 or higher. Spinach starts its reproductive stage in response to day length and temperature.
