HoloPhos™

A superior form of phosphorus

Price range: $39.52 through $1,389.32
Product details
Phosphorus is an essential nutrient for the transport of the energy created in photosynthesis. Many chemical sources of phosphorus either leach quickly out of the root zone or bind up in soil and become unavailable to the plant. They also negatively impact soil fungal populations. Unlike many other phosphorus sources, HoloPhos works within the biological system to be available when plants need it, and to promote microbial activity rather than to shut it down.  This product is not available in California. Product availability varies due to state-by-state product regulations. Please check availability in your state here.

Holo-K™

Fast-acting potassium to improve fruit quality and storability
Price range: $53.44 through $8,909.44
Product details
Holo-K provides a strong, immediate source of potassium that remains available in soils. A generous supply of potassium after the cell division stage is needed to develop large, firm fruit without defects. Low potassium levels at that time will result in smaller fruit or grain kernels, lightweight fruit, and many other fruit quality and storage problems.  This product is suitable for use under NOP. Please check with your certifier before using. Product availability varies due to state-by-state product regulations. Please check availability in your state here.
