Soil Stability for Bulb Vegetables

bulb vegetablesSoil stability relies on the strength of soil structure. Strong soil structure will contain pores that allow the passing of water and air as well as provide room for soil organisms and plant roots to move and grow. Bulb vegetables are known to have a shallow root system, and the limitations of shallow roots can be greatly exacerbated by poor soil structure.

In 1996, it was discovered that a sticky glycoprotein called glomalin has a direct correlation to strong soil structure. Glomalin is produced by symbiotic, arbuscular mycorrhizal fungi (AMF), the active ingredient found in MycoApply®. Since mycorrhizae cannot persist without a host plant, these valuable soil structure builders are depleted once plants are harvested and/or soil is tilled.

Research indicates as many as 80% of all plants species worldwide have developed symbiosis with AMF, including bulb vegetables.
The four-species consortium of AMF in MycoApply improves soil structure for bulb vegetables in two ways: it provides valuable soil penetration brought about by the fungi’s hyphae, and the beneficial fungi produce the glomalin that is fundamentally necessary for strong, healthy soils. By reinoculating root vegetables with MycoApply each season, soil health is maintained or improved, with positive effects on plants and yield.
