Tropical Zone Gardening: I have a mold question, 1 by AlohaHoya

Pulling up a bunch of bolted vegies from my raised bed garden today, I noticed a white mold (looked closely, not root mealies) around the root area of all the plants. A friend told me it was called 'Snow Mold' around here.

Anyone have any idea:

1. Why it happens? Are there certain conditions over others that encourage it?
2. How to get rid of it? Is it a balancing of nutrients? Adding something (lime?)?

Would appreciate any help.... I want to replenish the soil, add some chicken poop, dolomite, phosphate...but I also want to get rid of that mold!!
