RAW Plant Nutrition Book

Organic yucca extracts are also a valuable addition to compost teas and other microbial inoculants. Since yucca contains complex sugars, it is a stable carbon source for plant-growth-promoting microorganisms in the root zone. Microorganisms convey many benefits to plants, including the mineralization of organic matter, improved root growth and induced resistance to pests and disease. So over time and with continuous use, yucca will help stabilize soil pH, decrease soil compaction, and increase the availability of essential trace elements to the roots.

YYucca extracts are sometimes added to concentrated nutrient formulas, especially when mixing mineral salts with organics. Yucca helps keep minerals and organics in suspension with each other in concentrated form. Sometimes the higher molecular weight organic molecules tend to settle out of solution. But if the solution contains yucca, a quick shake will disperse everything back into suspension for the perfect blend. Yucca extracts foam when shaken or vigorously stirred, though, so yucca is usually added to the mixing tank last.
