Extremely fast acting high phosphorus, fossilized seabird guano that has been micronized to 1000 screen so that it is suitable for sprayers and other applications requiring a fine particle size. When placed in solution (and properly agitated) 98% will pass through a fine coffee filter. Does require tank agitation prior to and during application. Because of the fine particle size, even when applied to soil the nutrient availability will be very rapid. Work or water into soil at 5 lb/100 sq ft. Mix 1 Tsp- 1 Tbs/gallon water for foliar application.
