What is Black Gold’s Controlled Release Fertilizer?
Several Black Gold® potting soils use controlled release fertilizer formulations made with the highest quality nutrients. Our homogenous granules are encapsulated in a multilayer polymer coating. The polymer coating controls the release rate, thereby allowing a slow, continuous diffusion of dissolved nutrients to the root zone. As the soil warms up, the release rate increases consistently with the plant’s growth rate and nutrient consumption. The premium NPK formulations have a reliable release profile, which is unaffected by soil type, soil pH, moisture or microbial activity.
How do I know how much Black Gold to add?
For this, we turn to the amendment application formula. For larger loose-fill Black Gold amendments, you may want to calculate how much is needed for a given area in the garden. The following formula determines a given amount in cubic yards over a defined area:
Example: If you wanted to cover a 20-square-foot area with 2 inches of compost, the result would be: 20 ft2 x 2 inches of compost x 0.0031 = 2.48 yd3.
