How You Can Use Compost As A Substrate Additive
Longwood Gardens, an 1,100-acre display garden in Kennett Square, Pa., has a compost production facility that produces more than 2,500 cubic yards of quality compost every year. This compost is used in a variety of ways at the gardens, including greenhouse production. Using compost as a substrate additive for greenhouse crops has several benefits. First, most compost is locally produced from waste products, making it one of the most sustainable substrate ingredients. This feature can also be used as a marketing tool to let consumers know they are buying a “green” product.

In most cases, small pH adjustments (0.2 to 0.6 pH units) are easily accomplished by simply changing the type of fertilizer. Large pH adjustments can be time consuming, costly and typically result from infrequent pH monitoring. The green line in Figure 1 (see page 44) represents a situation in which a grower is monitoring marigold substrate pH on a weekly basis. At week 4, the substrate pH has fallen out of the ideal pH zone and into the small corrective zone. The grower may have been using a fertilizer too acidic for the situation, and simply switching to a […]
