Cabbage Transplant Production Using Organic Media, 2008
Rangarajan, Anu; Leonard, Betsy; Jack, Allison
INTRODUCTION: Successful transplant production begins with good growing media. Healthy vigorous transplants will be less susceptible to insects, diseases and transplant shock leading to better crop performance. Formulating organic potting mixes is especially challenging. Organic sources of nitrogen such as compost can be inconsistent. Compost can change over time with storage and N release can be unpredictable. Many organic potting mixes are supplemented with nitrogen sources such as alfalfa meal, soybean meal and blood meal. An alternative to compost is vermicompost. Vermicompost is thought to be a more soluble nitrogen source as an amendment for organic potting media. Past research in the Rangarajan lab has shown improved yield with vermicompost compared to thermophilic compost. The object of this project is to create an improved potting media for organic vegetable transplant production. Here, we tested six different potting media for growth and productivity of cabbage.
