Subtrate microbiome of container grown Impatiens Walleriana
We investigated the effects of phenological stage and fertilization levels on the bacterial communities of peat-based substrate (80% peat and 20% perlite) used in greenhouse ornamental production. The substrate samples were collected from container-grown Impatiens walleriana Xtreme Red. Plants were fertilized with 15N-0P-12.5K-2.9Ca-1.2Mg water-soluble fertilizer at low (25 mg/L N), optimum (100 mg/L N) and high (200 mg/L N) levels. Samples were collected at budding (four weeks after transplant) and full flowering (eight weeks after transplant).
