Nutrient Supply from Organic Amendments Applied to Unvegetated Soil, Lettuce and Orchardgrass

The nutrient-supplying potentials of poultry manure compost (PM), feather meal (FM), alfalfa meal (AA) and vermicastings (VC), and an unamended control in a growth room experiment were measured. The amendments were applied at rates equivalent to 200, 400, and 800 kg total N ha super(-1) to a soil of...

Description
Summary:The nutrient-supplying potentials of poultry manure compost (PM), feather meal (FM), alfalfa meal (AA) and vermicastings (VC), and an unamended control in a growth room experiment were measured. The amendments were applied at rates equivalent to 200, 400, and 800 kg total N ha super(-1) to a soil of low fertility. Amendments and combined root and shoot samples were finely ground for total C and total N determination using an automated LECO super( registered )CNS Analyzer. The experimental units were pots placed at four location blocks in a growth chamber and treatment combinations were completely randomized in each block. It was found that the VC treatments supported the highest lettuce biomass production.
