Testing of Seaweed By-Products for Enhanced Growth in Young Apple Trees (1998)

Summary:

Some seaweed products and constituents are known to stimulate plant growth through several potential mechanisms. Growth trials using a seaweed processing by-product were conducted in Washington apple orchards, in 1997 and 1998. Plant growth and yield benefits at the end of two growing seasons resulted in non-significant differences between the seaweed plots and unamended plots.
