Kelp As A Fertilizer

Are there ill effects from using sea kelp as a fertilizer for orange
trees?
There is no ill effect. Sea kelp has been dragged from the beaches at
low tide, partly dried and used, for centuries perhaps, as field
fertilizer for all sorts of crops in Europe, and for decades, to some
extent, on the New England coast. The dangerous substance in it would
seem to indicate that that is not present in sufficient quantity to
cause trouble. The great difficulty lies in securing and transporting
the substance, for less than its fertilizing equivalent can be obtained
by purchase of other more concentrated manures.
