Summary
The effects of applying dry meals from the seaweedsPachymenia himantophora andDurvillea antarctica on the inorganic nitrogen metabolism and microbiological activity of soils has been investigated. Glasshouse trials have shown that plants grown onDurvillea-treated soil suffer from nitrogen deficiency which can be reversed by the addition of ammonium nitrate. Both the seaweeds, and in particularDurvillea, were found to immobilise inorganic nitrogen in soils. This removal of available nitrogen is considered to be due to the greatly stimulated microbiological activity shown to take place following seaweed treatment.
