NelisFert ThermoPhos - NZ's Best Phosphate Fertiliser. Total phosphorus (TP) is a measure of phosphorus in its various forms that occur in New Zealand waterways. It includes the phosphate that is stuck to sediment as well as dissolved reactive phosphorus, which is more readily available for plants.TP is an important measure because most phosphate enters our rivers bound to sediment via run-off., Treatment wetlands are a sustainable phosphorus and nitrogen removal technology which can provide cost-effective treatment, with low operational costs compared to conventional technologies. A common drawback to their application is the footprint required to support nitrification, denitrification, and phosphorus sequestration..
