Hydro Terraplex
Enviroganics® Hydro TerraPlex is a natural, biological organic based fertiliser and soil conditioner that delivers excellent concentrations of nitrogen, phosphorus, potassium (2.6 – 1.2 – 2.8 + Te), sulphur, calcium, and full trace elements for 18-24 months. It also provides long-term control release fertiliser 21 – 1.8 – 9 (CRF) which minimizes leaching of nutrients and enhances microbial activity. The product meets AS4419 for soil conditioners and fertilisers.

Enviroganics® Hydro TerraPlex will be activated when watering new plantings for best results; however it can be applied dry as there is no burning or offensive smell. Enviroganics® Hydro TerraPlex has a high organic carbon 20% content to feed soil microbes and organisms it also contains 2 x long term organic wetting agents that increase the water holding capacity by up to 50% without water logging, and also increases the (CEC) cation exchange capacity.
We recommended that good quality mulch be used together with Enviroganics® Hydro TerraPlex to cover the soil surface. This will maintain an ideal environment for soil microbes and soil organisms and will reduce moisture evaporation.
