Fertigation is being increasingly adopted by citrus producers as an alternative to traditional approaches to supplying fertilisers to trees.

The delivery of dissolved mineral fertilisers to the roots of crops in the field using irrigation water is known as 'fertigation'.

With recent advances in technology irrigators can now more precisely control delivery of mineral nutrients and water to the roots of perennial tree crops.

Open Hydroponics is an irrigation and nutrition management program aimed at increasing yield and fruit quality of horticulture crops.

Adopting an Open Hydroponics management program requires a reliable water supply, a significant investment in capital infrastructure, an increase in operating costs and a change in management skills.
