Abstract
The New Zealand vegetable and flower greenhouse industries have largely converted to automated greenhouses using soilless media.
A key environmental issue is the sustainable disposal and use of surplus nutrient solutions.
The industry commissioned a study to investigate how the water and nutrients in the solutions could be turned into a resource.
Application to pasture was selected as the most sustainable option as it has high plant cover and grows year round in New Zealand’s temperate climate.
A difficult period is winter when slower growth, low nitrogen uptake, high rainfall and low evapotranspiration can make sites unsuitable to receive solutions for several months.
The recommendations in the study are based on seasonal pasture growth rates and the Lincoln University Nitrogen Leaching Estimation Model.
These show it is environmentally safe to make regular releases to pasture of up to 30 kg N per ha every 21 days, without causing nitrate pollution of groundwater or waterways, provided the site is in a suitable condition.
The critical conditions are soil moisture deficit and growth rate of the nitrogen absorbing plant.
Future options include nitrogen stripping beds (wetlands, stock pads, sawdust, and greenhouse plant waste) and biodigesters.
