Plants grown at 5 nitrate (N) levels ranging from 2–36 mmol L−1 for lettuce and 2–43 mmol L−1 for zucchini squash and potato were harvested over the growth period to maturity at a minimum of 2 week intervals. Gamma × cubic response surface m

In New South Wales (NSW) Australia, the recent introduction of legislation to control runoff and charge for water used in agricultural production has encouraged commercial plant nurseries to collect and recycle their irrigation drainage. Runoff from

A market survey of Australian leafy vegetables and a winter and spring experiment with Swiss chard were conducted to examine nitrate and nitrite levels in leaves. The relationship between growth response to nitrogen (N) supply and light level and acc

The relationships between leaf nutrient content, leaf age, and within-canopy light exposure were studied in 10–11-year-old Macadamia integrifolia cvv. 660, 781, and 344 at Alstonville (28˚59′S, 149˚E), New South Wales, during autumn and spring

Sustainable fertiliser management involves maximising production, preventing on-site soil degradation and minimising off-site movement of nutrients. In the past, fertiliser management has been driven by the need to maximise production. Fertiliser cos
