Feeding the world’s growing population

New Zealand’s reputation as a quality food producer is growing.

Optimising food production

Over the next 50 years farmers around the world will need to produce more food than has been grown over the past 10,000 years.

Best use from a limited resource

Fertiliser helps farmers produce food efficiently by replenishing the soil. But fertiliser needs to be used responsibly.

Responsible and sustainable nutrient management

The Fertiliser Association invests in research and tools to ensure farm profitability while minimising nutrient losses to the environment.

The Fertiliser Association of New Zealand promotes and encourages responsible and scientifically-based nutrient management.

Effect of breeding for lowered cadmium concentrations in chicory (Cichorium intybus L.) on foliar micronutrient concentrations

Chicory (Cichorium intybus L.) is being used increasingly as a summer livestock feed option. It has been shown to take up soil cadmium (Cd) into the leaf, and there is heritable variation in leaf Cd concentrations. The plant growth rate and Cd concentration are not linked which means it is possible to breed for vigorous chicory growth with reduced foliar Cd. There is no information available on the effects of selection of chicory for leaf Cd on the concentrations of micronutrients that are important for plant or animal health. This report examines the concentrations of essential trace elements: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), cobalt (Co), selenium (Se) and iodine (I), measured in chicory plants previously selected for either high or low foliar Cd, and progeny lines from crossings within the high and low Cd populations.

The study was jointly commissioned by the Fertiliser Association of New Zealand and the Ministry of Primary Industries.

Two PhD students who have been supported by the Association, have published information on their research. The first measures the impact of phosphate fertiliser derived fluorine on soil microbiology and white clover. The second analyses the effect of soil cadmium on root organic acid secretion by forage crops.
