Allophanic soil (1st of 2)

Allophanic soil

Crumbly and free-draining, these volcanic soils in the southern Waikato basin are some of the most productive in New Zealand. However, their allophane content, which holds phosphate in a form only slowly available to plants, means that relatively large amounts of phosphate fertiliser are needed for high dairy or crop production.
