Kiwiphos

Direct application phosphate rock, New Zealand mined from the Clarendon deposit, Otago.

Overview

Direct Application Phosphate Rock (DAPR)

What is DAPR?

The Kiwiphos products are classified as DAPR (Direct Application Phosphate Rock). They are most suitable for maintaining long-term pasture production, typically blended with other required nutrients according to the needs of specific farms. Best suited to soils with pH levels of 5.8 or less, where the acid in the soil slowly dissolves the phosphate rock into plant-available form. During this process, soil acidity is consumed, offsetting the amount of lime required to maintain a given soil pH.

DAPR is a naturally occurring product, so some variation is to be expected. The figures below are derived from extensive testing by L&M, and any given product is reasonably expected to, but may not, fall within these parameters.

Application

How and where to use Kiwiphos

Application approaches

  • Heavier applications every 3 years or so
  • A heavy application followed by annual maintenance applications
  • Mixed with soluble phosphate

Best suited to

  • Maintaining long-term pasture production
  • Soils with pH 5.8 or less
  • Farms looking to reduce lime requirements over time
  • Operations seeking a 100% natural, locally sourced phosphate input
The long-term pasture yield achievable with Kiwiphos is likely to be at least 95% of that achieved with Reactive Phosphate Rock or superphosphate, assuming application of other required nutrients such as sulphur.
