BIOGRO - Who are we?

BioGro has been at the forefront of the organics movement for over 30 years. It all started when a group of organic pioneers came together with a common vision. This vision was to create an accredited and recognised certification body that assisted New Zealand producers looking to turn organic. BioGro's mission is to enable a sustainable and ethical future for producers and consumers.

The BioGro logo is the most recognised organic logo in New Zealand. BioGro certified producers carry the BioGro logo on their products to assure their customers that the organic produce they buy is genuine.

The BioGro logo guarantees that a product is made without animal testing, genetic modification and the routine use of synthetic pesticides. It is the mark of a genuine organic product.

Why should you use compost?

  • Compost is an aerobic biological process that converts garden and food waste into a stable organic product suitable for transportation and ideal for paddock application.
  • Commercially produced compost can provide a valuable source of soil organic matter and slow release nutrients.
  • Applying good quality compost to agricultural crops has been shown to increase crop yields and soil "C" levels.

Fertility Benefits

  • Elevated soil nutrients (N, P, K) can be expected for more than 2 years after compost is applied.
  • A complete substitution of fertilizers with compost is not recommended. To get the best out of compost it needs to be applied with fertiliser N.
  • A crops ability to respond to available N (From soil, fertiliser and compost reserves) increases where compost has been applied.
  • Compost also provides other key nutrients such as Mg and Ca.
  • See Forago brassica and Arable case study boxes for information on profitable rates.

Soil & Environmental benefits

  • Soil organic matter and carbon content have been shown to increase significantly where compost was applied.
  • Soil Structure and water holding capacity tend to improve with higher application rates of compost. Lower rates of compost may require long-term application before the soil structure and water holding capacity benefits can be confirmed.
  • Due to much of the "N" content in compost being in a slow release organic form, the amount of nitrate leached tends to be lower than with standard fertiliser. This suggests there may be potential to reduce the total "N" leached where compost applications offset fertiliser applications.
