RAVENSTONE GLENGARRY

“Ravenstone Glengarry” is a mixed cropping and grazing property. The site selected is a pasture phase sown with a mix of lucerne and arrowleaf clover.

 

Baseline soil analysis and compost treatments commenced in Autumn 2016. Fertiliser and lime was applied following standard practices used on this farm. Fertiliser is applied to this site when in cropping phase. However, no fertilizer has been applied in the past three years now it is in pasture phase.

 

Visual differences were beginning to emerge in February 2017. The most important observation to be made for this site is the slow pasture response compared to similar ASM compost treatments used on pastures in the Bungendore region. Rainfall is higher around Bungendore and the case studies have different pasture composition. “Glengarry” also has much lower levels of organic matter.

QUICK FACTS:

Property Size: 3,000 hectares

Type: Cropping & Livestock

Location: Ganmain, NSW

Aim: Improve wheat production

The site has a hard-setting shallow topsoil with high clay content down to one metre. Soil test results showed notable improvements in organic matter and nutrient availability in the top 10cm. There is still a long way to go for organic matter and soil chemistry to improve soil structure and increase water infiltration. A second application is recommended as nitrogen, phosphorous and sulphur levels are quite low. There are ongoing deficiencies in calcium, zinc, copper and boron.

 

This Case Study was jointly funded by ASM and the NSW Environment Protection Authority (EPA). NSW EPA provided financial support under their Organics Market Development Program to demonstrate the use of recycled organics (compost) on farms in NSW.
