Backed by 8 years of research and development,
Renew biological fertilizer is a highly effective
nutrient source.

The complex organic matter present in Renew are highly beneficial for long-term soil structure, nutrient and water holding capacity, providing plants with an ideal growing environment. Use of Renew Biological fertiliser helps to maintain a healthy soil ecology that can fix Nitrogen from the air and work with plants to provide nutrients in available forms. Such systems have a higher Organic Matter than a conventional system, resulting in an increase in Carbon stored in the soil.

An extensive regime of field testing provides ongoing performance information about Renew Biological Fertiliser in a range of situations, comparing soil nutrient levels, a range of other soil parameters and plant yield in Renew and synthetically fertilised areas.


Cumulative research data

Scientific Production of Renew

Renew biological fertilizers are produced according to the Luebke system. The Luebke system involves vigorous daily and weekly testing of windrows to ensure a high quality end product, which is high in organic matter, humus, beneficial microorganisms and macro and micronutrients. The Renew team can adjust the nutrient content of Renew biological fertilizers to meet individual requirements.

Renew Biological Fertilizer in Vines between October 2009 and April 2011

Whole of block experiment at Meadowbank vineyard, Cambridge.
Renew biological fertilizer was applied to the soil surface in a 20cm wide strip underneath the dripper line.
Application of Renew biological fertilizer lead to:
• Increased soil infiltration rates
• Improved soil water holding capacity
• Increased biological activity
• Increased soil depth
• Decreased soil bulk density
• Improved soil structure
• Improved nutrition
• Increased yield while maintaining quality Renew biological fertilizer did not increase costs.

Aerobic Biological Extract for Suppression of Walnut Blight in 2008/09

Small randomised complete block experiment at Rosevale, Northern Tasmania.
Aerobic biological extract and the standard chemical bactericide were applied eight times during the season, generally one day prior to rainfall and until runoff using a hand sprayer.
Application of aerobic biological extract lead to a 70% reduction in walnut blight at harvest.
Aerobic biological extract also provided:
• Soluble nutrients
• Beneficial microorganisms

Renew Biological Fertilizer in Hops between Summer 2010 & 2011

Demonstration trial at Hops Products Australia, Bushy Park.
In 2009, the soil was deep ripped in both directions with a YeomansTM soil renovator and cross ploughed with a tyned ripper one month before application of 50m3 of Renew and was then power harrowed after Renew application. The hops are Southern Hallertau and were planted as sets taken from cuttings one month after application of Renew. In 2010, 10m3 of Renew was applied to the soil surface. Application of Renew biological fertilizer led to:
• Increased soil infiltration rates
• Improved soil water holding capacity
• Increased soil biological activity
• Increased soil depth
• A greater percentage of soil organic matter and carbon
• Improved soil structure
• Improved nutrition
Use of Renew lead to a healthier soil and a greater soil volume for young hop roots.

Renew Biological Fertilizer in Dairy Pasture between Spring 2010 and Autumn 2011

Small randomised complete block experiment in the Derwent Valley.
Renew biological fertilizer was applied to the soil surface at various rates on established pasture.
Application of Renew biological fertilizer led to:
• Significantly greater infiltration rates
• Increased biological activity
• Increased soil depth
There was no significant difference between treatments for total production or increases in pasture height and no significant difference between treatments for percentage pasture consumption by dairy cows or percentage decrease in pasture height pre and post-consumption.
Renew biological fertilizer has the potential to improve soil health in dairy pasture and maintain pasture yield and height for dairy cow consumption.

Renew Biological Fertilizer in Pine Trees between June 2010 and June 2011

Whole of block experiment at Norske Skog, Bushy Park.
Renew biological fertilizer was applied to the soil surface at various rates.
• Pine trees treated with Renew biological fertilizer at 20m3/Ha grew significantly taller
• Pine trees treated with Renew biological fertilizer at 20m3/Ha or 200kg/Ha of DAP had significantly greater diameters than pine trees treated with 3.5m3/Ha of Renew or untreated trees.

Renew Biological Fertilizer with Trichoderma for onion white rot control

Small randomised complete block experiment at Wesley Vale, North-West Tasmania.
Application of Renew biological fertilizer with Trichoderma lead to a 70% reduction in onion white rot.
Renew biological fertilizer with Trichoderma also supplies:
• Macro and micronutrients
• Soil organic matter and carbon
• Water infiltration and moisture
• Improved soil structure and potential rooting depth
