The raw inputs are derived from natural organic material, plus Ag Lime.  It is typically used in horticultural and agricultural applications to improve soil pH and structure, while adding organic matter. GroBalance combines organic matter with pH correction. It improves soil structure, boosts microbial activity, and neutralises acidity, making nutrients more available for crops. It is ideal for acidic soils needing both biological and chemical improvement. Bio Gro’s stable raw material input sources and quality control ensure the reliability of the typical nutrient profile, particle size and organic maturity.  #### **Simplified Typical Elemental Analysis** | ##### **Nutrient and Composition Analysis** | | | --- | --- | | Total Nitrogen | 1.0 – 1.2% | | Total Phosphorus | 0.4 – 0.6% | | Total Potassium | 0.6 – 0.8% | | Total Sulphur | 0.1 – 0.3% | | Total Calcium | 18 – 22% | | Total Magnesium | 0.7 – 0.9% | | Trace Elements (Fe, Zn, Mn, Cu, B, Mo) | Fe 0.8%, Zn 0.0150%, Mn 0.025%, Cu 0.041%, B 0.003%, Mo 0.00009% | | Organic Carbon / Organic Matter % | 16.27-18.60/28-32 | | ##### **Physical and Chemical Properties** | | | --- | --- | | Product Form | 70:30 Compost: Ag Lime | | Moisture Content % | 31 | | pH | 8.51 | | Electrical Conductivity (EC) | 3.31 | | Bulk Density | | | Particle Size Range | |   [Orders and Enquiries](https://content.biogro.com.au/agriculture-contact?hsLang=en-au) ![NIASA](https://content.biogro.com.au/hubfs/NIASA.svg "NIASA") ![EcoHort](https://content.biogro.com.au/hubfs/EcoHort.svg "EcoHort") ![BioSecure](https://content.biogro.com.au/hubfs/BioSecure.svg "BioSecure") ![Familyownedaustralianbusiness](https://content.biogro.com.au/hubfs/Familyownedaustralianbusiness.svg "Familyownedaustralianbusiness") ![NASSA\_](https://content.biogro.com.au/hubfs/NASSA_.svg "NASSA_") #### Newsletter Sign up to receive updates on new product announcements, industry news and more. ##### Follow Us ##### Mt Gambier - Head Office --- 2 Pinaceae Ct, Mount Gambier, South Australia, 5290 Phone: [(08) 8724 5555](tel:08-8724-5555) ##### Dandenong Facility --- 80-82 Ordish Rd, Dandenong South, Victoria, 3175 Phone: [(03) 8788 1700](tel:+61387881700) ##### Wandilo Facility --- 970 Wandilo Rd, Wandilo, South Australia, 5291 Phone: [(08) 8739 9257](tel:+61887399257) ##### Newbridge Facility --- 1477 Yorkshire Road, Newbridge, Victoria, 3551 Phone: [(03) 5437 3487](tel:+6154373487)  Copyright © 2026.
