Product Overview

Summary: This Nutrient Management Standard Operating Procedure provides a clear, evidence-based framework for planning, applying and monitoring nutrients across agricultural and horticultural operations. It helps Australian businesses optimise yield and quality while meeting environmental and regulatory expectations around fertiliser use and runoff management.

The Nutrient Management Standard Operating Procedure is designed for Australian primary producers and agribusinesses that need a structured, defensible approach to fertiliser and soil amendment use. Nutrients are a major input cost and a key driver of yield, quality and product consistency, but poor management can lead to runoff, leaching, regulatory scrutiny and reputational damage. This SOP sets out a practical, step‑by‑step method for assessing soil and plant needs, selecting appropriate nutrient products, timing applications, and recording all activities in line with best practice and audit requirements.

Developed with Australian conditions in mind, the procedure supports compliance with environmental expectations, assurance programs and customer specifications, while also integrating with broader farm management plans. It provides clear guidance on interpreting soil and tissue tests, aligning nutrient inputs with crop growth stages, managing nutrients under irrigation, and minimising losses to waterways and groundwater. By standardising nutrient decisions across teams and seasons, this SOP reduces guesswork, supports staff training, and helps demonstrate due diligence to regulators, auditors and supply chain partners.

Key Benefits

• Optimise crop yield and quality by matching nutrient applications to soil status and plant demand.
• Reduce input costs by avoiding over‑application, duplication and poorly timed fertiliser use.
• Demonstrate environmental stewardship by minimising nutrient runoff, leaching and impacts on local waterways.
• Support compliance with Australian assurance schemes, customer standards and environmental regulations.
• Standardise decision‑making and recordkeeping so any staff member can follow a consistent, auditable process.
