Why Uneven Fertiliser Spreading Is Quietly Costing Farmers More Than Rising Input Prices
Rovic is a South African-based leader in agricultural mechanisation, specialising in the engineering, manufacturing, and distribution of high-quality farming equipment. With a strong focus on innovation, precision, and technical efficiency, the company delivers advanced solutions—from tillage and spraying to fertiliser application—designed to help farmers maximise productivity while reducing operational and environmental risk.
Across South Africa’s grain, pasture, and mixed-farming regions, fertiliser remains one of the most significant annual input costs on the farm. Lime, gypsum, granular fertilisers, manure, and compost are all applied with the same objective: to improve soil fertility and protect yield potential. Yet for many producers, the difference between a profitable season and an underperforming one often comes down to a single, overlooked factor — spreading accuracy.
While fertiliser prices receive most of the attention, the true hidden cost lies in uneven application. In an era of tight margins and increasing regulatory pressure, understanding how fertiliser is spread is just as important as what is spread.
The Financial Reality of “Even Application”
Uneven fertiliser spreading is more than a technical inconvenience — it is a direct financial leak. Over-application wastes costly inputs and increases the risk of nutrient runoff, soil imbalance, and environmental damage. Under-application, on the other hand, restricts crop growth and yield potential long before rainfall or temperature become limiting factors.
Every fertiliser recommendation is calculated to deliver a precise nutrient rate per hectare. When that rate varies across the spread width, or drifts during operation, the return on investment is immediately compromised. Patchy crop development, inconsistent nutrient uptake, and uneven yields are often the visible symptoms of a problem that began at spreading. In many cases, farmers unknowingly lose a substantial portion of their fertiliser investment simply because the spreader cannot deliver consistent rates across the full working width.
Why Conventional Spreaders Struggle
Traditional spreaders commonly face three core challenges:
Inconsistent material flow, caused by bridging, variable moisture content, or excessive hydraulic pressure. Uneven left-to-right distribution, particularly during boundary spreading or on sloping terrain. Rate drift, requiring frequent manual recalibration when changing products or application rates.
As fertiliser products vary widely in density and flow characteristics, operators are often forced to rely on estimates rather than real-time measurement. These inaccuracies may appear small, but over hundreds of hectares they accumulate rapidly — costing yield, fertiliser, and confidence.

Rovic Syncrospread: Engineering the Solution
The Rovic Syncrospread range was engineered specifically to address these inefficiencies through controlled material flow, precise metering, and real-time rate management.
At the heart of the system is a hydraulic twin-chain conveyor, allowing independent left- and right-side control of material flow. This enables accurate boundary spreading, headland shut-off, and compensation for uneven terrain — capabilities that are not possible with conventional single-chain systems.
A lined chain floor and hopper bridge reduce the hydraulic pressure required to move material, improving durability while ensuring a consistent feed to the spinners. This design also prevents material compaction on the bin floor, lowers power demand, and reduces long-term wear.
The Syncrospread’s open discharge design, adjustable stainless-steel rear door with height scale, and drop-point adjustment allow the machine to handle a wide range of products — from light, bulky manures to dense granular fertilisers — while maintaining a stable and predictable spread pattern.
Precision You Can Measure: Accu-Spread® and AFSA Compliance
Precision spreading is not a marketing claim — it is something that can be independently verified.
The Syncrospread has been tested and accredited under the Accu-Spread® certification programme, administered by the Australian Fertiliser Services Association (AFSA). During independent testing, the Syncrospread achieved a coefficient of variation (CV) below 15% at a 36-metre spread width when applying urea, meeting stringent international standards for evenness of application.
Accu-Spread® certification provides farmers and contractors with peace of mind that fertiliser is being applied evenly and accurately across the entire working width. It also serves as an important risk-management and compliance tool, especially in operations where nutrient stewardship and environmental accountability are becoming increasingly important.
FertCare Certification: Responsible Nutrient Management
In addition to Accu-Spread® accreditation, the Syncrospread is also FertCare certified. FertCare is an internationally recognised training and certification programme that promotes responsible nutrient application, environmental protection, and best management practices.
FertCare certification reinforces that the Syncrospread is designed not only for accuracy, but for responsible fertiliser use, helping farmers:
- Optimise nutrient efficiency
- Minimise over-application and runoff
- Protect soil health and surrounding ecosystems
- Meet evolving environmental and sustainability standards
Together, FertCare and Accu-Spread® certification position the Syncrospread as a precision tool aligned with modern nutrient stewardship principles.
Smarter Control, Less Guesswork
Modern fertiliser application demands more than mechanical reliability — it requires data-driven control.
The Syncrospread is ISOBUS-ready, compatible with leading control platforms including Topcon, GreenStar, and Raven. Optional dynamic weighing systems with load cells allow the machine to calibrate continuously while spreading, eliminating the need for repeated manual recalibration when changing products or rates.
Encoders, RPM sensors, and optional pressure sensors continuously monitor chain speed, spinner speed, and hydraulic load, ensuring accurate metering even as field conditions change.
Built for Longevity and Return on Investment
Precision only delivers value if it lasts.
All spreading components in direct contact with fertiliser are manufactured from stainless steel, significantly improving corrosion resistance and service life. A patented rock separator, with adjustable fin spacing, removes stones before they reach the spinners, protecting bearings and reducing downtime.
Heavy-duty axles, flotation tyres, a rubber-block sprung drawbar, and optional self-steering tandem axles ensure stability, reduced soil compaction, and consistent performance across uneven terrain.
The Takeaway
Fertiliser will always represent a major investment on the farm. Losing even a small percentage of that investment to uneven spreading is a cost farmers can no longer afford.
By combining mechanical durability with certified accuracy, intelligent control, and responsible nutrient management, the Rovic Syncrospread transforms fertiliser application from a variable cost into a controlled, measurable, and compliant investment.
Because in modern farming, precision isn’t optional — it’s profit.
