The innovative Croptune™ app offers a reliable, realtime nitrogen monitoring solution, helping growers of potato and other crops make precise fertilisation decisions that maximise efficiency and improve crop performance.
Potatoes require precise nitrogen levels, suited to each growth stage. While deficiency will lead to poor quality and reduced yields, excessive nitrogen leads to irregular vegetative growth that interferes with tuber development and increases susceptibility to disease.
Traditional nitrogen monitoring relies on laboratory analyses, which are costly and time consuming. Variability across the field further complicates fertilisation strategies, making it difficult to match nitrogen application to actual needs.

Real-time nitrogen analysis
Croptune™ eliminates the uncertainty in nitrogen management by providing instant, field-based nitrogen measurements using only a smartphone. The process is straightforward: Farmers capture an image of potato leaves, and Croptune’s advanced algorithms analyse chlorophyll levels which correlate with nitrogen content. The app then delivers a nitrogen status report, helping the farmer to determine whether fertilisation is necessary.
This real-time approach ensures that nitrogen is applied efficiently, reducing unnecessary fertiliser use and improving crop performance. Farmers no longer need to rely on delayed lab results or make fertilisation decisions based on estimates.
Optimised for potato farming
In South Africa, intensive farming often leads to soil nutrient depletion, requiring careful nitrogen management. Potatoes have specific nitrogen demands that change throughout their growing cycle. Early shortages can limit yield potential, while excessive nitrogen later in the season can harm tuber development.
With Croptune™, farmers can monitor nitrogen levels in real time and adjust fertilisation accordingly, ensuring consistent crop health.
Data-driven field management
For large-scale potato growers, Croptune™ provides an advanced dashboard with reporting tools to track nitrogen trends across different fields. Farmers and agribusinesses can compare nitrogen levels across plots, identify deficiencies, and adjust fertilisation plans with confidence.
The dashboard allows for improved resource allocation, ensuring that nitrogen is used efficiently without waste. By providing long-term data on fertiliser performance, Croptune™ supports better planning, sustainability, and profitability.
Seamless integration
Unlike traditional nitrogen testing, Croptune™ requires no specialised equipment or lab analysis. Farmers can get nitrogen readings instantly and directly from the field, using only their smartphones. This allows for real-time decision-making and more precise fertilisation schedules.
The system is designed for practicality, making it easy to integrate into daily farming activities. There is no need for additional hardware or expensive tools, making Croptune™ an ideal solution for both small- and large-scale farmers.
Why Croptune™?
Croptune™ is ISO 17025-certified, ensuring reliable and accurate nitrogen measurements. By applying nitrogen only when needed, farmers can reduce fertiliser and application costs, and improve efficiency. The app delivers instant results, eliminating the waiting period associated with lab testing. With real-time data, farmers can ensure their potato crops receive optimal nutrition, leading to healthier plants and higher yields.
For large-scale farming, Croptune’s dashboard provides a centralised platform for tracking nitrogen levels across multiple fields. This enables smarter, data-driven farm management, reducing waste while improving overall productivity.
Besides potatoes, Croptune™ is calibrated to monitor nitrogen levels in processing tomatoes, wheat, maize, various fruit trees, greenhouse vegetables, and more.
For South African farmers looking to improve nitrogen efficiency and crop performance, Croptune™ offers a science-backed, field-tested solution that is practical, easy to use, and highly effective.
