Precision placement of fertilisers and seeds, in combination with no tillage, creates a major problem for sampling surface soils for analysis/data interpretation. Perhaps this will drive greater use of foliar analysis as a monitoring tool.

The Soil Test Crop Response (STCR) approach in precision agriculture utilizes soil testing and crop response trials to tailor nutrient applications specific to field and crop needs. By analyzing soil properties and crop performance data, farmers can optimize nutrient dosages using Variable Rate Technology (VRT) tools. This targeted approach prevents over-fertilization, minimizes costs, and reduces environmental impact by preventing nutrient runoff. STCR maximizes crop yields, promotes sustainable farming practices, and facilitates data-driven decision-making, representing a significant advancement in modern agricultural techniques.
