Too much fertilizer? An observational association between inputs at planting and crop yield on a Saskatchewan farming operation

Recommended rates for fertilizer application with regard to crop utilization and soil management are discretionary and vary between producer and agronomist. This observational case study with Bayesian inference examines the association between application rates of inorganic nitrogen, phosphorus, potassium chloride and...
