Other claims from this paper (5)
- Method / resource The fertilizer response model fit yield data very well.
- Method / resource Equally good fits could arise from very different parameter values.
- Method / resource Chemically estimated soil nutrient supply parameters substantially agreed with yield-fit averages.
- Method / resource Chemical estimates of B N , B P, B K and a N were consistent with model fitting.
- Observation Authors conclude the theory broadly accords with field results despite limitations.
