Yield Loss Calculator FAQ
What causes yield loss?
Yield loss can result from drought, nutrient deficiency, disease pressure, insect damage, compaction, or late planting.
How much yield loss is significant?
Even a 5–10% yield reduction can significantly impact profitability depending on grain prices and input costs.
Understanding Yield Loss in Crop Production
Yield loss refers to the difference between expected yield and actual harvested yield. Calculating yield loss in bushels per acre helps identify agronomic challenges, evaluate management decisions, and measure financial impact. Monitoring yield loss over time can reveal patterns related to weather stress, soil fertility, pest pressure, or equipment performance.
For example, if a corn field was expected to produce 200 bushels per acre but harvested 180 bushels per acre, the yield loss equals 20 bushels per acre, or 10%. Understanding this difference allows growers to determine whether the reduction was caused by environmental factors or management limitations.
Evaluating yield loss is especially important when comparing hybrids, fertilizer programs, irrigation strategies, or planting dates. Combined with yield per acre and harvest loss calculations, this tool provides a complete view of crop performance and long-term profitability.
