Technical Abstract: Improvements in seedling emergence models may arise by accounting for variable and depth-specific accumulation of hydrothermal time in seed-bearing zones of soil, as well as tolerances of seed germination and seedling emergence in burial depth and, lastly, distribution of seed densities in soil, which is determined by tillage system. We have accounted for all of these variables in a model for common lambquarters (Chenopodium album L.). The new model appears to have greater universal application than previous models.
