Yellow leaves are not technically dead but are damaged or dying. Brown, crunchy leaves are generally what we consider to be dead, but as far as the contributions yellow leaves make to the overall plant, we can group them together with dead leaves.

Why are my plants' leaves yellow?
Roots area a vital part of the plant as they anchor the plant in the ground and collect nutrients for it. If the roots are damaged, the plant will not absorb the correct amount of water and nutrients. On a similar note, if plants outgrow their container, they can have compacted roots. Both of these scenarios are bad for your plant and should be looked into as a possible reason for yellow leaves.

Why are corn fields low in potassium?
Corn fields low in potassium may suffer more during frost, disease, and drought. Potassium is vital to many plant functions especially related to plant defense and water regulation. Potassium deficiency exhibits at first as yellowing of the leaf tips on lower leaves as it is mobile in the crop. Yellowing will progress down the margins eventually turning brown and resulting in leaf "firing." During drought, potassium uptake can be reduced as potassium moves to the plant roots through diffusion and water flow during water uptake by the plant. Therefore, even fields with adequate K can exhibit deficiency during prolonged dry weather. Sidewall compaction, which occurs when crops and planted into wet soil, can also reduce root growth and cause potassium deficiency early in the growing season, even when soil levels of potassium are optimal. For more information, read " Pennsylvania Nutrient Management Program ".
