During the growing season plants accumulate dry matter and nutrients.
Plant nutrients can accumulate in some parts of the plant and then be
translocated to other parts. A probability model is presented which de
scribes these trends. It is applied to corn (Zea mays L.) grown at Tal
lahassee, FL under irrigation with reclaimed municipal wastewater. Pla
nt samples were partitioned into leaves, stalks, and ears. Dry matter
and plant nutrients [nitrogen (N), phosphorus (P), and potassium (K)]
were measured for each component. Results showed that corn accumulates
dry matter in the order leaves, stalks, and then ears. Nutrients are
accumulated in the leaves and stalks and then translocated to the ears
. Model parameters were evaluated from field data.
