Abstract
The second law of thermodynamics states that entropy or randomness
in a given system will increase with time. This is shown
in science, where more and more biological processes have been
found to be independent. Contemporary work has delineated
the independence of yield potential (YP0) and nitrogen (N)
response in cereal crop production. Each year, residual N in the
soil following crop harvest is different. Yield levels change radically
from year to year, a product of an ever-changing and unpredictable/
random environment. The contribution of residual soil
N for next years’ growing crop randomly influences N response
or the response index (RI). Consistent with the second law of
thermodynamics, where it is understood that entropy increases
with time and is irreversible, biological systems are expected to
become increasingly random with time. Consequently, a range
of different biological parameters will influence YP0 and RI in
an unrelated manner. The unpredictable nature that environment
has on N demand, and the unpredictable nature that
environment has on final grain yield, dictate the need for independent
estimation of multiple random variables that will be
used in mid-season biological algorithms of the future.
