Something else that may of help. There are crop growth models in
existence (eg, Soygrow and Pnutgrow) which predict how much a crop is
going to grow, given temperature, water and light conditions. The models
are used to support decision making systems. For example, the model can
predict how much a weed from a given species growing at a certain distance
from the plant will affect its growth and yield. That way, the farmer can
decide if the cost of weed control will be greater or lower than the cost
of the predicted yield loss.
I am assuming that all the information you are asking about had to go into
