The beauty of diversity – and its agro-ecological benefit
As you look over the field, the first thing that catches your eyes is the varying heights of the wheat plants. There are giants standing out and dwarfs somewhat hidden in-between. Then you notice different colours, shades of green and yellow. You detect ears (the grain-bearing tip parts of the stem of a cereal plant) with awns (bristle-like appendages) and without, long ones and short ones – awns, that is to say, and also ears.
