Thatís crabgrass and we donít want that growing in our field.
However, Iím not too worried because last Friday our farm crew

years ago farmers would have said that this field looked
"trashy," but now most farmers would say this trash or
residue looks great! You can see the rows or strips of soil that
arenít covered with as much residueĖthatís where we need to
dig to see how our seeds are doing. Letís dig some up.
can see our seeds have gotten bigger. Why? Well, to germinate the
seeds imbibe water, about 50 % of their weight in water to be more
precise. This causes the seeds to swell. The water activates the
