Alfalfa Over Hardpan
I have land graded for alfalfa and some of the checks are low and water
will stand on the low checks in the winter. There is on an average from
two to three feet of soil on top of hardpan and hardpan is about two
feet thick. Will water drain off the low checks if the hardpan is
dynamited, and will this land grow alfalfa with profit?
Yes; much of the hardpan in your district is thin enough and underlaid
by permeable strata so that drainage is readily secured by breaking up
the hardpan. Standing water on dormant alfalfa is not injurious.
