It might make the soil better for the trees by allowing escape for surplus water through previous layers. It might allow the tree to root more deeply for moisture in those strata. It might allow water to rise from such strata if they have water under pressure. It might do other things good or bad, according to conditions prevailing under the hardpan.
In planting trees where hardpan is four feet from the surface is it necessary to blast the hardpan, or is there no benefit derived by the blasting? If there should be a good available soil under a shallow layer of hardpan, which you say is four feet from the surface, it might be of considerable advantage to bore into the hardpan and explode a dynamite cartridge in it.
It is a very vigorous grower and will yield a number of crops in succession although the water might be very near the surface, as in the case of the reclaimed islands in the Stockton and Sacramento regions and in shallow irrigated soils over bedrock in the foothills or over hardpan on the valley plains. In this statement, freedom from alkali is presumed. Vetches in San joaquin.
Both experience and actual determinations of moisture in this State show that cultivation to a depth of 5 inches conserves twice as much moisture in the lower soil as can be saved by a 3-inch depth of cultivation under similar soil conditions and water supply. It is all the better to go 7 inches if young trees have been treated that way from the beginning. Alfalfa Over Hardpan.
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. Trees Over High-Water. Which are the best fruit trees to plant on black adobe soil with water table between 3 and 4 feet from surface? The soil is very rich and productive.
Brown and Schaick have, or will have, the control for the whole line of the Salt Lick Pacific Extension, forty thousand dollars a mile over the prairie, with extra for hard-pan and it'll be pretty much all hardpan I can tell you; besides every alternate section of land on this line. There's millions in the job.

Sweet clover will grow anywhere, from a river sandbar to an uncovered upland hardpan, but it will not do much if your vacant spots are caused by alkali. More Than Dynamite Needed. I have some peculiar land. People here call it cement. It does not take irrigation water readily, and water will pass over it for a long time and not wet down more than an inch or so.
Two days sufficed for the owner and one man to clear and level the ground, dig post holes, set posts, and square the foundation. The soil was light sand with a clay hardpan three feet down. "Twenty-seven days each were put in by two men from start to finish, with assistance rendered by the owner. There were seven days by the mason, eight by carpenters, and four teen and one half by other labor.
But if your good soil is really only four feet deep and hardpan continuous below, the blast might cause fissures which would prevent standing water in the upper stratum. If you are sure of four feet of good soil above the hardpan you will have no difficulty in growing good trees, if you get the moisture just right and the hardpan slopes in such a way that surplus moisture will move away.
