The texture of the soil depends on the
relative amounts of different-sized particles that combine to make up the soil.
These particles can be as large as stone and gravel or as small as
clay. A typical clay soil is composed of approximately 60
percent actual clay, 20 percent silt, and 20 percent sand. The particles in a
sandy soil are so fine that it tends to be compact and interferes with the
oxygen supply for plant roots. Water has trouble entering this impervious soil,
and runoff is very common during rainfalls. A typical light
sandy soil is composed of approximately 70 percent sand, 20 percent silt, and 10
percent clay. The particles in a sandy soil are comparatively large, permitting
water to enter the soil and to pass through it so quickly that it often carries
nutrients with it and dries out very rapidly. The texture of sandy soils is
generally very difficult to modify because huge amounts of organic material must
be added. A typical loam soil is composed of approximately 40
percent sand, 40 percent silt, and 20 percent clay, making it an ideal garden
soil. It is easily worked and retains water and nutrients, which are slowly
absorbed by plant roots. A typical adobe soil is a clay soil
present in hot, dry areas of the country and is often very hard and cracked. It
has all the disadvantages of a heavy clay soil and, being much drier, is more
difficult to correct.

It is hard to predict how science is
going to turn out, and if it is really good science it is impossible to predict.
If the things to be found are actually new, they are by definition unknown in
advance. You cannot make choices in this matter. You either have science or you
don't, and if you have it you are obliged to accept the surprising and
disturbing pieces of information, along with the neat and promptly useful
bits. The only solid piece of scientific truth about which I
feel totally confident is that we are profoundly ignorant about nature. Indeed,
I regard this as the major discovery of the past hundred years of biology. It
is, in its Way, an illuminating piece of news. It would have amazed the
brightest minds of the 18th century Enlightenment to be told by any
of us how little we know and how bewildering seems the way ahead. It is this
sudden confrontation with the depth and scope of ignorance that represents
the most significant contribution of the 20th century science to the
human intellect. In earlier times, we either pretended to understand how things
worked or ignored the problem, or simply made up stories to fill the gaps. Now
that we have begun exploring in earnest, we are getting glimpses of how huge the
questions are, and how far from being answered. Because of this, we are
depressed. It is not so bad being ignorant if you are totally ignorant;
the hard thing is knowing in some detail the reality of ignorance, the
worst spots and here and there the not-so-bad spots, but no true light at the
end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to be some satisfaction.
There are probably no questions we can think up that can't beanswered, sooner or
later, including even the matter of consciousness. To be sure, there may well be
questions we can't think up, ever and therefore limits to the reach of human
intellect, but that is another matter. Within our limits, we should be
able to work our way through to all our answers, if we keep at it long enough,
and pay attention.
