So do I need a soil test to determine how much organic matter the soil contains?

Soil organic matter has never been a consideration for me. I, and thousands of others, apply all grain type organic fertilizers at a rate of 15-20 pounds per 1,000 square feet regardless of what the OM is. Generally apply on Memorial Day, Labor Day, and some time around Thanksgiving. You can apply organic at the same time as chemical fertilizer if you feel the need to. There is no possibility of overdosing by applying both at the same time.

Of the two products listed above, is one better than the other?

Which one would you recommend?

Thanks

Second one because it is 10 cents per pound less expensive.

You can do as many do and simply guess at what you are doing or you can look at the soil and let it tell you what it needs. These simple soil tests may be of some use.

1.Testing for organic
matter. Put about 1 cup soil (enough to fill the jar to 4 inches) in
a clear 1-quart jar, with a tight fitting lid. Fill that jar with water and
replace the lid, tightly. Shake the jar vigorously and then let it stand for 24
hours. Your soil will settle out according to soil particle size and weight.
For example, a good loam will have about 1-3/4 inch (about 45%) of sand on the
bottom. about 1 1) Soil test for organic material. From that soil sample put
enough of the rest to make a 4 inch level
inch (about 25%) of silt next, about 1 inch (25%) of clay above that, and about
1/4 inch (about 5%) of organic matter on the top.

2) Drainage. Dig a hole 1-foot square and 1 foot deep and fill that
with water. After that water drains away refill the hole with more water and
time how long it takes that to drain away. Anything less than 2 hours and your
soil drains’ too quickly and needs more organic matter to slow that drainage
down. Anything over 6 hours and the soil drains too slowly and needs lots of
organic matter to speed it up.

3) Tilth. Take a handful
of your slightly damp soil and squeeze it tightly. When the pressure is
released the soil should hold together in that clump, but when poked with a
finger that clump should fall apart.

4) Smell. What does your
soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant
odor? The more organic matter in your soil the more active the soil bacteria
will be and the nicer your soil will smell, to a point. Too much organic matter
can be bad as well.

5) Life. How many
earthworms per shovel full were there? 5 or more indicates a pretty healthy soil. Fewer than 5,
according to the Natural Resources Conservation Service, indicates a soil that
is not healthy.
