Does corn grow better and sandy and silt soil and why ?

Question

I need for someone to help me with my crop science research

report . I grow corn for a 4 or 6 weeks straight. I want to see what the different and soil .

Answer 1

Yes , the corn will grow better there. Corn would generally grow better in the field in a silt, or silt loam, soil than in a sandy soil.

Silt has a better water holding capacity ability, to hold more plant nutrients etc, but trying to prove this in a laboratory is going to be difficult. Corn will grow perfectly well in pure sand if the moisture and nutrients are supplied.

Just taking a sandy soil and a silt soil and growing corn in them, you are not going to be able say any differences you might see are due to the soil.

You need an experiment with some control over the thing that you want to test. Have a talk with your instructor before trying the experiment that you are talking about, because I am afraid you will just be wasting your time as you have it planed. And more over t*t suits the overall gropwth.

Answer 2

Corn and most other crops will grow better in a silty clay loam, but if a sandy soil allows the corn to get its roots down quickly to water down deep, and the sandy soil is kept perfectly fertilized and has lots of humus, it can do  as well.

Humus has all of the benefits of a silty clay loam, unless the silty  clay loam also has that humus.

Proving that a silty clay loam is better than sandy loam would likely depend on using a field of each that has had an equal amount of rain, fertilizer etc. But a big part of the advantage of the silty clay loam is the inherently superior amount of nutrients in the clay. When we have the same amount of available nutrients instead of the same amount of applied nutrients, we still have the risk that the sand will allow the nutrients to leach out, should a significant rain occur.

Setting up a perfect test may require a lot of effort, and it would have to be repeated for ever so many years with different amounts of rainfall.

The ability of a silty clay soil to store plant nutrients from year to year, even to store water from year to year has to be weighed... we can be getting superior performance from residuals that we are not adding into the considerations.

But I have seen silty clay that forms a hard surface crust do much less than a sandy soil when both are getting short brisk rainfalls. The sandy soils absorbed so readily, and were able to  keep the crop growing, The silty clay saw a lot of runoff.

Just try putting all this into a simple experiment!

Sallie we call that 'bottom land" and yes it does. Why, well my folks have done it for 200 yrs and they have a great yeild, as well as growing a little Mary Jane
