CORN

[opabinia51]

There are actually a plethora of differnet varieties of corn out there that people don't normally think of: This year I am growing an eating corn called Golden Bantam Corn (an heirloom variety), another variety that I am going to make flour from but you can also eat called Indian Blue Corn (another Heirloom), Andian Blue Corn (destined to be flour and yes, it is also an Heirloom) and finally, Pink Pomegranate Popcorn.
You guessed what I will be using the last one for. You can also eat the last variety when it is young.

Anyway, Corn is a heavy feeder and needs to be grown in soil that is highly enriched with nutrients. It is very important to add lots of compost, manure and such to the soil before planting the corn. I personally have really sandy soil in my garden and have layed down a layer of manure followed by coffee grindings and coffee bean chaff. After that, I put another layer of manure, followed by a layer of excellant soil that we made last year. (Actually, the worms made it)

Anyway, if it only the plan were that simple. Manures don't just include animal excrement. On March 1 I will be planting white clover over my entire garden but, extra densely in the corn area. After mowing it a few times, the clover will be turned into the soil. Finally, along with the corn there will be peas, beans, melons, cucumbers and potatoes planted in the same area. These are all companion plants of CORN .
Also, I plant on planting some corn in the area where I will be growing my squash as corn is a companion plant to squash. And a note on different manures. Corn does not grow well in Chicken manure. And I have chicken manure in the squash area of my garden. Therefore, I do not expect to get any fruit from the corn up there.

Now, you know everything I know about corn.

As always, you go above and beyond in soil prep Opa. I'm sure your garden will reflect it in the long run. Good soil keeps plants healthy without the need for chemigation, a win for you and a win for the environment...

Here's another soil additive to ponder on. A lot of the organic folks in this neck of the woods are starting to rave about stone dust (not the construction material of the same name, but dust from stone cutting) as a soil additive. Higher yields, sturdier plants, better drought and cold tolerance; any number of benefits are being attributed (the going application is 14 lb.s per 100 sq. ft., but rates three times that show good results ands no adverse effects). I'd love to hear your take on it as a biologist, Opa, and certainly from anyone with first hand experience...

Well, given the cold tolerance I would start thinking of various elements in the rock but, to start going there I would have to know what rock the dust came from. ie) Is the stone a granite? Is it Marble? Once I knew that, I would know what elements are being added to the soil. I'll have to do some research to see what "Stone Dust" does for the soil.

[The Helpful Gardener]

The "study" I was made aware of was done in Massachussets with dust from a monument cutter; they said mostly granite, but who knows?

If granite then lots of potassium, right? That would make some sense...

[opabinia51]

Well, I saw somewhere on the Interenet or rather IN THE INTERNET that rock dust does supply potassium. I'd have to check on the Granite thing though... it's been a few years since I've taken any Earth and Ocean Science courses. Though, it would make sense with the potassium thing.

[opabinia51]

Granite dust has an NPK value of: 0/0/3.5-5.5

KNEW you would have an answer...

[opabinia51]

Found it in a book on composting that I was reading at the Horticultural Center of the Pacific library last weekend.

BACK TO CORN:


Planting corn: When planting corn the seeds should be planted between 1/2 inch to no more than 4 inches deep. This said, the deeper the better, 3 inches being the optimum depth.
As the seed germinates the stem and root grow from what is called a mesocotyl. Once the mesocotyl reaches the sun, it stops growing the stem grows from it. Therefore, if you plant your seeds 1/2 inch deep the roots will only have 1/2 inch to grow from but, if you plant the seeds 3 inches deep, the roots will be able to grow from 3 inches of mesocotyl the the plant will be that much more stable and have that much more surface area to extract nutrients from the soil.
Interplanting with corn: When planting beans and peas with the corn be sure to plant the non corn seeds at least one inch away from the corn plant Also, plant the beans on the South side of the corn patch. Be sure to give the corn plants a few weeks head start before planting the beans.

I take it that planting is nearly underway (said the snow-bound tundra dweller)...

[opabinia51]

Well, indoor planting is well underway. Tomatoes and plants that attract beneficial insects are all seeded indoors or in cold frames. The first of my corn will be planted most likely in mid or late April with some Plastic sheeting over the soil to warm it up. Peas will be planted at the same time (provided it's not to wet).
But, I'm reading a great book called: The Book of Garden Secrets and the above information came from there.... as well as the plastic sheeting tip. The sheets warm the soil up such that you can plant your corn earlier.
Actually, is some studies down it was found that corn in soil of 65 degrees took 10-12 days to germinate and corn in soil of 95 degrees toook 2 days to germinate. Though to me, 95 seems a little hot.

[The Helpful Gardener]

yea at that temp what are you doing to your soil flora?

[opabinia51]

Actually the research said that the high temperature killed the weed seeds/seedlings and most of the pathogens but, did not harm the beneficial fauna. And as far as flora was concerned, I guess all they were interested in was the corn. Still, I think 95 is a little extreme. I'm thinking athat 70 to 80 will be enough for me. But, at least I know that if the soil is really hot that my corn will still germinate.

[The Helpful Gardener]

When using bottom heat in a propagation range the mean is that 75 to 80 degrees range, so I think your on the right track...

[opabinia51]

I've been reading about a bunch of other vegetable seeds like onions and cole crops and they seem to be able to germinate at temperatures as high as 95 as well. Though, the literature says that most of the seeds germinate best between 75 and 80. Some are actually best germinated as low as 65.

Extremes on both ends.
