Soil Test Report. 12.8.15

Here is a summary of the soil test report from this week's test.  The area tested was the home orchard, and the report recommendations were based on that.  I had this done by simplysoiltesting.com in Burlington Washington.  Their reports seem very detailed and understandable.  The interpretation below is per their report.

Soil Test report
Phosphorus 227 ppm =  very high
Potassium 431 ppm = very high
Calcium 1405 ppm = high
Magnesium 222 ppm = high
Boron 0.7 ppm = medium
Sulfur 3.7 ppm = medium

Organic matter 8.8% = high

Soluble salts 0.14 mS/cm  low
 
Zinc 1.7 ppm = high
Manganese 4.0 ppm = very high (normal is 0.7 - 1.4)
Copper 0.7 ppm = high
Iron 46.5 ppm = very high (normal is 2.5 to 5.0)

pH 5.31 (3 years ago this was 5.05)

They don't test nitrogen, stating it is too transient.

They recommend lime 44 pounds per 1000 square feet - if mixing to 8 inches deep, or 11-14 pounds if scattered on soil surface, nitrogen 2.3 pounds per 1000 square feet, and small amounts of borax and sulfur supplements.  They give recommended amounts of organic supplements, which is what I requested, as either blood meal, Alaska fish fert (46 pounds per 1000 sq feet - could get expensive and stinky), organic urea, 5 pounds per 1000 sq feet.  It's up to me to determine the peecycle amount.

When tested 3 years ago, most was similar but  the pH is higher.  I did spread lime at that time.  That may explain the increase in pH and calcium since the last report.  I have not used any fertilizer other than peecycling.  I think back then they stated calcium was also low, and at that time also recommended some borax similar to this time.  I did not supplement borax.

Despite the low pH, most of the trees have done well.  Maybe they'll do better with further correction of the acidity.

Late December Gardening. Seedlings, Kitchen Garden Prep, Raised Beds, Lime. 12.28.13

Okra Seedlings

Seed and Cutting Setup

Today didn't do much.  In winter garden work can be when I feel like it.

Noted the okra seedlings have germinated.  That's 4 days.  See warming mat makes a big difference.  I had soaked them 1/2 day before planting.  That probably also helped.

I don't know how they will do inside.  That's why it's an experiment.

Chili pepper seeds have not germinated yet.

Opened fig cutting bags 2 days ago, and rinsed them.  Anticipate doing the same tomorrow.

Today -

1.  Spread lime in raised beds and around trees and shrubs.  I calculated the amount as 1 pound per 4 X 8 raised bed.  I estimated the area around the trees and shrubs, and orchard trees, and applied similar amount.  Two 25 pound bags.  Will need another later.

2.  There were some garlic plants and perennial onion volunteers that I pulled out a week or two ago when I cleaned up that raised bed.  I had set them aside.  Today I separated them into individual plants, and planted them.  They did not look the worse for wear despite sitting outside a week or 2.

3.  Spread blood meal around onion starts.  Something has been eating them.  Maybe the blood meal will be a deterrent.  The amount is the recommendation of nitrogen supplement.

4.  Cleaned up the strawberry raised bed.  Removed the fencing.  Raked out the deteriorating straw.  Pulled the few weeds.  Did not cut off dead leaves.  That can be later.  Plan:  Mulch this winter with compost.  Later this winter build a better fencing system, maybe a hinged box with chicken wire sides.  Wait until growth starts, to add straw again.

That's about it.  Sounds like a lot, but non of it was difficult and none took very much time.

Soil pH for various plants. 12.26.13

After having the soil tested, and reading the recommendations, I looked up what a number of my garden plants require.   According to the info I could find, many would tolerate soil pH in the range of my soil, pH 5.05.  Which must make sense, because they grew in it last year.  However, if I lime the soil, maybe some or most will be more vigorous, or more productive, or produce earlier.

From this site - the gardenhelper.com  I edited out vegetables I don't grow and don't plan to grow.

Not related to this topic, but thought about after looking for images to ponder for this post.  The vintageprintable image at the top does not give a source, but the caption states those are 3 year old black locust trees, form seed, in Kentucky.  About 1910.   That's a lot of growth in 3 years.  It makes me wonder - is it because they are from seeds?  Because they are a fast growing black locust?  Because the climate and soil in that Kentucky forest was super good in the 1900s?  All?  I think more people should try to grow trees from seeds.  We would have more diversity, the trees would be free, and if some achieve that size, that fast, then there would be faster biomass accumulation and faster shade.

Soil Analysis. 12.25.13

This report is very helpful. It changes significantly how I am going to supplement my garden and orchard soil this year.

I'm very impressed.  It is a well written, easy to follow report.  They were fast and thorough.  I am happy I sent them a sample and will make use of the recommendations.

The main points-

- My soil is very acidic.  They recommend lime.  That also increases the calcium.
- The iron level is super high.  I thought form the leaves iron was low.  I planned to supplement it.  Wrong thing to do.
- The recommendations include adding trace boron, trace copper.   For that, add a tiny amount of borax, and a tiny amount of copper sulfate.  The recommended amount is so small, I don't know if I will do anything about that.  Better to under-do it than over-do it.  Too much boric acid is toxic to plants.
- The recommendations include adding some epson salts for magnesium and sulfur.
- I thought the soil would need more potassium and phosphorus.  In reality, the potassium is high, and phosphorus is very high.  So just add a nitrogen source.  Fish emulsion might be a good source.
