I have two raised beds that I'm asking about here.  For both beds, I had the soil tested in Nov 2023, May 2024, and again now.  I don't understand why my soil is doing what it's doing.  All testing was done at the same place, University of Vermont Extension .

Bed 1 Nov 2023 results: Phosphorus - 16.5; Potassium - 110; Magnesium - 234
          May 2024 results: Phosphorus - 15.0; Potassium - 78; Magnesium - 188
          Nov 2024 results: Phosphorus - 29.8; Potassium - 157; Magnesium - 220
         
          In addition, calcium went from 2060 to 1949 to 2821 and Sulfur went from 3.0 to 4.0 to 443

Bed 2 Nov 2023 results: Phosphorus - 6.0; Potassium - 102; Magnesium - 160
          May 2024 results: Phosphorus - 17.1; Potassium - 94; Magnesium - 223
          Nov 2024 results: Phosphorus - 33.2; Potassium - 170; Magnesium - 302
         
         In addition, calcium went from 1453 to 1949 to 2580 and Sulfur went from 4.0 to 3.0 to 123.0

I don't understand what's going on here, or what to do about it.  Adding nutrients is straight forward, but removing them?  some of these are off the charts.

What a puzzle you have on your hands, could you run me through what amendments/ingredients you use in your raised beds and how often you have added to them?

I mixed up the beds in one set of results.  I'm enclosing the soil test results for these two beds and some new ones I'm putting in.

I had both knees replaced over the winter, so I wasn't able to do much before.  I could do more in the spring, but not a lot.  Now I can do the work and I'm anxious to get the beds going.

The Nov 2023 set was taken after the first season I tried to grow in them with mixed results.   It was my first time growing in them since purchasing the property.  I don't know how it was cared for before.  At this point I added some lime.  I added more lime this past May, along with gypsum and some 10-10-10 fertilizer.  I was able to grow more veggies this summer.  Corn, and greens grew well, squash, cukes and onion grew ok, tomatoes not so well.  

The combined soil tests for the new beds actually totals 400 S/F of area, not 200.

I haven't done anything this fall yet, other than to till for the new beds.  I enclosed test results for them as well.  As you can see, the unammended soil pH on my property is very low.  I was going to try to amend and plant next spring and build raised beds in the fall, but I'm rethinking that now.  Would it make sense to remove the soil from raised beds left and right, replace it with purchased soil, spread the removed soil over the new beds, till it in, then add compost, composted manure and mulch before planting in the spring?  I'm thinking this would even out the nutrients in the new beds, while letting me start over with the current raised beds.

I was going to try to take a couple of years to try to fix this, but after the election I really feel the need to be able to grow enough food to meet my family's needs ASAP.  I didn't want to have to purchase soil and compost for the new beds, but I can if it makes sense.  Replacing the soil in the raised beds and using it to partially fill the new beds may make sense.

Hi Diane, I am not soil expert but I have some books on soil science and try to interpret your results based on those. The first two test results look good and there'snothingto worry about. In the last report, you probably mixed in some peat based mix that shows a very high OM, low nutrient level and low pH. That doesn't reflect the real condition of your soil.

In the frist two reports, pH 6.2 is in a good range, you don't have to get it exactly to 6.8. It's very difficult to change pH over a large amount of soil. Ca/Mg/K ratio is also normal. Soil organic matter level is also in a good range. If no peat or coco coir was added and those 5% OM is mainly from decaying plant residues and microbes, this number means fertile soil but it can certainly go even higher.

I would mulch the beds with plant residues over the winter, keeping the erosion down. Then mix quality organic matters such as alfalfa meal or cotton seed meal in early spring a few weeks before planting. Nutrients will be slowly released through microbial activity, which feed the plants steadily over a long time, also in synchrony with the plant's growth. I don't trust store bought compost though. The texture is totally different from home made ones and I suspect there is sewage sludge added. Your soil profile seems quite good to me, just give it organic fertilizers to release its full potential.
