This is my first post here; I hope I'm not overlooking something!
I recently received an soil report and wanted some input. I'll give some background before jumping right into it.
We bought this property 2.5 years ago. I've gradually been putting this veggie garden in, breaking up sod and removing rocks. At this point it's a fenced in garden about 10' x 45'. All I've been adding are leaves, wood chips, and a horse bedding/manure mixture. Overall it did well. Carrots, brussel sprouts and cabbage sulked, but that could have been due to shading by other crops and water shortage. The soil drains incredibly fast. It is a sandy loam, with frequent fist+ sized rocks. It gets full sun and we live in zone 4b. Long winter, with a decent snow cover. It's snowing this very minute, in fact. Upstate New York.
Two weeks ago I brought a couple soil samples to the local Cooperative Extension. I also brought a sample from the front yard where a cherry tree is growing very slowly. The front yard sample is another topic, I may start another post once I get those results.
The veggie garden results:
Soil ph is 5.8 (low)
Phosphorus 61 lbs/acre (very high)
Potassium 108 lbs/acres (medium)
Organic matter 6.6%
Recommend adding 3.5oz nitrogen for every 100 square feet
I was expecting the low nitrogen, but what would be the best way to raise it without further elevating the phophorus?
Should I just grow a ton of beans and then chop and drop them? I now know that horse manure is a source of phosphorus, so I'm going to discontinue that for sure this coming year. I'm not horribly concerned by the low ph, most of what I grow prefers a more acidic soil anyways. I certainly don't want it going any lower however.
Thanks all. Sorry if this is a rather basic question.
