What does your soil test say? Lets compare!
Comments (7)Availanble Nitrogen in soil is dependant on how active the Soil Food Web is and that is dependant on the soil temperature. So a low test for N now is not a big concern. Keep in mind that balance is the key, as long as things are in balance there should be few problems. It is when there is an excess of something, which can cause a problem with uptake or useage of something else where the problem lies. pH is good (6.2 to 7.0 is very good) Humus level (residual organic matter) is good (between 5 and 8 percent is optimal). The studies I have seen indicate the lead in your soil will probably not be taken up by the plants, but may cloing to the outside of root crops (carrots, beets, turnips, parsnips, potatoes, etc.) so those should be scrubbed good before eating....See MoreHelp me interpret my soil test
Comments (1)Organic matter is the lightest component of soil and it floats on the top of the water. Can't really tell from the picture what that is, but if it looks like organic matter then it probably is....See Moresoil test questions (OM, N/P/K) from my Extension report
Comments (2)Optimum levels of organic matter in solils is btween 5 and 8 percent, so while not quite there you are getting close. Soil pH, for most plants, is in the 6.2 to 7.0 range, so while a bit low yours is okay. Nutrients you want in balance, not too much of one and too little of another which is where the problem lies. Nutrient imbalances create more problems then they solve. Nitrogen is dependant on soil warmth, bacterial activity. When soils are cool and there is little bacterial activity there is not much N available, but as soils warm, and the bacteria become more active more N is available to the plants. Nitrogen sources with readily available N, soluble types, can make it look like there is ample N in the soil but that will also wash out of the soil quickly with excess water and is the source of nitrate pollution of ground water....See MoreI Got My Soil Test Results Back. What Do the Numbers Mean?
Comments (12)"just me 6" ... I agree with Kimmsr that you want to get the lime in there to start working, BUT I don't know that I think doing so before the builder levels things out makes sense. I just picture you distributing the lime well across the top of the soil, and the bulldozer coming and scraping the top 3 inches away here and filling in a dip there ... resulting in a really uneven distribution of the lime. If I were you I'd wait. If I read you right, we're just talking about waiting until Tuesday or Wednesday; I think waiting a few days is worthwhile to increase the chances you get your lime distributed pretty evenly. As to improving your "nasty sticky clay soil" ... lime will fix the pH, but I don't think it will affect the texture. You want better "tilth" ... not sure if a search on that word here will bring up articles that will help. Adding lots of organic material is the single best way to improve your tilth, for a variety of reasons. First, just mechanically, having lots of bits of organic stuff in between the sticky bits separates them and lets air and water in. Next, the soil beasties that are going to eat that organic stuff will, in the process, glue some of the clay particles together into aggregates (bigger bits), which tend to permit air and water to penetrate around/between them. Do you have a source of free municipal mulch? By that, I mean ground up leaves that a nearby city collected in the fall, let sit over the winter, and puts out for you to take the following year? That can be good stuff or it can be garbage-y. I have a couple of cities around me to choose from, and have a clear preference for one over another.... Alternately, if you're willing and able to spend, get a truckload of compost from a local nursery. Go there first to see what they'll sell you. My nursery sells it for $35/yard, and they're selling pretty nice stuff (ground a lot finer than the municipal free stuff, looks more decomposed, maybe is in a more managed pile over the winter?). Till it in to your soil after the builder and before you first plant. Then add more to the perennial beds. And keep adding more to any plants that can be mulched (nearly everything except grass) forever more. (Wood and bark mulches last longer, but ground up leaves feed the soil better.) By the way, don't let anyone sell you topsoil. You have plenty of the mineral component of soil already. You want more of the organic component, and that's the only part it makes any sense to pay anyone to haul to you. Don't let them talk you into a mix of compost and topsoil either ... that would be better for their profit, but not better for you. (UNLESS you have a shallow area you want to fill ... but then, the builder should fix that, right?) I know, I'm not giving a lot of advice on the soil test. But you asked how to make sticky clay better, and in my flower beds, compost and leaf mulch are what does it. - LCPW p.s. On the "posey power" ... hard to say without knowing what it is, and some facts about what KIND of clay you have. I have learned here that one kind of clay actually can be broken up well by a chemical additive that nurseries sell. But many many folks have asked about it and knowledgeable folks here have said, "you're in a part of the country with clay that won't be helped by that in the least". I'd say don't do it until you know more....See Moregardengal48 (PNW Z8/9)
