How to amend soil based on soil test results
Comments (1)I know next to nutthin 'bout reading soil tests but a couple of advisories. Depending on who did the testing, some labs give recommendations for lime for agricultural purposes where they expect the lime to be mixed into the soil rather than spread on top. Keep in mind that grass does best in soil that is at a PH of 6.5ish or so.and that it is much easier to increase PH than it is to reduce it. So if you add to much lime... Second thing to keep in mind is that you do not want to add more than one pound of N per month at a time to an existing lawn. Also too much N in a seed bed is not beneficial to seedlings and can kill germenating seeds Thirdly, N and P leach pretty quickly, so adding more than the plant can use before they leach out is both a waste of money and bad for the enviorment. Maybe there are some soil test readers here, If not, I'd suggest you re-do the test with Logan Labs and pay for them to make recommendations. Just my two cents....See Moresoil for grass, with soil test results
Comments (18)toxcrusadr-- the *path* is supposedly 8' wide, not the spreader. And the path does seem to be... I didn't stop to measure it though : ) If that sounds funny though, I wonder if that's why I ran out of fertilizer sooner than I expected to... I'm not sure I'm up to all that calculating-- can I assume though that the higher the number, the more grains it puts out at once? The people at the store (who seem very knowledgeable, I mean) said that I want one bag to cover a quarter acre. Which I think is about the amount of grass we have, maybe a bit more. We have a tiny bit over a half acre total but that of course includes the house/pool/driveway/pavers out back etc. Regardless, that bag lasted for a bout 1/3 of my grass. I went back for 2 more bags and changed the setting on the spreader-- think from 8 to 6 and got some more range out of it. Still had to open the third bag though. Sigh. Maybe I should look for a highly rated spreader and buy that. This one was borrowed from my brother-in-law and I think I have found it online and if I'm right about which it is (the Scotts classic drop spreader), I see that it gets bad reviews, lots of them. Same reasons. I'm learning a lot of lessons lately, the hard way... Isn't that supposed to be the best way though? Or something. Oh and just FYI, that's only one of several bare patches. And there are plenty of weeds, trust me. It's hard to tell from this one picture but they are everywhere, all kinds. Some areas have less but some areas are also straight weeds so it all balances out, ha....See MoreSoil testing before planting?
Comments (7)I have to disagree. Saying that California soils have everything you need is an oversimplification. Soil chemistry isn't cookbook ingredients-simple; rather, soil chemistry involves relative ratios of the important nutrients. A soils report provides a useful education, but like so much of education these days, you'll have to pay for it. A good soils test will help you understand what your soils need and how to add those ingredients in the most cost-effective way. I can give a very concrete example. The soils in my gardens have more than adequate magnesium and calcium. In cookbook terms, the absolute amounts of Ca and of Mg are more than adequate. But the ratio of calcium:magnesium is important. Why? Because chemically, the rose doesn't distinguish between the two. As a result, a surfeit of magnesium overwhelms the plant's ability to absorb calcium. Calcium is essential to plant usage of nitrogen. Therefore, an objective of all fertilizing in my garden is adding calcium and never adding magnesium to improve the ratio of Ca:Mg. Given the choice, I will fertilize with compounds that have calcium and avoid every compound that has magnesium in it. I will also add gypsum every year, with the same objective. Without the guidance of a soils scientist, I wouldn't know that I had the choice of a calcium compound that can buffer the low pH in my garden or a calcium compound to adding nitrogen to my garden. If I had only 3 or 4 roses, none of this would matter much. But since I planted my entire garden which includes hundreds of roses from scratch, this information has been invaluable. If I weren't aware of this issue, I wouldn't understand why the roses I planted in unamended soil (before I had the full soils report) show the foliage symptoms they do. There are important issues throughout California related to soils pH. In SoCal, it's high pH. In NorCal, it can be low pH. Balancing pH is important. With low pH/high acid soils, a non-nutrient that can have a toxic impact on many plants: Aluminum. I also now know that my soils are high in micronutrients and that I must never, ever, use fertilizer with micro-nutrients. They are expensive and a complete waste of money. Excess micronutrients can cause serious imbalances. That fantastically dark green foliage I see in my roses is actually a reflection of excessively available micro-nutrients. I say go for the soils report if you afford it. If you can't afford it, read about the soils in your area and fake it....See MoreLaboratories Conducting Soil, Plant, Feed or Water Testing
