I think this makes sense to me. Sulfur is measured as sulfate, which is the available form of sulfur the plant can use. 3. A community for the DIY lawn enthusiast... Post

So My calculation would be higher since the applied amount of Ca was only calculated on 2/3 acre slice furrow.

There are three common analysis methods to evaluate the presence of soil phosphorus. <> Manganese at 8-11 ppm is typically sufficient. Awesome info Ridgerunner and g-man!

With proper soil drainage accompanied by rainfall or irrigation, the salt can sometimes be flushed out of the root zone to correct the problem. The S3M test which is what I got costs $16.50 from the Iowa lab and includes those recommendations. Iron ppm of 10-20 is typically common on most soils. Salts can accumulate from excessive fertilizer applications and poor quality irrigation water, and where rainfall is limited. 7 0 obj by Pete1313 » Fri Mar 30, 2018 12:06 pm, Post

The soil test measures the exchangeable potassium in the soil. If 12 ppm of NO3 is reported, then multiplied by 2.4 equates to 28.8 pounds of nitrate nitrogen in the soil, which means your nitrogen applied should be effectively be reduced by 28.8 pounds from total N needed to grow your next crop.

/OPM 1 But each laboratory can adjust these recommendations based on your specific needs and their expertise. This measures the electrical conductivity of the soil solution to determine the risk of salt injury to plants. endobj 3 0 obj Soils with 25 to 35 ppm P is typically adequate on most soils. 4 0 obj

Mn availability is influenced by soil pH, and low pH can increase Mn availability, while high pH can lessen it. endstream

I changed up my soil test procedure this year by sampling the whole soil core from 0-4" opposed to just the 3-4" depth in previous years. This measures the electrical conductivity of the soil solution to determine the risk of salt injury to plants. With proper soil drainage accompanied by rainfall or irrigation, the salt can sometimes be flushed out of the root zone to correct the problem. This part of the analysis is primarily for use in repairing saline or alkali soils. Soils high in sodium (Na) are referred to as sodic soils. stream >> <] /BitsPerComponent 1/Interpolate false/SMask 11 0 R/Filter/FlateDecode/Length 12>>

Look for for a minimum of 165-220 ppm to supply the needed amounts of potassium to maximize production. ��i�� y��+!��iU�)�Åa��ΜV� (B��0 �&���l�����p|�>����H�\D�;xZ�gypݱ��\���Kc�B�9d#9*'�2�J)Z>g��k��b7�EY�(?��s�ʻR��n��p����* 3 0 obj Waypoint’s agricultural labs are strategically located to provide its clients with timely and accurate analytical data for making decisions that positively impact sales and profits.

Don’t be too concerned about correcting soluble salts unless they are reported over .75 mmhos/cm (millimhos per centimeter, which is the basic unit of measure of electrical conductivity in soil) on your analysis.

With a low pH (less than 6.0), it may be necessary to apply calcium to adjust pH upward. This a measurement of the amount of free lime in the soil. by Ridgerunner » Fri Mar 30, 2018 1:59 pm, Post

Mark Cullen explains how to use a soil test kit and how to amend your soil based on the test results. One thing I noticed odd in the report was that they used m3 for phosphorus given the pH being 7.4. That is the only reason it is reported on your soil test analysis, and only on soils with a pH below 5.8. Testing Services. endobj Sample depth 0-4".

%PDF-1.5 stream Also what do you make about the different recommendations for a bluegrass lawn compared to a athletic field(addition of .5 lb/M of P2O5 and .33 lb/M of S)? Sulfate is also subject to leaching. x�+T06�3 D�%��{�&��(��+ ҽ � So although I am only interested in the 0-4" depth it is assumed that the Ca is not just going to be in the 0-4" range. endobj

This can include a fertilizer recommendation for achieving the yield goal of the commodity to be grown, which are usually based on local university research for your particular area.

Is the 1.0N, 0.2P, 0.5K based on removing clippings or mulching them back in?

The reading can be important in your herbicide selection and fertilizer applications, so that you can avoid product tie-ups with the calcium present—which would render it ineffective and unavailable to your plants.

Organic matter accumulation is a slow process. So far I've discovered a couple of way to determine how much the lawn uses of each of the elemental nutrients from the MLSN model.

Magnesium is often adequate in soils with a pH 6.5 and higher, though magnesium at 100 ppm or more is acceptable. /SM 0.001 I think the approach of using next year results to keep tweaking is the best.

Soil test levels should be maintained in the optimum range. 12 0 obj Click the image to download our soil test submission form which includes macro minerals and 6 trace minerals. Soluble salts are largely affected by environmental conditions—soils that contain high salt content are called saline soils (NaCl). But remember, the analysis is only as reliable as the soil sample collected. DO NOT SEND PAYMENT WITH SAMPLES. Is it just that more root mass is located within the 3-4" range (if that's actually true)? the analysis is only as reliable as the soil sample collected. y�TJQ�e������I�}�����A{�.��ل!��Ta���X�_n Mostsoils low in magnesiumare often acidic and low incalcium. I don't remove my clippings. Calcium is typically plentiful in soils with pH of 6.0 and higher; however, calcium can be applied as gypsum and not affect soil pH.

Lowering the soil pH is a more difficult and expensive task—sometimes, an application of elemental sulfur can be used to lower soil pH. In your calculation it is amount of Ca applied to a full 1 acre slice furrow and then ÷ 2 for ppm. Water Analysis Waypoint Analytical. Please consult the label for the most complete and up-to-date information about any referenced product. I also changed labs and went with Waypoint Analytical. I like the adjustment/thinking of what the lawn uses plus what it has. Always consult an independent agronomist if you are unsure of agronomic decisions on your operation. DO NOT SEND PAYMENT WITH SAMPLES. >> Instead, when a soil’s pH is below 5.8, this characteristic is used to estimate the lime (Ca) required to correct the soil pH to around 7.0. your thoughts on soil sample depths and how they changed around the numbers in my case and also what you think about the Waypoint Analytical Soil Test format. Soils with a high percent base saturation can be more fertile because they often have a higher pH, and can contain greater amounts of these nutrients for use by plants. The 0.2P and 0.5K are for removed clippings.

The fields you need to fill out are highlighted. Thanks for the detailed response. stream

Also based on the Ca/Mg ratio, and that the Ca is in the medium range(per the test) what do you think about adding some gypsum to the amendment list this year?

by Pete1313 » Fri Mar 30, 2018 1:15 am, Post The majority of the copper deficiencies occur in highly acidic soils. << endstream This can include a fertilizer recommendation for achieving the yield goal of the commodity to be grown, which are usually based on local university research for your particular area. Regarding my K, it looks like it is right in the sweet spot at 178ppm so their 1 lb/M of K2O recommendation is most likely accounting for the crop using some of the K when applying 3 lbs/M of N. And since I am going to apply more N this year since it is a first year lawn, I will most likely need to up the amount of K2O and then monitor whether the amount on next year's test goes up or down and adjust to estimate the usage rate of my lawn over time?
