0000009913 00000 n Low CEC soils are more susceptible to cation nutrient loss through leaching. Receiving the results as an email versus waiting for them to be returned through the mail can speed up the process. Please refer to this number if you have any questions. Soil testing is also useful for identifying contaminated sites (e.g., elevated levels of lead). r Q Q Q z&. All other trademarks are the property of their respective owners. Their levels are usually present in the soil in sufficient quantity to allow for good plant growth without adding them to the soil in the form of fertilizers. D, Penn State University. Figure 1 illustrates the relative proportion of nutrient needed from either soil or fertilizer at the various soil test levels. Contestant's Number _____ Final . Your UK Soil Test Report: Use and Interpretation - KyGrains.info Interpretation of soil NO3-N levels below 30 ppm is somewhat nebulous because soil nitrogen is so dynamic. The term pH is used to express the acidity or alkalinity of the soil and is measured on a 0 to 14 scale. endobj Percent organic matter is another critical measurement - monitoring its value over time can tell you quite a bit about how well your soil management practices are working to maintain or build it (see Chatham-Kent Agri-Development article). endobj There are a variety of reporting units for soil organic matter content. In New England, atmospheric deposition resulting from combustion of fossil fuels has historically contributed significant amounts of sulfur to soil each year; however, with improved emissions control and the use of cleaner fuels, sulfur deposition has been reduced. The units used to report the analytical results are not familiar. Anything below 7.0 is acidic and anything above 7.0 is basic or alkaline. <> When values are greater than 0.60 sensitive plants (such as onions, etc.) Calcium ppm of 1400 or higher is generally right for most crops.

PDF Understanding the Numbers on Your Soil Test Report - FSA2118 Solve accurately and quickly as many as you can in the order in which they appear. In order to make use of the values in predicting nutrient needs, the test must be calibrated by conducting nutrient response research, under local conditions with representative soils ranging from deficient to adequate for each nutrient of concern. All rights reserved. Nitrate Nitrogen (NO3- N) Nitrogen is essential to nearly every aspect of plant growth. This is due, in part, to the rapid microbial decomposition rates favored by these soil conditions. Soil acidity also influences soil microbes. Understanding the numbers on your soil test report. Spanish endobj Plants only need a small amount of copper. Samples must be taken at a consistent depth and in a random nature. PDF How to Read a Soil Test Report: Step by Step - UGA This bulletin will aid farmers and all agribusiness personnel in understanding the soil test results and fertilizer recommendations provided by the Michigan State University Soil Testing Laboratory. 0000002026 00000 n Although NH soils are naturally very acidic (pH 4.5 5.5), most plants prefer a pH range of 6.0 6.5. Please note, this information is not intended as an agronomic recommendation, nor are we making any such recommendation. Dueto variations in soil proper tiesfrom one geographicregion to another,soil testing laboratoriesmay usedifferent extractant solutions . Directions: Do not turn this page until the person conducting this test gives the signal to begin. 9 0 obj Aluminum (Al) Aluminum is not a plant nutrient and at elevated levels it can be extremely toxic to plant roots and limit the ability of plants to take up phosphorus by reducing phosphorus solubility. Recommendations from the Lab are based on the crop you are growing and the year of rotation. The optimum range (or typical range in some cases) is provided in the column to the right of your results. Reading soil test results can be overwhelming and seem challenging to process. Also, if you've been given a fertilizer recommendation, it is useful to be able to double check to make sure it's in the right range. It is important, however, to be aware of the difference between ppm and lb. All products and prices are subject to change at any time and without notice. Many materials can have values above or below this 100 CCE benchmark. Five of these (iron, manganese, zinc, copper, and boron) are tested routinely. (Multiply this value by 2 to get approximate lbs per acre at a depth of 6 inches.). 0000007220 00000 n Acid-loving plants, such as rhododendrons and blueberries can tolerate moderately high aluminum levels, whereas lettuce, carrots and beets are very sensitive. Soil pH measures the acidity or alkalinity, and pH levels will range from 0-14, with <7 indicating an acidic pH, seven a neutral pH, and >7 a basic pH. When nutrients are below optimum, recommendations are based on a building approach. When sulfur levels are low, several sources of sulfur are available to ensure adequate plant nutrition including: gypsum (calcium sulfate), potassium sulfate (0-0-50) and sul-po-mag (0-0-22-11 Mg-22 S). Salts can accumulate due to excessive fertilizer applications, poor quality irrigation water, or limited rainfall. Cover Crop Confessions: Mistakes We Made and Lessons We Learned (And What We're Still Learning) Converting from conventional cropping to regenerative practices can be a challenge in the early years. per acre. 0000004250 00000 n When a soil sample is submitted to the lab, it is dried and ground and a variety of extractions are performed on small "sub-samples". 0000002564 00000 n The concentration is reported in ppm. Soil microbes are most active in warm soils (over 70F) that are moist, but well aerated, with a pH between 6 and 7. trailer Soil health tests should provide consistent, reliable results (be reproducible), and they should measure important attributes of soil functions that respond relatively quickly to management. Soil pH directly affects nutrient availability. Testimonials are not indicative of future performance or success; prices and savings may vary. Normal off-season precipitation usually will correct salt problems resulting from over-fertilization. This article covers the basics. Sulfate is also subject to leaching. The soil test value for a given nutrient does not give you the total amount of that nutrient in the soil; it instead provides an index of nutrient availability that is correlated with plant response. Most plants prefer a soil pH between 6.2- 6.5. . Lab Number is the unique identification number we use to track your sample. Plants require fairly large quantities of phosphorus, but the levels of phosphorus available to plant roots at any given time are usually quite low. 460 0 obj Native SOM content of most cultivated or developed areas of New England is almost always less than 8% and typically in the 2 to 4% range. Listen to a Daily podcast special uncovering Iran's arms links . Nitrogen is a dynamic nutrient, moving quickly in the environment from one form to another. Area Sampled is approximate area (in square feet or acres) that is represented by your sample. Several factors control the amount of SOM a soil may have, including soil texture and drainage. You can use these numbers to determine which nutrients to apply (and the amounts needed), if you want to fertilize differently than what NCDA recommends. Most soil testing laboratories tell this measurement as accessories per milliards (ppm) for nutrients other than nitrogen. endobj Active pH and buffer pH. Recommendations: Recommendations for lime and fertilizers, based upon the crop (s) you intend to grow. ft. but the local garden center only has 4-5-3 fertilizer and 6-2-1 fertilizer. Like guide willing help you understand which soil test report plus make the erkenntnisse more . Once applied, the sulfur oxidizes to sulfuric acid. The results of the laboratory analysis are often confusing. Connect with Nutrient Management Extension. Nearly all of the New England State Universities and Cornell use the Morgan extraction procedure. Exceptions are acid loving plants such as blueberries, azaleas, rhododendrons, mountain laurel and holly, which prefer pH 4.5 5.5. Spanish"@eng. The desired ppm for zinc ranges from 1.0 to 3.0. . stream Then, depending on the depth of sampling, the concentration is converted into pounds of NO3--N per acre for each increment of depth that was sampled. 0000003988 00000 n Once the soil test is conducted and the results are available, the ability to interpret the results and follow the recommendations is an important . When soil pH is maintained at the proper level, plant nutrient availability is optimized, solubility of toxic elements is minimized, and beneficial soil organisms are most active. The area where crop response begins to reduce becomes the beginning of optimum. When to Fertilize -Vegetables -at planting time and again 3-6 weeks later if needed -Annuals -at planting time; may need additional N by mid-summer -Fruit trees, grapes, berries -typically early spring -Trees, shrubs, perennials -spring IF NEEDED -Fescue Lawns -Fall and early Spring -Bermuda/Zoysia: Summer At high levels, lead is toxic to humans, and young children are at the highest risk. Understanding Your Soil Test Results [fact sheet] - Extension The lab determines buffering capacity and lime requirement by estimating the exchangeable acidity. The soil pH scale is measured from 0 to 14. To get reliable results and appropriate fertilizer and lime recommendations, it is important that you submit a representative soil sample from your lawn or garden. Magnesium is often adequate in soils with a pH 6.5 and higher, though magnesium at 100 ppm or more is acceptable. How to Read a Soil Test Report: Step by Step Check the "crop" being grown under client's name. Some phosphorus is present as part of soil organic matter and becomes available to plants as the organic matter decomposes. 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. Despite the low SOM content of many New England soils, it is an important component of soil for nutrient supply, water holding capacity, cation exchange capacity, and soil structure. Your report includes the base cation saturation values observed for your sample and the ranges typically observed in New England soils. Iron ppm of 10-20 is typically common on most soils. The lab uses the Modified Morgan extraction procedure, originally developed at the University of Connecticut in the early 1930s for use on New England Soils. Soil NO3-and NH4+levels can fluctuate widely with soil and weather conditions over very short periods of time. Contact the laboratory or visit the website for more information on this test.

The weight of this sample is recorded and used to calculate nutrient concentration on a mass basis (e.g., mg of nutrient per kg of soil). Ukraine war latest: Russia claims it has thwarted major Ukrainian Organic Matter - That portion of the soil made up of dead and decayed plant and animal parts. Recommendations: Recommendations for lime and fertilizers, based upon the crop(s) you intend to grow. The extractants pull the easily available and some of the moderately available nutrient from the soil. The bulk of the report is composed of the results of tests you specified, test interpretations, and recommendations. More information on calcium carbonate equivalency and liming can be found in the Penn State Extension articleSoil Acidity and Aglime. The results provided on your soil test report reflect the immobilie of the sample you submitted and the testing procedures used . The range for sodium in most common soil types is typically 80-120 ppm. 10 0 obj The cations calcium (Ca2+), magnesium(Mg2+), potassium (K+), hydrogen (H+) and aluminum (Al3+) account for the vast majority of cations adsorbed on the soil colloids in New England soils. Grain market advisory services are offered by FBN CM LLC and are only available where FBN CM LLC is licensed. Please consult the label for the most complete and up-to-date information about any referenced product. The Pre-sidedress Soil Nitrate Test (PSNT) has been shown to successfully predict sidedress fertilizer N needs for a few crops (e.g., corn, pumpkin, peppers, cabbage), but the PSNT requires stricter sampling (depth and timing) and handling than a standard soil fertility sample.

Lead is naturally present in most New England soils at low concentrations (15-40 ppm total lead). Soil testing is an important tool for growing healthy lawns and gardens. Aluminum sensitivity varies greatly with plant type. The soil analysis report that you will receive back from the lab should consist of all the attributes of the soil test you selected when you sent off your samples. You may notice that nitrogen (N) is not measured. Nutrient recommendations are reported in section 3 of the soil test report. For example, if you had a field sitting at 10 ppm P and 80 ppm K, P and K above crop removal could be applied over a number of years to reach targets of 15 ppm P and 115 ppm K. Variable rate technology is available to apply these nutrients. Most homeowners find it difficult to translate the results and end up over fertilizing . Depending on the lab you use, each OMAFRA-accredited test value should also have a code associated with it. Your soil test report recommends applying 10 lbs. This ability, however, is limited and variable. Still, sulfur deficiencies are rare in New England and an optimum range for Modified Morgan extractable sulfur has never been identified. Soluble Salts Soluble salts, present in many commercial (and some natural) fertilizers and deicing products used on sidewalks and roads, can cause severe water stress and nutritional imbalances in plants. Regenerative Agriculture Archives - Noble Research Institute Properly limed soils with constant and adequate moisture will normally supply sufficient calcium to plants. There are 80 problems. Sandy soils with very low CEC will tend to lose substantial quantities due to leaching and will require more frequent applications of fertilizer. For example, a potassium soil test value of 193 ppm equates to 386 lbs/acre of "exchangeable K" in the top six inches of soil. By convention, potassium recommendations are expressed as K2O to correlate with fertilizer analysis. Depending on the results of the Lead Screen, a series of recommendations will be given to minimize any risks that may be present.
