Statement of Compliance The George Mason University (GMU) agrees to comply with all requirements stated in the Nutrient Management Training and Certification regulations 43VAC50-85, and to follow recommendations for turf fertilization and management is described in the Virginia Nutrient Management Standards and Criteria, revised July 2014. This includes implementing the Nutrient Management Plan provided and maintaining fertilization records. All nutrient applications performed by GMU Staff or associated contractors shall comply with the provisions of this Nutrient Management Plan as of August 14, 2024. This Nutrient Management Plan is effective for three years or until changes in Nutrient Management practice have taken place or major changes in grounds conditions on site occur.

Site Location and Description George Mason University (GMU) owns property located in Fairfax county bordering Belmont Bay. The property has been referred to as Point of View and holds tall fescue on majority of the site. The site is bordered by heavily wooded forest and a few ornamental and flower bed plantings. Point of View drains within the Occoquan River-Belmont Bay watershed (PL48) and ultimately drains to the Middle Potomac- Anacostia-Occoquan (HUC: 02070010).

Stormwater Drainage: There are no underground stormwater conveyance systems present around the GMU Point of View Site.

Soils: The National Resource Conservation Service (NRCS) soil survey map depicts 3 distinct soil series within the Campus site. Majority of the soils present on site are considered well drained loamy soils and none are listed as high as environmentally sensitive seen in Table 1-4 of the Virginia Nutrient Management Standards and Criteria, revised July 2014. Furthermore, there were no environmentally sensitive areas identified during the site visit of April 12th, 2024.

Streams and Wetlands: The Point of View Site is surrounded by wetlands and streams on three of four sides of the property. The Point of View property comes in contact with Belmont Bay from the West and is bordered by a stream residing in Mason Neck State Park from the South and East.

Fertilization Season

The recommended season of application for nitrogen fertilizers for tall fescue, which is categorized as a cool season grass begins February 27 and ends December 6, as shown in Table 2-1 Fertilization Season

Cool Season Application Window, Turfed Areas

Onsite Spring April 10 February 27

Fall October 25 December 6

Soil Sampling Method, Areas of Management, and Recommended Amended Soil Sampling Narrative: There were a total of 2 soil samples collected from preselected locations surrounding areas of the GMU property Point of View. Each sample taken followed the Soil Sampling method recommended by Virginia Tech Soil Laboratory. The samples were then sent to the lab to receive the most accurate fertilizer application required.

Nutrient application will not take place on frozen or snow-covered ground. Any fertilizer that has been displaced onto impervious surfaces such as parking lots, or pedestrian walkways shall be swept or blown back into the pervious area. Additionally, fertilizer will not be used as ice melt. Never exceed 0.9 pounds of water-soluble nitrogen in any single application. Apply phosphorus only when a soil test determines it is needed. All ornamental landscaping is to receive no nutrients.

Soil Testing Procedure for Virginia Tech Laboratory

Important:

For test results to be meaningful, use extreme care when taking soil samples. Each sample represents many tons of soil in your lawn or garden. Test results cannot be any more accurate than the sample submitted to the laboratory. Do not take samples when the soil is extremely wet.

Sampling Instructions:

Divide your lawn or garden into sampling areas. Each area should be uniform in the kind of soil and in the past fertilizer and lime treatments it has received. An example would be separate samples (areas) for front and back lawns. For shrubs and trees, select an area from the trunk to the outer edges of the branches.

Take a separate sample from each area as shown in the diagram below.

Use the following procedure for each sampling area:

A Take samples with a trowel, shovel, spade, or auger. Make a vertical cut 4" deep for lawns, or to plow-ing depth for gardens, and push the soil aside. Then cut a thin slice from the side of the opening that is of uniform thickness, approximately 2" in width, and extending from the top of the ground to the depth of the cut. Scrape away or discard any surface mat of grass or litter and place the slice of soil into a clean bucket or other container. Follow this sampling procedure in 10 or more different locations within each sampling area, each time placing the resulting soil in the same container, giving you a composite sample.

B Thoroughly mix the soil from the composite sample and then fill the sample box to the top with the mixture. Fill in the information requested on the side of the sample box, including sample number, complete the other side of this sheet, and send sample, sheet, and payment directly to the Soil Testing Laboratory.

For additional sampling instructions go to www.soiltest.vt.edu.

Site Sampling Example Pattern

5) Remove the penetrometers safety lock and move to the first testing point.

6) Look over the penetrometer for possible signs of damage; confirm that the metal rod is not warped and that the PSI gauge reads 0, as seen in Figure 2.

Soil Penetrometer PSI Gauge

7) Push the device into the penetrometer testing location at a constant rate. Monitor the pressure gauge located on the top of the device, as seen in the image above.

STOP testing and chose a new testing location.

8) the tip used with the appropriate scale on the gauge.

9) As force is applied on the penetrometer, the gauge needle will show the soil compaction pressure in pounds per square inch (psi). If the penetrometer gauge reaches 200 psi this is the top of the layer of compaction and should have its depth recorded, 200 psi or more is not reached for the full length of the rod there is no layer of compaction to the depth tested.

10) If the device is pushed fully into the ground and does not drop below 200 psi the layer of compaction continues.

11) If the gauge needle drops below 200 psi after reaching 200 psi the layer of compaction has ended, this depth should be recorded.

12) Once the top and bottom of the layer of compaction is known the depth of the compaction layer can be computed and recorded.

13) Steadily remove the device from the ground as to not detach the tip, once removed clean off the device with a damp rag to allow for a more accurate reading for each test.

14) Move to the next point and Repeat steps 8 to 16 until all 5 points have been tested and their data recorded.

15) Once the test is completed and the data reviewed for inaccuracies clean off the device using a damp rag.

16) Unscrew the tip and fasten it to the clip located near the gauge and handles.

17) Replace the safety lock midway on the rod to protect the device during transit.

Penetrometer Note:

The Penetrometer test is used to determine the depth at which the soil layer of compaction exists. Each soil sample location received five penetrometer tests randomly selected within the region. All values are given in inches at which the layer of compaction within the soil was detected. Annual aeration of soils is recommended.

Aeration of cool season grasses should take place in early Spring or Fall. Aeration for warm season grasses should take place in later spring months.

Maintenance of Plan This nutrient management plan will be maintained by GMU and will expire on August 14, 2027. As part of the provided plan, fertilizer application records should be recorded and maintained within the provided document (see Appendix C). Soil samples must be collected once every three years to continue good practice and maintain the provided plan. If significant changes to the site have been made, the plan provided is required to be updated by a Virginia Certified Nutrient Management Planner. Significant changes include: Changing turf species, adding significant soil amendments, expansion of the area to be included under this nutrient management plan, or other changes that could alter nutriment recommendations.

Nutrient Application and Special Conditions There are no existing underground stormwater conveyance systems onsite.

Nutrients are not to be placed new existing wetland nor streams to avoid runoff into nearby waterways. If Nutrient applications are found on impervious surfaces, they are to be blown or swept back into the pervious areas. Nutrient applications should not take place during stormwater events or be competed when stormwater events contributing to large runoff are anticipated in the near future.

Conclusion

Soil samples seen in Figure 5 were taken at the Point of View property and the surrounding area have been sent to the Virginia Tech Soils Laboratory. In order to provide a sufficient solution to the loss of nutrients in the soil, the lab has tested and provided recommendations to apply lime and fertilizer to the specified areas seen in Figure 4. The results were then interpreted, and solutions were provided in the report above under the Soil Group Application section. It is the opinion of the submitting engineer that the recommendations of lime and fertilizer applications provided are more than adequate for the proposed Nutrient Management Plan.

APPENDIX A

The accompanying Soil Test Report (and related sup-plemental Soil Test Notes) will help you assess your plant’s need for fertilizer and lime.

The “History of Sampled Area” section restates the in-

Sheet you submitted with the soil sample.

The “Lab Test Results” section shows the relative availability of nutrients numerically and if appro-priate, as a rating. The rating may be interpreted as follows: L=Low, M=Medium, H=High, VH=Very High, EH=Excessively High (soluble salt test only), “+” or “-.” When soils test Low, plants almost always respond to fertilizer. When soils test Medium, plants sometimes respond to fertilizer and a moderate amount of fertilizer is typically recommended to maintain fer-tility. When soils test High to Very High, plants usu-a nutrient, the adequacy of that nutrient in the soil for

The following is an explanation of the symbols and ab-breviation used in the report:

Report Symbols and Abbreviations

P = phosphorus K = potassium

Ca = calcium Mg = magnesium

Zn = zinc Mn = manganese

Cu = copper Fe = iron

B = boron SS = soluble salts lb/A = pounds per acre ppm = parts per million meq = milliequivalent g = gram pH = acidity Sat. = saturation

N = nitrogen P O

K O = potash % = percent

Est-CEC = estimated cation exchange capacity

AG = agricultural limestone (dolomitic or calcitic)

Fertilizer Recommendation The fertilizer recommendations may be used for the same crop for two to three years. After this time, it is changes have occurred in nutrient levels. When the soil tests Very High for phosphorus or potassium and no fertilizer for these nutrients is recommended, you should retest the following year to determine if fertil-izer will be needed. Due to the variability associated with sampling, fertilizer application rates may be var-ied by a plus or minus 10 percent.

No soil test is performed for nitrogen because this ele-ment is too mobile in the soil for laboratory results to be useful. Nitrogen fertilizer recommendations are based on the crop/plant to be grown, the previous crop, and when applicable, the soil’s yield potential. Comments on the report and associated Notes, if any, will have further information regarding nitrogen.

Lime Recommendation soil acidity and should last two to three years. After that time, you should have the soil retested. The measured soil test levels of calcium and magnesium are used to neither dolomitic nor calcitic lime is mentioned, or “Ag” type or “agricultural” limestone is stated on the report, then it does not matter which type is used. When no provided regarding the last lime application, the lab as-sumed you have not applied lime in the past 18 months.

advice on adjusting the lime recommendation to take into consideration recent lime applications. Do not over lime! Too much lime can be as harmful as too little. For best results, apply lime, when possible, several months ahead of the crop/plant to be planted to allow time for more complete soil reaction.

Soil pH (or soil reaction) measures the “active” acid-ity in the soil’s water (or hydrogen ion activity in the

1:1, volume to volume ratio of soil material to distilled water.

Virginia soils naturally become acidic, and limestone periodically needs to be applied to neutralize some of this acidity. A slightly acid soil is where the majority of nutrients become the most available to plants, and where soil organisms that decompose organic matter and contribute to the “overall health” of soils are the most active. When a soil is strongly acidic (< 5.0-5.5), limited by aluminum toxicity. When soils are over-limed and become alkaline (> 7.0), micronutrients, such as manganese and zinc, become less available to plants.

For most agronomic crops and landscaping plants, lime recommendations are provided to raise the soil pH to a slightly acid level of between 5.8 and 6.8. Blueberries and acid-loving ornamentals generally prefer a 4.5 to

5.5 pH, and an application of liming material is sug-gested when the soil pH drops below 5.0. For the ma-jority of other plants, lime may be suggested before the pH gets below 6.0. This is to keep the soil pH from dropping below the ideal range, since lime is slow to year when the lime is not incorporated into the soil.

range, then sometimes an application of sulfur is rec-ommended to help lower the pH faster; however, most of the time, one can just let the soil pH drop on its own.

to provide an indication of the soil’s total (active + reserve) acidity and ability to resist a change acidity increases and more lime is needed to raise the soil pH. A sandy soil and a clayey soil can have the same soil pH; however, the clayey soil will have greater to the sandy soil, and the clayey soil will require a greater quantity of lime to be applied in order to raise the soil pH the same amount as the sandy soil.

Nutrients that are available for plant uptake are extracted from the soil with a Mehlich 1 solution using a 1:5 vol:vol soil to extractant ratio, and are then

Mehlich 1 level of phosphorus from 12 to 35 pounds per acre (lb/A) is rated as medium or optimum. A medium level of potassium is from 76 to 175 lb/A. Medium levels of calcium and magnesium are 721 to 1440 and 73 to 144 lb/A, respectively. Calcium and magnesium are normally added to the soil through the application

P, K, Ca and Mg to cause a reduction in crop yield or plant growth. Levels of micronutrients (Zn, Mn, Cu, Fe and B) are typically present in the soil at adequate levels for plants if the soil pH is in its proper range. See Soil Test Note 4, at www.soiltest.vt.edu/report-notes, Soluble Salts (S.Salts) or fertilizer salts are estimat-ed by measuring the electrical conductivity of a 1:2, to plants may start at a soluble salts level above 844 ppm when grown in natural soil, especially under dry conditions and to germinating seeds and seedlings.

Established plants will begin to look wilted and show signs related to drought. This test is used primarily for greenhouse, nursery and home garden soils where very high application rates of fertilizer may have led to an excessive buildup of soluble salts.

Soil Organic Matter (SOM) is the percentage by weight of the soil that consist of decomposed plant and animal residues, and is estimated by using ei-

Generally, the greater the organic matter level, the bet-ter the overall soil tilth or soil health, as nutrient and water holding capacities are greater, and improved aer-ation and soil structure enhance root growth and mi-crobial activity. The percent of organic matter in a soil organic matter levels from 0.5% to 2.5% are ordinary for natural, well-drained Virginia soils. A soil organic matter greater than 3% would be considered very high

Due to relatively large amounts of organic materials being commonly added to gardens, the soil organic matter in garden soils can be raised to greater than 5%.

The remaining values that are reported under the “Lab Test Results” section are calculated from the previous measured values and are of little use to most growers.

Conversion Factors

Estimated Cation Exchange Capacity (Est-CEC) gives an indication of a soil’s ability to hold some nutrients against leaching. Natural soils in Virginia usually range in CEC from 1 to 12 meq/100g. A very sandy soil will normally have a CEC of 1 to 3 meq/100g. The CEC value will increase as the amount of clay and or-ganic matter in the soil increases. This reported CEC is an estimation because it is calculated by summing the Mehlich 1 extractable cations (Ca + Mg + K), and verting to units commonly used for CEC. This is also pH. This value can be erroneously high when the soil pH is alkaline (greater than 7.0) or soluble salts level is high.

The percent Acidity is a ratio of the amount of acid-that occupy soil cation exchange sites to the total CEC sites. The higher this percentage, the higher the amount of reserve acidity in the soil, and the higher the amount of acidity there will be in the soil solution and the lower the soil pH will be.

The percent Base Saturation is the ratio of the quantity of non-acid generating cations (i.e., the exchangeable bases, Ca, Mg, and K) that occupy the cation exchange (CEC) sites.

The percent Ca, Mg, or K Saturation refers to the rela-tive number of CEC sites that are occupied by that par-ticular nutrient and is a way of evaluating for any gross nutrient imbalance.
