Waypoint Site Soil | Report 26-251-0004 | September 14, 2026
2,000 sq ft / 6-inch sampled depth. General growing. Area and depth were supplied by the customer.
| Soil pH | 4.8 | Strongly acidic |
| Available nitrogen | 7 ppm | Nitrate-N 6 ppm; ammonium-N 1 ppm |
| Phosphorus | 4 ppm | Olsen extraction |
| Potassium | 41 ppm | Sodium chloride extraction; disclosed with sufficiency factor 0.5 |
| Calcium / magnesium | 246 / 83 ppm | Separate saturation-extract readings also shown |
| Manganese | 7.1 ppm | DTPA extraction; elevated in this strongly acidic soil |
| Organic matter | Not reported | No measured starting percentage |
| Sample passing 2 mm test screen | 21% | Only 21% of the submitted soil passed through the test screen |
| Qualitative lime | Low | No quantitative lime requirement |
Waypoint rates available N at 7 ppm and phosphorus at 4 ppm, measured by Olsen extraction, as very low. Its pH graph shows 4.8, strongly acidic. Waypoint's K sufficiency factor is 0.5 relative to its ideal factor of 1.0. The 41 ppm sodium chloride-extracted K result and separate 0.1 meq/L saturation-extract result are distinct. The disclosed result and sufficiency factor support QMA's calculation of the first potassium amendment; no ppm value is converted into a claimed nutrient stock. The 7.1 ppm DTPA manganese result is elevated in strongly acidic soil: excess available manganese can reduce plant vigor and damage foliage. QMA recommends no manganese addition, staged lime correction to reduce manganese availability, and a comparable pH-plus-DTPA-manganese retest. Pages 2–5 give the first application and its evidence.
First application across 2,000 sq ft | Target pH 6.5
100 lb agricultural limestone, 90% CCE. 5 lb per 100 sq ft. Incorporate into the available 6-inch layer. Retest before another application.
40 lb bone meal 3-15-0. Before planting. Supplies 6.0 lb P₂O₅ and 1.2 lb N.
40 lb feather meal 12-0-0. Apply 20 lb before planting; reserve 20 lb for active growth about 4–6 weeks after planting.
18.2 lb langbeinite 0-0-22. Before planting. Supplies about 4.0 lb K₂O, 1.97 lb Mg and 4.0 lb S.
This plan uses a staged correction because pH and nutrient levels are very low. Retest after 3–6 months before deciding on further lime, phosphorus, or potassium. See Page 5 for details.
The first application is staged to address the measured deficiencies and acidity. Adding more P, K, Mg, S, manganese or lime now could create imbalances or exceed this plan; wait for a comparable soil test and QMA review before considering more. Keep acid-loving plantings separate because the target pH 6.5 is not suited to them.
Compost is not included in these calculations. See Page 5 for how QMA can review compost test results and your target organic-matter percentage.
Amounts cover 2,000 sq ft | Use the analyses and quantities listed below
100 lb agricultural limestone. Broadcast at 90% CCE; incorporate into available 6-inch layer and water. Use 90% CCE agricultural limestone only. If this limestone is unavailable, contact QMA for a recalculated rate before applying; hydrated lime is a different material and is not interchangeable at the stated rate.
40 lb bone meal + 18.2 lb langbeinite. Broadcast uniformly and incorporate into the root zone. Keep concentrated langbeinite away from seed and roots.
20 lb feather meal. Broadcast and incorporate; reserve the remaining 20 lb.
20 lb feather meal. About 4–6 weeks after planting, if growth is underway, spread evenly, avoid contact with tender plants, and water. To keep this dose aligned with active nutrient uptake, reserve it until growth is underway rather than applying it long in advance to bare soil.
Retest after 3–6 months. After lime reacts, sample the same 6-inch depth for pH, nutrients and DTPA manganese by comparable methods. Record quantities, dates, planting and compost. Base further lime, P and K on the results.
Documented first-application nutrient balance
Across 2,000 sq ft (0.04591 acre), QMA selects 6.00 lb N, 6.00 lb P₂O₅ and 4.00 lb K₂O: 130.7, 130.7 and 87.1 lb per acre. These applied masses do not predict soil-test ppm changes. Nitrogen follows the OSU general vegetable-garden annual benchmark of 3 lb per 1,000 sq ft. P falls within a published low-Olsen-P potato example; that crop example is context, not this site's calibration. The first phosphorus and potassium rates use the disclosed laboratory information and QMA's documented interpretation for this site. Retest before further K. No crop-specific target is claimed.
| Amendment | Calculation | Accounted contribution |
|---|---|---|
| Bone meal 3-15-0 / 40.0 lb | 6.00 lb P₂O₅ ÷ 0.15 = 40.0 lb | 6.00 lb P₂O₅ and 1.20 lb N |
| Feather meal 12-0-0 / 40.0 lb | (6.00 − 1.20) lb N ÷ 0.12 = 40.0 lb | Remaining 4.80 lb N |
| Langbeinite 0-0-22 / 18.2 lb | 4.00 lb K₂O ÷ 0.22 = 18.18 lb | About 4.00 lb K₂O |
At catalog analysis, 18.2 lb langbeinite supplies 1.97 lb magnesium (10.8%) and 4.00 lb sulfur (22%). Bone meal supplies calcium; its amount depends on the selected label. No separate Mg, S or Ca product is assigned.
For 2,000 sq ft: 20 × 5 lb per 100 sq ft = 100 lb of 90% CCE limestone initially. This is the lower end of OSU Extension’s general incorporated-garden starting range. It is not a calculated full lime requirement: texture, OM and buffer/lime-requirement measurements are unavailable. Retest pH after 3–6 months; any further lime is a new decision based on response.
Report 26-251-0004 | Basis, limitations and customer choice
Compost may improve soil structure and organic matter content, but nutrient and liming effects vary by source. QMA’s example plans neither credit nor subtract compost contributions; amendment amounts are based on the soil test only. If you provide a compost test and your target organic-matter percentage, QMA will review the combined contributions and adjust the plan at no charge.
Retesting is not a routine QMA requirement. In this case, strongly acidic pH and very low nutrients warrant a staged correction. Retest after 3–6 months at the same 6-inch depth using comparable methods before deciding on further lime, phosphorus, or potassium.

Phosphorus-test methods and crop calibrations vary with soil and climate. OSU’s Oregon guidance distinguishes acidic, wetter western Oregon soils (Bray P1) from alkaline, drier eastern Oregon soils (Olsen P); some drier eastern Oregon areas may resemble arid parts of California more than wetter Pacific Northwest conditions, so these regional patterns should not be generalized across the West. For this sample, Waypoint’s Anaheim agronomist affirmed that Olsen P remained appropriate for interpreting the report at pH 4.8; this judgment is specific to this case. The disclosed laboratory information supports QMA’s first phosphorus and potassium calculations for this site. Waypoint disclosed sodium chloride extraction and a 0.5 sufficiency factor for 41 ppm K (1.0 ideal); the initial langbeinite rate is a staged calculation, with later decisions guided by follow-up results. Its approximately 4.00 lb K₂O, 1.97 lb Mg and 4.00 lb S contributions are accounted for. Select products with labels matching the stated N-P-K analyses and limestone CCE; if a label differs, have the rate recalculated before use. Compost and other nutrient products can add variable nutrient and liming contributions, so ask QMA to review their combined amounts before adding them. Retesting should guide any later decision to add lime, P or K; keep records of application dates and amounts. QMA’s regular plan also screens for nutrient excess: when method-matched phosphorus or potassium is above its sufficiency range, QMA notes the excess, explains that more is unlikely to improve growth and may increase runoff risk (P) or calcium/magnesium imbalance (K), sets that nutrient to zero, restricts manure, compost and other nutrient sources until analyzed, and recommends suitable harvest-and-remove, erosion protection and retesting. Acid-soil manganese is managed by no manganese addition and staged pH correction, not crop removal. Crop-specific plans may differ.
