What N-Rich® Delivers Per Application
Applied at an average of 1.5 tonnes per acre depending on your soil test results and crop plan, every tonne of N-Rich® puts real dollar value back into your soil:
Lime (CaCO₃)
$36.30/tonneThe #1 reason farmers choose N-Rich. 23% lime equivalency corrects soil pH in 2–4 weeks — not the 6–8 months you'd wait with conventional ag lime at $40/MT. On Lambton County's clay-heavy profiles, that speed matters.
Magnesium (Mg)
$40.40/tonne5% magnesium — critical for chlorophyll production and often deficient in acidic, clay-heavy soils around Petrolia and Wyoming. Worth $40.40/tonne vs. buying K-Mag at $850/MT separately.
Sulphur (S)
$42.55/tonne1% sulphur supports protein synthesis in soybeans and nitrogen uptake in corn. Worth $42.55/tonne vs. calcium sulphate at $540/MT.
Potassium (K₂O)
$36.52/tonne2% potassium for stalk strength in corn and overall plant health across your rotation. Worth $36.52/tonne vs. potash at $690/MT.
Phosphorus (P₂O₅)
$22.60/tonne1% phosphorus — especially valuable in Lambton County soils where pH-locked P is common. Worth $22.60/tonne vs. MAP at $1,273/MT.
Nitrogen (N)
$17.03/tonne1% supplemental nitrogen to support early crop growth and reduce starter fertilizer needs. Worth $17.03/tonne vs. urea at $785/MT.
Plus 2% organic matter per tonne — improving soil structure, water-holding capacity, and microbial life with every application. For Lambton County's clay-heavy soils, the organic matter is especially valuable. No commercial equivalent typically purchased — it's a bonus.
Why Lambton County Farmers Choose N-Rich®
Lambton County's clay-heavy soils compact easily, drain poorly, and run acidic under continuous corn and soybean production. When soil pH drops below the optimal range, nutrient availability declines — even if the nutrients are physically present. Your fertilizer dollars stop working as hard as they should. Phosphorus locks up. Microbial activity slows down.
N-Rich® solves multiple problems in one application. The 23% lime equivalency begins correcting soil pH in 2–4 weeks — fast enough to benefit the crop in the same growing season. Every tonne also delivers nitrogen, phosphorus, potassium, magnesium, sulphur, and organic matter that improves soil structure and water infiltration on Lambton County's demanding clay profiles.
Why Local Matters
HS Soil Amendments is a one-person operation run by Harm Spangenberg right here in southwestern Ontario. Harm knows Lambton County farmland — the clay-heavy soils around Petrolia, the drainage challenges near Brigden, and the tight planting windows that come with farming this close to Lake Huron. When you call, you get Harm. Not a switchboard, not an order desk.
Call Harm, tell him your acreage and what your soil tests show, and he'll give you a quote and coordinate delivery to your field. That's it.
Don't Let Another Season Slip By
Every season you run without correcting your pH, you're paying for fertilizer that's locked up in the soil and unavailable to your crop. Fall application after harvest and spring application before planting are both effective windows — but delivery slots fill on a first-come, first-served basis.
No commitment. No minimum order. Just a straight answer on whether N-Rich makes sense for your fields.

Common Questions from Lambton County Farmers
How is N-Rich different from regular agricultural lime?
Agricultural lime corrects soil pH — and that's all it does. It also takes 6–8 months to see meaningful results. N-Rich® delivers 23% lime equivalency (CaCO₃) that starts working in 2–4 weeks, plus nitrogen, phosphorus, potassium, magnesium, sulphur, and organic matter. It's a CFIA-approved soil amendment that replaces multiple products with one application.
What application rate do you recommend for Lambton County soils?
Application rates average 1.5 tonnes per acre, depending on your soil test results, current pH, crop rotation, and nutrient needs. Harm will review your situation and recommend a rate that makes sense for your fields — no generic rate cards.
Do I need special equipment to apply N-Rich?
No. N-Rich® is applied with standard manure spreading equipment. Your custom applicator can handle it with the gear they already have — no specialty spreaders or modifications required.
Can I apply N-Rich in the fall after harvest?
Yes. Fall application after harvest is one of the most popular timing windows. It gives the lime and organic matter time to integrate into the soil profile over winter, so your fields are ready to go in spring. Spring application before planting also works well — the fast-acting lime means you'll see pH correction within the same growing season.
How do I know if my soil pH needs correcting?
A soil test is the best starting point. If your pH is below 6.0, you're leaving yield on the table — nutrients you've already paid for are locked up in the soil and unavailable to your crop. Even soils in the 6.0–6.5 range can benefit from lime application to reach optimal levels for corn and soybeans. If you don't have a recent soil test, Harm can point you in the right direction.
