Soil Testing Optional The test lab will provide results, which are defined as the percentage of nitrogen N phosphorus P and potassium K fertilizer needed to correct deficiencies;
These percentages are the three numbers found on most fertilizers bags.
The test will also report the percentage of Calcium (ca) and organic matter (OM) in the soil.
Calcium is considered a vital pumpkin growth requirement as it helps build cell walls of the pumpkin.
Most Ontario area soils naturally contain 3 to 5% OM.
Giant pumpkins like soil beyond this level, approaching 10% or more will allow you to grow a giant without supplemental fertilizers.
The correct pH level of the soil will aid in the plants roots in easier uptake of the proper required growth elements. Pumpkins grow best in pH ranges from 6.8 to 7.2 but can perform well at levels above or below this range. Follow what the
