Parsnips - Fertility

Fertilizer requirements are the same as for carrots. (See Table 9-55, Parsnip Nitrogen Recommendations, right.) For more details, see the OMAFRA Factsheet, Commercial Parsnip Production in Ontario, Order No. 81-056.

Table 9-55. Parsnip Nitrogen Recommendations

Phosphorus

Test the soil to determine phosphorus requirements. Where the soil test values are 61 mg P per L soil (ppm) or higher, parsnips grown on both mineral and muck soils are unlikely to respond to additional phosphate applications. For soils testing lower than 61 mg P per L soil (ppm), see Table 1-10, Phosphorus Requirements: Vegetables on Mineral Soils, on page 12, or Table 1-11, Phosphorus and Potassium Requirements: Vegetables on Muck Soils, on page 13.

Potassium

Test the soil to determine potassium requirements. Where the soil test values are 181 mg K per L soil (ppm) or higher, parsnips grown on both mineral and muck soils are unlikely to respond to additional potash applications. For soils testing lower than 181 mg K per L soil (ppm), see Table 1-12, Potassium Requirements: Vegetables on Mineral Soils, on page 14, or Table 1-11, Phosphorus and Potassium Requirements: Vegetables on Muck Soils, on page 13.
