may reduce crop yields or quality by interfering with the uptake of other nutrients. **
For transplanted tomatoes, peppers and eggplant apply a starter solution high
in phosphorus such as 10‑34‑0 at 1 L/100 L of water or 6‑24‑6
at 1 L/75 L of water at planting. Under high temperatures and on sandy soils,
use half the concentration of fertilizer. ***For transplanted broccoli,
brussels sprouts, cabbage and cauliflower, if no insecticide is used in the planting
water, apply a starter solution high in nitrogen such as 20‑20‑20
at 1 kg/200 L of water. Under high temperatures and in dry sandy soils use half
the concentration of fertilizer but do not reduce the volume of water. †Garden
in brackets. HR, MR, LR, RR, and NR denote, respectively, high, medium,
low, rare and no probabilities of profitable crop response to applied nutrient. Approved:
Ontario Soil Management Research and Services Committee (June 2010)
