Part 3/7:
Trenched Fertilizer Method: In another section, onions were spaced out similarly while a trench filled with granular organic fertilizer was created in between two rows. The hypothesis was that the onions would benefit from this additional nutrient source as they grew.
Tightly Spaced Without Fertilizer: The final approach involved planting onions very close together, with no fertilizer applied.
The onions were monitored for approximately two months, leading up to the harvest point.
