Garlic field
2019-2023 • Market gardening

Developing fertilization strategies for organic garlic farming that combine green and farmyard manure, while taking their N and P supply dynamics and soil quality impacts into account

By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.
