The project will employ four experimental approaches to compare, with or without pesticides, the impact of three different crop rotation protocols that differ with respect to the diversity gradient of the plants sown. A conventional protocol will include a cash crop. The green manure rotation protocol will include one or two green manure crops amid the main crop. The ecologically intensive protocol will include a number of green manure crops. Green manure crops generate systemic ecobenefits that improve soil health and boost the biodiversity of bio-organisms instrumental to crop health. This greater diversity reduces weed incidence and, consequently, the need for herbicide applications. The results of the four experimental approaches—along with a database of 280 potato crop soil microbiomes, for which the yields and incidence of a number of soil diseases have been measured—will be used to fine-tune a soil microbiome monitoring method. This method and the results of the economic assessment of the protocols studied will serve as decision-making tools for farmers and agronomists.

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.
