This farmer-led research project will establish a native truffle agroforestry site in Kingston, NY, addressing the high-cost, high-failure rate associated with importing European truffle cultivation systems. The project focuses on four native North American Tuber species (T. lyonii, T. cumberlandense, T. canaliculatum, and T. canarevulatum) across two host trees (Oak and Hazelnut). The primary objective is to determine the comparative colonization success of these native truffle/host combinations, targeting a minimum 70% colonization rate verified by DNA barcoding. We will use metagenomic soil analysis to identify microbial communities correlating with success and, based on the findings, develop a standardized Native Truffle Cultivation Protocol suitable for Northeast farmers. The two-year plan utilizes a Randomized Complete Block Design (100 trees, 10 groups) with rigorous, university-supported genetic analysis. Results will be shared with regional farmers via an on-farm Field Day, a Farmer Guide detailing establishment costs, and an online course to ensure widespread adoption of a resilient, high-value native crop system.

This project has three specific, measurable, and time-bound (SMART) objectives for the 2-year grant period:

1. Establishment Success & Host Selection: Determine the comparative mycorrhizal colonization success of four native Tuber species (T. cumberlandense, T. canarevulatum, T. canaliculatum, and T. lyonii) across two different host genera (Oak and Hazelnut) at the Kingston, NY pilot site, aiming for a minimum of 70% colonization rate (measured by ITS barcoding) by the end of Year 1.

2. Protocol Development & Soil Ecology: Identify the key microbial communities and soil parameters that correlate with successful truffle establishment (metagenomic analysis) and use this data to develop a standardized Native Truffle Inoculation Protocol suitable for regional application by Northeast farmers by the end of Year 2.

3. Horticultural Assessment & Long-Term Potential: Assess the growth and survival rates of all 100 inoculated and control host trees and establish the baseline indicator of long-term fruiting potential by the end of Year 2. This baseline will be defined by the successful isolation and identification of Tuber mycelial networks in the near-root soil zone, which is a required step before ascocarp (truffle) formation.
