An agronomist's advice for Eduardo's vineyard farm in Bahia

I farm 2 hectares of vineyard in Bahia. This season I'm dealing with rising soil salinity. I've tried what the local suppliers recommended, but results aren't improving. I'm looking for an agronomist or experienced grower who can look at photos, soil-test results and my planting plan, and advise on what to change. A 30-minute call or exchange of messages would be fantastic. I'm happy to share photos and a soil test. I'm using only what I can afford, so low-cost suggestions are best. I'll share how it goes - and what worked - to help others in the community. I never thought I'd be the one asking, and I'm grateful for every bit of support.
