Farmers are a critical link to food production, but many others are also needed to keep farms producing at their best.Allan James of Mid Valley Ag has helped farmers for decades, and recently won Certified Crop Advisor of the Year for the Western Region.He said while many changes have been seen with mechanization and fertilization, there are still many more advancements to come.“Changes in the fertility are coming,” James said. “We’re going to see new products. We’re going to see different combinations of products, and the biostimulant type of products are going to be part of that, because they complement fertilizer and fertilizer complements them. We hope to be able to provide the grower with even better crops and less need for fertilizer, by using biostimulants."James works in the Northern San Joaquin Valley, which is a remarkably productive area. San Joaquin County has more than $3 billion in crop value each year, with top crops including almonds, walnuts, cherries, and wine grapes.
