Preparing the Farm for a Wet El Niño Winter: What to Do Before the Rain Starts
A wet El Niño winter can increase the risk of saturated soils, nutrient losses, erosion, runoff, and limited field access. Learn practical steps growers can take before, during, and after heavy rain to protect fields and adjust fertility programs.
When Fertilizer Ratios Create Nutrient Surpluses
Fertilizer ratios can create nutrient surpluses when one nutrient is applied to meet crop demand while others are supplied in excess. Learn how surplus nitrogen, phosphorus, and potassium behave in soil—and why nutrient balance matters.
Growing Organic Lettuce: Better Nitrogen Management, Better Yields, Less Waste
Discover why nitrogen availability during the final 30 days before harvest is critical for organic lettuce yield and quality. Learn how soil testing, better fertilizer timing, and supplemental liquid nitrogen can improve nutrient efficiency while reducing unnecessary applications.
Growing Organic Strawberries
Explore the role of ammonium in strawberry nutrition and what research reveals about nitrogen form, crop uptake, and timing. Learn how to coordinate preplant inputs, in-season feeding, irrigation, and field monitoring in an organic strawberry program.
Growing Organic Stone Fruit: Matching Nitrogen Supply to Crop Demand and Tree Vigor
A practical guide to matching nitrogen supply to crop demand and tree vigor in organic peaches, nectarines, plums, and prunes. Includes COFI fertilizer rates and application timing.
Growing Organic Pome Fruit: Balance Nitrogen, Crop Load, and Tree Vigor
Successful organic apple and pear production balances nitrogen availability with crop load and tree vigor. Learn how nutrient timing, soil and tissue testing, and orchard observations support productive trees and fruit quality.
Growing Organic Peppers: Matching Nitrogen to Fruit Set and a Long Harvest
Successful organic pepper production supports plant growth, fruit set, and a long harvest season. Learn how nitrogen availability, irrigation, and crop observations help growers maintain productive plants and fruit quality.
