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.
The Difference Between Organic Nitrogen Sources: Why equal nitrogen analyses can produce very different crop responses.
.Equal nitrogen analyses do not guarantee equal crop response. Organic nitrogen sources differ in chemical form, dependence on mineralization, accompanying nutrients, and timing of plant availability.
Organic Cucurbits: Matching Nitrogen to Bloom, Fruit Set, and Harvest
A practical guide to organic cucurbit nutrition: match nitrogen availability to vine growth, bloom, fruit set, and harvest to support balanced growth and productive crops.
Growing Organic Carrots: Managing the Root Zone for Marketable Yield
Learn how soil structure, stand establishment, irrigation, nitrogen timing, weeds, nematodes, and root diseases affect marketable organic carrot yield.
Growing Organic Baby Leafy Greens: Why Timing Matters More Than Total Fertility
A practical guide to growing organic baby leafy greens: support uniform emergence, match plant-available nitrogen to crop demand, and coordinate irrigation and early prevention for a productive short season.
Can Available Nitrogen Reduce Alternate Bearing in Avocados?
Can properly timed plant-available nitrogen reduce alternate bearing in ‘Hass’ avocados? This research review examines crop load, nitrogen timing, return bloom, and the unanswered questions surrounding natural ammonia in organic fertility programs.
