Nitrogen management remains one of the biggest challenges—and opportunities—for California growers managing permanent crops. In today’s Agronomic Minute, Dylan Rogers, Sales Account Manager for AgroLiquid, shared practical strategies to help growers improve nitrogen efficiency throughout the season while reducing losses.
Rogers emphasized that nitrogen is one of the easiest nutrients to lose, especially through leaching and volatilization. Because of that, growers should be proactive in adjusting application timing and rates. “Pay attention to rain events,” Rogers said, noting that weather plays a major role in nitrogen loss. Applications made ahead of heavy rainfall can quickly move out of the root zone before plants have a chance to uptake the nutrient.
One of the most effective ways to improve nitrogen efficiency is by applying smaller amounts more frequently. Instead of large, single applications, Rogers recommends splitting nitrogen into multiple “shots” throughout the season. This approach helps align nutrient availability with crop demand and minimizes the risk of loss.
Timing within the irrigation cycle also matters. Applying nitrogen toward the end of an irrigation set can help keep nutrients in the active root zone rather than pushing them too deep into the soil profile. Matching nitrogen applications to established demand curves further improves uptake and supports balanced growth.
Rogers also encouraged growers to consider fertilizer sources that offer protection against environmental loss. Some liquid fertilizers include technologies designed to reduce volatilization and leaching, keeping nitrogen available to the plant for longer periods. Using these products can improve return on investment while supporting regulatory and environmental goals.
Liquid fertilizers offer added flexibility for nitrogen management. They can be easily metered through fertigation systems, allowing growers to adjust rates on the fly and respond quickly to weather or crop conditions. By combining smaller, well-timed applications with protected nitrogen sources, growers can maximize efficiency and support consistent performance across permanent crops.
