CHELATE 10XL combines the benefits of 2 powerful chelating agents, EDTA and Citric Acid, creating the perfect balance to deliver maximum nutrition to the plant. learn more at: www.nulex.com Visit your Nulex Distributor or contact a sales representative at 800-831-4815 were averaged, there was a strong trend toward the Actagro material maintaining the highest level throughout the 1 foot x 1 foot grid for the longest duration. There was a high level of variability in soil pH and P samples, which likely resulted from the short time for lime reaction and the lack of thorough soil mixing with large heavy implements. This variability limited obtaining more significant treatment differences from the apparent trends. In contrast to Dr. Ajwa's work, 10-34-0 performed similarly to the control in most all evaluations (Table 1). Dr. Husein Ajwa is professor at the University of California, Davis; Dr. Charles Krauter is professor at California State University, Fresno; Dr. Jerome Pier is Division Agronomist for Crop Production Services, Stockton, CA; and Tom Gerecke is Director of Research and Agronomy for Actagro, LLC, Biola, CA. Benefiting environment Improved P availability would allow growers to more closely match application rate to crop requirement to the environment's benefit. Many of the potential benefits of greater P mobility and prolonged P availability revolve around greater P efficiency. This seems a natural fit with reduced tillage and no-till cropping. Surface application or shallow placement of such an efficient P material would see needed P move down into the soil with rainfall or irrigation, not simply be carried off the field adhered to soil particles. Applied beneath the soil surface, greater efficiency P fertilizer maximizes crop response for the pounds applied. Grower benefits: • More P availability/mobility allows flexibility with application timing and methods • Increased P availability improves crop P nutrition for yield and quality • Increased P mobility allows better P nutrition in all reduced tillage situations. • Reduced soil tie-up of P means more of applied fertilizer makes it into the crop.
