High Soil Potassium Levels Do Not Increase Leaf Potassium Concentration in Rabbiteye or Southern Highbush Blueberry
In the coastal plains of Georgia, soils are sandy with low pH, low cation exchange capacity (CEC), and a high rate of K leaching. To manage crop nutrition effectively and preserve soil physicochemical properties, it is essential to adjust fertilizer applications to the physiological demands of the…

Evaluating Sap Analysis as a Tool to Assess Nutrient Status in Blueberries
Sap analysis is a rapid method for assessing plant nutritional status, identifying deficiencies, and improving management practices to enhance productivity. However, blueberry producers lack research-based guidelines for leaf sample collection methodology and nutrient interpretation. In this study…

Influence of Soil Horizon Depth and Sulfur Availability on Rooting and Flavor of Sweet Onions Under Variable Moisture Conditions
Sulfur (S) availability in the soil is closely associated with onion pungency and previous research has identified S accumulation in the soils of the Vidalia onion (Allium cepa) region, particularly in the subsurface claypans (Bt horizons) as a potential factor that could significantly affect S…

Efficacy and Economics of Different Soil Sampling Grid Sizes for Site-Specific Nutrient Management in Southeastern USA
Precision soil sampling on larger grid sizes (≥2.0 ha) is a common practice to reduce the number of soil samples and associated sampling costs. A study was conducted to evaluate the influence of different grid sizes on the depiction of spatial nutrient variability and their influence on the…

Evaluation of sap extraction methods for nutrient diagnostics in lettuce, cucumber, and tomato in controlled environments
Abstract Controlled Environment Agriculture (CEA) enables the cultivation of high-value crops under controlled environmental conditions, requiring precise nutrient monitoring to optimize fertigation. Standard practices to monitor plant nutrient status include nutrient leaf analysis (NLA), the…
