1. Site-specific Phosphorus And Potassium Fertilization Of Alfalfa: Fertilizer Usage And Sampling Density ComparisonAlfalfa accounts for the largest cropping area in both the High Desert and Intermountain regions in California, and the use of site-specific management (SSM) can potentially improve farmers’ fertilization practices and crop nutritional status. These areas have limited to no studies regarding nutrient SSM, and variable rate (VR) fertilizer application has not been commonly used by farmers in either area. Considerable range of soil nutrient levels have... A. Biscaro, S. Orloff |
2. Quality of Interpolated Maps of Soil Mechanical Resistance to Penetration as Support for Variable Rate Compaction ManagementReliable continuous maps of soil mechanical penetration resistance (SMPR) are essential for site‑specific compaction management, but their usefulness depends on how interpolation methods respond to different spatial dependence patterns along the soil profile. Rather than seeking a single “best” interpolator, this study explicitly addresses how the suitability of interpolation methods varies as a function of the spatial structure of SMPR, an aspect seldom explored in depth in previous...
