1. Management Zone Delineation for Subsoiling Using Apparent Electrical Conductivity, Elevation, and Soil MoistureSoil compaction is a primary physical factor limiting agricultural crop development. It mechanically impedes root growth, alters soil water dynamics, and consequently affects plant nutrient uptake. In agricultural systems under mechanization or animal trampling, compacted layers are spatially heterogeneous. This necessitates spatial analysis approaches for more precise management decisions, as average values often prove inadequate for site-specific problem resolution. Consequently,... T. Oliveira , G.

2. Temporal Variations in Leaf Nutrient Concentrations and Photosynthetic Nutrient Use Efficiency in DurianThis study assessed leaf nutrient concentration in durian leaves and evaluated the photosynthetic use efficiency of nitrogen (N), phosphorus (P), and potassium (K) on durian trees over two fruiting seasons. This study also provided nutrient recommendations for durian fertilization using the Diagnosis and Recommendation Integrated System (DRIS) and optimal nutrient management range. A total of 63 mature trees were selected for leaf sampling. All samples were collected at two growth stages in each... M.F. Omar, S.K. Balasundram, N.E. Tajidin |
