Effect of Different Black Pepper Crop Ages on the Availability of Nitrogen, Phosphorus, and Potassium

Black pepper cultivation at different land backgrounds and fertility can affect crop productivity. This study aims to determine soil-plant nutrients for three farms based on ages the correlation of selected physical chemical properties. Samples were collected in Kapit, Bintulu, Sri Aman analyzed Soil nutrient Bintulu (6 months old) has revealed higher soil pH (4.95) with Fe (0.21 g/kg) N (1.33 contents that is caused by burnt earth residue from burning secondary forest. (12 showed greater TOC (3.34%), P (0.0032 g/kg), K (0.10 benefitted a long year proper pre-establishment earlier. Nutrient removal high Fe, Mn, N, K, while due early harvesting before its mature phase, whereby increase accumulation leaves support berries. Correlation role governing availability TOC, P, K. The increasing increases Hence, affected numerous reasons, such as management.
