PERAN MIKORIZA ARBUSKULA DAN BAKTERI Pseudomonas fluorescens DALAM MENINGKATKAN SERAPAN P DAN PERTUMBUHAN TANAMAN JAGUNG PADA ANDISOL

JTSL (Jurnal Tanah dan Sumberdaya Lahan), 2017
Phosphorus that is absorbed by Al and Fe in Andisols makes it not available to plants. One of efforts to improve P availability in Andisols is application of agent containing phosphate biological solution. P. fluorescens bacteria have ability to dissolve

Nitrogen Form Regulates Aluminum Partitioning and Physiological Responses in Young Highbush Blueberry Plants Grown in Acidic Volcanic Soil

Agronomy
Aluminum (Al) toxicity constrains plant performance in acidic volcanic soils, yet nitrogen (N) fertilization may influence Al availability and plant responses. This study evaluated the effects of N source and rate under contrasting soil liming conditions
