Fertilizer potential of biochar and ryegrass productivity in metal-contaminated soil.

ABSTRACT:

Introduction

Response to fertilization with biochar in contaminated soils for forage crops lacks comprehensive understanding. This study delves into the role of biochar in enhancing soil pH and phosphorus (P) and potassium (K) availability for ryegrass (Lolium perenne) in clay and silt loam metal-contaminated soils.

Methods

Two pot experiments were conducted using switchgrass-derived biochar (SGB) and poultry litter-derived biochar (PLB) with varying biochar application rates: one without plants and the other with ryegrass.

Results

Results demonstrated a significant rise in soil pH with increasing biochar rates, particularly notable for the PLB experiment with plants, attributed to PLB's superior buffer capacity. PLB significantly improved ryegrass productivity
