摘要

Purpose

Biochar derived from green coconut residues holds promise for enhancing soil quality, facilitating carbon sequestration potassium nutrition. Introducing solid and liquid biofertilizers and an incubation period represents a strategic approach to maximizing biochar utilization efficiency and optimizing crop productivity.

Materials methods

Biochar was produced via slow pyrolysis, ground, sieved, and then blended with either water or organic fertilizers before application to the soil. Young maize plants were cultivated for 45 days. Plant parameters were evaluated, including shoot and root mass and macro and micronutrient concentrations. Plant nutrient uptake was subsequently calculated, and Principal Component Analysis (PCA) was conducted.

Results and discussion

While all biochar treatments enhanced soil pH, cation exchange capacity (CEC), base saturation percentage, and concentrations of P, K, Ca, and Zn, only treatments incorporating pretreated GCB with poultry litter exhibited improved plant growth, with a 52% increase in aboveground biomass and a 113% increase in root biomass. Biochar did not influence nitrogen (N) absorption, yet it enhanced plant K, Na, Cu, and Zn absorption while diminishing Ca and Mg absorption. Phosphate uptake in the shoot was 25% lower in GCB and 50% higher in GCBPL. The supplementation of poultry litter to GCB enhanced plants' absorption of P, Ca, Mg, Mn, Cu, and K while concurrently reducing Na absorption by 25%.

Conclusion

The pretreatment of green coconut biochar with poultry litter enhanced its effectiveness and enabled a high application rate. The Principal Component Analysis was crucial in identifying the soil parameters that most influenced the behavior of maize plants, particularly P concentration.
