The Phosphorus Cycle01:21

The Phosphorus Cycle

43.4K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Summary

Phosphorus-laden biochar enhances soil phosphorus availability and use efficiency over 70 days. This slow-release fertilizer, especially from 600°C biochar, maintains higher available P levels compared to mineral fertilizers.

Area of Science:

  • Soil Science
  • Environmental Chemistry
  • Agronomy

Background:

  • Biochar is explored for slow-release phosphorus (P) fertilizers to boost soil P use efficiency and reduce P losses.
  • Long-term impacts of P-laden biochars on soil P availability require further investigation.

Purpose of the Study:

  • To evaluate the effects of original and P-laden biochars on soil P availability and fractions.
  • To compare P-laden biochars with conventional mineral P fertilizer (triple superphosphate - TSP).

Main Methods:

  • A 70-day laboratory soil incubation experiment was conducted.
  • Two biochars from maize stalks (pyrolyzed at 350°C and 600°C) were used, some laden with P.
  • Treatments included soil alone, soil + TSP, soil + biochar, soil + TSP + biochar, and soil + P-laden biochar.

Main Results:

  • Original biochars reduced soil available P due to adsorption.
  • P-laden biochars, particularly the 600°C variant, maintained significantly higher soil available P levels than TSP.
  • No significant differences in soil P fractions were observed between mineral P fertilizer and P-laden biochar treatments.

Conclusions:

  • P-laden biochars act as effective P fertilizers, improving soil P availability.
  • The slow-release characteristic of P from biochar and homogeneous P distribution contribute to sustained availability.
  • P-laden biochar offers a promising strategy for enhancing soil P use efficiency.
