One of the challenges is the poor physical and chemical properties of albic soil, which hinders crop growth. Another challenge is the lack of knowledge on the impact of fertilization strategies on albic soil properties and crop yield. The paper also identifies the challenge of optimizing fertilization strategies to improve soil fertility and crop yield.

High viscosity, acidity, and carbon depletion of albic soils pose significant challenges for sustainable crop production. Soil compaction and poor aeration exacerbate drought-flood vulnerability and reduce fertilizer efficiency. The complex interactions between biochar, manure, and soil properties require further investigation.
