  • Do decomposed straw and biochar improve soil physical properties?
  • Decomposed straw and biochar also result in strong water absorption, so the saturated water content of the soil significantly (p < 0.05) increases [16, 36]. There was no significant (p < 0.05) difference in the improvement in soil physical properties between decomposed straw and biochar, which may be related to the short indoor incubation time.
  • Does Pam improve hydraulic conductivity?
  • Research by Wang et al. revealed that when PAM is applied in combination with composted straw and biochar, the improvement effect on the saturated hydraulic conductivity and saturated water content of the soil is the greatest for a PAM dosage of 1%. If the concentration is exceeded, the improvement effect on the soil will be reduced.
  • Why is composted straw better than other materials?
  • On the one hand, this may be because the bulk density of composted straw is greater than that of other materials, such that the total amount of nutrients applied to the soil by the same volume of composted straw is greater, and a greater nutrient application amount leads to an increase in the desorption amount.
  • What are the benefits of composting straw & biochar?
  • The composted straw and biochar can increase the activity of soil microorganisms after being applied to the soil, thereby increasing the cementitious organic matter in the soil and promoting the formation of soil aggregates .
