Project/Experiment Duration: Continued since 2019

Research Innovation Themes: Management of Natural Resources in Marginal Environments

Project/Experiment Team: Dr. Ahmed El-Naggar Dr. Fatma Rekik Dr. Khalil Ammar Mr. Kaleem Ul Hassan Naeem Mr. Amir Muhammad Mustafa

Objectives:

  1. Determine the effect of biochar as a soil amendment on crop productivity in sandy soils.
  2. Determine the impact of biochar on crop responses to salinity and drought stress conditions.
  3. Determine the effect of biochar on soil nutrient availability.
  4. Determine water-holding capacity and water-use efficiency in soils treated with biochar.
