Biochar improves maize growth by alleviation of nutrient stress in a moderately acidic low-input Nepalese soil
- Under a Creative Commons license
- Soil limitations (moisture, nutrients, acidity) were manipulated one by one to find out why biochar improved crop growth.
- Biochar addition increased soil pH, plant available P, K and soil moisture retention in this weathered Nepalese soil.
- The biochar effect on plant growth was mainly due to alleviation of nutrient stress.
