Biochar Effects on Weed Management

Biochar incorporation in an agriculture field commonly used for row-crop production (e.g. corn, cotton, peanut, soybean).Biochar can potentially provide better conditions in the soil to increase plant growth. However, research has shown that weed species show minimal changes in germination and emergence patterns with the addition of biochar. Regardless, if biochar is used in the field it is important to monitor for changes in weed populations. This is especially important because biochar can decrease herbicide efficacy.
