Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

Journal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

Exploring eco‐evolutionary and temporal patterns of arbuscular mycorrhizal fungal communities colonizing Sorghum bicolor across sites of contrasting land use history and climate

PLANTS, PEOPLE, PLANET, EarlyView.
Sorghum bicolor is a globally important cereal crop with annual yields exceeding 50 million tons across more than 100 countries and can be grown on marginal lands where conventional agriculture is limited. We examined how eight genetically diverse sorghum genotypes shaped arbuscular mycorrhizal fungal (AMF) community assembly across two contrasting ...
