THE ADVANTAGES OF SOLAR TRACKER / AS VANTAGENS DO SISTEMA SOLAR TRACKER

International Journal of Environmental Resilience Research and Science, 2021
Solar tracking systems allow greater efficiency of a photovoltaic system by continuously adjusting its position in relation to the sun, thus increasing the generation of electrical energy. The integration of photovoltaic solar tracking systems in a photovoltaic plant allows the energy needs of users to be met more widely in a smaller area.

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 ...
