Farmers face a balancing act when deciding how much fertilizer to apply. Applying too much wastes money and adds to nutrient runoff problems. Applying too little reduces yields.
(PhysOrg.com) -- Experiments prompted by a 2008 surprise from NASA's Phoenix Mars Lander suggest that soil examined by NASA's Viking Mars landers in 1976 may have contained carbon-based chemical building blocks of life.
(Phys.org)—Move forward. High-five your neighbor. Turn around. Repeat.
Fungi found in plants may not be the answer to mitigating climate change by storing additional carbon in soils as some previously thought, according to an international team of plant biologists.
As food security becomes an increasingly important global issue, scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation.
Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found.
(Phys.org) -- Soil is the most species-rich microbial ecosystem in the world. From this incredible diversity, plants specifically choose certain species, give them access to the root and so host a unique, carefully selected ...
Earthworms are a welcomed sight in many gardens and yards since they can improve soil structure and mixing. But they are hard to find in the drier soils of eastern Colorado where water and organic matter is limited. Adding ...
Organic farmers use cover crops and organic fertilizers, compost and other amendments to add nutrients to their soil. But are they getting the best bang for their buck?
Food and biofuel crops could be grown and maintained in many places where it wasn't previously possible, such as deserts, landfills and former mining sites, thanks to an inexpensive, non-chemical soil additive.
