The sites included in the meta-analysis compared the effects of changes in long-term fire frequencies on C and nutrients in the upper soil layer (0–20 cm depth); the average treatment length was ...

Chemical fertilizers, which replace three or four nutrients, are simply not enough to replace the complex system that is soil. They're "not a full health package," says Glover.

The UD Agroecology Lab works at the intersection of ecosystem ecology/biogeochemistry and agronomy to research sustainable nutrient cycling. We investigate how diversified cropping systems, ...

2) They kill prey and leave carcasses in specific spots. 3) Carcasses are eaten by carnivores, and decomposition starts. 4) Nutrients from the carcass move into the soil, which boosts nitrogen levels.

An integrated soil fertility management aims at maximizing the efficiency of the agronomic use of nutrients and improving crop productivity. This can be achieved through the use of grain legumes, ...
