Rapid turnover of organic matter leads to a low efficiency of organic fertilizers applied to
increase and sequester C in soils of the humid tropics. Charcoal was reported to be …

Green roofs recover green spaces in urban areas and benefit the public, farmers, and
wildlife by providing many environmental, ecological, and economic advantages. Green …

The application of biochar (biomass-derived black carbon) to soil has been shown to
improve crop yields, but the reasons for this are often not clearly demonstrated. Here, we …

Soil fertility and leaching losses of nutrients were compared between a Fimic Anthrosol and
a Xanthic Ferralsol from Central Amazônia. The Anthrosol was a relict soil from pre …

The application of biochar is promising for improving the physical, chemical and
hydrological properties of soil. However, there are few studies regarding the influence of …

Leaching is often an important aspect of nutrient cycling in agriculture (Brady and Weil,
2008). It occurs when mobile nutrients in the soil solution are displaced by percolating water …

Two protein hydrolyzate–based fertilizers (PHFs), one from alfalfa (AH) and one from meat
flour (MFH), were studied chemically and biologically. AH and MFH revealed a different …

Nutrient leaching in highly weathered tropical soils often poses a challenge for crop
production. We investigated the effects of applying 20 t ha− 1 biochar (BC) to a Colombian …

Background and aims Biochar additions to tropical soils have been shown to reduce N
leaching and increase N use efficiency. No studies exist verifying reduced N leaching in field …

In this study, a detailed characterization of earthworm low molecular size humic substances
(LMS) was performed and these substances were used to study their effect on the nitrate …
