Better farmer access to machinery eases crop residue burning in India

by Julie Mollins / November 14, 2017 EL BATAN, Mexico (CIMMYT) — In conjunction with recent state regulations outlawing the use of fire to destroy field crop waste in northwest India, some farmers are benefitting from technological innovations that can help prevent damaging smog levels in the capital Delhi and other areas, according to scientists. Currently, the majority of farmers in northwest India burn leftover …

Biochar could clear the air in more ways than one

Health, economic benefits of capturing agricultural nitric oxide outlined in a study. Date: July 27, 2017, Source: Rice University Summary: Biochar could reduce local air pollution from agriculture by reducing emissions of nitric oxide from soil. Researchers argue that a better understanding of nitric oxide response to biochar will save lives and money, especially on farms near urban areas where agricultural emissions contribute …

Researcher examines biochar use in forests

Reported by: Matthew Weaver Research is underway that could lead to more uses for waste wood, a U.S. Forest Service researcher says. Instead of thinning stands to boost productivity and burning the resulting slashpiles, researchers believe turning it into biochar — a supplement made of charred biological matter — would be better for long-term carbon storage and boosting soil’s nutrient- and …

Stubborn Soils Resist Composting and Biochar Treatments

Biochar Efficacy on Soil Nitrogen Questioned

            “In my view recent research has not been able to demonstrate an affective, valuable role for biochar in agriculture.”—Professor Gilkes. Lou Gold A UWA study has challenged claims that biochar is more effective in minimising nitrogen leaching from soil than traditional clay amendments. The article published by CSIRO Publishing titled “Clay and biochar amendments …

Researchers receive grant to study biochar

By Jace Dostal, jace.dostal@iowastatedaily.com Sep 3, 2015 Researchers at Iowa State have been awarded nearly $2 million for research on the integrated pyrolysis of biochar systems. Biochar is a product used on soils to return nutrients to the soil, which are removed when biomass is harvested for bioenrgy and aid in sequestering carbon that otherwise would be released into the atmosphere …
