Impact of activated charcoal and tannin amendments on microbial biomass and residues in an irrigated sandy soil under arid subtropical conditions
André Sradnick,Mariko Ingold,Johanna Marold,Rajasekaran Murugan,Andreas Buerkert,Rainer Georg Joergensen +5 more
TL;DR: In this article, the effects of manure application combined with charcoal and tannins, added as feed additive or mixed directly, on microbial biomass, microbial residues and soil organic matter were tested in a 2-year field trial on a sandy soil under Omani irrigated subtropical conditions.

Soil microbial properties of subalpine steppe soils at different grazing intensities in the Chinese Altai Mountains.
TL;DR: In this article, the effects of increasing stocking density on plant biomass are well studied, but little is known about its impact on soil microbial properties, except for the metabolic quotient (qCO2; p < 0.05), the examined soil properties remained unaffected by the increasing stocking densities.
Effects of activated charcoal and tannin added to compost and to soil on carbon dioxide, nitrous oxide and ammonia volatilization
Greta Jordan,Martina Predotova,Mariko Ingold,Sven Goenster,Herbert Dietz,Rainer Georg Joergensen,Andreas Buerkert +6 more
TL;DR: In this article, the effects of adding activated charcoal and tannin either to compost in the field or directly to the soil were quantified for 69 d of composting, and the results were verified in a 20-d soil incubation experiment in which C and N emissions from a soil amended with goat manure (equivalent to 135 kg N ha -1 ) and additional amendments of either 3 t activated charcoal ha −1, or 2 t tANNIN extract ha − 1, or the sum of both additives were determined.

Effects of activated charcoal and quebracho tannin amendments on soil properties in irrigated organic vegetable production under arid subtropical conditions
Mariko Ingold,Herbert Dietz,André Sradnick,Rainer Georg Joergensen,Eva Schlecht,Andreas Buerkert +5 more
TL;DR: In this paper, a 2-year field experiment was conducted on a sandy alluvial soil in Northern Oman investigating the effects of the two amendments either by mixing them with goat manure in the soil (MCmix and MTmix) or by applying manure from goats fed 2.5 % charcoal (MCfed) or 3.6 % tannin (MTfed).

Effects of activated charcoal and quebracho tannins added to feed or as soil conditioner on manure quality in organic agriculture
TL;DR: In this paper, a 2-year field experiment was conducted with sweet corn (Zea mays L.) and radish (Raphanus sativus L.) in the Batinah Plain of Oman.
