Climate-smart agriculture aims amongst others at protecting and increasing soil organic carbon (SOC) stocks. The allocation of metabolised (C) between microbial growth respiration, i.e. C use efficiency (CUE) is crucial for SOC dynamics. We hypothesised that raising pH would alleviate CUE-limiting conditions liming could thus increase CUE, thereby supporting accrual. This study investigated whether CUE can be manipulated by how this might contribute to stock changes. effects on biomass C,...
Agricultural management can influence soil organic carbon (SOC) stocks and thus may contribute to sequestration climate change mitigation. The depth which agricultural practices affect SOC is uncertain. Soil have an important bearing on dynamics, so it consider effects capture fully changes in stocks. This applies particular the evaluation of farming measures, are becoming increasingly due change. We sampled analysed upper metre mineral cropland soils from ten long-term experiments (LTEs)...
Crop production often leads to soil organic carbon (SOC) losses. However, under good management practice it is possible maintain and even re-accumulate SOC. We evaluated how different cropland techniques affected SOC stocks in the topsoil (0–30 cm depth) of 10 long-term experiments (LTE) Germany. found that were particularly enhanced by mineral fertilization amendments like straw incorporation a smaller degree irrigation, but only slightly choice preceding crops. In agreement with global...
Abstract Diverse temperate forest types and a high atmospheric humidity have recently been suggested for the Eocene source area of Baltic amber. However, ferns are astonishingly rare as inclusions in this amber, which is contrast to other seed‐free land plants, fungi, lichens. Moreover, identities some few described putative fern taxa dubious, fossils were even assigned Paleozoic seed genera Alethopteris , Pecopteris form genus Sphenopteris containing Mesozoic fern‐like leaf fossils. Here,...
The allocation of metabolised carbon (C) between soil microbial growth and respiration, i.e. C use efficiency (CUE) is crucial for SOC dynamics. pH was shown to be a major driver CUE in agricultural soils therefore, management practices control pH, such as liming, could serve tool modify physiology. We hypothesised that raising would alleviate CUE-limiting conditions liming thus increase CUE, thereby supporting accrual. This study investigated whether can manipulated by how this might...
With the increase of drought events due to climate change, agricultural production is under pressure maintain yields. The subsoil (> 30 cm) often harbours unexploited water and nutrient resources that can meet needs plants when topsoil has already dried out. fertility soil also closely linked its organic carbon (OC) content. A higher (SOC) content improve structure, which associated with a infiltration rate retention capacity thus facilitate adaptation agriculture changing climate....
