High capacity of integrated crop-pasture systems to preserve old stable carbon evaluated in a 60-year-old experiment Soil (IF 6.8) Pub Date : 2023-11-21 Maximiliano González Sosa, Carlos A. Sierra, Juan A. Quincke, Walter E. Baethgen, Susan Trumbore, M. Virginia Pravia
Abstract. Integrated crop-pasture rotational systems can store larger amounts of soil organic carbon (SOC) than continuous grain cropping. The aim of this study was to identify if the main determinant for this difference may be the avoidance of old C losses in integrated systems, or the higher rate of new C incorporation associated with higher C input rates. We analyzed the evolution of SOC in two

The QuantiSlakeTest, measuring soil structural stability by dynamic weighing of undisturbed samples immersed in water Soil (IF 6.8) Pub Date : 2023-11-17 Frédéric Marie Vanwindekens, Brieuc François Hardy
Abstract. We evaluated the performance of a new, simple test to evaluate soil structural stability. The QuantiSlakeTest (QST) consists in a quantitative approach of the slake test, a dynamic weighing of a dried structured soil sample once immersed in water. The objective of this work was threefold: we aimed to (i) derive indicators from QST curves to evaluate soil structural stability, (ii) establish

Improving measurements of microbial growth, death, and turnover by accounting for extracellular DNA in soils Soil (IF 6.8) Pub Date : 2023-11-10 Jörg Schnecker, Theresa Böckle, Julia Horak, Victoria Martin, Taru Sandén, Heide Spiegel
Abstract. Microbial respiration, growth and turnover are driving processes in the formation and decomposition of soil organic matter. In contrast to respiration and growth, microbial turnover and death currently lack distinct methods to be determined. Here we propose a new approach to determine microbial death rates and to improve measurements of microbial growth. By combining sequential DNA extraction

Deep learning with a multi-task convolutional neural network to generate a national-scale 3D soil data product: Particle size distribution of the German agricultural soil-landscape Soil (IF 6.8) Pub Date : 2023-11-10 Mareike Ließ, Ali Sakhaee
Abstract. Many soil functions and processes are controlled by the soil particle size distribution. The generated three-dimensional continuous data product, which covers the particle size fractions of sand, silt, and clay in the agricultural soil-landscape of Germany, has a spatial resolution of 100 m and a depth resolution of 1 cm. This product is an important component for predicting the effects of

Spectroscopic assessment of three ecologically distinct organic carbon fractions of mineral soils Soil (IF 6.8) Pub Date : 2023-11-10 Lewis Walden, Farid Sepanta, Raphael Viscarra Rossel
Abstract. Soil carbon (C) is heterogeneous and exists in various forms along a decomposition continuum from labile fast-cycling compounds to more persistent forms of C, which can reside in the soil for centuries to millennia. Methods for soil organic C fractionation aim to account for this complexity by separating soil organic C into distinct groups that exhibit similar turnover. Our aims were to (a)

The Dynamic Effect of Root Exudates on Soil Structure: Aggregate Stability and Packing Soil (IF 6.8) Pub Date : 2023-11-10 Maoz Dor, Itamar Assa, Yael Mishael
Abstract. The importance of soil structure, packing and stability, cannot be overstated as it controls vital processes in the terrestrial environment. Physical, chemical and biological processes altogether affect the dynamics of soil structure with the biological driver being the most complex and least explored. We quantified, developing and applying advanced methods, the effect of mucilage (0.035

Luminescence dating approaches to reconstruct the formation of plaggic anthrosols Soil (IF 6.8) Pub Date : 2023-11-08 Jungyu Choi, Roy van Beek, Elizabeth Chamberlain, Tony Reimann, Harm Smeenge, Annika van Oorschot, Jakob Wallinga
Abstract. Plaggic anthrosols are one of the major features that contributed to the formation of the present-day landscape of northern part of Europe since the Middle Ages, but their formation history is rather poorly understood. The formation of plaggic anthrosols had an impact beyond the arable fields, impacting the entire landscape surrounding the arable fields, mainly through plaggen management
