Summary: Soil nutrient pools and soil nutrient element contents vary between catchments in the low Arctic area of southwest Greenland, likely due to the presence of muskox and grazing-associated processes. This study emphasizes the heterogeneity of Arctic landscapes and the need for ecosystem-specific research.

Summary: This study aimed to evaluate the forage potential of Nopalea cochenillifera variety Doce in yellow latosol under rainfed conditions in the Brazilian savannah, comparing the fertilization with urea and coated urea at different nitrogen levels. The results showed that a nitrogen level of 240 kg/ha provided higher emission of cladodes per plant, and NFC values were higher when urea was used as fertilizer.

Summary: The formation of soil organic carbon is poorly understood, with uncertainties remaining for the contributions of different inputs to the particulate and mineral-associated organic carbon fractions. Rhizodeposition has the highest efficiency in forming MAOC, while root biomass inputs have the highest efficiency in forming POC. Rhizodeposition and roots play opposite but complementary roles in building MAOC and POC fractions.

Summary: The study in Venezuela analyzed lacustrine soils under banana cultivation and found that high yields are associated with high organic carbon content in stable soils, emphasizing the importance of using less recalcitrant organic fertilizers for sustainable management of banana cultivation.

Summary: This study investigates the impacts of land-use change on soil organic carbon (SOC) and nitrogen stocks in North-West Ethiopia. It finds that conversion of natural forest to grazing and cropland leads to significant depletion of C and N stocks. However, eucalyptus plantation shows potential for soil C recovery. The study also highlights the importance of considering the quality of SOM when assessing disturbance impacts on SOC and N stocks.

Summary: Terrestrial soil organic carbon (SOC) dynamics play an important but uncertain role in the global carbon (C) cycle. Current models fail to accurately represent the size, distribution, and flux of SOC. By initializing SOC pools with measurable C fraction data, our study shows more accurate representation of SOC stocks and better prediction of sensitivity to agricultural intensification and warming.

Summary: Different land use and management practices have varying effects on soil aggregates and nutrient stocks. This study focused on the impact of different ages of wolfberry plantations on soil aggregates and associated nutrients. The results showed that the proportion of macro-aggregates increased significantly with the age of the plantations, leading to improved soil aggregate stability. Long-term wolfberry farming enhanced soil structure and increased stocks of SOC and nutrients, especially in macro-aggregates.

Summary: This study quantified the changes in dissolved organic matter (DOM) composition and nutrient forms along a river with different land use and seasonal patterns. The results showed significant spatial and temporal shifts in DOM composition associated with different nutrient forms. These changes indicated contrasting loading and processing potential depending on land use and seasonal patterns.

Summary: This study evaluated the effects of different planting methods in the no-tillage vegetable system on soil organic carbon and nitrogen stocks compared to the conventional tillage system. The results showed that planting black oats and oilseed radish in the no-tillage vegetable system can increase soil organic carbon and nitrogen stocks compared to the conventional tillage system. This suggests that planting cover crops can improve soil quality, increase organic matter content, and enhance carbon and nitrogen stocks.

Summary: This study analyzed a large dataset to examine the effects of straw return amounts on soil nutrients and rice yields. The results showed that straw return amounts significantly improved various soil parameters and overall rice yield. The study also found that the most significant effects were observed in northeast China. Proper application of nitrogen fertilizer and straw-rotting agent further enhanced nitrogen utilization and rice yield.

Summary: In temperate soils in Northern Italy, factors such as land use practices and soil types influence soil quality and SOM dynamics. Agricultural lands with organic material additions showed good soil quality and efficient use of microbial C, while reclaimed peaty soils were prone to degradation due to stress on soil microbial biomass. Conservative management practices in chestnuts reduced soil degradation risk. Evaluating soil parameters recommended by the FAO can help assess sustainable practices and soil quality.

Summary: This study aimed to assess the stability of soil organic matter (SOM) pools by characterizing the grain size fractions from forest litters and topsoils using Rock-Eval (R) thermal analysis. The results showed that microbial activity and interactions between organic matter and mineral matrix are important factors affecting carbon storage and stability in soil.
