Fungal community structure and functional genes abundance in Brazilian drylands under desertification processDesertification causes the depletion of soil's natural resources.Degradation alters all ecological processes that occur naturally soil.This degradation is largely due to changes microbial communities present this complex soil-plantatmosphere ecosystem.One main responsible for maintaining biological balance soil fungal communities, which participate numerous processes, such as nutrient cycling, decomposition organic matter, solubilization by acids, transport nutrients water.However, studies report consequences process on access specific functions are scarce, especially Caatinga biome Brazil, one most populous semi-arid region world.The study was conducted area Irauçuba, state Ceará, where nine restoration areas were established prevent overgrazing animals 2002.The aim describe modulation well related nitrogen phosphorus cycles a gradient.Two chapters considered, first showing grazing exclusion effective restoring community.Whilst second shed light genes, reduces N P while could recover.Therefore, we took an important step towards theoretical foundation seeks efficient strategy combating drylands.

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) Germany quantify depth-specific common practices: nitrogen (N) fertilisation, a combination N, phosphorus (P) potassium (K) irrigation, crop rotation with preceding crops (pre-crops), straw incorporation, application farmyard manure (FYM), liming, reduced tillage. In addition, compaction were examined as negative side effect management. Results showed that 19 ± 3 % total found subsoil (30–50 cm) 4 lower (50–100 cm), including all significant topsoil effects, while 79 7 (0–30 cm). Nitrogen NPK fertilisation treatments had greatest (OC) stocks, followed by FYM incorporation. Sampling down 50 cm resulted significantly higher than when considering only. A pre-crops, tillage did not at any increment. Since approximately 20 impact occurs subsoil, we recommend monitoring programs schemes extend their standard sampling SOC.

Abstract Tree species through aboveground biomass and roots are a key factors influencing the quality quantity of soil organic matter. Our study aimed to determine stability matter in Luvisols under influence five different tree species. The areas were located 25 km north Krakow, southern Poland. included - Scots pine ( Pinus sylvestris L.), European larch Larix decidua Mill.), pedunculate oak Quercus robur beech Fagus sylvatica L.) hornbeam Carpinus betulus L.). Forest stands growing same conditions (Luvisols) with similar geological material (loess) grain size selected for study. We evaluated labile heavy fractions (SOM). Additionally, basic physicochemical properties (pH, carbon nitrogen content, base cation content) determined samples. results our showed that soils coniferous characterized by higher content free light fraction (C fLF ) occluded oLF compared deciduous Similar relationships found (N ). Higher C MAF N contents recorded influenced carbon, cations positively correlated fraction. PCA analysis confirmed connection research shows avoiding single-species conifer introducing admixtures species, which increase SOM, is justified forest management. selection suitable will provide greater stand contribute more accumulation soil.

Soil organic carbon (SOC) pools have the potential to attain sustainable agriculture goals under climate change. External and inorganic nutrient inputs considerably affect SOC mineralization pools. Therefore, a laboratory-based, three-factor soil incubation experiment was conducted investigate impact of different exogenous additions on stability SOC. The study investigated effects three fertilizer types (inorganic, organic, combination organic) rates addition (low, medium, high) while considering two temperature levels (15 °C 25 °C). At °C, application at high rate significantly increased (2.84–19.97%) compared applied low rate, while, 15 had no significant impact. Overall, fertilization resulted in an increase total mineralizable (7.87–84.50%), decomposition decreased. priming effect decreased over time, with main observed during initial 14 days. lesser increment activity index simultaneously yielding higher Q10 fertilizer. mixed fertilizers suggested improve stabilization promote agricultural development.
