Soil carbon (C) distribution, which is deeply correlated with soil extracellular enzyme activity and its temperature sensitivity (Q10), are important for predicting the organic (SOC) pools under climate warming. However, high spatial heterogeneity in tropical forest soils makes predicted results vary significantly. Thus, a total of 87 samples three types, eight slope orientations, four vegetation types were selected from Wuzhishan Hainan Island, China. SOC activities six enzymes, Q10 at 10, 20, 30, 40 °C investigated to supplement data. The showed that: (1) ranged 24.82 87.72 g/kg. primary was significantly higher than that secondary forest, cloud forests hilltop scrub elevations lowland rainforests montane lower elevations. amount recalcitrant lowest.

Abstract The rising population is increasing food demand, yet actual crop production limited by the poor efficiency of classical fertilizers. In particular, only about 40–60% fertilizer nitrogen, 15–20% phosphorus and 50–60% potassium are used plants, rest ending polluting environment. Nanofertilizers promising alternatives. Here, we review plant nutrients, synthesis zinc oxide nanoparticles, encapsulation nanoparticles in fertilizers, effect on plants.

Abstract The rice rhizosphere microbiota is crucial for crop yields and nutrient use efficiency. However, little known about how co‐occurrence patterns, keystone taxa functional gene assemblages relate to soil pH in the soils. Using shotgun metagenome analysis, microbiome was investigated across 28 fields east‐central China. At higher sites, taxonomic network of soils more complex compact, as defined by average degree, graph density complexity. Network stability greatest at medium (6.5 < 7.5), followed high (7.5 pH). Keystone were abundant correlated significantly with key ecosystem functions. Overall genes involved C, N, P S cycling a relative abundance soils, excepting C degradation (e.g. starch, cellulose, chitin lignin degradation). Our results suggest that microbial stable pH, possibly indicating increased efficiency cycling. These observations may indicate routes towards efficient management understanding potential effects acidification on system.
