Mycorrhizal associations are generally favourable for vascular plants in nutrient-poor conditions. Still, non-mycorrhizal plants are common in high arctic and alpine areas, which are often poor in nitrogen and phosphorus. The relative proportion of mycorrhizal plants has been found to decrease along with increasing altitude, suggesting that the advantage of the mycorrhizal symbiosis may change ...

The zinc (Zn) supply increases the fruit yield of Citrus trees that are grown, especially in the highly weathered soils of the tropics due to the inherently low nutrient availability in the soil solution. Leaf sprays containing micronutrients are commonly applied to orchards, even though the nutrient supply via soil could be of practical value. This study aimed to evaluate the effect of Zn fert...

Soil nutrient balance is affected by management in crops. A poor technique results an imbalance the soil status which could have a long-term negative impact on crop production. The current study was carried out to assess effect of different rates nitrogen (N), phosphorus (P), and potassium (K) maize-wheat cropping system Cambisols Khumaltar, Lalitpur, Nepal during 2019/20 2020/21. experiment in...

Theoretical arguments suggest that increased plant productivity may not only increase consumer densities but also their fluctuations. While increased consumer densities are commonly observed in fertilization experiments, experiments are seldom performed at a spatial and temporal scale where effects on population fluctuations may be observed. In this study we used a natural gradient in soil fert...

More attention has been paid to estimating soil nutrient status, along with a sharp decrease in total farmland acreage, especially in Beijing Municipality. However, traditional site-specific investigation makes it impossible to apply it to large scale monitoring. The objective of this study was to evaluate and classify soil nutrient status using advanced 3S (global positioning system, GPS; remo...

The response of plant species composition, diversity and soil nutrient availability to different canopysizes and age gaps in a Pinus Massoniana plantation were surveyed in Taizishan, Hubei province, central China. The soil chemical properties of 27 gaps and 3 non-gaps were measured and compared. The study objectives were: (a) confirm whether and when nutrient pulses emerged in small gaps; (b) d...

The mixed oak-pine ecosystems in the southern Appalachians are in decline because of a combination of drought and southern pine-beetle infestation. A commonly applied prescription for restoration of these degraded sites has been to fell all vegetation, allow it to dry, and conduct a site-preparation burn. However, there is little information on the midand long-term influences of this prescripti...

To investigate the effects of different nutrient management regimes on the soil chemical, eco-enzymatic stoichiometric and microbial characteristics, soil samples were collected from a 30-year, long-term field experiment with six plots growing rice. The results showed that as integrated fertilization increased, so did the concentrations of soil total or available nutrients and microbial biomass...
