Spatial Heterogeneity of Soil Nutrients after the Establishment of Caragana intermedia Plantation on Sand Dunes in Alpine Sandy Land of the Tibet Plateau.

PLoS ONE, 2015
The Gonghe Basin region of the Tibet Plateau is severely affected by desertification. Compared with other desertified land, the main features of this region is windy, cold and short growing season, resulting in relatively difficult for vegetation ...

Functional Diversity and Invasive Species Influence Soil Fertility in Experimental Grasslands

Plants, 2020
Ecosystem properties can be positively affected by plant functional diversity and compromised by invasive alien plants. We performed a community assembly study in mesocosms manipulating different functional diversity levels for native grassland plants ...

Spatial variation of soil nutrients and evaluation of cultivated land quality based on field scale

Open Geosciences, 2023
The current cultivated land quality (CLQ) evaluation method fails to consider the determination of soil nutrients, resulting in the low efficiency of soil nutrient message extraction.

Rubber trees demonstrate a clear retranslocation under seasonal drought and cold stresses

Frontiers in Plant Science, 2016
Having been introduced to the northern edge of Asian tropics, the rubber tree (Hevea brasiliensis) has become deciduous in this climate with seasonal drought and cold stresses.

Microorganisms Cycling Soil Nutrients

, 2019
Microorganisms drive nutrient cycles in soil, and without this key activity, many essential elements would not be available to plants. Conversely, without the input of carbon and energy, primarily from photosynthesis by green plants, soil would consist ...

Nitrogen Use Efficiency in Maize over Sixteen Years of Unbalanced Fertilization with Nitrogen and Potassium

Agriculture
Adequate fertilization with nitrogen (N) and potassium (K) is essential to sustain crop productivity and minimize nitrogen losses to the environment. However, the increasing imbalance in fertilizer use in Poland, with low potassium inputs, may impair ...

Interaction of Soil Nutrients and Arsenic (As) in Paddy Soil in a Long-Term Fertility Experiment

, 2022
In this study, we examined the interaction between arsenic (As) and nutrients in paddy soil which received pig manure and chemical fertilizers for 36 years (since 1984).

Soil Microbiology and Nutrient Cycling

, 2010
Soil organisms play a central role in the recycling of nutrients in soils, making them available to plants, transforming some nutrient elements to gaseous forms which can be lost from soil, and other transformations which predispose nutrients to loss. In this chapter we will illustrate these processes in the context of sustainable crop production.

An optimized method for extraction and purification of inorganic phosphate from plant material for oxygen isotope ratio analysis

MethodsX
Compound-specific stable isotope ratio analysis of oxygen isotopes in inorganic phosphate can be used to study biological phosphorus cycling and the transformation processes controlling the fate of phosphorus. However, methods for extraction of inorganic

Distribution of soil nutrients under and outside tree and shrub canopies on a revegetated loessial slope

, 2017
Studies of soil nutrients in revegetated land have often not provided the sampling positions on a scale of individual trees and shrubs, suggesting that nutrients were assumed to not vary substantially at fine scales.
