Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

Food Security Versus Environmental Health: The Nitrogen Dilemma
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

Assessing plant water status: Part 1 – Classical methods
Abstract As a result of the changing climate, water scarcity poses a significant threat to crop and pasture production. Although soil water content can indicate drought, its measurements often provide limited spatial resolution and are weakly correlated with plant water status, producing misleading drought assessments.

ACTUAL EVAPOTRANSPIRATION IN RELATION TO LEAF AREA
The ratio of leaf area to ground area required for maintaining potential evaporation has been studied in a 4-year investigation, and the influence of leaf area index on the water use and the actual water balance is discussed.

Basin-wide actual evapotranspiration estimation using NOAA/AVHRR satellite data
The present study elaborates on the estimation of actual evapotranspiration at watershed scale using mathematical models and remote sensing techniques. A water balance model was updated and used to simulate runoff from a watershed, based on input data of

ABSTRACT Urban expansion has exerted both direct and indirect impacts on natural land and ecosystem services it supports, driven by increasing population and food demand, yet these underlying pathways remain insufficiently distinguished. Here, we quantified the losses of soil conservation services (water erosion regulation and sandstorm prevention) and

ABSTRACT Deep‐rooted plantations are central to dryland ecological restoration, yet their long‐term cultivation drives widespread deep soil desiccation, threatening ecosystem sustainability. While artificial water replenishment is a key deep soil desiccation mitigation strategy, the depth‐dependent positional effect of stored water on eco‐hydrological ...

ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

ABSTRACT Soil organic matter (SOM) is a key indicator of land degradation and soil functioning. It plays an essential role in nutrient cycling, soil structure, and long‐term agroecosystem resilience. The variations of surface cover, soil moisture and soil texture heterogeneity will affect the accuracy of SOM remote sensing mapping. This study developed
