Global mean nitrogen recovery efficiency in croplands can be enhanced by optimal nutrient, crop and soil management practices

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Сен. 16, 2023

An increase in nitrogen (N) recovery efficiency, also denoted as N use efficiency (NUEr), is crucial to reconcile food production and environmental health. This study assessed the effects of nutrient, crop soil management on NUEr accounting for its dependency site conditions, including mean annual temperature precipitation, organic carbon, clay pH, by meta-regression models using 2436 pairs observations from 407 primary studies. Nutrient increased 3.6-11%, 4.4-8%, while reduction tillage had no significant impact. Site conditions strongly affected induced changes NUEr, highlighting their relevance site-specific practices. Data driven showed that global can 30%, current average 48% 78%, optimal combinations nutrient (27%), (6.6%) (0.6%) management. will most cases allow with acceptable losses water. The predicted was below high-income regions but above middle-income regions.

Factors such as extreme temperatures, light radiation, and nutritional condition influence the physiological, biochemical, molecular processes associated with fruit development its quality. Besides abiotic stresses, biotic constraints can also affect growth Moreover, there be interactions between stressful conditions. However, it is challenging to predict generalize risks of climate change scenarios on seasonal patterns growth, development, yield, quality species because their responses are often highly complex involve changes at multiple levels. Advancements in genetic editing technologies hold great potential for agricultural sector, particularly enhancing crop traits. These improvements tailored meet consumer preferences, which crucial commercial success. Canopy management innovative training systems key factors that contribute maximizing yield efficiency improving quality, essential competitiveness orchards. creation habitats support pollinators a critical aspect sustainable agriculture, they play significant role production many crops, including fruits. Incorporating these strategies allows growers adapt changing conditions, increasingly important stability food production.

Optimizing the Nitrogen Use Efficiency in Vegetable Crops

Nitrogen, Год журнала: 2024, Номер 5(1), С. 106 - 143

Nitrogen (N) is the most limiting nutrient for production of vegetable crops, but anthropogenic sources pose risks due to its transformation into several reactive forms and movement throughout environment. The bulk N research date improve Use Efficiency (NUE) has followed a reductionist factorial approach focused on synthetic application rates crop growth response, under monocultures. increased adoption diversified cropping systems, organic sources, alternative management practices makes it more challenging unravel form transformation, movement, uptake dynamics, in time space. Here, based selected review recent literature, we propose holistic highlight key variables as well multilevel system, genetic, environmental, ecological, socioeconomic interactions cycle NUE. best strategies NUE include both inorganic rate calibration studies, germplasm selection, rotations, identification x interactions, pest water management.

Increasing pesticide diversity impairs soil microbial functions

Proceedings of the National Academy of Sciences, Год журнала: 2025, Номер 122(2)

Опубликована: Янв. 9, 2025

Pesticide application is essential for stabilizing agricultural production. However, the effects of increasing pesticide diversity on soil microbial functions remain unclear, particularly under varying nitrogen (N) fertilizer management practices. In this study, we investigated stochasticity microbes and multitrophic networks through amplicon sequencing, assessed community related to carbon (C), N, phosphorus (P), sulfur (S) cycling, characterized dominant bacterial life history strategies via metagenomics along a gradient two N addition levels. Our findings show that higher enriches abundance specialists opportunists capable degrading or resisting pesticides, reducing proportion generalists in absence addition. These shifts can complicate networks. Under increased diversity, selective pressure may drive bacteria streamline their average genome size conserve energy while enhancing C, P, S metabolic capacities, thus accelerating nutrient loss. comparison, was found reduce niche differentiation at mitigating impacts network complexity functional traits associated with ultimately alleviating results reveal contrasting different input scenarios emphasize strategic mitigate ecological use systems.

Soil N₂O emissions from specialty crop systems: A global estimation and meta‐analysis

Global Change Biology, Год журнала: 2024, Номер 30(3)

Опубликована: Март 1, 2024

Abstract Nitrous oxide (N 2 O) exacerbates the greenhouse effect and thus global warming. Agricultural management practices, especially use of nitrogen (N) fertilizers irrigation, increase soil N O emissions. As a vital sector agriculture, specialty crop systems usually require intensive input management. However, emissions from have not been comprehensively evaluated. Here, we synthesized 1137 observations 114 published studies, conducted meta‐analysis to evaluate effects agricultural environmental factors on emissions, estimated systems. The emission soils was 1.5 Tg O‐N year −1 , ranging 0.5 4.5 . Globally, exponentially increased with fertilizer rates. size generally mean annual temperature, precipitation, organic carbon concentration but decreased pH. Global climate change will further intensify Drip fertigation, reduced tillage can be used as essential strategies reduce yields. Deficit irrigation non‐legume cover may also lower Biochar relatively limited reducing effective in increasing Our study points toward that substantial potential for soils.
