Abstract:
... Recycling phosphorus (P) from waste is an effective way to alleviate resource and environmental pollution due to excessive phosphate consumption. In order to better understand the feedback of P cycle to waste recycling methods, a P waste feedback model was built and was then used to predict P waste generation, recycling, loss and phosphate consumption in China under several P management scenarios. ...
... Organic wastes, fertilizers, organominerals, and minerals contain nutrients essential to crops and contribute to increase productivity. However their use can also lead to the accumulation of copper and zinc, which changes the distribution of their fractions and enhances the risk of toxicity to plants and the environment, thereby working against the sustainable development goals. However, the effec ...

Abstract:
... Livestock manure is often used as fertilizer in greenhouses, resulting in simultaneous enrichment of heavy metals and antibiotic resistance genes (ARGs) in soils. The soil-plant system is a non-negligible way to spread ARGs; however, the effects of lead (Pb) on the spread of ARGs and their driving factors in the greenhouse soil-plant system remain unclear. In this present study, the occurrence of ...
... Achieving synergy between food security and phosphorus (P) resource sustainability has been a major challenge for sustainable agriculture. However, addressing this challenge by linking region-specific and whole-process P management strategies has not been investigated. In this study, data collected from field experiments throughout China's major agroecological zones were used to explore potential ...

Abstract:
... Reducing the possibility of a potential phosphorus (P) resource crisis and increasing P use efficiency (PUE) by improving P fertilizer management is of paramount importance for truly sustainable agricultural production. However, information on how layered application of phosphate fertilizer at different soil depths affects yield and PUE in winter wheat (Triticum aestivum L.) is limited. Here, a 2- ...

Abstract:
... Balancing water quality and food production is a global challenge due to complex nutrient cycle and previous soil accumulation. This study investigated crop-livestock integration from watershed perspective, while agricultural and environmental benefits of fertilizer and manure application were quantified through numerical experiments at two spatial scales. The optimal ratio of replacing chemical f ...

Abstract:
... Soil amendment products, such as biochar, with both sustained nutrient release and heavy metal retention properties are of great need in agricultural and environmental industries. Herein, we successfully prepared a new biochar material with multinutrient sustained-release characteristics and chromium removal potential derived from distiller grain by wet-process phosphoric acid (WPPA) modification ...
fertilizers, etc ; Coffea canephora; climate; climate change; crop yield; environment; equations; fruiting; irrigation; phenology; rain; risk; temperature; total nitrogen; tree age; Vietnam; Show all 16 Subjects
Abstract:
... A shift towards earlier flowering is a widely noted consequence of climate change for the world's plants. However, whether early flowering changes the way in which plants respond to climate stress, and in turn plant yield, remains largely unexplored. Using 10 years of flowering time and yield observations (Total N = 5580) from 558 robusta coffee (Coffea canephora) farms across Vietnam we used stru ...
... The environmental behavior of arsenic (As) is commonly affected by the biogeochemical processes of iron (Fe) and nitrogen (N). In this study, field experiments were conducted to explore As uptake in rice and As translation and distribution in As-contaminated iron-rich paddy soils after applying different forms of N fertilizers, including urea (CO(NH₂)₂), ammonium bicarbonate (NH₄HCO₃), nitrate of ...

Abstract:
... Goji berry (Lycium barbarum L.) is one of the most pivotal economic crops with an exceptional nutritional value. Based on its high global consumption, understanding the fruit growth patterns and nutrient accumulation at each developmental stage is crucial for the field and production management of high-quality goji berry cultivars. In this study, a fruit growth and development model of goji berry ...
... Sustainable strategies are essential for zinc (Zn) biofortification and cadmium (Cd) reduction in staple food crops. Herein, we evaluated the phytotoxicity of Glyzinc under foliar and root application (FA&RA) in a lab-scale experiment, and then investigated its Zn efficiency and Cd reduction through foliar application on wheat (Triticum aestivum L.) under field conditions. Compared to RA, FA of Gl ...

Abstract:
... Agriculture is a major contributor to nitrate groundwater contamination. Hence, farmers are demanded to reduce the environmental impact but simultaneously must provide sufficient food products. One important building block for this “sustainable intensification” are appropriate cropping strategies. The potential of modified crop rotations was evaluated in a high-yielding environment in Northern Ger ...
... Biochar applied to the soil can contribute to the sustainability of agriculture by promoting ecosystem services. Tea production contributes to addressing hunger and poverty in developing countries. However, little is known about the impact of biochar amendment on ecosystem services in tea plantations. We evaluated ecosystem services from an economic assessment perspective to better understand the ...
... Optimizing irrigation and nitrogen (N) fertilizer applications is essential to ensure crop yields and lower environmental risks under climate change. The DeNitrification-DeComposition (DNDC) model was employed to investigate the impacts of irrigation regime (RF, rainfed; MI, minimum irrigation; CI, critical irrigation; FI, full irrigation) and N fertilizer rate (N60, N90, N120, N150, N180, N210, N ...

Abstract:
... Reasonable irrigation and fertilization practices can not only improve soil quality, but also increase crop yield, and water-fertilizer use efficiency. However, it is still unclear that the micro-irrigation and fertilization mode is conducive to improving the soil comprehensive environment, the mango yield and water-fertilizer use efficiency in the dry-hot region. The effects of regulated deficit ...

... The fertilizer use-efficiencies particularly of nitrogen (N), phosphorus (P), and zinc (Zn) in alkaline soils are often seriously low. The surplus N released from the conventional fertilizers pollutes the environment and causes climate change. Slow or controlled release N fertilizer can improve its use efficiency and decrease its environmental impacts. Previously, we have shown that the ZnO nanopa ...
... Agriculture lands have low fertilizer retention owing to porosity and irrigation, whereas a significant portion of fertilizer is lost through denitrification, volatilization, surface run-off, and leaching, causing losses of nutrients to air and ground/surface water. Urea fertilizer readily enhances the agricultural yield but also deteriorates the quality of fertile soils. To combat such problems, ...
... The excessive application of nitrogen (N) has caused a series of environmental problems. Brown earth (BE) is one of the main soil types in China, and the specific soil‐forming conditions make it high risk of nutrient leaching. Determining the soil fertility of BE and optimal N application rates for main crops’ production is important to reduce nitrogen leaching. Based on China's second national so ...
