Effects of Compound Fertilizer Containing Polyhalite on Soil and Maize Growth Under Different Nitrogen Levels

-

 

The use of compound fertilizer enriched with polyhalite can significantly improve soil structure, nutrient availability, and crop performance, especially under varying nitrogen levels. Polyhalite supplies essential secondary nutrients such as calcium, magnesium, potassium, and sulfur, which complement nitrogen to enhance root development and nutrient uptake. In maize cultivation, integrating polyhalite-based fertilizers with optimized nitrogen rates boosts plant height, chlorophyll content, and grain yield while reducing nutrient loss and environmental impact. This balanced nutrient strategy not only supports sustainable soil fertility but also increases maize productivity under both low and high nitrogen conditions.

Sustainable iron recovery from tailings via green reduction technology: from waste to resource

-
  Sustainable iron recovery from tailings via green reduction technology represents a promising pathway to transform mining and metallurgical waste into valuable resources while minimizing environmental footprints. Tailings, often considered as hazardous by-products, contain significant quantities of iron that can be recovered through innovative eco-friendly reduction processes. Unlike conventional methods that rely on high energy input and carbon-intensive agents, green reduction technologies utilize renewable energy, biomass-derived reductants, or hydrogen-based approaches to extract iron efficiently. This strategy not only reduces greenhouse gas emissions but also mitigates the risks of soil and water contamination caused by tailings storage. By converting waste into a resource, the approach contributes to the circular economy, enhances raw material security, and promotes sustainable mining practices. Moreover, large-scale adoption of such technologies could help industries achi...

From Waste to Growth Evaluating Leachate Sludge for Sustainable Plant Cultivation

-
  Transforming waste into a resource, leachate sludge—often a by-product of landfill operations—holds significant potential for sustainable plant cultivation. Rich in organic matter, nutrients, and beneficial microbes, it can enhance soil fertility, improve water retention, and reduce dependence on synthetic fertilizers. Proper treatment and monitoring are essential to minimize heavy metal toxicity, salinity, or pathogen risks, ensuring environmental safety and crop health. By integrating leachate sludge into circular agriculture practices, waste management facilities can contribute to greener landscapes, reduced landfill impacts, and increased agricultural productivity, fostering a closed-loop system that benefits both the environment and society. #FromWasteToGrowth #LeachateSludge #SustainableAgriculture #CircularEconomy #SoilFertility #WasteManagement #GreenFarming #OrganicMatter #SoilHealth #EcoFriendlyCultivation #LandfillByproduct #SustainablePlantGrowth #AgriculturalInnovat...

Effects of Char and Amendments on Soil Properties and Sugar Beet Yield in Sandy Clay Loam Soil

-
  The application of char and soil amendments plays a significant role in enhancing soil properties and boosting crop productivity, particularly in sandy clay loam soils where nutrient retention and water-holding capacity are often limiting factors. Char, being rich in stable carbon, improves soil structure, aeration, and cation exchange capacity, which leads to better nutrient availability and reduced leaching losses. When combined with organic or inorganic amendments, char further enhances soil fertility by increasing organic matter content, improving microbial activity, and balancing soil pH. These improvements collectively support root development, nutrient uptake, and water use efficiency in crops such as sugar beet. Studies have shown that integrating char with amendments not only enhances sugar beet growth but also significantly improves root yield and sugar content by creating a more favorable soil environment. Thus, adopting char and amendment practices in sandy clay loam ...
