Biochar mixed with urea as soil amendment? 


Best insight from top research papers

Biochar mixed with urea can be used as a soil amendment to improve soil properties, nutrient uptake, and crop yield. Blending biochar with urea fertilizer can delay the release of nutrients into the soil, reduce nutrient leaching, and improve nutrient utilization efficiency . Intercalation of urea in biochar increases nitrogen content and alters the organic functional groups in the biochar material . Soil amended with biochar has higher pH, organic carbon content, total nitrogen content, and mineral nitrogen compared to unamended soil . Biochar positively affects microbial-mediated reactions in the soil carbon and nitrogen cycles, enhancing carbon and nitrogen use efficiency and reducing potential losses . Additionally, biochar retains phosphorus and potassium ions in soil microbial biomass and exchange sites, increasing their availability for plant uptake . Overall, biochar mixed with urea can be a beneficial technique for improving soil fertility, nutrient balance, and biological processes in the soil, leading to enhanced crop productivity .

What are the effects of biochar on soil stabilization?4 answersBiochar has been found to have positive effects on soil stabilization. It can be used as a potential replacement for cement in stabilizing soft soils with high organic content. The addition of biochar to dredged marine soils (DMS) improved their engineering properties and influenced their performance, with different types of biochar having different effects. Biochar amendments have also been shown to reduce the bioavailability of heavy metals in co-contaminated soils and improve soil biological properties. In the case of soil contaminated with cadmium (Cd), the addition of biochar at different pyrolysis temperatures resulted in the transformation of Cd fractions from unstable to stable states, thus aiding in the remediation of Cd-contaminated alkaline soil. Additionally, biochar addition has been found to increase soil aggregate stability by reducing the net pressure of soil internal forces, such as electrostatic repulsion and van der Waals attraction.
What is biochar modification?5 answersBiochar modification refers to the process of improving the physicochemical properties and functionality of biochar through various techniques. These techniques include physical modification methods such as steam activation and mechanochemical techniques like ball milling, microwave irradiation, and magnetic modification. Chemical modification involves treating biochar with substances like KOH to enhance its properties. Biochar can also be enriched with minerals or combined with nanocomposites to further enhance its performance. The goal of biochar modification is to overcome the limitations of raw biochar, such as its heterogeneous surface functionality, low porosity, and limited adsorption capacity. Modified biochar has improved surface properties, higher nutrient content, and increased adsorption capacity, making it more suitable for applications in soil remediation, wastewater treatment, electrode material, catalysis, and agriculture.
How biochar combined with compost affects soil nutrient extraction?5 answersBiochar combined with compost has been found to have positive effects on soil nutrient extraction. The addition of biochar and compost increased the availability of macronutrients and micronutrients in the soil, promoting microbial growth and mineralization. The combination of biochar and compost had additive effects on soil properties, increasing microbial activity and nutrient release. Biochar amendment increased soil pH, microbial biomass, and the abundance of fungi, G+ bacteria, and actinobacteria, leading to improved nutrient availability. The addition of both biochar and compost enhanced the complexity of microbial-related networks and improved soil nutrient status. Biochar-based compost amendments improved soil quality and associated bacterial communities, leading to improved nutrient uptake in urban forests. Overall, the combination of biochar and compost can enhance soil nutrient extraction and improve soil fertility.
How biochar affects soil nutrient extraction?4 answersBiochar application has been found to have a significant impact on soil nutrient extraction. It can increase soil pH, electrical conductivity, and the content of soil organic carbon, alkaline hydrolysis nitrogen, available phosphorus, and available potassium. The amount and duration of biochar application directly and indirectly affect soil enzyme activities, such as catalase, urease, sucrase, and phosphatase. Biochar also improves the nutrient retention capacity of soil, reducing leaching and gaseous loss of nitrogen, and increasing phosphorus availability. Additionally, biochar application can effectively retain water in soil and inhibit the leaching of nutrients and dissolved organic carbon. However, the effects of biochar on nutrient extraction can vary depending on factors such as biochar type, application rate, and soil pH. Overall, biochar has the potential to be a valuable amendment for improving soil nutrient content and nutrient use efficiency.
Why biochar combined with compost increases soil organic carbon ?5 answersBiochar combined with compost increases soil organic carbon due to several factors. Firstly, the addition of biochar and compost increases the carbon input into the soil, leading to higher soil organic carbon content. Secondly, biochar and compost amendments enhance soil water holding capacity, which creates favorable conditions for microbial activity and organic matter decomposition, resulting in increased soil organic carbon. Additionally, the combination of biochar and compost can mitigate the high mineralization rate of soil organic matter, reducing the loss of carbon from the soil. Moreover, biochar and compost amendments improve soil physicochemical properties, such as nutrient availability and pH, which promote the accumulation of soil organic carbon. Overall, the synergistic effects of biochar and compost contribute to the increase in soil organic carbon content, making this combination a promising method for soil improvement and carbon sequestration.
Does biochar enriched with urea solution more better than combined with chemical fertilizers?5 answersBiochar enriched with urea solution has been shown to be more effective than combined with chemical fertilizers in enhancing nutrient release and crop performance. Studies have demonstrated that blending biochar with urea fertilizer prolongs the duration of maximum nutrient release, resulting in improved nutrient utilization efficiency and reduced nutrient leaching. Additionally, the application of urea mixed with biochar has been found to enhance crop performance and increase nitrogen retention in the soil, thereby preventing nitrogen losses. The use of biochar-based fertilizers, especially when activated and enriched with urea, has been shown to increase grain yield, nitrogen-use efficiency, and agronomic efficiency. Furthermore, biochar-based urea has been found to have a lower risk of nitrogen pollution, reducing the potential for nitrate leaching and nitrous oxide emissions. Overall, the combination of biochar and urea offers a promising approach for improving nutrient management and sustainable agriculture practices.
