What is the most reasable alternative to Urea as fertilizer? 


Best insight from top research papers

The most reasonable alternative to urea as a fertilizer is the use of bioinspired nanohybrids, specifically urea-calcium carbonate (CC) nanohybrids. These nanohybrids have been synthesized using an in-situ rapid carbonation method, resulting in cubic plate-like nanoparticles that are stacked together to form a pine cone-like structure . The urea-CC nanohybrids exhibit controlled release properties, retarding the solubility of nitrogen at least 5 times compared to pure urea . This controlled release property makes the nanohybrids more efficient and targeted in delivering nitrogen to plants, improving Nitrogen Use Efficiency (NUE) . Additionally, the use of CC as a component in the nanohybrids provides added advantages of biocompatibility and non-toxicity . Therefore, the urea-CC nanohybrids have the potential to replace conventional fertilizer systems and contribute to sustaining future food security .

What Use of urea in cattle feeding?5 answersUrea is commonly used in cattle feeding as a cost-effective protein precursor. It can replace a portion of the protein in rations, with the amount utilized depending on the digestible energy content of the diet. Rumen microorganisms can convert urea into microbial protein, making it a valuable non-protein nitrogen source for cattle diets. However, excessive urea intake can lead to toxicity, emphasizing the importance of following recommended feeding guidelines. Research has explored novel approaches to enhance urea utilization, such as developing additives with different carbohydrate sources to improve synchronization between nitrogen and carbohydrate availability for ruminal microbiota development. Efforts to simplify urea treatment methods for improving the nutritive value of high fibrous crop residues in cattle feeding have been highlighted, aiming to optimize feed resources for enhanced animal productivity.
Are there evenly efficient alternatives for nitrogen-based fertilizers?5 answersThere are efficient alternatives for nitrogen-based fertilizers. Several studies have highlighted the use of microorganisms for bioremediation and the application of biofertilizers as effective alternatives to minimize the environmental impact of nitrogen fertilizers. Additionally, utilizing readily available resources such as humic acids, acid sulphates, and zeolites can improve nitrogen use efficiency. Other alternative fertilizers, such as microbial inoculants, value-added compost and biochar, acidulated-microbial active products, and formula-modified fertilizers, have been developed to efficiently utilize nutrients and reduce the losses associated with traditional chemical fertilizers. In the context of China, evidence suggests that over-application and inefficient use of nitrogen fertilizer can be addressed by adopting lower rates of nitrogen application based on local recommendations and soil nitrate measurements, resulting in no loss of yield and sometimes small increases. These findings demonstrate that there are viable alternatives to nitrogen-based fertilizers that can improve efficiency and reduce environmental impacts.
What effect does urea have on the growth of peanuts?5 answersUrea has a positive effect on the growth of peanuts. It can reduce the volatilization amount of ammonia by 30-35%. Urea sulfate fertilizer, which contains urea, can promote the growth of peanuts at the seedling stage by 7-12%. Additionally, the use of urea in chemical fertilizer for peanuts can increase the growth rate and yield of peanuts. Nitrogen application with urea at planting time did not increase the yield of uninoculated peanuts, but a split application of urea, applied at planting and 60 days later, increased the yield by 28% over the uninoculated control.
What are the economic effects of UREA fertilizer on corn?2 answersControlled-release urea, particularly polymer-coated urea (PCU), can be an economically viable option for fertilizing corn. In wet years, PCU resulted in higher grain yield compared to traditional urea fertilizers, with comparable net returns at equivalent nitrogen (N) rates. Despite being 30% more expensive, PCU showed similar economic benefits to urea ammonium nitrate (UAN) in terms of net returns. The use of PCU as a controlled-release urea fertilizer can increase the efficiency of N fertilizers and provide economic benefits to farmers in wet years.
What are the current trends in the global market for urea fertilizer?3 answersThe global market for urea fertilizer is experiencing several trends. Firstly, the growing world population and the increasing demand for food are driving the need for increased agricultural production and the effective use of fertilizers. Secondly, market concentration has been found to have an impact on fertilizer prices, with more concentrated markets generally having higher prices. Thirdly, there is a concern about the environmental impact of urea fertilizer production, particularly in terms of greenhouse gas emissions. Finally, there is a need to analyze the dynamics and structure of fertilizer consumption, including factors such as arable land scale and cereal yield. These trends highlight the importance of developing sustainable and efficient practices in the global urea fertilizer market.
What are some of the alternative energy sources that could replace fossil fuels immediatly?4 answersFontes de energia alternativa limpa que poderiam substituir os combustíveis fósseis imediatamente incluem fissão nuclear, fusão, energia solar, hidrelétrica, geotérmica, eólica, bioetanol, biodiesel, biogás e hidrogênio. Essas fontes têm o potencial de reduzir as emissões de gases de efeito estufa, diminuir os níveis de poluição e conservar recursos não renováveis. A energia solar, em particular, é considerada uma das fontes mais importantes e abundantes de energia renovável, com a tecnologia solar fotovoltaica sendo uma opção promissora para gerar eletricidade. Além disso, os lipídios microbianos são promissores como precursores de biocombustíveis, e esforços de pesquisa estão sendo feitos para convertê-los em combustíveis diesel renováveis. A Enapter, uma empresa de tecnologia de energia, também está desenvolvendo geradores de hidrogênio altamente eficientes para substituir os combustíveis fósseis. Essas fontes alternativas de energia oferecem opções sustentáveis e mais limpas para atender à crescente demanda por energia e, ao mesmo tempo, reduzir as consequências negativas da dependência de combustíveis fósseis.
