This book was released on 2014-05-14 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book "Long Term Effect of Fertilizers and Manure on Nutrient Uptake of Wheat" has written for describing the role of manure & fertilizers in wheat productivity in long term perspective. The manure provides plant nutrient for longer period to crop and improve physical, chemical and biological properties of soil. It uses an old practice in crop production and fertility improvement. If all the manure is recycled through agriculture can help in saving of chemical fertilizers. The nutrient management in crop production is a big task. Therefore, use of renewable organic sources like manure would be essential for sustainable agriculture. This book provides the information about availability of manure & fertilizers and their role in nutrient dynamics in soil.

Download or read book Soil and Fertilizers written by Rattan Lal and published by CRC Press. This book was released on 2020-05-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.
Download or read book Fertilizer Application on Crop Yield written by Jagadish Timsina and published by MDPI. This book was released on 2019-04-02 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer application can increase crop yields and improve global food security, and thus has the potential to eliminate hunger and poverty. However, excessive amounts of fertilizer application can contribute to groundwater pollution, greenhouse gas emissions, eutrophication, deposition and disruptions to natural ecosystems, and soil acidification over time. Small farmers in many countries think inorganic fertilizers are expensive and degrade soils, and thus policymakers want to promote organic instead of inorganic fertilizers. To develop practical fertilizer recommendations for farmers, yield responses to applied fertilizers from inorganic and organic sources, indigenous nutrient supply from soil, and nutrient use efficiency require consideration. There is a lack of sufficient scientific understanding regarding the need and benefit of integrated nutrient management (i.e., judicious use of inorganic and organic sources of nutrients) to meet the nutrient demand of high-yielding crops, increase yields and profits, and reduce soil and environmental degradation. Inadequate knowledge has constrained efforts to develop precision nutrient management recommendations that aim to rationalize input costs, increase yields and profits, and reduce environmental externalities. This Special Issue of the journal provided some evidence of the usefulness of integrated nutrient management to sustain soil resources and supply nutrients to crops grown with major cereal and legume crops in some developing countries.
Download or read book Save Soil by Managing Soil Nutrient Losses Agronomic Practices and Crop Microbial Interaction World Soil Day 2022 written by Arnab Majumdar and published by Frontiers Media SA. This book was released on 2024-02-07 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is not only a fundamental source for all living organisms but also impacts non-living factors (water, air, minerals, etc.) making it an invaluable and finite resource. The importance of soil expands from agronomy through to industrialization, thus, it is crucial to understand the impact of human activity on soil quality. To address several global issues related to pollution, food security, and health, the United Nations promotes the Sustainable Development Goals (SDGs) with targets to ‘save soil’ by minimizing nutrient loss and pollution load from the soil. Due to increasing anthropogenic pollution load, many soil pollution control measures are failing, therefore, new technologies and eco-friendly solutions are needed to balance and restore soil health. Soil-crop interactions are essential considering the crop yield and productivity under different soil statuses. These processes, including nutrient release or soi detoxification, are mediated by soil-inhabiting microbes. In fact, the intrinsic role of soil parameters, including the different classes of soil, control soil microbiota which in turn modulate soil nutrient contents and makes these bioavailable. Different crops, especially cereals, are constantly interacting with these soil microbes, thus the relationship between soil, crops, and microbes is complex.

This book was released on 2024-05-24 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate-smart agriculture, or CSA, is a multidimensional approach to transforming and reshaping agricultural systems to support food security under the new realities of climate change. Global changes in rainfall and temperature patterns threaten agricultural production and increase the vulnerability of people dependent on agriculture for their livelihoods, residing mostly in the world's developing countries. Climate change interrupts food markets and agro-economy, posing population-wide risks to the food supply. Threats can be minimized by increasing the resilience capacity of farmers through improving agricultural practices as well as enhancing flexibility and resource use efficiency in agricultural production systems. In order to develop a sustainable climate-smart agriculture practice, the first step is to assess the impacts of environmental constricts followed by modeling-based approaches. At the same time, an evaluation of current practices in minimizing abiotic stress in field crops is unavoidable. An assessment of the efficacy of newly developed methodologies is also of prime interest. Improvements in yield stability alone cannot generate the desired growth in the agro-economic sector; slow but steady demand for the improved food quality is also high on the priority list. So “Quality with Desired Quantity” will be a prime focus in the coming years in the agriculture sector. Policies that can influence climate-smart agriculture in the future have also been given equal importance.

Download or read book Nutrient Dynamics for Sustainable Crop Production written by Ram Swaroop Meena and published by Springer Nature. This book was released on 2019-09-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.
