This book was released on 2005 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn producers in Iowa adopt no-tillage (NT), strip-tillage (ST) or chisel plow (CP) and either commercial fertilizer or liquid swine manure produce corn. The rising cost of commercial N fertilizers raises concerns about using alternative and viable sources of N and P for corn production. The objectives of this study were to evaluate 1) the responses of corn to three tillage treatments (NT, ST and CP) and four N rates (0, 84, 168 and 252 kg N ha−1) of liquid either liquid swine manure or commercial fertilizer N and 2) the effects of tillage on soil temperature, compaction, moisture storage and water extraction by corn root system. The study was conducted at the Northeast Research and Demonstration Farm of Iowa State University near Nashua. The soil at the study site is Kenyon (fine loamy, mixed mesic Typic Hapludolls) soil. The experimental design was a randomized complete block with split-plot arrangement in three replications. The tillage treatments were randomly assigned to each replication as main plots and the N rates of either N source as the subplot. Results of the study showed no significant impact of tillage treatments on plant biomass and corn yield. Increasing soil N application increased corn yield and corn stalk NO3-N concentrations for both N sources. At N rates higher than 100 kg N ha−1, corn showed a luxury consumption of N for both N sources. Soil temperature in the ST treatment compared favorably with CP, but showed an overall advantage over NT, which consistently recorded lower soil temperatures and ERI. Soil moisture storage for all tillage treatments at the top 30 cm and 0 to 120 cm were not significantly different for both N sources. Soil water extraction by corn roots did not show significant differences for all tillage treatments and both N sources. Soil penetration resistance measurements for tillage treatments did not show significant differences but increased with soil depth especially in the top 20-cm soil depth and late in the growing season for both N sources.

Download or read book Conservation Agriculture A Sustainable Approach for Soil Health and Food Security written by Somasundaram Jayaraman and published by Springer Nature. This book was released on 2021-08-20 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio–economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro–ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.

This book was released on 2023-10-30 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds pose a major challenge to the sustainability of agricultural production systems, causing significant crop yield, economic and environmental losses. Chemical weed control tactics play a major role in modern weed management, maintaining the productivity of diverse cropping systems, reducing yield losses and facilitating conservation agriculture. However, the over-reliance on chemical weed control has led to shifts in weed communities in agroecosystems which are now becoming dominated by high competitors and herbicide resistance. Thus, weed scientists and practitioners are urged to develop and incorporate innovative and feasible integrated weed management (IWM) systems that can reduce weed infestations and environmental impacts.

Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.
