Download or read book Alleviating Soil Fertility Constraints to Increased Crop Production in West Africa written by A. Uzo Mokwunye and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.
Download or read book Bioremediation of Salt Affected Soils An Indian Perspective written by Sanjay Arora and published by Springer. This book was released on 2017-03-31 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume focuses on the characterization, reclamation, bioremediation, and phytoremediation of salt affected soils and waterlogged sodic soils. Innovative technologies in managing marginal salt affected lands merit immediate attention in the light of climate change and its impact on crop productivity and environment. The decision-making process related to reclamation and management of vast areas of salt affected soils encompasses consideration of economic viability, environmental sustainability, and social acceptability of different approaches. The chapters in this book highlight the significant environmental and social impacts of different ameliorative techniques used to manage salt affected soils. Readers will discover new knowledge on the distribution, reactions, changes in bio-chemical properties and microbial ecology of salt affected soils through case studies exploring Indian soils. The contributions presented by experts shed new light on techniques such as the restoration of degraded lands by growing halophyte plant species, diversification of crops and introduction of microbes for remediation of salt infested soils, and the use of fluorescent pseudomonads for enhancing crop yields.

Download or read book Agroecology in Policy and Practice written by Rachel Bezner Kerr and published by Frontiers Media SA. This book was released on 2023-10-13 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past years, there has been steady growth in work relating to agroecology. People-centred, knowledge-intensive and rooted to sustainability, it is now well established that agroecology matches the transformative approach called for by the 2030 Agenda; a transition to sustainable food and agriculture systems that ensures food security and nutrition for all, provides social and economic equity, and conserves biodiversity and the ecosystem services on which agriculture depends. Although not a new concept, agroecology is today gaining interest worldwide among a wide range of actors as an effective answer to climate change and the interrelated challenges facing food systems, finding expression in the practices of food producers, in grassroots social processes for sustainability and the public policies of many countries around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Download or read book Sulphur in Plants written by Y.P. Abrol and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulphur (S) plays a pivotal role in various plant growth and development processes being a constituent of sulphur-containing amino acids, cysteine and methionine, and other metabolites viz., glutathione and phytochelatins, co-factor of enzymes which contribute to stress repair and amelioration of heavy metal toxicity. Besides, a number of S-containing components are biologically active and, thus, a source for use as medicinal value. The basic global issue before the agricultural scientist and world community is to evolve cultivars and develop methodologies for efficient use of inputs to enhance agricultural productivity. This is particularly true of the developing countries which are going to see maximum rise in population with changing food demands and declining availability of land. Amongst the inputs, nutrients play a crucial role. The major requirement is for N, P and K followed by several micro-nutrients. In this context reports of world-wide S deficiency in the agricultural systems are relevant. The reasons are many. Broadly speaking reduction inS emission, use of S-free N, P and K fertilizers and higher biomass production contributed the maximum. Despite the need for sulphur as an essential plant nutrient and the substantial returns expected from its use, very little attention has been given to fill the gap between supply and demand of S.
