This book was released on 2020-07-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic farming aims to produce a number of crops, without the use of synthetic chemicals (pesticides) or fertilizers, while enhancing soil composition and promoting biodiversity. This is a traditional, more permanent type of farming that relies on ecosystem services to maintain the integrity of the landscape while still producing sufficient yields. In addition, conventional farming uses pesticides and fertilizers to maximize the yield of a particular crop or set of crops, which are typically genetically modified. This book covers several issues related to the multi-functionality and impacts of organic and conventional farming systems. Chapters cover topics related to organic farming and the economy, farm management, and innovative methods and approaches.

Download or read book Salinisation of Land and Water Resources written by Fereidoun Ghassemi and published by UNSW Press. This book was released on 1995 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-induced salinisation is a major threat to the world's land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world's population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world's irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.

Download or read book Water and Crop Growth written by A.K. Kolay and published by Atlantic Publishers & Dist. This book was released on 2008 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.

This book was released on 2018-07-18 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook has been prepared for the training workshop on innovative methods of amelioration and use of salt-affected soils, which takes place in Kharkiv, Ukraine, in September 2017. This workshop is conducted within the framework of the Implementation Plan of the Eurasian Soil Partnership, which is a sub-regional affiliation of the Global Soil Partnership. The main goals of the Global Soil Partnership (GSP) and Regional Soil Partnerships (RSPs) include the development of global and regional plans of action for the sustainable management and monitoring of limited soil resources as a key element, as well as the maintenance of food security and ecological services of soils. The RSPs rely on the existing regional networks that connect the national and local networks, partners, projects and measures to ensure that the interests of all member countries of the partnership are taken into account. A RSP should give directives for the development of regional targets, priorities and ìrequred mechanisms of implementation and also undertake regular assessments of progress in reaching goals and accomplishing the tasks. The Eurasian Region covers Eastern Europe, Central Asia and Caucasus and includes the following countries: Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkey, Turkmenistan, Ukraine and Uzbekistan. The Eurasian Region is diverse in terms of climatic conditions, soils, flora and fauna, land use and human activities. Soil degradation is a serious problem within this region, with its most destructive consequences including salinization, erosion, loss of soil organic matter, nutrients and biodiversity as well as soil compaction. Soil salinization presents a serious challenge that requires co-ordination between countries that share common water and land resources. International co-operation is also needed to attract and manage investment into water and land resources. It should be emphasized that salinization is both the cause and the result of other agricultural problems. Combating salinization should, together with other measures for achieving the sustainable intensification of agriculture, be considered as a basis for food security..

Download or read book Innovative Saline Agriculture written by J.C. Dagar and published by Springer. This book was released on 2016-08-10 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: The land degradation due to salinity and waterlogging is a global phenomenon, afflicting about one billion hectares within the sovereign borders of at least 75 countries. Besides staring at the food security, it has far reaching and unacceptable socio-economic consequences since a large proportion of this land is inhabited by smallholder farmers. The anthropogenic-environmental changes and the climate change are further adding to the problem of salinity and waterlogging. The phenomenon of sea-level rise will bring more areas under waterlogged salinity due to inundation by sea water. Thus, dealing with the salinity in reality is becoming a highly onerous task owing to its complex nature, uncertainty and differential temporal and spatial impacts. Nevertheless, with the need to provide more food, feed, fuel, fodder and fiber to the expanding population, and non-availability of new productive land, there is a need for productivity enhancement of these lands. In fact, the salt-affected and waterlogged lands cannot be neglected since huge investments have been made throughout the world in the development of irrigation and drainage infrastructure. The social, economic and environmental costs being high for theon-and/off-farm reclamation techniques, saline agriculture including agroforestry inculcated with modern innovative techniques, is now emerging as a potential tool not only for arresting salinity and waterlogging but for other environmental services like mitigate climate change, sequester carbon and biodiversity restoration. This publication attempts to address a wide range of issues, principles and practices related to the salinity involved in rehabilitation of waterlogged saline soils and judicious use of saline waters including sea water. Many of the site specific case studies typical to the saline environment including coastal ecologies sustaining productivity, rendering environmental services, conserving biodiversity and mitigating climate change have been described in detail. Written by leading researchers and experts of their own fields, the book is a must, not only for salinity experts but also for policy makers, environmentalists, students and educationists alike. More importantly, it contributes to reversing the salinity trends and teaches to sustain with salinity ensuring the livelihood of resource-poor farming families leaving in harsh ecologies including coastal areas which are more vulnerable to climate change.
