This book was released on 2021-06-28 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lack of accurate information about soil nutrient requirements coupled with limited access to appropriate fertilizers could lead to mismatch between soil nutrient requirements and fertilizer applications. Such anomalies and mismatches are likely to have important implications for agricultural productivity. In this paper we use experimental (spectral soil analysis) data from Ethiopia to examine farmers’ response to soil nutrient deficiencies and its implications for yield responses. We find that farmers’ response to macronutrient (nitrogen and phosphorus) deficiencies is not always consistent with agronomic recommendations. For instance, we find that farmers in our sample are applying nitrogen fertilizers to soils lacking phosphorus, potentially due to lack of information on soil nutrient deficiencies or lack of access to appropriate fertilizers in rural markets. On the other hand, farmers respond to perceivably poor-quality soils and acidic soils by applying higher amount of nitrogen and phosphorus fertilizers per unit of land. We further show that such mismatches between fertilizer applications and soil macronutrient requirements are potentially yield-reducing. Those farmers matching their soil nutrient requirements and fertilizer application are likely to enjoy additional yield gains and the vice versa. Marginal yield responses associated with nitrogen (phosphorus) application increases with soil nitrogen (phosphorus) deficiency. Similarly, we find that farmers’ response to acidic soils is not yield-enhancing. These findings suggest that such mismatches may explain heterogeneities in marginal returns to chemical fertilizers and the observed low adoption rates of chemical fertilizers in sub-Saharan Africa. As such, these findings have important implications for improving input management practices and fertilizer diffusion strategies.

Book excerpt: Sustainable livelihood security of resource poor farmers is the top priority for the nation today. However, there is wide gap in productivity of various horticultural commodities among different eco-regions, where horticulture can play significant role particularly in arid and semi arid regions, it is far below than the potential productivity. Hence, sustained and steady growth in rural income is critical for positive impact on living standard of various stakeholders. Therefore, an appropriate strategy needs to be devised for such climatically vulnerable regions. The net income of farmers can surely be increased by efficient management of nutrient, water and agri-input, integrated horticulture based farming system, better market price realization, post harvest management and value addition, integration of secondary enterprises and thereby improving productivity of arid and semi-arid horticultural crops. In this book, several such interventions are given in the form of various chapters which will be of immense use improving the productivity and profitability of horticultural commodities.

Download or read book Agriculture and Phosphorus Management written by Andrew N. Sharpley and published by CRC Press. This book was released on 1999-12-20 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the Chesapeake Bay as a case study, Agriculture and Phosphorus Management discusses the impact and management of phosphorus in watersheds. Although urban and other sources contribute phosphorus to the Bay, the papers presented focus on how its role in agriculture impacts water quality. They review the new guidelines and legislation slated for implementation by 2002 directed towards sustainable nutrient management and strategies for implementing them. Phosphorus, an essential element for plant and animal growth, has long been recognized as necessary to eliminate deficiencies and to maintain profitable crop and livestock production. It can increase the biological productivity of surface waters by accelerating eutrophication. Human activities accelerate the rate of eutrophication - principally by increasing the rate at which phosphorus enters the aquatic system. Written by experts from a range of disciplines Agriculture and Phosphorus Management provides a deeper understanding of the diverse, dynamic, and complex factors controlling the impact of agricultural phosphorus management on production and water quality. Each contributor addresses the questions: what do we know, what do we still need to know, where are the major gaps in our knowledge, and how does the information relate to phosphorus management strategies in the Bay Watershed, and other watersheds? As a result this series of papers provides a unique collection of information of regional, national, and international significance and gives prioritized phosphorus management options for not only the Chesapeake Bay Watershed, but for watersheds around the world.

Book excerpt: In order to feed 9 billion people by 2050, sustainable agricultural growth in needed, supporting an agricultural sector which produces enough food, which is inclusive and resilient, and which makes optimal use of innovation and digital solutions. Smallholder and family farmers must play a key role in achieving this. About 80% of the world’s food supply is produced by small-scale and family farmers, yet their full production potential is hardly reached. To strengthen resilience and productivity of these smallholder farmers, they need an enabling environment that supports their access to critical resources such as finance, markets, inputs, information and technical solutions. This issue of ICT Update uncovers the power of organised smallholder farmers. Through a series of case studies, we explore how farmers’ organisations can make use of farmer data to enable access to resources, thereby strengthening the resilience, voice, or livelihoods of smallholder farmers.
