This book covers the use and dynamics of potassium fertilizers in
agriculture. It explores potassium dynamics in soil,
phytoavailability, uptake and translocation in crop plants, impact
of potassium fertilizers on quality of agricultural produce.
Potassium is an essential plant nutrient that has long been
overlooked in agriculture of many developing countries. In most of
the agro-ecosystems of such countries, potassium balance is
negative because its application seldom matches with crop removal.
Agro-technicians lack enough skills and resources to promote the
right source of fertilizer at the right rate, time and place to
facilitate profitable farming. There is a need for farmers to
update their farming practices so as to improve the crop yield and
quality under unfavorable climatic conditions. Correct application
of potassium fertilizers is directly linked with increased crop
yield per unit land area in most of the developing countries.
Therefore this book fills the gap in the information and provide
the readers with latest updates on use of potassium fertilizers.
This book contains latest information relevant for graduate
students, progressive farmers, extension worker, early career
researchers, and policy makers.
Nitrogen Assessment: Pakistan as a Case-Study provides a detailed
overview of issues and challenges related to nitrogen use and
overuse, thus serving as a reference for researchers in Pakistan
and providing important insights for other geographic regions.
Excess and inefficient nitrogen use in crops and livestock sectors
is polluting our rivers, seas, atmosphere, and ecosystems,
contributing to climate change, hampering biodiversity, and
contributing to stratospheric ozone depletion. This book covers the
importance of nitrogen in relation to food security, human health,
and economic stability in South Asia. It also discusses nitrogen
status, sources, sinks, and drivers of nitrogen use in Pakistan,
focusing on current nitrogen measures and policies. Nitrogen
pollution is one of the biggest challenges of 21st Century, and the
international scientific community is beginning to recognize the
significance of nitrogen pollution and to explore how to combat it.
The editors' institution, University of Agriculture, Faisalabad,
partners with South Asia Nitrogen Hub, which includes about 30
organizations from South Asia and UK working on nitrogen
assessment, budgeting, awareness, and policy guidance, as well as
possible measures to reduce nitrogen pollution. Nitrogen
Assessment: Pakistan as a Case-Study provides an important guide to
this work and is written in a way that is accessible to an audience
with a wide range of experience from advanced students to seasoned
researchers.
