Book Description
This publication is structured on the main themes of the consultation: the importance of plant nutrition for meeting agricultural product requirements; soil organic matter, biomass, soil microflora and management of integrated plant nutrition systems; renewable supply of plant nutrients from natural sources and plant nutrient transfer to crops; the place and role of local and external sources of plant nutrients in cropping systems and their evaluation; plant nutrient management in farming systems and in watersheds and territories; and priorities for FAO's Integrated Plant Nutrion Systems (IPNS) programme

Book Description
The main purpose of this study was to determine response of the farmers towards Integrated Plant Nutrition System (IPNS). Ninety respondents were selected following two-stage proportionate random sampling technique. The study also aimed at explaining the assessment of the present status of IPNS at farmers level. The findings indicated that most of the respondents were middle aged (66.7%) had primary level of education (61.1%), had small farm size (60%) and a small family size (51.1%). The respondents had medium extension contact (58.9%) and medium organizational participation (55.6%). It was also found that most of the respondents were early adopters (42.2%) with a medium knowledge on IPNS. The respondents had favorable attitude with medium to high response (68%) towards IPNS. Moreover, education, extension contact, cosmopoliteness, innovativeness and balanced fertilizer use had strong and positive relationship with the knowledge, attitude and skill of the respondents to IPNS. Farmers' extension contact and their innovativeness contributed significantly to develop their favorable response to IPNS. Among the problems shortage of cowdung were more predominant.

Book Description
These papers include two lectures which address the role of Plant Nutrition in the sustainability of agro-ecosystems and the production of enough high quality food to feed the growing world population. Recent advances in Plant Nutrition are reviewed in the 11 papers presented in each of the Symposia devoted to: genetics and molecular biology of Plant Nutrition, nutrient functions, the role of the apoplast in mineral nutrition, plant quality and plant health, salinity and plant-soil-water relations, mineral element toxicity and resistance nutrient acquisition, soil organisms/plant interactions, fertiliser use in relation to optimum yield and environment, nutrient dynamics in natural and agro-ecosystems, and plant nutrition and sustainable development. Current knowledge and research emphasis in these areas of the subject is well illustrated and the reader is provided with a comprehensive view of the state of Plant Nutrition research.

Book Description
This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.
