Efficient Nutrient Management in California Vegetable Production


Book Description

With growers now facing increasingly stringent regulations designed to minimize nutrient losses to the environment, this guide outlines a fresh take on fertilization best practices for the industry. Nutrient management is critical to successful vegetable production. Given the high value and exacting market standards for size, appearance, and postharvest quality for vegetable crops, fertilizer management practices have focused on optimizing production across a wide range of field conditions. While effective in producing good crops, these practices are not necessarily reflective of input costs or environmental protection. Drawing on 25 years of industry experience, the author outlines the principles of nutrient management that are broadly applicable across crops and production regions. Growers, PCAs, and fertilizer industry professionals will find a practical understanding of crop nutrient requirements, soil nutrient availability, the value and limitations of soil and plant nutrient monitoring, and environmental protection in these pages.




The California Nitrogen Assessment


Book Description

Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.




Nutrient Use Efficiency in Plants


Book Description

Nutrient Use Efficiency in Plants: Concepts and Approaches is the ninth volume in the Plant Ecophysiology series. It presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment. NUE is of particular interest as a major target for crop improvement. Improvement of NUE is an essential pre-requisite for expansion of crop production into marginal lands with low nutrient availability but also a way to reduce use of inorganic fertilizer.

Managing Cover Crops Profitably (3rd Ed. )


Book Description

Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Onions and Other Vegetable Alliums


Book Description

This fully revised, expanded and updated edition of the successful text, Onions and Other Vegetable Alliums, relates the production and utilization of these familiar and important vegetable crops to the many aspects of plant science underpinning their production and storage technologies. Chapters cover species and crop types, plant structure, genetics and breeding, physiology of growth and development as well as pests and diseases, production agronomy, storage after harvest and the biochemistry of flavour, storage carbohydrates and colour and how this relates to nutritional and health benefits. From this wide perspective it is possible to see many examples where underlying scientific knowledge illuminates, explains and can improve agronomic practice. The reader will get an insight into how molecular methods are revolutionizing the study of taxonomy, genetics, pathology and physiology and how these methods are being applied in the breeding of improved crops.




Advances in Research on Fertilization Management of Vegetable Crops


Book Description

This book is a review of the recent literature on the key scientific and technical subjects of fertilization management in vegetable crops. In the last decades, research on fertilization management in vegetables was aimed at producing economical yields with reduced fertilizer inputs by the development and implementation of cropping systems, nutrient management approaches and crop varieties. Examples of the interventions in cropping systems included adequate crop rotations, inter-cropping, double cropping, and other strategies for a better soil organic matter management; nutrient management approaches included modelling, Decision Support Systems, crop nutritional status testing and precision agriculture technologies; amelioration of crop varieties has been directed toward higher nutrient/fertilizer use efficiency.




Handbook of Plant Nutrition


Book Description

The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
