Diagnosis of the Nitrogen Status in Crops


Book Description

Providing a link between theoretical and applied aspects of plant nutrition and agriculture, this book introduces new concepts in plant nutrition. It shows how these can be applied in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. In this way economic benefits can be obtained, while at the same time preventing detrimental effects on the environment. The main agricultural crops - grasses, wheat, barley, Durum wheat, maize, sorghum, grain legumes and potatoes - are covered. The book will be an invaluable source for agronomists.




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.




The Climate–Energy–Land Nexus in Indonesia


Book Description

This book extends the framework of the climate-energy-land nexus to elucidate political, economic, social, and institutional factors and causal mechanisms that stringent climate targets bring about, rather than mitigate a disproportional heavy burden on the forest sector in Indonesia. Assessing climate, energy, agricultural, forest, and transmigration policies, and REDD+ and biochar solutions through a multidisciplinary approach, ranging from biological, agricultural, technological, economic, and institutional lenses, the book identifies the political-economic and socio-technical regimes that cause the crosssectoral transfer of responsibility for greenhouse gas emissions to palm-oil-based biofuel, imposing an excess burden on the forest sector and accelerating indirect land-use change. It also proposes possible countermeasures for agricultural and forest sectors, reconfirming that technical applications and integrated policymaking should trigger the socioeconomic changes that will make transformative change happen in Indonesia. As an analysis of the success, or otherwise, of stringent climate targets, policies, and technological and non-technological measures on the reduction of greenhouse gases, this book will be of great interest to students and scholars in the fields of environment & sustainability, Asian studies, energy, environment and agriculture, forestry, and agriculture & environmental sciences. It will also appeal to practitioners and policymakers tackling net-zero emissions and land and forest governance.




Sorghum


Book Description

Sorghum is among the top five cereals and one of the key crops in global food security efforts. Sorghum is a resilient crop under high-stress environments, ensuring productivity and access to food when other crops fail. Scientists see the potential of sorghum as a main staple food in a future challenged by climate change. The contributors provide a comprehensive review of sorghum knowledge. The discussion covers genetic improvements, development of new hybrids, biotechnology, and physiological modifications. Production topics include water and nutrient management, rotations, and pest control. Final end uses, sorghum as a bioenergy crop, markets, and the future of sorghum are presented. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.




Handbook of Reference Methods for Plant Analysis


Book Description

The Handbook of Reference Methods for Plant Analysis is an outstanding resource of plant analysis procedures, outlined in easy-to-follow steps and laboratory-ready for implementation. Plant laboratory preparation methods such as dry ashing and acid and microwave digestion are discussed in detail. Extraction techniques for analysis of readily soluble elements (petiole analysis) and quick test kits for field testing are also presented. This handbook consolidates proven, time tested methods in one convenient source. Plant scientists in production agriculture, forestry, horticulture, environmental sciences, and other related disciplines will find the Handbook a standard laboratory reference. The Handbook was written for the Soil and Plant Analysis Council, Inc., of which the editor is a board member. The council aims to promote uniform soil test and plant analysis methods, use, interpretation, and terminology; and to stimulate research on the calibration and use of soil testing and plant analysis. This reference will help readers reach these important goals in their own research.




Plant Analysis


Book Description

Plant Analysis: An Interpretation Manual 2nd Edition is an easily accessible compilation of data summarising the range of nutrient concentration limits for crops, pastures, vegetables, fruit trees, vines, ornamentals and forest species. This information is valuable in assessing the effectiveness of fertiliser programs and for monitoring longer term changes in crop nutritional status. New to this edition: *Volume and scope of information accessed from the literature has expanded several-fold. Interpretation criteria for 294 species have been compiled in the tables from more than 1872 published papers. *New chapter on nutrient criteria for forest species. *Includes guidelines for collecting, handling and analysing plant material. An entire chapter is devoted to the identification of nutrient deficiency and toxicity symptoms.







Nutritional Disorders of Grain Sorghum


Book Description

Diagnosis of nutritional disorders; Key to symptoms of nutritional disorders; Disorders producing symptoms mainly on lower leaves; Disorders producing symptoms mainly on upper leaves; Disorders producing no specific leaf.




Phosphorus in Action


Book Description

Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.




Soil and Plant Tissue Sampling in California


Book Description

Classic bulletin from 1978 on conducting soil, plant, and water analysis. Detailed instructions for sampling plants, soils, and waters are given, the critical concentrations of nutrients in plant tissues listed, and interpretive guides for soil and water analyses are outlined.
