Book Description
Agriculture builds upon the integration of crops and the environment, with which its yield depends strongly on a healthy soil foundation. With that in mind, the knowledge of the soil and fertilizer is crucial to maintaining an environment with optimal nutrients, water and oxygen for crop production. Soil is one of human's precious resources, the protection and nurturing of our soil is thus an integral part of sustainable development. Effective soil management is considered not only a technology, but also an art. In practice, to make use the full potential of the land, the management strategies need to take account of the differences and characteristics of the soil, plant and climate that are unique to each geographical location. Such an approach is increasingly more important nowadays because of the increasing loss of cultivable land and need of high quality agricultural products.

Book Description
In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.

Book Description
Nutrient use efficiency is a measure of how efficiently plants use the available mineral nutrients to produce economic produce. Improving nutrient use efficiency is very much essential under current scenario besides an understanding of the nutrient dynamics in soil-plant system."Enhancing nutrient use efficiency: Concepts, methods, and management interventions" is a comprehensive book which has a compilation of topics related to enhancement of nutrient use efficiency of various crops and cropping systems. Although it depends on the ability to plants to take up the nutrients from the soil, management practices have a key role to intervene the use efficiency. This book has 27 chapters written by eminent researchers in the field and addresses multifaceted approaches to enhance the nutrient use efficiency. Improving nutrient use efficiency is a prerequisite to reducing production costs in the wake of escalating cost of agricultural inputs in farming besides minimizing environmental contamination. Soil physical management is the foremost strategy to enhance the nutrient use efficiency. Hand held devices are popular among the farmers for nitrogen management in rice in several parts of the country, besides slow release nitrogenous fertilizers. Experiences from Long term fertilizer experiments and soil test crop response correlation are of immense use to understand the nutrient dynamics in soil and in turn designing practices for higher use efficiency.

Book Description
As soil and crop management procedures have become more complex, County Agricultural Agents, farm advisors, consultants, and fertilizer and chemical dealers have had to specialize in some aspect of soil fertility and crop nutrition management procedures, limiting their ability to provide a range of advice and services. Most farmers and growers can no longer turn to just one source for the information and instruction needed to achieve their production goals. With over 70 percent new material, the second edition of the Plant Nutrition and Soil Fertility Manual discusses the principles determining how plants grow and the elements essential for successful crop production, with a focus on the principles of soil fertility and plant nutrition. The book covers physical and chemical properties of soil, chemical and organic fertilizers, soil acidity and alkalinity, liming and liming materials, and micronutrients essential to plant growth. It also describes elements toxic to plants, soil testing, and plant analysis. The topics and discussion in this self-contained book are practical and user-friendly, yet comprehensive enough to cover material presented in upper-level soil and plant science courses. It allows practitioners with general background knowledge to feel confident applying the principles presented to soil/crop production systems.

Book Description
Most Of The Arable Soils Of Humid Temperate Areas Are Now Employed For Crop Production. With An Ever-Increasing Population, The World Is Again Rapidly Turning To The Further Development Of Irrigation In The Semi-Arid And Arid Lands Which Comprise Over Half Of The Earth S Land Surface. Today More Than Half Of The World S Population Is Dependent On Food Produced Under Irrigation. Authors Have Kept Constantly In Mind The Idea Of Integrated Plants Which Will Give Maximum Production On Irrigated Farms. In This Approach, Discussion Of Such Topics As Soil Water Relations, Salt, Alkali, Soil Physical Properties, Organic Matter, Crop Rotations, Fertilizers, And Irrigation Practice Have Been Directed Toward Recognizing The Solving Practical Farm Problems. The Emphasis On Farm Planning Throughout The Book Has Been Brought To A Final Conclusion With A New Chapter On Planning The Irrigated Farm. The Recent Rapid Expansion Of Irrigation In Humid Regions At First Thought Seems To Justify Special Treatment. But Further Consideration Indicates That The Same Fundamental Principles Are Involved Wherever Irrigation Is Practiced, Whether In Arid Or Humid Areas. The Salt Problem Seldom Occurs In Humid Regions And Liming Must Be Practiced, But Still The Underlying Principles Of Irrigation Agriculture Are The Same. In Preparing The Manuscript The Authors Have Sought To Emphasize Fundamental Principles That Underlie Soil Management Practices. Emphasis Is On Basic Principles Rather Than On Field Practices. The General Approach Is To Present First The Fundamental Principles And Second The Applications Of The Principles In Solving Individual Problems. The Authors Sought To Bring Together Viewpoints From Different Fields Of Investigation And To Harmonize Them Into An Integrated Presentation. For Example, In Soil Moisture Studies, Soil Scientists Have Customarily Dealt In Terms Of Physical Stresses Exerted On Moisture By Capillary Pull And Adsorption By Soil Particles; Plant Physiologists Have Been Concerned With Osmotic Stress Value Resulting From Salts Dissolved In Soil Or Culture Solutions. In Irrigation Agriculture, Both Concepts Are Vitally Important And Are Presented As A Unified Principle That Must Be Evaluated In Estimating The Water Relations Of Plants In Irrigated Soils. This Book Will Be Useful In College Dealing With Irrigation And The Management Of Irrigated Soils, But Also As A Reference Guide To Those Giving Technical Advice To Farmers On The Management Of Irrigated Soils.
