Soil Genesis, Classification Survey and Evaluation
Soil Genesis, Classification Survey and Evaluation
Soil Genesis That Studies The Evolution Of Soils And The Changes Taking Place In Soil Bodies Has Received Increasing Interest And Attention In The Twentieth Century, And This Yet Continues. Despite The Fact That The Indian Soil Scientists Have Made Much Investigation Into The Subject Of Soil Genesis, Classification, Survey And Evaluation, There Are Very Few Books That Provide Ample Instructional Material Relevant To Situation In India. The Present Book Is Primarily Focused On The Study Of Geological Conditions Of India. Briefly Outlining The Fundamental Concepts Of Soil Genesis And Acquainting The Readers With Rich Minerals Present Under The Soil, The Book Provides A Detailed Study Of The Factors And Processes Of Soil Formation, Including Description And Interpretation Of The Soil Profile And Patterns Of Soils Occurring On The Surface Of The Earth. Furthermore, It Lays Down The Purpose And The Historical As Well As Modern Basis Of Classification Of Soils In Different Countries Across The World. It Particularly Provides An In-Depth Study Of Soils Prevalent In The Varied States Of India In Addition To The Assessment Of Productivity Of Bench Mark Soils Of The Country. The Book Also Covers Significant Areas Like Remote Sensing, Soil Survey, Land Use, Land Capability Classification, Land Irrigability Classification, Land Evaluation, Land Use Planning And Cartography. Considerable Authentic Information Has Been Drawn From The Works Of Indian Soil Scientists In These Disciplines Which Has Necessarily Added To The Value Of The Book.Designed As A Textbook, Its Approach To The Subject Is Reader-Friendly. Its Simple Language And Lucid Style Make It Accessible Even To Average Students. It Is Hoped That The Book Will Prove Immensely Useful And Informative To Students And Teachers Of Geology As Well As Soil Surveyors.

Water and Crop Growth
Water and Crop Growth
No crop can be grown without being adequately supplied with the requisite amount of water at the proper time. A thorough knowledge of the hydrological cycle, amount and distribution of rainfall, water resources and irrigation projects in India facilitates efficient utilization of water for crop production. Inadequate supply of water to crops in semi-arid and arid regions adversely affects agricultural production. Properties of water, the mode of its entry into the soil and its absorption by roots of crops are important for irrigation. This necessitates accurate determination of the soil moisture content, the plants and available water which is essential for growth and yield of crops. Its deficiency adversely affects their growth and yield. Irrigation must be extended to unirrigated areas in order to increase the production of food, fibre and fodder for which we must know the source of irrigation water, units and methods of measurement of water, methods of irrigating crop fields, factors affecting the choice of irrigation methods, the degree of the suitability of the available water for irrigating crops and the factors affecting the suitability of water for irrigation. As water is a relatively scarce commodity, we must know whether water of a little inferior quality can be utilized to irrigate crops. In addition, we must be familiar with the precautions which need to be taken in this regard. The accumulation of excess water in the soils of the crop fields affects the growth of crops adversely enough to reduce their yields. Choice of the method of land drainage varies with the variation in the topography of the land. It is also necessary to rectify the causes of waterlogging to bring the waterlogged land back under the plough to increase agricultural production. This necessitates drainage investigation and laying out of the proper drainage system. Water requirement of crops depends on the climate and the crop. More water is required to produce crops in the arid region than in the humid region. Crops like paddy and sugar cane require much larger amount of water than finger millet and pearl millet. The book extensively deals with all these aspects related to soil and crop production and suggests measures to enhance productivity through water conservation and proper management of water resources. It will be highly useful for the students, teachers and researchers working in this field. Besides, agriculturists and general readers will also find it useful and informative.

Manures and Fertilizers
Manures and Fertilizers
Despite The Considerable Progress Made In Enhancing The Capacity Of Soils To Produce Crops Through The Use Of Manures And Fertilizers, There Are Yet A Large Number Of Ignorant Peasants In Many Asian Countries, Including India, Who Have Been Growing Crops Without Applying Adequate Amounts Of Manures And Fertilizers To Their Crop Fields And Consequently Obtaining Considerably Less Yields. It Needs To Be Realized By One And All That Soil, Particularly In The Developing Countries, Has To Be Fertile Enough If Their Ever-Increasing Huge Population Is To Be Adequately Fed And Clothed. Accordingly, Knowledge Of Farmyard Manure, Compost, Fertilizers And Other Agricultural By-Products And Their Applications Is Indispensable.The Present Book Is A Sincere Effort In Disseminating Information On Manures And Fertilizers. Primarily Designed As A Textbook, Its Wide Coverage Includes Varied Manures And Their Preparation And Effects; And Production And Consumption Of Various Fertilizers Along With The Detailed Elucidation Of Their Properties, Uses, Advantages And Disadvantages. Application Of Both Manures And Fertilizers Separately And In Combination Has Been Explained In Depth In Reference To Individual Crops Of Extensive Variety. It Analyses The Applied Aspects Of Fertilizers And Manures In Their Entirety And Suggests How To Adjust Them To Particular Soil And Particular Style Of Farming. The Book Is Well Supplemented With References And Indexes Which Will Prove Useful Study-Aids To Readers. Owing To Its Reader-Friendly Approach To The Subject, Simple Language And Lucid Style, The Book Is Accessible Even To Average Readers. While It Ideally Caters To The Academic Needs Of Undergraduate And Postgraduate Students Of Agriculture Science, It Is A Lasting Valuable Reference Source For Researchers And Teachers, Peasants, Geologists And Soil Surveyors.
