Ilaco handbook

Like its predecessors, this third revised edition of the Agricultural Compendium is packed with a wealth of statistical and general information about almost every aspect of agriculture in the tropics and subtropics. "Anyone in tropical rural development, whether in a technical capacity or as an economist/planner making use of technical results, would both save themselves time and increase their understanding and efficiency through possession of this compendium. It is not only a reference volume but potentially a major contribution to mutual understanding and therefore communication between different disciplines." commented Soil Survey and Land Evaluation after the publication of an earlier edition. Numerous sections (e.g. Chapter 7, Part B - Fisheries) and even complete chapters (e.g. Chapter 3, Geodosy; Chapter 10, Sociology) have been rewritten for the present edition. A number of new sections have also been added (e.g. in Chapter 3, a section on remote sensing techniques). Furthermore, in view of the now common use of scientific pocket calculators and personal computers, a number of graphs have been replaced by the original formulae.

Agricultural Compendium: For Rural Development in the Tropics and Subtropics focuses on the development of rural resources in the tropics and subtropics, as well as climate, water control, and animal production. The book first offers information on climate and soil and land classification. Topics include phenomena relevant to agricultural meteorology, classification of climate, parent materials of soils, soil fertility and description, land evaluation, and systems of soil classification. The text then takes a look at geodesy, as well as aerial photography, instruments and accessories, measuring methods, and calculation of surfaces. The publication elaborates on water control and land improvement, including surface water and groundwater hydrology, drainage, irrigation, land clearing and leveling, reclamation of saline and alkali soils, and soil improvement. The text then examines agriculture, animal production, fisheries, and farm economics. The manuscript is highly recommended for agriculturists and readers interested in the development of rural resources in the tropics and subtropics.

FUNDAMENTALS OF TURFGRASS MANAGEMENT THE PREMIER TURFGRASS MANAGEMENT HANDBOOK—UPDATED AND EXPANDED Fundamentals of Turfgrass Management is the longstanding authority on all aspects of the science and practices behind world-class turfgrass care. This fully revised Fifth Edition comes enriched by two new authors who share their cutting-edge research and real-world expertise on such topics as growth, soil testing, nutrition, herbicides, insecticides, and fungicides. Coverage throughout is refreshed with new illustrations and charts, as well as: Expanded coverage on professional lawn care programs, including cool-season and warm-season turfgrasses, establishing methods and costs, cultivation, sand topdressing, and more Enhanced material on the most up-to-date thinking and practices in weed management Brand-new chapters on the environmental, economic, and quality-of-life benefits of well-maintained turf, as well as the influence of light on turf health Whether you’re earning a degree or a paycheck, Fundamentals of Turfgrass Management, Fifth Edition remains the most complete, respected guidebook of solutions for developing and maintaining the finest-standards of turfgrass.

The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be valued. The worth of these findings cannot be underestimated as the results are useful to those who need to allocate scarce water supplies between competing uses within a catchment. The assumptions underlying the model, the data used and the results and implications drawn are fully detailed in this paper. This model was connected to a hydrological model and used to simulate various scenarios on the water situation facing users in the basin. This model is the forerunner of similar modeling attempts on similar problems in other regions of the Krishna Basin and in the Murray Darling Basin of Australia.

This Encyclopedia of Land Use, Land Cover and Soil Sciences is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Land is one of our most precious assets. It represents space, provides food and shelter, stores and filters water, and it is a base for urban and industrial development, road construction, leisure and many other social activities. Land is, however not unlimited in extent, and even when it is physically available its use is not necessarily free, either because of natural limitations (too cold, too steep, too wet or too dry, etc.) or because of constraints of access or land tenure. This 7-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the fields of Land Use, Land Cover and Soil Sciences and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.
