FOREWORD .The theme of the XII InternationalForum on Soil Taxonomy andAgrotechnology Transferis very pertinent to Pakistan, being an agriculturalcountry. To make the-country self reliant in food, feed and fibre, increasein agriculturalproductionis a must. This increase could be achieved by provid ing scientific basis to agriculture through researchand through the transfer of agrotechnology to the end users i.e. the farmers. Soil is a non-renewablenatural resource which should be judiciouslyused.In the recentpast, great advances have been made in the field ofsoil science and technology-in the world includingPakis tan. The Soil Survey of Pakistan has collected sufficient basic soils datawhile other researchorganiza tions have carried out research on agronomicandother aspects of agriculturalproduction.Integration of these efforts would definitely be of great benefit. Characterizationof Pakistanisoils according to Soil Taxonomy, as practised by many developed and developing countries, would enable us to take advantage of the research work carriedout in other countries on similarsoils underidentical environ mental conditions. The Forum was arrangedto impart trainingin thisfield to well drawn participants from all over the country andI hope it has achieved its objective. Contributions made to the Forum through technicalpapersand lectures as compiled in this publicationare commendable. The informationprovided is of immense value to the agriculturalplan ners, researchscientists and those responsiblefor agriculturaldevelopment. They are sure to benefit from it. Assistance and cooperation of the Soil Management Support Services (SMSS) of USDA for holding this Forum in Pakistanare thankfully acknowledged. The efforts of the Soil Survey ofPakis tan and the PakistanAgriculturalResearch Council are also appreciated.

The XII InternationalForum was basically a training workshop. It had been organized to create amongst the country-s agriculturalscientists an awareness of the soil-as a vital variablein the plant production enterprise, to familiarize them with the iechnical language internationallyused by pedologists and to highlight its usefulness in facilitatiigagrotechnologytransfer.Because of the very nature of the workshop, it could accomodateonly a limited numberofparticipants.The otherswould, hopgfully, be able to benefit from this compilation of the Forum proceedings. To them it is mainly addressed. This publication is divided into two volumes to separatelycover the two different aspects of the Forum activities, The first volume comprises the indoorproceedings;it contains paperspresented in the technical sessions. Detailedprofile descriptions, analytical,data,prediction of soil behaviour basedon data interpretation,andreports ofon-site discussions,in respect of the soils examined during field trips make.up the second volume. It alsb includes introductionto some of the basic concepts and categoriesqf Soil Taxonomy- the soil classificationsystem practisedin Pakistan. Most -ofthe write-ups especially those constitutingvolume one have been subject to a limited. degree of editorialmodification in consultation with the concerned authors, wherever necessary. or possible.The prime reasonfor effecting these changeswas the endeavourof the Publication Committee to relate, as for as possible, the presented materialto the conditionsprevalentin Pakistan:Creditfor pedon descriptions, and related analyticaldata, interpretedinformationand photographs ofprofiles andlandscapesgoes largely to the SMS S: . Preparationof this publication owes much to the kind patronizationand inspiringguidance of Dr. M. Bashir Choudhri, Director General, SSP. bn bealf of the Committee,, it is my privilege to convey ourdeepsense of gratitude to him. It is also ourpleasureto put on.recordour appreciationof the cooperation extended to'us by the various authors.The services of our colleagues in the SSPfor the typing, cartographic andproof readingwork are gratefully acknowledged. Personally,l am much obliged to members of the Publication Committee especially the Secretary, for their whole hearted supportand untiring-effortsduringall phases of the work.
