Download or read book Conceptual Basis Formalisations and Parameterization of the Stics Crop Model written by Nadine Brisson and published by Editions Quae. This book was released on 2009-01-19 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The STICS crop model has been developed since 1996 at INRA in collaboration with other research and technical institutes. The model syntheses, illustrates and concretizes an important part of the French agronomic knowledge as a point of view on the field and cropping systems working. The formalisations of the STICS crop model presented in this book can be considered as references used in the framework of crop sciences. The book arrangement relies on the way the model designs the crop-soil system functioning, each chapter being devoted to a set of important functions such as growth initiation, yield onset, water uptake, transformation of organic matter etc. One chapter deals with the cropping system and long term simulations and the final chapter is about the involvement of the user in terms of option choices and parameterization. If this book is mainly intended for scientists who use the STICS model, it can also be useful for agronomists, crop modellers, students and technicians looking for elementary formalizations of the crop-soil system functioning.

Download or read book Wheel Traffic Effects on Soil Compaction and Corn Production written by Godfrey M. N. Ngunjiri and published by . This book was released on 1994 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study to investigate the effects of tractor wheel traffic on soil compaction and corn production was conducted at the University of Illinois, Urbana, Illinois. Wheel traffic treatments included; traffic on entire plot, TE; traffic on rows, TO; traffic between rows, TB; and no traffic on the plot, NT. All plots were moldboard-plowed in fall and anhydrous ammonia applied in spring before applying wheel traffic treatments. After the wheel traffic treatments, herbicides were applied and incorporated with a disk harrow and a field cultivator before planting. Soil bulk density, moisture content and cone index were determined before and after wheel traffic treatments. Corn plant populations were determined early in the season and again at harvest. Corn plant height and dry matter weight were measured several times during the growing season. Root density distribution was assessed soon after tasseling and yields were measured at harvest. Tractor wheel traffic was observed to increase soil bulk density and cone index to a depth of 30 cm. In 1992, soil bulk density with the TE treatment increased from 1.24 g/cm$sp3$ to 1.51 g/cm$sp3$ in the top 15 cm of the soil and from 1.29 g/cm$sp3$ to 1.54 g/cm$sp3$ between depths of 16 and 30 cm. In 1993, with the same TE treatment, bulk density increased by 0.24 g/cm$sp3$ to 1.55 g/cm$sp3$ and by 0.12 g/cm$sp3$ to 1.54 g/cm$sp3$ at the corresponding soil depths. Soil cone index with the TE treatment in the top 15 cm increased by over 600 kPa to 1090 kPa in 1992 and by nearly 550 kPa to 1100 kPa in 1993. Wheel traffic compaction was observed to inhibit corn growth rate and yield and to increase barren stalk population. Barren stalk population averaged 3710, 2510, 2230 and 2190 plants/ha with the TE, TO, TB and NT treatments, respectively. Corn yields averaged 10 Mg/ha with the TE treatment compared to an average of 12.5 Mg/ha with the other treatments. Wheel traffic did not significantly affect average root density, but it restricted root proliferation. Equations were developed relating corn root density to distance from plant row and to depth.

Available in PDF, EPUB and Kindle. Book excerpt: Harvested Forages deals with the subject of food for domestic animal feeding. Such food is called "forage" and includes things like alfalfa and other plants usually referred to as "hay." Topics include the ways that this forage is produced, how it is harvested, and ways that it should be stored. Other issues that are dealt with include various criteria and measurement procedures for assessing forage nutritive quality, potential health hazards associated with particular plants and plant toxins, and various issues of plant growth, pest control, and soil fertility--among other topics. This book is essential for any institution with a strong program in range sciences, animal sciences, animal feeding and nutrition, and related programs. Synthesizes and summarizes a vast and widely dispersed literature in animal science Serves as a reference for managers of harvested forages as well as all those involved with the forage production industry

Download or read book Principles of Agronomy for Sustainable Agriculture written by Francisco J. Villalobos and published by Springer. This book was released on 2017-01-25 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Download or read book Agricultural Soil Mechanics written by A. J. Koolen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared with forces occurring in soil mechanics problems in civil engineering, the forces that are applied to soil in farming operations generally have a short duration, less than a few seconds, a small loaded area, no more than a few square decimeters, and small intensities, 10 bar being a high value. On the other hand, soil properties vary widely between those of a weak mud and a stone-like dry soil. Tillage and related applications of force to soil are practiced worldwide in farming. Tillage operations are performed on one hectare of land for every three human beings. This means that for the food production for each individual daily, something like one cubic meter of soil is stirred, or about 20 times his body weight. Theoretical knowledge of this most common human activity, which largely determines the surface shape of the fertile part of the earth, is still very limited. In this book the authors have tried to give an outline of the present state of the art. One of the starting points was a course in soil dynamics taught by the authors at the Agricultural University at Wageningen, The Netherlands. We hope to reach interested readers who have no more theoretical knowledge than high school level, as well as readers who want to go beyond the level of a third year university student. For the chapter on wheels and tires we received substantial support from F. G. J. Tijink of the Tillage Laboratory at Wageningen.

Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.
