Excerpt from Growing Plants Without Soil for Experimental Use In contrast, our objective has been to produce Vigorous, healthy, uniform plant material in regulated environments for experimental purposes. This publication is intended for those with some knowledge of plants who want to grow one or more species for experimental purposes, for demonstra tions in schools, or for science projects where limited facilities are available. Techniques and equipment are described that are used at the Metabolism and Radiation Research Laboratory, Fargo, N. Dak., to raise crop and weed species in the absence of soil for experiments in which pesti cides and their metabolites are applied to plants or plant parts, often in radioactive form. Some of the techniques have been adapted specifically for use with radioactive tracers, where consideration must be given to the absorptive properties of the containers and their disposability or ease of decontamination.

Excerpt from Experiments With Plants: A First Schoolbook of Science The following chapters are intended not as a botanical lesson book, but as a general introduction to experimental science. General Plan. Attention may be drawn to one or two features of the course. 1. The various subjects have been considered in their relation to the living plant as a centre round which they may be grouped in a natural way. Thus it has been possible to include such topics as the composition of the atmosphere, the importance of water, physical characteristics of the soil, the meaning of chemical union, changes of state and latent heat, the nourishment and reproduction of plants - without, it is hoped, sacrificing continuity of treatment.

Excerpt from The Physical Properties of Soils: A Laboratory Guide There are various ways of expressing the amount of water present in a soil: (1) as per cent of dry weight of the soil, (2) as per cent of wet weight, (3) as pounds per cubic foot, and (4) as surface inches. The water content is usually expressed either as per cent of dry weight or as pounds per cubic foot. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales Covers plant anatomy: an essential component to understanding soil and plant water relations

Various studies have shown time and again that small organic farms and home gardens are capable of producing more food per acre with less fossil energy than large-scale commercial agricultural installations dependent on machines and toxic chemical fertilizers and pesticides. This classic book by Wolf D. Storl, a respected elder in the practice of permaculture, details how food is grown holistically and beautifully by traditional communities around the world, and shows how to apply their ancient wisdom to our own gardens. With interest in natural, sustainable, organic and local food at an all-time high, people are looking beyond their farmers markets and CSA cooperatives to hyperlocal ways of growing healthy, delicious produce in urban gardens and their own backyards. Culture and Horticulture details time-tested methods that are as effective today as they were hundreds of years ago. On the practical front, the book works as a manual for creating and maintaining a bountiful harvest. It explains how to build the soil to maintain fertility; how to produce compost; how to plant, sow, and tend the various fruit and vegetable plants; how to rotate crops and practice companion planting; how to set up a favorable microclimate; how to deal with so-called weeds and pests; how to harvest at the right time; and finally how to store vegetables and herbs. Special emphasis is given to the art and science of composting, the compost being the "heart" of any self-sufficient garden and a model for the cycle of life, death, and rebirth. At the same time the reader is introduced to the wider aspects of horticulture, to its historical, philosophical, and cosmological contexts and social relevance. Gardening is a cultural activity, shaped by peoples' thoughts, wishes, and needs as well as by their cultural traditions. The author, an anthropologist by profession who has investigated the gardening practices of indigenous people throughout the world and worked for many years on biodynamic farms and in his own food garden, will introduce the reader to Rudolf Steiner's vision of the garden as an organic unit, embedded in the context of terrestrial and cosmic forces. Storl explains the importance of cosmic rhythms (solar, lunar, and planetary), the role of biodynamic herbal preparations as "medicines" for the garden organism, and the so-called "etheric" and "astral" forces. The book presents a vision of the garden as seen through the eyes of "Goethean science," a magical place where alchemical transformations of material substances take place.
