Produktbeschreibung
Excerpt from Field and Laboratory Studies of Soils: An Elementary Manual for Students of Agriculture This little book of soil experiments has been prepared in response to the demand for a brief laboratory and field course in elementary soils, which may be given without the purchase of expensive equipment. With a few tools and the aid of the pupils, the teacher should be able to construct all of the apparatus necessary for many of the exercises. Such cooperation on the part of the students will stimulate a keener interest in the work than can be secured by the exclusive use of purchased materials. However, as funds become available, it is advised that special equipment be purchased and substituted for the less satisfactory, home-made apparatus. In many schools apparatus from the chemical and botanical laboratories will be available for the soil work. For example, a good balance may be purchased for the joint use of the chemical and soils laboratories, and the compound microscope may serve for both botany and soils. The first purchase of equipment should include the following: 1. Gasoline or kerosene stove with oven. 2. Balance similar to the one shown in Exercise A-7. 3. Soil auger and spade. 4. Small equipment, such as sample cans, glass tumblers, tin cans, wrapping paper, cheese cloth and twine. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
