Hardcover. Condizione: New. This book titled Mechanics and Characteristics of Soil deals with the said subject in its totality. Soil material is a critical component in the mining and construction industries. Soil serves as a foundation for most construction projects. The movement of massive volumes of soil can be involved in surface mining, road building and dam construction. Earth sheltering is the architectural practice of using soil for external thermal mass against building walls. Soil resources are critical to the environment, as well as to food and fibre production. Soil provides minerals and water to plants. Soil absorbs rainwater and releases it later, thus preventing floods and drought. Soil cleans the water as it percolates through it. Soil is the habitat for many organisms: the major part of known and unknown biodiversity is in the soil, in the form of invertebrates (earthworms, woodlice, millipedes, centipedes, snails, slugs, mites, springtails, enchytraeids, nematodes, protists), bacteria, archaea, fungi and algae; and most organisms living above ground have part of them (plants) or spend part of their life cycle (insects) belowground. Aboveground and below-ground biodiversities are tightly interconnected, making soil protection of paramount importance for any restoration or conservation plan. Covering the diverse needs of both the academic and professional communities, this classic text will be a must have reference for all those in soil science and related fields.…

Hardcover. Condizione: New. This book titled Fertilizer and Irrigation Analysis for Crop Production deals with the said subject in its totality. Sixteen elements are essential for plant growth. These are divided into two groups based on the amount of each needed by plants. The nine macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, carbon, hydrogen, and oxygen) are required in relatively large amounts. Of these, nitrogen, phosphorus, and potassium are the elements most commonly added as fertilizer. The seven micronutrients are required in smaller amounts. Iron and manganese are the micro-nutrients most often deficient in landscape plants. An adjustment in soil pH usually corrects deficiencies of the micronutrients. Each of these 16 elements has a specific role in plant growth. A deficiency or an excess of any one will impair plant growth until the problem is corrected.…
