Fertilizer Industry

Fertilizers

The increasing number in population means higher demand for food. Threats in agricultural production such as pests, loss of soil fertility and lack of nutrients may result in low percentage of plants to harvest. If these problems are not addressed, there would not be enough crops which compose a big …

Fertilizers Made from Wastes

Industrial waste materials are often used in fertilizers as a source of zinc and other micronutrient metals. Current information indicates that only a relatively small percentage of fertilizers is manufactured using industrial wastes as ingredients, and that hazardous wastes are used as ingredients in only a small portion of waste-derived …

Factors Controlling Soil Reactions

Soil reaction varies due to following factors 1. Nature of soil colloids: The colloidal particles of the soil influence soil reaction to a very greatest extent. When hydrogen (H+) ion forms the predominant adsorbed cations on clay colloids, the soil reaction becomes acid. 2. Soil solution: The soil solution carries a number …

Active Soil Forming Factors

The active soil forming factors are those which supply energy that acts on the mass for the purpose of soil formation. These factors are climate and vegetation (biosphere). 1. Climate: Climate is the most significant factor controlling the type and rate of soil formation. The dominant climates recognized are: Arid climate: The …

Soil Forming Processes

The pedogenic processes, although slow in terms of human life, yet work faster than the geological processes in changing lifeless parent material into true soil full of life. The pedogenic processes are extremely complex and dynamic involving many chemical and biological reactions, and usually operate simultaneously in a given area. …

Fundamental Soil forming Processes

Humification: Humification is the process of transformation of raw organic matter into humus. It is extremely a complex process involving various organisms. First, simple compounds such as sugars and starches are attacked followed by proteins and cellulose and finally very resistant compounds, such as tannins, are decomposed and the dark coloured substance, …

Specific Soil Forming Processes

The basic pedologic processes provide a framework for later operation of more specific processes Calcification: It is the process of precipitation and accumulation of calcium carbonate (CaCO3) in some part of the profile. The accumulation of CaCO3 may result in the development of a calcic horizon.  Calcium is readily soluble in acid …

Development of Soil Profile

The development of soil profile is a constructive process where in disintegrated material resulted from weathering of rocks and minerals gets converted into a soil body. Definition of soil profile: The vertical section of the soil showing the various layers from the surface to the unaffected parent material is known as …
