Nutrient elements in form of dissolved ions in soil solution have to come in contact with the plant roots for

Plant roots perform double functions of anchoring the plants firmly to the soil and as organs for nutrients and water

A nutrient elements such as nitrogen or zinc is referred to as an essential element if it satisfies the three

The growth and general performance of any plant depend on an adequate supply of environmental factors including the sixteen elements

The processes of surveying and mapping enable us to recognize and correlate different soil categories. Soil surveying is the process

Before soils could be classified, knowledge of individual soils which constitute the group is very essential. A soil survey makes

In general, two broad kinds of soil classification are recognized; a Natural or Taxonomic Classification also termed scientific classification, and

Owing to the existence of several thousands of types of soils throughout the world, it is necessary to classify them

Soil physics is a branch of soil science that deals with the study of soil physical conditions. It is necessary

Compost is of high value in agriculture and horticulture for improving soil structure and water retention property of the soil

There are different methods of composting organic materials. For the purpose of this class we are going to concentrate only

1. Materials for composting Materials used for composting should be all organic materials. In general, any type of organic materials

The decomposition of organic wastes in soil occurs naturally at ambient temperature to produce humus. The humification process occurs very

Organic matter affects both the biological, chemical, and physical properties of the soil and hence its fertility and health. Some

Organic matter affects both the biological, chemical ,and physical properties of the soil and hence its fertility and health. Some

Organic matter affects both the biological, chemical, and physical properties of the soil and hence its fertility and health. Some

Organic matter affects soil properties of the soil and its overall health. Properties influenced by organic matter include: soil structure;

Agricultural practices can have either positive or negative impacts on soil organisms. Land management and agricultural practices alter the composition

The easiest and most widely used system for classifying soil organisms is by using body size and dividing them into

Soil organisms represent a large fraction of global terrestrial biodiversity. They carry out a range of processes important for soil

The following are the major factors affecting organic matter decomposition; 1. Climate Climate, i.e. precipitation and temperature, influence the amount
