Soil Science In An Irrigation Perspective

Soil science is the study of soils, their properties we are discussing the same in an irrigation perspective.

Soil science is the study of soils, their properties and how they function in relation to plants. It is a field that combines many different scientific disciplines, including microbiology, mineralogy, physics and chemistry. This article will explore how soil science plays a role in irrigation management for field crops such as wheat and legumes. Pedology is the study of soils in their natural setting and has been equated with the study of soil genesis and soil classification. The people who study soils in these ways are pedologists.

Soil Science in Irrigation Perspective

Soil science is a science that deals with the study of soil. Soil is a natural resource essential for all living things and for sustaining human life. It is also an important component of our environment, as it provides vital functions such as water storage and filtration, nutrient cycling, climate regulation and erosion control.

Soil scientists work at the interface between agriculture, environmental sciences and engineering to gain an understanding of how soil responds to changes in climate or land use practices such as irrigation management (Irrigation Management), tillage practices (Tillage Management) or surface application methods such as dust suppression agents (Dust Control Agents).

Soil Scientific Knowledge

Soil scientific knowledge is a complex system consisting of soil science, soil chemistry, soil physics and earth sciences. It deals with the properties of soil and its components; the effect on them by human activities; and how to maintain or restore this natural resource for agricultural production. In addition to being a medium for plant growth, it plays an important role in water management by providing an efficient medium which allows roots access to nutrients needed for growth.

Soil can be classified according to its texture (consists of aggregates), structure (consists of coarse sand particles), mineralogy (consists mainly minerals) or paedology (consists of hydromorphic material).

Soil Physical character

Soil physical character is the physical characteristics of soil. It includes soil type, texture and bulk density.

Soil type refers to whether the soil is sand, silt or clay; and if it has high water content (high shrink-swell potential) or low water content (low shrink-swell potential).

Texture describes how loamy (soft) or sandy a soil is in terms of particle size distribution and structure. Bulk density refers to how much material there is within each cubic metre (cm³) at a given depth below ground level when compared with other similar materials such as gravels used for construction purposes where bulk density lessens over time due to compaction by heavy machinery moving through them as well as weathering processes which can cause this material to break up into smaller pieces known as fines which may not be recognized by any single person who looks at these particles under microscope because they're so small compared with normal sized rocks found elsewhere around us today!

Soil Chemical Character

Soil chemical characteristics are an important consideration in evaluating the suitability of a given site for irrigation. Soil pH and salinity, organic matter content and nutrient status can each be evaluated individually or as part of a whole-site assessment.

Soil pH: The acidity or alkalinity (pH) of the soil is determined by its mineralogy, which includes clay particles, silt or sand components; it also depends on how much calcium carbonate (CaCO3) is present. High levels of CaCO3 inhibit root growth due to their tendency to absorb water instead of allowing it to leach through them into the lower layers where plants grow roots.

Soil Biological Character

Soil biological activity is essential for soil fertility and plant growth, nutrient cycling and water infiltration. Soil biological activity can be defined as the sum of all soil micro-organisms, their activities or metabolic processes; they are responsible for decomposing organic matter in soils. They also kill pathogens that cause diseases on plants or animals.

Soil texture refers to how fine-grained (or coarse) a material is based on its particle size distribution. Texture can be measured using sieves ranging from 4 mm to 200 mm in diameter with larger sizes indicating coarser textured materials while smaller ones signify finer textured soils.

Principles of irrigation management

Before we begin, let's take a look at some of the most important principles that underlie soil science and irrigation management.

• Irrigation scheduling: Scheduling irrigation is one of the most important aspects of effective irrigation management. The schedule should be planned so that crops receive water as needed, but not too much at once or too little over a period of time. This requires knowledge about how much water your crop needs and when it will need it.
• Irrigation efficiency: You may want your garden to grow faster than what nature provides; however, this can lead to problems with excessive plant growth (or "oversaturation"), which results in poor quality fruit or vegetables due to rotting roots and nutritional deficiencies caused by excess nutrients being stored underground instead of being used by plants themselves through photosynthesis/photosynthetic processes

Irrigation water application management strategies for field crops

The irrigation water application management strategies for field crops include:

• The timing of the irrigation. As a rule, the crop should be irrigated when it is 15% to 30% dry and then again when it is 10% to 20%. This helps avoid any potential damage due to too much water at once.
• The amount of water used per acre. A good rule-of-thumb is that one inch of precipitation equals about one inch of water applied (roughly). For example, if we have only two inches of precipitation in an entire year but want our fields watered three times during those months, then at least four inches would need to fall on them before we could apply enough irrigation water so that all six inches were available for use by plants (instead of just two).

The Nature of the soil is very important for crops that use irrigation

The nature of the soil is very important for crops that use irrigation. Soil is a mixture of minerals and organic matter with a structure that can be classified in three ways:

• Structure – This refers to how closely packed the particles are in your soil, which affects how much water can be held by them.
• Texture – Texture refers to how rough or smooth the surface of your soil is (it’s not an absolute measurement). A smooth texture means no clods or pebbles will stick in it while digging holes or tilling your garden plot; this makes aeration easier. A rough texture means there will be more friction between different sized particles during tillage operations such as discing or mouldboard ploughing; this makes traction on equipment less effective at turning over the topsoil layer when you turn over a furrowed field bedding pattern where rows are spaced far apart from each other

In conclusion, soil science is an essential part of irrigation management. Irrigation water application strategies for field crops should be based on the nature of the soil and knowledge about its physical character (texture, structure), chemical character (nutrient availability and composition) and biological character (microorganisms).
