Slope is the incline or gradient of a surface and commonly is expressed in percents. Dense soil will hold water, while loose soil will allow water to pass through quickly. Soil is natural habitat for Plants and animals. The study of soil is important in many respects. Structure of Soil Water 3. Soil drainage refers to the soil’s natural ability to allow water to pass through it. Drainage 19 Fertilizer and pesticide use 19 Practices that increase soil organic matter 19 Increased biomass production ... 2 The importance of soil organic matter., 3. Soil drainage poses particular challenges in Ireland. 6. Soil texture has an effect on soil fertility, influences compaction and crusting of the soil and workability - the ease with which soil can be tilled. The great variety of soils and soil problems means that every drainage challenge is unique. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. Soil science is the key factor in food production and is at the forefront of environmental and natural resource issues such as land use, soil The study of soil is helpful in practices of agriculture, horticulture, forestry, etc., such as culti­vation, irrigation, artificial drainage and use of fertilizers. The science of land amelioration, or “Kulturtechnik” as it is called in Germany, where it has been chiefly developed, is concerned with the scientific principles underlying the improvement of agricultural land by such means as artificial soil drainage, irrigation, river regulation and land reclamation. All plants have a particular need for certain amounts of water at their root area. If there is too much salt, plant growth will be retarded. During drainage, a finite suction is recorded before a soil begins to desaturate and this suction is often larger than the suction existing immediately after drainage starts. Drainage of land has been an important beneficial water management tool for improving crop production around the world. Poor soil structure has coarse, very firm clods or no structure at all. They provide the food, fiber and foundation of our existence. 2 Irrigation water sources and methods of storage, water and soil relationship, salt accumulation and leaching, Water flow through the soil… Taking out a spade to examine soil structure and biological activity can reveal a lot about the health of our soils. Soil aggregates (crumbs, or clumps) are formed when soil minerals and organic matter are bound together with the help of organic molecules, plant roots, fungi and clays. In others, soil amendments and subsoil analysis may ensure structural integrity. Three size classes are particularly important: Sand (size as in beach sand) Silt (size like talc/talcum powder) Clay (small particles which stick together, like modeling clay). Importance of Soil Water 2. It reduces the occurrence of soil erosion Careful investigation of the site; professional diagnosis; prudent assessment of the costs/benefits; expert implementation of a planned project and due consideration of environmental factors are all essential. A well aggregated soil is good for plant growth because the wider range of pores provides better drainage, aeration and water storage and places for roots to grow. Careful drainage methods must be considered, because clay's dense, tightly bound nature is impenetrable by water when compacted. Soil conservation is important because soil is crucial for many aspects of human life as it provides food, filters air and water and helps to decompose biological waste into nutrients for new plant life. Soil structure is important for plant growth, regulating the movement of air and water, influencing root development and affecting nutrient availability. Soil Texture:-Soil texture refers to relative proportion of mechanical / soil separates below 2 mm in diameter (viz. Soil science is the study of the soil as a component of natural and man-made systems. Soil Drainage. In addition, the texture of a soil and its clay content are the most important factors that determine the amount of air in the soil and its water-holding capacity - how easily water is retained in the soil. matter sand, silt and clay). Soil contains the air, water and food that provides a suitable place for plants to grow. It is an anchor for roots and also holds water needed by plants for moisture. There are a few different additives that will make your soil drain better and also help with nutrition. Soil and water are our most important resources. To remove the excess salts from the soil, leaching is encouraged. Soil, water and climate define the physical constraints to ecosystems, and the interpretation of these along with their costs and benefits supports the development of policy and sustainable management strategies. ... 85 + MCQs on Soil Science (with Answers) June 18, 2018. IMPORTANCE OF GOOD DRAINAGE. The study of soil is known as Soil science or Pedology (pedos = earth) or Edaphology (edaphos = soil). “Soil is a natural body developed by natural forces acting on natural materials. In preparation for planting our pumpkin crop this year, Farmer Rick is making drainage improvements for the garden areas. Methods of Expression 6. Soil is important to plants because it stores nutrients and serves as a medium for growth. provides supports plants supports structures stores and purifies water serves as a biological filter Our responsibility Different Forces of Retention 4. Experiments to measure the oxygen consumption of soils and plant root systems under near‐field conditions are briefly described and a method outlined of measuring the rates of diffusion of gases in soil in situ. Soil water, good or bad, may be the single most important factor in plant growth. Two methods are described at the start of this article. The fifth and final way to improve soil drainage is to use additives in your soil. The Soil Science and Hydrology major provides students with training in three key areas; soil, water and climate, and their links with functional, resilient and productive ecosystems. Founded in 2003, Science News for Students is a free, award-winning online publication dedicated to providing age-appropriate science news to learners, parents and educators. Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. Soil Structure and Consistency:- It provides water and nutrients to the living organisms. Soil sampling: The proper soil sampling procedure is an important first step in soil analysis. Its importance is reflected in the fact that this volume represents the third time that the American Society of Agronomy has published a monograph on this topic in the past 40 years. Soil organism, any organism inhabiting the soil during part or all of its life. Principles of Soil Science Marty Petrovic Introduction What is soil? Drainage is a very important part of any city. Drainage Class 9 Important Questions Social Science Geography Chapter 3 Important Questions for Class 9 Social Science Geography Chapter 3 Drainage Drainage Class 9 Important Questions Very Short Answer Type Questions Question 1. Good quality soils are friable (crumbly) and have fine aggregates so the soil breaks up easily if you squeeze it. Organic Material (Compost or Manure) Organic material is the most common and well-known additive to improve soil drainage. To decide which drainage system to install, you must first determine: the soil's characteristics; its permeability (speed at which water can move through the soil) suitability for mole drainage (clay type and content). Soil Fertility. Agricultural soil scientists develop methods that will improve the use of soil and increase the production of food and fiber crops. Soil drainage may determine which types of plants grow well in it. Energy Concepts 5. Drainage also makes it possible to inhibit soil salinity. Farmers and drainage contractors can often decide which subsurface drainage system to use based on some simple on-farm tests. Aloe vera grows best in sandy soil that drains well. Question 2. Drainage can be collected and saved for future use during periods of dry weather. Soil drainage poses particular challenges in Ireland.
