Excess water may be removed through channels, pipes or funnels either from the surface of land or beneath the soil. <br> <h2>Types of Drainage (Drainage Systems)</h2> There are two major types of drainage. These are: <ul> <li>Surface drainage</li> <li>Sub-surface/underground drainage</li> </ul>   <h3>Surface Drainage</h3> This is the removal of excess water from the surface of the farmland using constructed open ditches, field drain, land grading and lateral ditches. This is divided into; <ul> <li>Random field surface drainage</li> <li>Parallel field drainage</li> </ul> Random field surface is suitable for areas with pot holes or depressions (rough topography). Parallel field drain is ideal where fields are flat or less than 1 – 2% slope. <img class="size-full wp-image-52580 aligncenter" src="https://classhall.com/wp-content/uploads/2019/08/drainage-prarallel-field-drain.jpg" alt="Drainage - parallel field drainage" width="534" height="283" /> <p style="text-align: center;">Parallel Field Drain</p>

Anatomy, Physiology and Reproduction of Farm Animals

<h1>ANATOMY, PHYSIOLOGY AND REPRODUCTION OF FARM ANIMALS</h1> CONTENT <ol> <li>Parts of Farm Animals</li> <li>Organs of Farm Animals</li> </ol>   <h2>Parts of Farm Animals</h2> Anatomy can be defined as scientific study of parts and structures of farm animals while physiology refers to the way in which the bodies of farm animals function. The understanding of these helps the farmers to know how they function and be able to manage the animals effectively. Animals’ body can be broadly divided into four, namely: <ol> <li>The Head: This consists of the uppermost parts of the animals’ body. The most important organs that are necessary for the survival and effective functioning are found in the head e.g. brain, eyes, ears, nose and mouth.</li> <li>The Thoracic Cavity: This consists of the chest region of the animals. It houses important body organs such as the heart, the lungs and Trachea.</li>

Farm Surveying

It can further be defined as the process of measuring and mapping out the position, height, size and boundary of an area of farmland.   <h2>Types of Farm Survey</h2> There are five types of farm survey, namely: <ol> <li><strong>Chain Survey</strong>: This is the simplest form and the oldest form of survey involving the use of chains or measuring tapes to determine the area of land</li> <li><strong>Geodetic/Traverse Survey</strong>: It is a type of survey in which the size and shape (spherical) of an area is determined by using prismatic compass</li> <li><strong>Soil Survey</strong>: This is concerned with the examination, classification and systematic mapping of the soil. It provides data on the composition and properties of the soil</li> <li><strong>Topographical Survey</strong>: This is a type of survey in which the physical features of an area or relief,shape are identified eg flatness, steepness, valley, rivers etc</li> <li><strong>Aerial Survey</strong>: It is the use of aircraft to observe a large area of land showing different features such as hills, vegetation, rivers, lakes, Clift etc</li> </ol> <br> <h2>Importance of Farm Surveying</h2> Farm surveying is important for the following reasons:
