UNIT 4: Watering Crops Objectives By the end of this unit, you should be able to: 1. Describe the significance of soil moisture; 2. Measure soil moisture; and 3. Perform irrigation LESSON 1: Determining Soil Moisture Introduction Water is one of the primary requirements for a crop to survive and thrive. It is very critical to know what the water requirements of -our crops need. There will be various factors which affect the water requirement of crops such as climate factors, the crop type, and the soil type. For the first lesson, we are looking at the importance of understanding the soil moisture content in agricultural crops and we will be calculating the content to better understand our crop needs. Topic 1: Measuring Soil Moisture Topic 1: Measuring Soil Moisture Topic 2: Standardized Soil Moisture Index Reference  LESSON 2: Irrigation Systems Introduction Irrigation is the artificial application of water to soil to supply the moisture needed for the plant’s survival and growth. Additionally, irrigation provides crop insurance in case of short drought, cool the soil and atmosphere for the plant, wash out soil salinity, soften tillage pan and clods, facilitate the functioning of some microorganisms, and enhance the fertilizer application, or fertigation. Why is irrigation important? 1. It increases yield of crops 2. It provides means of production of special crops 3. It provides employment for farmers during the dry season 4. It increases the economy of a nation through export 5. It increases additional income to the farmer 6. It intensifies land use. Topic 1: Drip Irrigation Drip irrigation entails water application at a slower pace. In this system, pipes called dripper lines and drippers emit drops of water or fertilizer directly to the plant root zone. Drip irrigation is considered one of the most efficient water and nutrient delivery system for growing crops since it transfers them directly to the roots of the plants. Topic 2: Sprinkler Topic 2: Sprinkler Topic 3: Surface Irrigation Topic 4: Manual Watering Manual watering is the most common method for small- scale farms or backyard farms. Manual watering makes use of basic gardening tools such as cans or hoses. Without the need for technical equipment, water use can be controlled and ensures lesser loss of water. Reference Reference CREDITS: This presentation template was created by Slidesgo, Thanks! including icons by Flaticon, and infographics & images by Freepik
