Summary: No matter the particular plant scenario you are working with (ie field crop, pastureland, Greenhouse business, turf grass, home garden and landscaping, etc.) being able to accurately estimate the water needs and timing of irrigation will help lower costs, as well as preserve limited water supplies. In this lesson you will learn how to use a specific irrigation app which has been developed by a group of public researchers and is free for your use. This app, along with the foundational irrigation principles you learned in previous lessons and/or from your previous knowledge will help you maximize the effects of your irrigation applications while minimizing costs. This lesson uses a Colorado field example.

After completing this lesson, you will be able to:

• Set up a field in the Water Irrigation Scheduler for Efficient Application (WISE) App to schedule irrigations during one growing season.
• Input irrigation amounts in WISE based on estimated soil water deficits (D) and the crop’s management allowed depletion (MAD) during one growing season.
• Interpret the WISE water balance outputs.

Time Required: We estimate it will take you 2 hours to complete the lesson.  You can work on it at your own pace and do not have to complete it in one setting.

Who Would Benefit:  A variety of people will find this upskilling course useful from adults to high school students.  This includes careers (or hobbyists) growing plants (ie field crops, greenhouse production, turf and lawns, gardens, etc.) and wishing to save money and water by better timing irrigation applications.

Upskill Credentials: If you finish the entire course including passing a final quiz (which you can take up to 3 times), then you will earn a badge certificate of completion.  It has been approved for 2 Crop Management CEUs through the national Certified Crop Adviser program.

Summary: To effectively utilize limited irrigation resources in the most cost-effective manner requires balancing the inputs and outputs of water fluxes, as well as water that is stored in the soil profile. Best irrigation management scheduling practices focus on water balance in the rootzone because that is where the plant/crop is extracting water (and nutrients) from the soil.  It is here we estimate the irrigation water requirements to maintain healthy plants. Decisions on when and how much irrigation water to apply depends on the soil water deficit and the management-allowed depletion (MAD). This lesson will walk you through each of these concepts including real world problem scenarios.

After completing this lesson, you will be able to:

• Use the water balance of the root zone to estimate the irrigation water requirement. 
• Make irrigation decisions by comparing the soil water deficit to the management-allowed depletion.

Summary: Irrigation is defined as the watering of land (or other plant growth media) by artificial means to foster plant growth. This can be very costly and the availability of supplemental water may be scarce, so it is important to be able to calculate accurately how much water to apply and when. This lesson will introduce you the underlying concepts you will need to consider.

After completing this lesson, you will be able to:

• Explain how the systems approach can be used to manage water in irrigated systems. 
• Identify the fluxes (flows) of water and energy in an irrigated soil-plant-atmosphere system.
• Describe how the Irrigator’s Equation can be used to quantify the four (4) major variables involved in managing irrigation systems.
• Use the principle of conservation of mass to determine the water budget (also called water balance) of a soil-plant-atmosphere (SPA) system. 
• Use the principle of conservation of energy to determine the energy budget (also called energy balance) of a SPA system.

This CSU Badge introduces foundation principles on how internet-of-things (IoT) technology and sensors can be used to provide real-time soil moisture and weather data, allowing growers to improve the timing and amounts of irrigation – saving water and avoiding plant water stress. These general principles are applicable to either landscape or agriculture irrigation sectors, including a wide range of scenarios such as efficiently watering a backyard garden, growing vegetables in a greenhouse, maintaining golf courses and lawns, as well as irrigating large crop fields. Using a kit containing sensors and a wireless IoT microcontroller, participants will gaine hands-on experience building, programming, and using their own IoT (i.e, sensor-based) system to monitor soil water levels based on real-time data. Using an experiential learning approach, learners will gain new knowledge on how IoT sensor technology and the resulting real-time data can be leveraged to improve irrigation decisions and save water. Program was funded in part by the CHS Foundation and Colorado State University.

Summary: Seed conditioners play a unique role in modern seed production. Conditioners have the power to increase the quality of poor seed, and decrease the quality of good seed. While a grower has the ability to fine tune the conditions under which the seed crop is grown with fertilizer and water inputs, pest control and tillage to maximize quality, it is up to the conditioner to create the highest quality product out of what they are given. This course is second in a series which will walk you through foundational concepts of seed conditioning. 

Upskill Credentials: If you finish the entire course including passing the quiz with a score of 80% or better (which you can take up to 3 times) and filling out the short 5 mins feedback survey, then you will earn a badge certificate of completion.  This course is under review for CEUs through the national Certified Crop Adviser program.

Time Required: We estimate it will take you 1-2 hours in total to complete the course.  You can work on it at your own pace and do not have to complete it in one setting. Click on the eBook link below to begin.
