Learning Objectives - Soils and Forage Establishment
Understand the features of soil (i.e., texture, structure, chemistry, fertility,...) that are important for forage establishment
Understand how to calculate pH
Understand the importance of adjusting soil pH and when it is best to apply lime
Understand the proper timing and methods for soil testing
Know how pH affects nutrient availability
Understand the impact of lime-coated seed on soil pH, seedling establishment, and seed costs
Understand the importance of P and K on seedling establishment
Understand how nutrients interact with the soil, and how this can alter bio-availability to plants
Be able to calculate nutrient removal by forages given information on yield and tissue nutrient analysis
Understand the benefits and problems associated with applying N at seeding
Understand the impact of N fertilization on a grass-legume mixture
Know the proper seeding rates and seeding depths for the forage species we have discussed in class
Understand how to select forage species suitable to a particular site
Know the most suitable times to seed forage grasses and legumes and why
Understand the reasons for seedling death during establishment
Understand the proper use of a companion crop for establishing forages
Be aware of the implements that can be used to seed forages and their strengths and limitations.
Understand the best management practices for no-til establishment of forages
Be able to compare and contrast broadcast seeding and drilling as methods for forage establishment
Know how a seedbed must be prepared for successful forage establishment
Know how weed control impacts successful establishment of forages, and methods that can be used to control weeds
Understand why seeds fail to germinate, may not emerge, and may fail to grow after emergence ("Why Forage Seedings Fail" handout)
