Nutrient Management
Soils - Part 7: Soil and Plant Considerations for Calcium, Magnesium, Sulfur, Zinc, and other Micronutrients
The 16 essential elements for plant growth and the relative quantities of each needed by plants to grow normally will be discussed in this lesson. You will learn to identify the source of specific nutrients in the soil and how to identify specific fertilizer compounds needed in Nebraska. [This lesson, as well as the other nine lessons in the Soils series, is taken from the "Soils Home Study Course," published in 1999 by the University of Nebraska Cooperative Extension.]
Soils - Part 8: Characteristics of Fertilizer Materials
The various characteristics of fertilizer materials being sold on the market today will be discussed. You will learn to identify some of the consequences of using each type of fertilizer material and how that material was developed and manufactured. [This lesson, as well as the other nine lessons in the Soils series, is taken from the "Soils Home Study Course," published in 1999 by the University of Nebraska Cooperative Extension.]
Soils - Part 9: Fundamentals of Soil Testing
The major emphasis in this lesson is soil testing and understanding the procedures needed to take a representative soil sample. You will understand the term variability, how it affects soil tests, and how a soil test is developed. [This lesson, as well as the other nine lessons in the Soils series, is taken from the "Soils Home Study Course," published in 1999 by the University of Nebraska Cooperative Extension.]
Soils - Part 10: The Scientific Basis for Making Fertilizer Recommendations
The Scientific Basis for Making Fertilizer Recommendations: In this lesson, you will gain an understanding of the history of fertilizer use and the ideas behind fertilizer recommendations. Three major crop nutrition concepts will be discussed in terms of their benefits and disadvantages. [This lesson, as well as the other nine lessons in the Soils series, is taken from the "Soils Home Study Course," published in 1999 by the University of Nebraska Cooperative Extension.]
