SOILS, SOIL CHARACTERISTICS AND SOIL MANAGEMENT

SOILS, SOIL CHARACTERISTICS AND SOIL MANAGEMENT Introduction 1 The success of many civilizations has been determined by the quality of their soil resources. Furthermore, most civilizations have remained great only as long as they have properly managed the soil. Many productive soils have been worn out by depleting the fertility and allowing excessive erosion. Modern day use of fertilizer can help replenish fertility, but good soil MANAGEMENT is still important to maintain high productivity. Soils differ greatly in their ability to produce agricultural crops. Our soils have developed from a diversity of materials and under a wide range of environmental conditions.

SOIL SAMPLING AND SOIL TESTING - Agronomy

www.agronomy.k-state.edu

Soil sampling is the foundation upon which the entire soil testing/nutrient management planning process rests. If the foundation is bad (soil sampling technique), the integrity of the whole house built upon this foundation is questionable (nutrient management decisions). As a result, it is very important that the people collecting soil samples be

macro nutrients. Secondary nutrients are macronutrients but are less frequently deficient in soils. Micronutrients, also known as trace or minor elements, are required in very small amounts and are less frequently deficient. Even though nutrients are used in different amounts, each of the essential nutrients is equally important for plant growth.

the developing kernels. The amount of production that occurs is determined by 1) the potential set during the early stages of development; 2) the size of the “factory” that developed during the middle portion of the growth of the plant; and ) the production of the plant during the final stage of the growth cycle.

Pick up some of the rocks you find along the way. Take a close look at the rocks. Discuss any observations your child makes about the rocks, paying particular attention to the textures, layers, grain sizes, or other features. Have your child explain how each rock may have been affected by weathering and erosion.

rock phosphate. It often needs to be added to soil. Signs of phosphorus deficiency appear first on older or lower leaves that look red, purple, or dark green. Growth is stunted. Potassium helps form proteins, carbohydrates, and chlorophyll. It is important to proper func-tioning of stomates and the uptake of other nutrients.
