Soils Laboratory Manual: K-State Edition, Version 2.0, Colby J. Moorberg, David A. Crouse

NPP eBooks

The Soils Laboratory Manual, K-State Edition is designed for students in undergraduate, introductory soil science courses. The manual highlights the multidisciplinary aspects of soil science with laboratories focused on soil formation, classification, and mapping; soil physics, soil biology; soil chemistry; and soil fertility and management. The lab manual includes 16 different laboratories, each one starting with an introduction and pre-lab assignment, followed by in-lab activities, and complimented by a post-lab assignment. In-lab activities involve field trips, experiments, observation stations, or problem sets. Post-lab assignments include online quizzes, problem sets, or laboratory summary reports.

Version 2 of the lab manual exhibits …

Types of cited resources include extension bulletins, USDA NRCS conservation practice standards, and other government reports and resources. Cited resources are generally concise, easily read, and meant for general audiences. Annotations and images are used to provide context for each resource. Many contributors made Soil and Water …

Surface Runoff Characteristics From Claypan Soil In Southeastern Kansas Receiving Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski

Kansas Agricultural Experiment Station Research Reports

Preliminary results show that two-year average total nitrogen (N) runoff losses and ortho-phosphorus (P) and total P runoff losses in the second year were greater with N-based turkey litter/no-till applications than P-based turkey litter or fertilizer-only applications. Incorporation of turkey litter applied based on N requirements resulted in N and P losses that did not differ from losses from P-based or fertilizer-only treatments. Chemical and statistical analyses of third-year samples will allow for final results and interpretation.

Tillage Study For Corn And Soybean: Comparing Vertical, Deep, And No-Till, E. A. Adee

Kansas Agricultural Experiment Station Research Reports

The need for tillage in corn and soybean production in the Kansas River Valley continues to be debated. The soils of the Kansas River Valley are highly variable, with much of the soil sandy to silty loam in texture. These soils tend to be relatively low in organic matter (<2%) and susceptible to wind erosion. Although typically well drained, these soils can develop compaction layers under certain conditions. A tillage study was initiated in the fall of 2011 at the Kansas River Valley Experiment Field near Topeka to compare deep vs. shallow vs. no-till vs. deep tillage in alternate years. Corn and soybean crops are rotated annually. This is intended to be a long-term study to determine if soil characteristics and yields change in response to a history of each tillage system.
