G82-587 Understanding Potassium For Crop Production In Nebraska, George W. Rehm
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide discusses the availability of and the need for potassium in Nebraska soils
Potassium (K) is an essential nutrient absorbed from soils by crops in relatively large amounts. Therefore, it is classified as a major nutrient. Although large amounts are absorbed, potassium is not necessarily needed in a fertilizer program. Numerous studies conducted with all major crops have definitely shown that adding potassium to a fertilizer program does not lead to yield increases on the large majority of soils in Nebraska.

G82-630 Concrete Construction: Obtaining Quality Results, David P. Shelton, James M. Harper
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide describes the prior planning, site preparation, forming, ordering, placing, finishing, jointing and curing needed for successful concrete construction projects, especially slabs or flatwork.
Concrete is an excellent construction material for many agricultural applications. By paying careful attention to some major considerations, quality concrete construction can be achieved. The result can be years of reliable service.
