Mineralization of soil organic matter is governed by predictable factors with nitrate-N as the end product. Crop production interrupts the natural balance, accelerates mineralization of N, and elevates levels of nitrate-N in soil. Six factors determi

Resin-extraction techniques obtain a suite of extractable elements/ions from a single sample. They are, therefore, capable of characterizing interactions between nutrients and toxic ions on plant growth and of aiding in identification of genetic char

Measurement of soil organic carbon (OC) is slow and expensive when inorganic carbon (IC) is present. Our objective was to develop an automated volumetric IC analysis system, thus allowing OC to be determined by difference. The system was developed by

Wagon wheel ruts are still visible along pioneer trails in the USA, which suggests that vehicular traffic can modify soil properties for a century. We compared physical properties of a Barnes loam (fineloamy, mixed Udic Haploboroll) across three tran

Methods for extraction of metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] from soil are tedious and time-consuming. Existing robotic stations were adapted to provide an automated multistep method of metolachlor

Soil compaction by heavy axle load farm machinery can inhibit optimum plant growth. Uptake of essential nutrients, like P and K, is influenced by soil compaction. This study describes plant P and K accumulation from a compacted Webster (fine-loamy, m
