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

The global population, now estimated at about 5.8 billion, is expected, barring some catastrophe, to reach 10 billion within the next 20 or so years. An increasing population in and of itself would pose growing pains if it were uniformly distributed

Cuphea is a new oilseed crop that has undergone agricultural domestication for approximately the past 20 years. Its seed is rich in small- and medium-chain fatty acids, which are highly valued for manufacturing soaps, detergents, personal care produc

Cuphea (Cuphea viscosissima× C. lanceolata ‘PSR 23’) seed contains oils that have industrial application. However, little is known regarding cuphea’s optimal mineral nutritional requirements or responses to inhibiting elements. Oil seed crops

A model of the water-holding characteristics of soil is needed to develop a systematic method for determining the value of organic C in soil. In the United States, available water-holding capacity (AWC) in soil is that water retained in soil between

Resin extraction of soils has revealed sensitivities of crops to the extractable V:(V + P) and Mg:(Mg + Ca) molar ratios. Consequently, we examined the Barnes and Buse soils in the northern Great Plains of North Dakota, South Dakota, and Minnesota. S

Relative soil aeration affects the surfaces upon which pesticides adsorb and non-ionic resins offer a means of observing and evaluating this factor. A non-ionic resin extractor, developed for pesticide extraction under reducing conditions, was used t

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

Soil [H+] and [OH-] have a major effect on the rate of microbial mineralization of organic matter and the subsequent expression of nitrate-N (NO-3-N). The objective of this work is a mathematical description of the effect of [H+] and [OH-] on express
