Soybean yield and soybean cyst nematode densities related to soil ph, soil carbonate concentrations, and alkalinity stress index
Soybean [Glycine max (L.) Merr.] grown on high pH, calcareous soils often suffer yield loss due to unavailability of Fe. Further yield decline can occur due to infestations by soybean cyst nematodes (Heterodera glycines Ichinohe; SCN) that are often present in greater numbers in high-pH soils. An observational study was conducted from 2001 to 2005 in Iowa to examine the relationships among: pH; ...

Determination of Clay Size Fraction of Marine Clays
This technical note describes a study on the effect of different dispersing agents and the quantity of same on the grain-size distribution and in particular the percentage of clay size. The results confirm that the existing practice of using 100 mL of standard dispersing agent, viz. sodium hexametaphosphate and sodium carbonate solution, is suitable for marine clays also. The clay size fraction ...

Capabilities of four novel warm-season legumes in the southern great plains: Grain production and quality
Grain legumes could serve as a low cost nitrogen (N) and energy source for animal production in the southern Great Plains (SGP). This study evaluated the yield and nutritive value of grains of tropical annual legumes novel to the SGP. Included were cultivars of pigeon pea [Cajanus cajan (L.) Millsp.] (cv. GA-2), guar [Cyamopsis tetragonoloba (L.) Taub.] (cv. Kinman), cowpea [Vigna unguiculata ...

Measuring grain protein concentration with in-line near infrared reflectance spectroscopy
The advent of near infrared (NIR) on-combine sensors gives growers the opportunity to measure the grain protein concentration of wheat (Triticum aestivum L.) during harvest. A study consisting of three sequential experiments (laboratory bench, combine test stand, and field) was conducted to evaluate the performance of an in-line, NIR reflectance spectrometer, referred to as the ProSpectra Grain ...

Multi-residue mycotoxin analysis of dry distillers grains
Distillers grains (DG) are the still residues after the ethanol has been collected. Approximately 90% of US production is used in domestic animal feed. Any Mycotoxins present in the fresh corn can be concentrated by a factor of three. Contamination can also occur during storage. This raises concern about the potential animal and human health hazards from the use of Mycotoxincontaminated ...
