on this site led to the discovery of K deficiency in cotton, which had been referred to earlier as “cotton rust” (Atkinson, 1891, 1892). Today, the experiment is a 3-year rotation of: 1) cotton followed by crimson clover, 2) corn harvested for grain and followed by winter wheat, and 3) soybeans double-cropped after the small grain is harvested. The soil is a Marvyn loamy sand (fine-loamy, silic...

Nodular fasciitis is a rare benign lesion. Here we report a case of post-auricular nodular fasciitis, which was misdiagnosed by fine-needle aspiration cytology (FNAC) as pleomorphic adenoma. An 18-year-old male presented at Al-Nahdha Hospital, physical examination revealed a right post aural firm immobile mass. Radiology suggested the presence of a hypo-dense to iso-dense subcutaneous mass. The...

Plant metabolic activity in arid and semi-arid environments is largely tied to episodic precipitation events or ‘‘pulses’’. The ability of plants to take up and utilize rain pulses during the growing season in these water-limited ecosystems is determined in part by pulse timing, intensity and amount, and by hydrological properties of the soil that translate precipitation into plant-available so...

BACKGROUND The diagnostic accuracy of fine needle aspiration cytology (FNAC) of salivary lesions is relatively high, but cytologic interpretation might be confusing if the sample is lacking typical cytologic features. METHODS There were 77 cases of benign salivary lesions, consisting of pleomorphic adenoma (PA) in 61 cases, Warthin's tumor (WT) in 12 cases, and other benign lesions in 4 cases...

Attributes of fine roots (<LO mm diameter) were quantified in five southern Appalachian plant communities along an elevational gradient. These attributes include the seasonal dynamics of fine root mass and length, the depth distribution of fine roots, fine root width and, most importantly, the annual appearance and disappearance of fine roots. The principal objectives of this study were two-fol...

BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

The adoption of no-till management practices has increased in the United States over last decade. In state North Dakota, approximately 5.7 million hectares cropland is managed under or conservation tillage practices. Even though known for building soil health, increasing organic matter, capturing moisture, and reducing wind water erosion, it also presents a unique best practice since an mass cr...

Minimizing the risk of nitrate contamination along the waterways of the U.S. Great Plains is essential to continued irrigated corn production and quality water supplies. The objectives of this study were to quantify nitrate (NO(3)) leaching for irrigated sandy soils (Pratt loamy fine sand [sandy, mixed, mesic Lamellic Haplustalfs]) and to evaluate the effects of N fertilizer and irrigation mana...
