looking Into Crop Tissue
A scientist with the USDA has adapted computed
tomography (CT) scan technology to study how water and pathogens move through a plant’s
vascular tissue, known as xylem. In particular, CT technology will help scientists
determine how plants respond to water
stress and other changing
conditions.

Corn Needs More
Although advances in biotechnology have
dramatically increased corn grain yields, soil
test values indicate that producers might not
be supplying optimal nutrient levels, and
many current nutrient recommendations
could need adjusting."Current fertilization practices may not match the uptake
capabilities of hybrids that contain
transgenic insect protection and that are
grown at planting densities that increase
by about 400 plants per acre per year,"
said University of Illinois Ph.D. student
Ross Bender. Nutrient recommendations may not be calibrated to modern,
higher-yielding genetics and management. Study results indicated that higher
amounts of nitrogen (N), potassium (K),
phosphorus (P) and sulfur (S) are needed
to maximize crop growth.
