Nitrogen, Sulfur, Potassium and Phosphorus Fertilization in Alfalfa When Are They Necessary?
Determining when applications of nitrogen (N), sulfur (S), potassium (K) and phosphorus (P) fertilizer are needed is important to maintain alfalfa yield and quality. The Western U.S. is diverse in terms of climate, soil types, irrigation water need and availability, historical nutrient use and alfalfa production systems. Therefore, few generalizations hold regarding the timing and location of N...
متن کاملProkaryotic Communities at Different Depths between Soils with and without Tomato Bacterial Wilt but Pathogen-Present in a Single Greenhouse
The characterization of microbial communities that promote or suppress soil-borne pathogens is important for controlling plant diseases. We compared prokaryotic communities in soil with or without the signs of tomato bacterial wilt caused by Ralstonia solanacearum. Soil samples were collected from a greenhouse at two different depths because this pathogen is present in deep soil. We used sample...
متن کاملKentucky's Soils Potential for Alfalfa Production
A description of Kentucky's land base indicates that of nearly 15 million acres suitable for cropland usage, approximately three-fourths bas an erosion hazard potential of some degree, relating largely to steepness of slope (1). For this reason, there is a large potential acreage of alfalfa and other perennial forage crops relating to their sod forming growth habit which provides them an inhere...
متن کاملPhosphorus Runoff Losses from Alfalfa
Phosphorus (P) released from plants after freezing at the end of the growing season may be a contributor to P in runoff from agricultural landscapes. We evaluated P release from alfalfa (Medicago sativa L.) and mixed grass species [mainly quackgrass (Agropyron repens)] after freezing or drying in laboratory and field studies. Freezing released 18-30 % of the total P as dissolved reactive P (DRP...
متن کاملEfficiency at different interaction depths in large coplanar CdZnTe detectors
This paper presents some studies performed with a state of the art large volume, 1.5 cm diameter 1.0 cm thick, cylindrical CdZnTe coplanar detector with a new anode pattern design in the line of units previously reported. The absolute efficiency of the detector for different interaction depths is quantified. The detector’s ideal response is simulated with a Monte Carlo code and compared with ex...
