Effects Of Grazing Management On Pasture Production And Phosphorus Content Of Forage (A Progress Report), Mathew M. Haan, James R. Russell, Wendy J. Powers, Steven K. Mickelson, Syed I. Ahmed, John L. Kovar, Richard C. Schultz

Beef Research Report, 2003

In spring 2001, pastures were grazed at the ISU Rhodes Research and Demonstration Farm to determine the effects of grazing management on pasture productivity and phosphorus (P) content of forage. Treatments included an ungrazed control, summer hay harvest with winter stockpiled grazing, continuous stocking to a residual height of 2 inches, rotational stocking to a residual height of 2 inches, and rotational stocking to a residual height of 4 inches. Forage production was greatest in June and July, decreased in August, and had a slight rebound in September and October before going dormant in November. Phosphorus concentration of forage was ...

Effects Of Grazing Management On Sediment And Phosphorus Losses In Run-Off (A Progress Report), Mathew M. Haan, James R. Russell, Wendy J. Powers, Steven K. Mickelson, Syed I. Ahmed, John L. Kovar, Richard C. Schultz

Beef Research Report, 2003

In 2001 and 2002, pastures at the ISU Rhodes Research and Demonstration Farm were grazed to determine the effects of stocking treatment on nutrient and sediment loss from pastureland. Treatments included an ungrazed control (UG), summer hay harvest with winter stockpiled grazing (HS), continuous stocking to a residual height of 2 inches (2C), rotational stocking to a residual height of 2 inches (2R), and rotational stocking to a residual height of 4 inches (4R). At three times in 2001 (late spring, mid-summer, and fall) and four times in 2002 (early spring, late spring, mid-summer, and fall), rainfall simulations were conducted ...
