“…5). Indeed, runoff volumes in manured plots were lower than control plots (1.1 times) for the 6-mo rainfall event, supporting similar reports that manure application (in the long term) can reduce surface runoff volume (Hensler et al, 1970;Mueller et al, 1984;Bundy et al, 2001;Gessel et al, 2004). Manure P and tillage eff ects were no longer signifi cant.…”

Excessive manure phosphorus (P) application increases risk of P loss from fields. This study assessed total runoff P (TPR), bioavailable P (BAP), and dissolved reactive P (DRP) concentrations and loads in surface runoff after liquid swine (Sus scrofa domesticus) manure application with or without incorporation into soil and different timing of rainfall. Four replicated manure P treatments were applied in 2002 and in 2003 to two Iowa soils testing low in P managed with corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations. Total P applied each time was 0 to 80 kg P ha−1 at one site and 0 to 108 kg P ha−1 at the other. Simulated rainfall was applied within 24 h of P application or after 10 to 16 d and 5 to 6 mo. Nonincorporated manure P increased DRP, BAP, and TPR concentrations and loads linearly or exponentially for 24‐h and 10‐ to 16‐d runoff events. On average for the 24‐h events, DRP, BAP, and TPR concentrations were 5.4, 4.7, and 2.2 times higher, respectively, for nonincorporated manure than for incorporated manure; P loads were 3.8, 7.7, and 3.6 times higher; and DRP and BAP concentrations were 54% of TPR for nonincorporated manure and 22 to 25% for incorporated manure. A 10‐ to 16‐d rainfall delay resulted in DRP, BAP, and TPR concentrations that were 3.1, 2.7, and 1.1 times lower, respectively, than for 24‐h events across all nonincorporated P rates, sites, and years, whereas runoff P loads were 3.8, 3.6, and 1.6 times lower, respectively. A 5‐ to 6‐mo simulated rainfall delay reduced runoff P to levels similar to control plots. Incorporating swine manure when the probability of immediate rainfall is high reduces the risk of P loss in surface runoff; however, this benefit sharply decreases with time.

“…Hensler et al (1970) observed that runoff losses from manure applied to frozen ground were variable. During one winter when it rained after manure application, significant losses of P and N were observed.…”

“…Many factors affect the quantity of nutrients that are lost from agricultural fields. These include amount and timing of precipitation and thawing (frozen ground), soil conditions, volume of runoff, slope and proximity to surface water, air temperature, snow cover, soil temperature, and soil permeability (Midgley and Dunklee 1945, Converse et al 1976, Philips et al 1981, Hensler et al 1970, Steenhuis et al 1981, Bechmann et al 2005.…”

“…However, the conventional disposal method in its existing form may contribute to the nutrient pollution of surface waters. The results of various soil science studies suggest that nutrient pollution from animal manures could be reduced with the provision of storage facilities during the winter period and then spreading on the cropland during the spring period [4,7]. Similarly during the summer crop growing period, if land is not vacant, manure could be stored and spread in fall before frost and snow season.…”
