4-4 Ring number by urine application frequency interaction (P < 0.001) on total-season
herbage N concentration during 2006. Ring number effects were linear for three (P <
0.001) and for two (P < 0.001) applications, but not significant for one (P > 0.171)
and zero (P > 0.128) urine applications. Standard error of a treatment mean was 0.25
g kg-1. Ring Numbers 1 through 4 refer to sampling areas 0 to 15, 15 to 30, 30 to 45,
and 45 to 60 cm from the center of the urine application, respectively...........................102
4-5 Ring number X urine application frequency interaction (P = 0.054) for in vitro
digestible organic matter (IVDOM) concentration during 2006. Ring number effects
were linear (P<0.0001) for two applications of urine and not significant for three (P
> 0.144), one, and zero applications (P > 0.272). Standard error of a treatment mean
was 2.4 g kg-1. Ring Numbers 1 through 4 refer to sampling areas 0 to 15, 15 to 30,
30 to 45, and 45 to 60 cm from the center of the urine application, respectively ..........105
4-6 Ring number X urine application frequency interaction (P < 0.001) for bahiagrass
herbage N harvested during 2006. The ring number effect was linear for three (P <
0.001), two (P < 0.001), and one urine application (P < 0.001) and there was no
effect of ring number (P >0.167) for the no urine control. Standard error of a
treatment mean was 1.2 kg ha-l. Ring Numbers 1 through 4 refer to sampling areas 0
to 15, 15 to 30, 30 to 45, and 45 to 60 cm from the center of the urine application,
respectively .............................................................................108
4-7 Ring number X dung application frequency interaction (P = 0.019) for bahiagrass
herbage N harvested during 2006. The ring number effect was quadratic (P = 0.048)
for three applications and linear (P < 0.001) and quadratic (P = 0.007) for two dung
applications, but was not significant (P > 0.288) for one and no dung applications (P
> 0.167). Standard error of a treatment mean was 1.5 kg ha-l. Ring Numbers 1
through 3 refer to sampling areas 0 to 15, 15 to 30, and 30 to 45 cm from the center
of the dung application, respectively. ........................................ .......................... 109
4-8 Ring number X urine application frequency interaction (P < 0.001) for bahiagrass
herbage P harvested during 2006. Ring number effects were linear (P < 0.001) and
cubic (P = 0.0419) for three urine applications, linear for two (P < 0.001) and one
application (P = 0.019), and not significant (P > 0.194) for zero applications.
Standard error of a treatment mean was 0.4 kg ha-l. Ring Numbers 1 through 4 refer
to sampling areas 0 to 15, 15 to 30, 30 to 45, and 45 to 60 cm from the center of the
urine application, respectively. ........... .............. ............... 111
4-9 Ring number X dung application frequency interaction (P = 0.058) for bahiagrass
herbage P harvested during 2006. Ring number effects were quadratic (P = 0.073) for
three dung applications, linear (P = 0.004) and quadratic (P = 0.046) for two
applications, and not significant for one (P > 0.257) or for zero applications (P >
0.289). Standard error of a treatment mean was 0.4 kg ha-l. Ring Numbers 1 through
3 refer to sampling areas 0 to 15, 15 to 30, and 30 to 45 cm from the center of the
dung application, respectively. .................................................. ............... 112
