Heavy harrow used to flatten standing stubble and redistribute and size flat residue. Typically used on small grain stubble resulting from yields greater than 60 bu/ac. This implement is set so the large coil tines do not dig into the soil, but rather scatter the straw between the ranks of tines. It's use to improve seed soil contact to encourage weed growth and volunteer growth 10-24-06 MAS G2 was added into file in front of the flattening (P24), burial (P25), and resurfacing (P26) factors because the area affected is less than 1.0 and the RUSLE values were normalized to 1.0. This change will imulate the correct residue changes based on the method set forth in RUSLE. RUSLE's factors have been redused to based on the area affected. The stalk fall rate factor (P34) was moved ahead of the new (G2) factor to set the fall rate to the less than 1.0 area affected. 8/7/07 MAS oenergyarea 3.2738733 ostir .15 G 01 gtdepth 25.400051 gtilint .1 gtilArea .1 gtstddepth 25.400051 gtmindepth 25.400051 gtmaxdepth 25.400051 P 01 P 02 rroughflag 1 rrough 6.096012 P 05 rdgflag 1 rdghit 0.0 rdgspac 0.0 rdgwidth 0.0 dkhit 0.0 dkspac 0.0 P 11 asdf 3.0 crif -0.22 P 12 soilos .2 P 13 laymix .1 P 31 kilflag 2 P 40 P 34 frselpool 7 ratemultvt1 3.0 ratemultvt2 2.5 ratemultvt3 2.0 ratemultvt4 1.5 ratemultvt5 1.0 threshmultvt1 0.5 threshmultvt2 0.6 threshmultvt3 0.7 threshmultvt4 0.8 threshmultvt5 1.0 G 02 gbioarea 1.0 P 24 fbioflagvt 0 massflatvt1 .8 massflatvt2 .7 massflatvt3 .6 massflatvt4 .6 massflatvt5 1.0 P 25 burydist 1 massburyvt1 .035 massburyvt2 .025 massburyvt3 .02 massburyvt4 .01 massburyvt5 .02 P 26 massresurvt1 0.01 massresurvt2 0.01 massresurvt3 0.01 massresurvt4 .01 massresurvt5 0.01
