Based upon "wheat, winter, hard" crop record.
Reference:
"Using Cattle Feedlot Manure to Control Wind Erosion"
N.P. Woodruff, Leon Lyles, J.D. Dickerson and D.V. Armbrust
Journal of Soil and Water Conservation, Vol. 29, No. 3, May-June 1974
15 tons wet (66% wc) manure (5 tons dry wt.), surface applied approx. equal to 500 lbs of anchored surface wheat straw.
23 tons wet (66% wc) manure (9 tons dry wt.), incorporated approx. equal to 500 lbs of anchored surface wheat straw.
Adjusted the "mass to cover" value to reflect the difference in wind erosion effectiveness between wheat straw
and manure on a mass basis.
Changed the residue type to "Fragile, very small residue" to reflect the significant decline of the manure's effectiveness
at controlling wind erosion if incorporated into the soil.
