"The objective of this research was to evaluate field decomposition\nof 23 cereal grain straws. Straw samples of `Fieldwin' and 'Owens'\nsoft white spring wheats (Triticum aestivum L.) 'Borah' and 'McKay'\nhard red spring wheat; 'Nugaines', 'Daws', 'Lewjain', Stephens',\nand 'Hill 81' soft white winter wheats; 'Weston'; 'Manning', 'Neeley'\nhard red winter wheats; 'Advance', 'Steptoe', 'Lud', 'Pirolene', and\n'Klages' spring barleys (Hordeum vulgare L.); 'Kamiak', 'Boyer', and\n'Schuyler' winter barleys; Waid durham wheat (Triticum durum\nDesf.); and 'Flora' and 'Palouse' triticales (Triticale hexaploide Lart.);\nwere buried in field plots. The straw bags were removed at intervals\nduring 1 yr and analyzed for the amount of decomposition, and C\nand N contents. Final decomposition ranged from 54% for the Borah\nwheat straw to 75% for the Lud barley straw with about half of the\nstraws decomposing 64 or 65%. The hard red spring wheat and\ntriticale straws decomposed the slowest and two spring barley straws\ndecomposed most rapidly, but no completely systematic differences\nwere observed for different genera of straws. The original straw N\nconcentrations ranged from 2.2 to 12.5 g/kg. Nine straws lost N\nduring the incubation period from September to November while\neight increased in N concentration during this time. In the next three\nincubation periods, from November to the following October, nearly\nevery straw sample increased in N concentration. The total N weight\nin the straw increased to the May sampling and then decreased\nthereafter. This pattern indicates that the straw was releasing N as\nit was mineralized and became available for utilization by the growing\ncorn crop. Carbon/N ratios ranged widely in the initial straw\nsamples, becoming more nearly uniform as the decomposition process\ndeveloped. The C/N ratios remained fairly high avg 41 for the\nfinal sampling even though the straw in every case had released N\ninto the soil during the last sampling period. Regression analysis of\ntotal decomposition and change in weight of N in the wheat straw\nsamples for the first 67-d incubation in the field showed a linear\nrelationship with decomposition during the year, decreasing with\nincreasing N loss in the early stage."^^ .
