“…Conservation tillage practices are responsible for temporary immobilization of fertilizer-N and reduction in N availability to crops at early stages of growth [13]. Further, Surface-placed residues have reduced residue-tosoil contact, with greater fluctuations in temperature and moisture content, limiting the amount of time during which conditions are favourable for the decomposers [106]. Thus, it is imperative to understand the interaction between soil microorganism and its environmental factor to maintain soil fertility in relation to the sustainable crop production systems.…”

Summary Wastes generated from municipal and agricultural activities have the tremendous potential for application in agriculture as a source of nutrients and as amendments to improve soil organic matter (SOM). A decline in SOM can represent a serious threat to soil fertility and quality. Nitrogen (N) mineralization from organic amendments is important for understanding the N dynamics in terrestrial ecosystems. In this review, quality of the amendments such as C/N ration, N content, and biochemical compositions, etc. are discussed. Since, C/N ratio cannot explain all differences in N mineralization; emphasis has been laid on characterizing different compounds in organic amendments that govern the mineralization process. The importance of simulation models has also been described in modeling N mineralization from some complex materials like compost, animal manures and farmyard manures. These complex simulation models once modified according to the quality of the organic amendments can simulate N mineralization and thus, they can be used for simulating N dynamics in terrestrial eco-systems.

In order to develop the application method of compost manure (CM) and liquid manure (LM) for rice cultivation, experiments were conducted at silty loam paddy field in Gochang, Jeonbuk, a LM applied rate as N%; non-application, chemical fertilizer (CF) 100%, CM 50%+LM 50%, CM 30%+CF 70% and CM 30%+LM 70% as basal and additional fertilizer. NH 4 + -N content in paddy soil was higher with CF 100% application than the split application of compost and liquid pig manure fertilizer during the early stage of rice growth. However, there was no significant difference in the later part of rice growth. Amount of NO 3 --N in leachate was decreased in CM 30%+LM 70% and CM 30%+CF 70% split applications compared to CF 100%. Amounts of OM and Avail P 2 O 5 , Exch. cations in soil of experiment after were highest with the split application of CM 50%+LM 50% and CM 30%+LM 70%. Amount of nutrient uptake of plants were no significant difference between the split application plots of CM and LM, but nitrogen utilization rate was 66% in average CM 50%+LM 50% and CM 30%+LM 70% to compared CF 100%. The rice yield of CM 50%+LM 50% was lower (90%) comparing that of CF 100% (557 kg 10a -1 ). But the yield in CM 30%+CF 70% and CM 30%+LM 70% reached 96% in average, which did not show significant difference with that of CF 100%. Accordingly, LM 70% or CF 70% split application after CM 30% application was helpful in enhancing the physicochemical property of soil as well as reducing CF. It could be evaluated that this application in segmentation was better in productivity improvement and soil pollution reduction than the esinultaneous application of LM 100% in terms of split application in times of requirement for plants.

“…Thus the effect of burial on canola straw seems to be of the same order of magnitude as the effect of burial on cereal straw (Christensen 1986;Summerell and Burgess 1989). Since the difference in decomposition between buried and unburied straw was so much larger than the effect of cultivar differences, it would seem that considerable effort would be required to select cultivars that would increase decomposition as much as burial.…”

“…Over one year, buried wheat (Triticum aestivum L.) straw lost twice as much weight as straw left on the surface (Summerell and Burgess 1989), and after 14 mo, buried barley straw weighed only about onethird of that on the surface (Christensen 1986). However, since the effect of straw burial seems to vary with species (Schoenau and Campbell 1996) and since there have been few studies on canola straw decomposition, our first objective was to quantify the effect of burial on canola straw.…”

Blenis, P. V., Chow, P. S. and Stringam, G. R. 1999. Effects of burial, stem portion and cultivar on the decomposition of canola straw. Can. J. Plant Sci. 79: 97-100. Buried canola straw underwent 1.6 to 2 times as much decomposition as straw on the soil surface. Decomposition of Brassica napus L. was slightly less than that of B. rapa L. and cultivar effects were small in one year and insignificant in the other. Because treatment effects varied between stems and roots, plant portion likely should be considered in decomposition studies.Key words: canola, straw decomposition, burial, cultivars Blenis, P.

L'enfouissement des fanes de colza canola a augmenté de 1,6 à 2 fois leur décomposition par rapport à celle des fanes laissées à la surface du sol. La décomposition de Brassica napus L. était légèrement inférieure à celle de B. rapa L., cependant que l'effet cultivar était léger une année mais insignifiant l'autre année. Étant donné la variation des effets des traitements observée selon qu'il s'agissait des tiges ou des racines, les recherches sur la décomposition devraient tenir compte des différentes portions des plantes.
