（野菜栽培部）
完熟モミガラ牛ふん堆肥を主原料とし，窒素成分を尿素または菜種油かすの混合で成分調整したエクストルーダ型成型堆肥のキャベツ作型別施用方法について検討した結果，以下の知見を得た．
１ 牛ふん堆肥に尿素または菜種油かすを混合し，窒素成分を調整した成型堆肥は，キャベツ栽培の基肥として利用できる．
２ 成分調整をした成型堆肥をキャベツ栽培の基肥として施用しても，リンおよびカリウムの吸収量は慣行の化成体系と同等である．
３ 定植後の地温が低い時期に向かう初夏出し作型では，牛ふん堆肥に菜種油かすを混合した成型堆肥からの窒素供給は，牛ふん堆肥に尿素を混合した成型堆肥よりも緩やかである．一方，定植後の地温がまだ高い初冬出し作型では，牛ふん堆肥に菜種 油かすを混合した成型堆肥からの窒素供給は，牛ふん堆肥に尿素を混合した成型堆肥と同等である．
４ 成型堆肥を施用後の土壌中の無機態窒素の硝酸化成作用は速い．
５ 牛ふん堆肥に菜種油かすを混合した成型堆肥の肥効率は，初夏出し作型では50％，初冬出し作型では30％未満が適当である．
６ 成型堆肥の２年連用により，慣行栽培に比べてキャベツ跡地土壌の物理性，化学性が改善されるが，交換性カリウムの含量が多くなる．

As the result that it made the ripeness chaff cattle dung compost to be
a main raw material and examined the application method according to the
cabbage cropping type of extruder type molding compost which compounded
ingredients for nitrogen component in the mixing of rape oilseed meal or urea a
following knowledge it gets get.
1. The nitrogen component of the molding
compost is adjusted by mixing urea or rape oilseed meal in the cattle dung
compost, and the molding compost .As a basal fartilization of the cabbage
cultivation utilize can.
2.Equivalent with the formation system of
the practice the absorption of phosphorus and potassium, even if the molding
compost by quality governing is used as a basal fartilization of the cabbage
cultivation.
3. The nitrogen supply from molding
compost which mixed the urea in the cattle dung compost though in the early
winter broth cropping type, nitrogen supply from the molding compost in which
either cropping type also mixed rape oilseed meal in the quick. cattle dung
compost early summer broth early winter broth is rapid, in the early summer
broth cropping type, it gentle.
4. Quick the nitrification of the
inorganic nitrogen in the soil after it uses the molding compost.
5. Adequate in the early summer broth cropping
type in 50% and early winter broth cropping type fertilizer effect rate of the
molding compost which mixed the rape oilseed meal in the cattle dung compost
under 30 %.
6. Though physical condition and chemical
property of the cabbage used place soil are improved by 2 years continuous use
of the molding compost, the integration of exchangeable potassium increase.
