Nitrogen Recovery from a Soil Profile by Bromus inermis1

Abstract

Abstract

Nitrogen recovery was estimated as a function of depth of placement and time from nitrate fertilizer placed at various depths in brome grass (Bromus inermis, Leyss) sod at the beginning of spring growth. The soil was a Crete silty clay loam with a clay B horizon which severely restricted root penetration. About 43% of the N placed in the C horizon (105 cm) was recovered hi two growing seasons. Per unit mass, roots hi the C horizon took up over 300 tunes more N than did roots in the surface soil. Total N in the grass reached a maximum then declined rapidly as the plants matured.
