HUMUS BALANCE AND ITS QUALITY IN DIFFERENT FERTILIZATION SYSTEMS IN CEREAL СROP ROTATION

Abstract

Experiments were conducted at the Voke Branch of Lithuanian institute of Agriculture during 1998-2005. Results of studying the effect of different soil and crop management on the humus status of loamy sandy Haplic Luvisols were generalized. It was found that the application of different green manure species ( Lupinus luteus L., Trifolium pratense L., and Raphanus sativus L.) and straw from cereal crops ( Secale cereale, Hordeum L.) under conventional conditions helped to sustain a stable humus budget in cereal agrophytocenoses. A significant change in the fractional composition of HAs and FAs occurred under the effect of green manure. The decomposition of green manure and the formation of humic substances also depended on the hydrothermal conditions during application of manure.
