HUMUS CONTENT AND HUMUS FRACTIONS AFTER LONG-TERM SYSTEMIC MINERAL AND ORGANIC-MINERAL FERTILIZATION ON MOLLIC FLUVISOLS

2012
The present work studies the effect of long-term systemic mineral and organic-mineral fertilization on the humus amount, humus type and humus fractions on Mollic fluvisols in Plovdiv region. Fertilizer norms are 1) N75P30K20; 2) N25P15K0 + organic; 3) N50P0K20 and 4) Standard.

THE HUMUS CONTENT, RESERVE OF HUMUS AND BIOLOGICAL ACTIVITY OF PLANOSOLS FROM PRIMORSKII REGION UNDER THE PHYTOMELIORATIVE EXPERIMENT

Плодородие
Исследовано влияние посевов многолетних трав и их травосмесей с бобовыми культурами на формирование и запасы гумуса, обогащенность каталазой, эмиссию СО2 и потенциальную скорость минерализации органического вещества в агротемногумусовых подбелах Приморья. В работе использованы общепринятые в почвоведении методы.

Effect of sideral fertilizer on the content of humus in the soil

Агрохимия
In a long-term experiment, which was laid down in 1971, in 2 bookmarks with an interval of one year, the effect of sideral fertilizer on the humus content in the soil during 6 rotations of an 8-field crop rotation was studied. The soil is sod-medium-podzolic medium loam on a cover red-brown heavy loam with agrochemical indicators of the arable layer ...

Assessment of clay and humus content in soils using the dielectric method

Почвоведение / Eurasian Soil Science
The paper presents the results of measuring the content of clay, humus, and complex permittivity of 23 soil samples in the frequency range from 10 kHz to 8–10 GHz at different moisture. The content of clay (particles smaller than 0.01 mm) in the samples varied from 1.7 to 47.5%, the humus content – from 0.7 to 8%. The processes of dielectric relaxation
