Humusica 2, article 19: Techno humus systems and global change - Conservation agriculture and 4/1000 proposal
2018
International audience; Philosophy can overlap pedology. It is not casual that life begins and finishes in the soil. We separated the concepts of Humipedon, Copedon and Lithopedon. Some sections were dedicated to the founders of the movement for a new type of agriculture (agroecology). They simply proclaim to accompany the process of natural evolution instead of spending a lot of energy in hunting competitor organisms with pesticides or boosting the soil with mineral fertilisation and tillage. The core of the article is built on a biological concept of the soil and shows researches supporting this view. After pointing to the soil structure and illustrating its natural genesis, explaining wh…
Soil aggregates and humus systems
2016
The European Society for Soil Conservation Conference, organized by the Babes-Bolyai University will take place from 15th June to the 18th June 2016 at the Babes-Bolyai University of Cluj-Napoca in Cluj-Napoca, Romania. The conference will cover areas like Soils – Our Common Future” stresses the vital interconnection between soil and life, as well as its importance for the future of the human society.; International audience; The survey of few main morphological soil aggregates (with intrinsic biological, chemical and physical contents) reveals the existence of different humus systems. Recognizable by naked eyes in the field, each humus system is confined in an ecological frame (climate, ve…
Long-term cropping systems and tillage management effects on soil organic carbon stocks and steady state level of C sequestration rates in a semiarid…

A calcareous and clayey xeric Chromic Haploxerept of a long-term experimental site in Sicily (Italy) was sampled (0–15 cm depth) under different land use management and cropping systems (CSs) to study their effect on soil aggregate stability and organic carbon (SOC). The experimental site had three tillage managements (no till [NT], dual-layer [DL] and conventional tillage [CT]) and two CSs (durum wheat monocropping [W] and durum wheat/faba bean rotation [WB]). The annually sequestered SOC with W was 2·75-times higher than with WB. SOC concentrations were also higher. Both NT and CT management systems were the most effective in SOC sequestration whereas with DL system no C was sequestered. …
