“…11). In these experiments, three different substrates were tested and in some cases a positive response was obtained when using an organic substrate to fertilize the soil (Gobbi et al, 2016;Camacho Barboza et al, 2014). Comparisons were between an unfertilized control (T0), a totally mineral treatment (TMIN), a treatment called T50 in which 50% of crop nitrogen requirement was supplied by organic amendment and the remaining requirements with a mineral fertilizer, and a treatment called T100 in which 100% of nitrogen requirements of the crop were supplied by organic amendment.…”

Techno humus systems correspond to man-made topsoils under prominent man influence. They may be purposely\ud conceived for supporting agricultural activities or dumping of waste products, sometimes abandoned to\ud an unknown evolution. Both categories needed a more scientific frame. This is the reason we classified them as\ud morpho-functional humus systems. Improving agricultural soils with organic waste products is an ancestral\ud practice. We present four examples of techno humus systems purposely created for supporting plant growth.\ud Considering a simple home-made composting pile, we give a few basic notions about the biological functioning\ud of these artificial humus systems. Humipedon functioning and structuration are similar to those observed in\ud natural humus systems. Using even animal manure, we illustrate how to manage larger compost piles of waste\ud for application in farming areas. Composting waste that contains animal proteins needs a more careful measurement\ud of the temperature of the pile and a longer period of elevated temperature in the core of the pile.\ud Mulching of pruning residues is presented in a large urban context. The use of mulch must take into account\ud quality and composition of woody material. The lack of nutrients in some residues has to be compensated by a\ud moderate use of appropriate mineral fertilizers. Municipal solid waste, anaerobic digestion residues (grape remains)\ud and spent mushroom compost, eventually mixed with mineral fertilizers, have been tested in horticulture.\ud Benefits and drawbacks are listed for each experiment, with the evolution of carbon storage along 8\ud years of horticultural practice. Finally, we present an example of “dump” humus system. Mine tailing wastes\ud represent a huge problem in many countries. Pointing on their microbial activity, we show that they must be\ud seen as manageable living humipedons, not as piles of inert rocky material

“…To maintain or increase optimum soil fertility, one possible practice is maintenance of the humic acid content by recycling plant and algal matter, or by adding outside sources of decomposed plant or algal matter such as composts, mulch, peat, or lignite coals [2]. In this scenario, fertilization with organic matter represents an alternative for the sustainability of agro-ecosystems [3][4][5] even though its environmental impact should also be carefully evaluated [6]. Organic matter composting is one of the best-known and well-established processes that allow the stabilization and sanitation of organic wastes through accelerated aerobic decomposition under controlled conditions.…”

A three-year study was conducted to test the fertilization properties of different types of compost as the total or partial mineral nitrogen fertilization substitute in an herbaceous crop succession (Zea mays L., Triticum aestivum L. and Helianthus annus L.). Four types of compost (i. green cuttings and depuration sludge, ii. green cuttings, organic fraction of municipal wastes and other organic materials, iii. green cuttings, iv. green cuttings and organic fraction of municipal wastes) and eight fertilization treatments (combining: unfertilized control, 100% mineral fertilization, 100% compost, and 50% compost +50% mineral fertilization) were evaluated in terms of: (i) crop yields and nitrogen uptake, (ii) soil organic carbon and nitrate nitrogen soil contents variation, and (iii) residual nitrate nitrogen leached at the end of the experiment. Maize grain yield ranged from 5.2 ± 1.0 Mg ha−1 to 7.4 ± 0.7 Mg ha−1 with the highest value in the mineral fertilization treatment and the lowest values in the 100% compost fertilization. Wheat and sunflower grain yields were not significantly different among control, mineral, compost, or mineral/compost fertilization treatments with average values of 5.1 ± 0.7 Mg ha−1 and 2.3 ± 0.3 Mg ha−1, respectively. Cumulative crop yield at the end of the three years was not affected by the compost type, but was affected by fertilization treatment (highest values with mineral and 50% compost +50% mineral fertilization). The compost application did not highlight a relevant effect on soil organic carbon. Under 100% of compost fertilization, the crops did not take up a large amount of the N supplied, but it did not generate an increase of NO3-N leaching in the percolation water. Obtained results show the good fertilization properties of compost whereas the amendment property was not relevant, probably due to the low rates applied and the short experimental period.
