Modeling the effects of farming management practices on soil organic carbon stock at a county-regional scale

Soil organic carbon stock on the Majorca Island: Temporal change in agricultural soil over the last 10 years

“…The drop observed in SOC levels in annual crops could be attributed to the typical intensive soil management of these zones. The use of intensive tillage has been associated with SOC losses due to the boost of C decomposition after tillage operations (Chen et al, 2018;Morell et al, 2011). Tillage breaks up soil aggregates, which favours the release of aggregate-associated C occluded within soil aggregates (Plaza-Bonilla et al, 2013).…”

Modeling the effects of farming management practices on soil organic carbon stock under two tillage practices in a semi-arid region, Morocco

“…(2008) attributed an increase in SOC stock with application of 1000 kg/ha of organic fertilizer, and elevating crop residue rate returned at surface after harvest from the baseline by 30%, 50% and, 80%. Moreover; Chen et al. (2018) showed that higher manure C and litter C input according to the initial manure application or crop residue used, respectively, led to the higher simulated SOC stock.…”

Can Animal Manure Be Used to Increase Soil Organic Carbon Stocks in the Mediterranean as a Mitigation Climate Change Strategy?

“…It is true that soil is a very important carbon sink, but the application of 4x1000 must be accomplished according to new integrated models of agriculture, in which sources and sinks of carbon will be closed. The method of transferring manure needs to be combined with other strategies, such as those cited in Section 2 (Related work) [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]: cover crops, crop rotation, reduced tillage, crop residue incorporation to the soil, among others.…”

“…Several studies reported agricultural management practices that are found to be beneficial to sequester carbon from various regions in the world (see the literature review and listed sequestration rates in [8]. Addition of organic amendments to the soil is one of the more reported management practices to increase SOC, along with other agricultural practices [14][15][16][17][18] such us reduced tillage [19][20], crop residue incorporation [20][21][22], cover crops [23][24], crop rotation [20], [25] or land use changes [26][27][28]. Moreover, organic farming [4], [29][30][31] and conservation agriculture [32] are reported to effectively promote carbon sequestration when compared to conventional agriculture.…”
