For this reason, we have carried out a thirty-two-year-old long-term trial in Kabete, Kenya. These soils were treated with organic (maize stover (MS) at 10 t ha\u22121, farmyard manure (FYM) at 10 t ha\u22121) and inorganic fertilizers 120 kg N, 52.8 kg P (N2P2), N2P2 + MS, N2P2 + FYM, a control, and a fallow for over 30 years. We examined 16S rRNA gene and 28S rRNA gene fingerprints of bacterial and fungal diversity by PCR amplification and denaturing gradient gel electrophoresis separation, respectively. The PCR bacterial community structure and diversity were negatively affected by N2P2 and were more closely related to the bacterial structure in the soils without any addition (control) than that of soils with a combination of inorganic and organic or inorganic fertilizers alone. The effect on fungal diversity by N2P2 was different than the effect on bacterial diversity since the fungal diversity was similar to that of the N2P2 + FYM and N2P2 + MS-treated. However, soils treated with organic inputs clustered away from soils amended with inorganic inputs. Organic inputs had a positive effect on both bacterial and fungal diversity with or without chemical fertilizers. Results from this study suggested that total diversity of bacterial and fungal communities was closely related to agro-ecosystem management practices and may partially explain the yield differences observed between the different treatments.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "Microbial diversity", "soil microorganisms", "engrais organique", "http://aims.fao.org/aos/agrovoc/c_27870", "Organic and inorganic amendments", "F08 - Syst\u00e8mes et modes de culture", "rendement des cultures", "630", "fertilisation", "biodiversit\u00e9", "http://aims.fao.org/aos/agrovoc/c_4592", "http://aims.fao.org/aos/agrovoc/c_36669", "http://aims.fao.org/aos/agrovoc/c_2018", "inorganic fertilizers", "http://aims.fao.org/aos/agrovoc/c_10795", "http://aims.fao.org/aos/agrovoc/c_34326", "fertility", "2.

However, rigorous empirical evidence from Southeast Asia, particularly in the Cambodian agro-ecosystem, is still scarce. We hypothesized that high and diversified biomass-C inputs in CA might be the first step toward to increase SOC in the topsoil by creating the C flow to support C storage overtime. Thus, the aim of this study was to quantify the short-term (i.e., five year) impacts of soil management and cropping systems on soil organic C (SOC), soil total N (STN), particulate organic C (POC) and mineral-associated organic C (MAOC). There were three distinct experiments comprised of a combination of cover and main crops including rice-, soybean- and cassava-based cropping systems, hereafter designated as RcCS, SbCS and CsCS, respectively. The experimental plots were laid out in a randomized complete block design with three replicates. Soil management treatments included conventional tillage (CT) and no-till (NT) and a selected adjacent area of reference vegetation (RV). Soil sampling was conducted in 2011 and 2013 at seven depths (0\u20135, 5\u201310, 10\u201320, 20\u201340, 40\u201360, 60\u201380 and 80\u2013100\u00a0cm). Soil management and crop sequences significantly affected SOC and STN stocks in all three cropping systems. On average, NT SOC stocks at 0\u20135\u00a0cm depth was greater than those of CT by 10%, 20% and 18% and STN stocks by 8%, 25% and 16% for RcCS, SbCS and CsCS, respectively. SOC levels followed the order RV\u00a0>\u00a0NT\u00a0>\u00a0CT. SOC stocks in the subsoil layers were consistently lower in NT than in CT in all three cropping systems. POC stocks at 0\u20135\u00a0cm depth in NT were on average 22%, 20% and 78% greater than those in CT in RcCS, SbCS and CsCS, respectively. However, significant differences were detected only in RcCS and CsCS. The major POC stocks were found at 0\u201320\u00a0cm depth. NT treatments in SbCS stored 9% greater MAOC stocks at 0\u20135\u00a0cm depth than those in CT, and an increasing trend of NT was observed in RcCS and CsCS. In all three cropping systems, NT systems with diversified crop species significantly increased SOC stocks ranging by 6 to 28% and POC stocks by 56\u2013127% in the surface soils and tended to restore SOC and POC in the subsoil layers after five years. The results leads to accept the hypothesis that short-term CA associated with high biomass-C inputs (particularly bi-annual rotations) promotes SOC recovery in the topsoil layer and creates a potential to increase SOC in the subsoil layers when deep-rooting cover crops are included in crop rotations.", "keywords": ["P33 - Chimie et physique du sol", "cycle du carbone", "sol", "Glycine max", "Manihot esculenta", "F08 - Syst\u00e8mes et modes de culture", "teneur en mati\u00e8re organique", "agro\u00e9cologie", "Oryza sativa", "01 natural sciences", "utilisation des terres", "agriculture alternative", "http://aims.fao.org/aos/agrovoc/c_5388", "http://aims.fao.org/aos/agrovoc/c_33990", "teneur en azote", "http://aims.fao.org/aos/agrovoc/c_4073", "biomasse", "http://aims.fao.org/aos/agrovoc/c_36669", "http://aims.fao.org/aos/agrovoc/c_4579", "savane", "syst\u00e8me de culture", "http://aims.fao.org/aos/agrovoc/c_3301", "http://aims.fao.org/aos/agrovoc/c_8511", "http://aims.fao.org/aos/agrovoc/c_35657", "0105 earth and related environmental sciences", "2.

We synthesize recent research developments in soil nitrogen biogeochemistry into an aspirational and accessible microbe-centered framework that clarifies understanding of nitrogen accumulation, recycling, and plant uptake processes in soil.
