“…Soil microorganisms played an important role in balancing the decomposition and accumulation of SOC because microbial products were important components of SOC (Miltner et al, 2011). The application of organic fertilizers significantly increased the microbial biomass, microbial biodiversity, and soil enzymatic activity compared with chemical fertilization alone in the rice-wheat cropping system (Zhao et al, 2016), which may be somewhat responsible for the relatively labile SOC in soil amended with organic fertilizers. The SCMR increased with increasing soil depth, indicating that SOC in the deep soil layer (20-40 cm) may be more susceptible to decomposition than that in the surface layer (0-20 cm) when exposed to air.…”

“…This is consistent with the findings of Zhou et al (2009), who reported that the application of organic fertilizers in paddy soils of south China increased the Feo concentration compared with chemical fertilization alone. Organic fertilization directly increased the CMR by improving the growth and activity of soil microorganisms (Zhao et al, 2016), resulting in a larger reductive dissolution of Fe oxides in the rice phase than chemical fertilization alone because of a greater demand for alternative electron acceptors Kögel-Knabner et al, 2010). The repeated redox alternations could drive the biogeochemical cycles of iron oxides and organic matter (Ginn et al, 2017;Riedel et al, 2013), during which organic fertilization promoted the formation of SRO minerals by forming organo-SRO complexes to prevent their growth or transformation to the crystalline forms (Schwertmann, 1966;Schwertmann et al, 2005;Yu et al, 2017).…”

S oil organic carbon constitutes the largest terrestrial C reservoir in the global C cycle (Heimann and Reichstein, 2008). The long-term storage and stability of SOC have a profound influence on soil fertility enhancement, food security improvement, and global warming mitigation (Lal, 2004). Furthermore, SOC is closely associated with a wide range of soil biogeochemistries and thus plays an important role in improving soil quality and agro-ecosystem productivity (Reeves, 1997). Therefore, C sequestration in agricultural soils by increasing organic amendment inputs has long been considered an important issue in increasing the SOC content and the mechanisms underlying the accumulation of SOC have drawn increasing attention Wen et al., 2014 • Oxalate extractable iron oxides contributed to soil organic carbon sequestration.• Soil organic carbon from 20 to 40 cm was more labile than that from 0 to 20 cm.• Oxalate extractable iron oxides preferentially preserved aromatic compounds.

“…The literature on NUE tends to focus on CF or inorganic/organic fertilization, rather than OF [26,31,32]. Application of organic-inorganic compound fertilizer was previously found to have a positive effect on soil organic carbon accumulation and crop productivity in rice fields, reducing chemical fertilizer use, optimizing the physical qualities of paddy soil, and improving long-term sustainability through increased N efficiency, possibly as a result of enhanced microbial activity [31][32][33].…”

Despite the growing demand for organic products, research on organic farming (OF) such as genotype screening, fertilizer application and nutrition uptake remains limited. This study focused on comparisons of the apparent recovery efficiency of nitrogen fertilizer (REN) in rice grown under OF and conventional farming (CF). Thirty-two representative conventional Japonica rice varieties were field grown under five different treatments: control check (CK); organic farming with low, medium and high levels of organic fertilizer (LO, MO and HO, respectively); and CF. Comparisons of REN between OF and CF classified the 32 genotypes into four types: high REN under both OF and CF (type-A); high REN under OF and low REN under CF (type-B); low REN under OF and high REN under CF (type-C); and low REN under both OF and CF (type-D). Though the yield and REN of all the rice varieties were higher with CF than with OF, organic N efficient type-A and B were able to maintain relatively high grain yield under OF. Physiological activities in flag leaves of the four types from booting to maturity were subsequently investigated under OF and CF. Under OF, high values of soil and plant analyzer development (SPAD) and N were observed in type-B varieties, while in contrast, both indexes slowly decreased in type-C varieties under CF. Moreover, the decline in N content in type-C and D varieties was greater under OF than CF. The decrease in glutamine synthetase (GS), glutamic-pyruvic transaminase (GPT) and glutamic oxaloacetic transaminase (GOT) activity in flag leaves was smaller under OF than CF in type-A and B varieties, while in contrast, type-C and D varieties showed an opposite trend. The findings suggest that OF slows the decline in key enzymes of N metabolism in organic N-efficient type rice, thus maintaining a relatively high capacity for N uptake and utilization and increasing yield during the late growth period. Accordingly, we were able to screen for varieties of rice with synergistically high REN and high grain yield under OF.

Soil fertility decline is considered as one of the major causes for resulting in reduced yield of potato production in abelo area Masha district sheka zone of south-western Ethiopia. Hence, a field experiment was conducted in Belgand Meher season, in abelo area, Masha district south-western Ethiopia, to investigate the effect of combined use of application of Cattle Manure (CM) with mineral NP on growth, biomass yield, quality, of potato tuber. The treatments comprised combinations of three rates (2.5,5, 7.5t ha -1 ) of CM with 25%, 50% and 75% of recommended rates of mineral NP, respectively. In addition, 100% recommended rate of mineral NP for the experimental site (165 kg N ha -1 and 137 kg P 2 O 5 ha -1) and zero rates were used for comparison. The experiment was laid out in a randomized complete block design with three replications.The results revealed that applying 7.5 t ha -1 CM combined with 75% mineral NP gave significantly Days to 50% flowering by 7 daysi.e. From 56-6 and14 daysi.e. from 51-65, days to 50% maturity by 5 daysi.e. from (101-106) and 13 days from (95-108) and increases plant height from 56-69 and 63-78, Increase shoot fresh weight by 39.66% from (1274.59-1780.2 ghill ),increased dry matter content from (21.085-25.782) and (22.36 to 24.47), specific gravity from (1.083-1.107) and (1.092 -1.101) reduces small tuber size percentage ) and improves medium size tubers from (65.56 to 74.79) and (44.58 to 80.26) in Belg and Meher season as compared to zero application. Respectively. Therefore, it can be concluded that, the use of combined application of CM (7.5 t ha ) can significantly increases growth, biomass yield, improvement in tuber quality.
