“…It is difficult to maintain amounts of organic carbon that might have a long-term beneficial effect due to the intensely shifting weather patterns, notably high temperatures and irregular or poor rainfall patterns [26]. While carbon is essential for soil fertility, productivity and quality, its reduction impacts the sustainability of agricultural production ecosystems and is crucial for sustaining the overall quality of the environment [27].…”

Dimapur (Nagaland, India) is dominated by undifferentiated hillside slopes and alluvial plains. The Muga and Eri silk industries are important cultural and economic activities for the inhabitants of Dimapur. Profitable silk production requires adequate quality and quantity of healthy leaves and is highly dependent on the soil fertility of the region. Keeping this in view, the present study was carried out as a first attempt to prepare a geographic information system (GIS) map for Muga and Eri soils in Dimapur, Nagaland. A total 65 surface (0–15 cm) soil samples from Muga farms and 79 surface soil samples from Eri farms were collected and analysed for soil pH, organic carbon content and availability of macro- and micronutrients. Soils of both Muga and Eri farms were found to be extremely (<3.05) to moderately (5.09–6.84) acidic. Soils of Muga and Eri farms were found to have low to high organic carbon content (from 0.24 to 1.98%), low to high available nitrogen content (179.8–612.5 kg ha−1) and medium available phosphorus content (2.68–154.6 kg ha−1). The sulphur availability index was 0.26 and 11.81 for Muga and Eri host plant farms, respectively. The multi-macronutrient map revealed that 46.95% of the district’s total geographical area (TGA) showed deficiencies in one or more macronutrients (high priority zone). Thus, these regions need urgent attention in terms of nutrient management decisions in order to reduce the declining trend of soil fertility and achieve sustainable sericulture production.

“…Geographically, it lies between 8°49'0" N and 8°43'30" N latitudes and between 38°43'00" E and 38°48'30" E Longitudes. Akaki district bounded by Ada'a district in the East, Sebeta Hawas and Kersa Malima districts in the West, LibenZukala district in the South and Addis Ababa, Ginbichu and Barak districts in the North [2,15]. The study sites were selected purposely; since the soil sample was taken from selected site categorized in to CA (10.12ha) identify activities like ( integration of acacia species distribution in farming land, crop rotation, intercropping, minimum tillage and residue retention) and the adjacent of conventional agriculture (10.12ha) where no management practices were applied and freely accessed were used.…”

Land degradation and extensive use of agricultural lands have led to the decline in soil fertility. To reverse the nutrient deterioration of cultivated lands, farmers have started employing various conservation agriculture practices. This study was initiated to examine the potential of conservation agriculture (integrated practices such as inter cropping, crop rotation, residue retention and minimum tillage) by smallholder farmers to enhance soil organic carbon stock and other selected soil physicochemical properties in Akaki district Bilbilo micro watershed. A systematic sampling method was employed for data collection. Totally 96 composite soil samples (8 plots x 2 systems x 2 replication of site x 3 depth: 0-10cm, 10-20cm and 20-30cm) were collected for analysis. Results showed that soil bulk density (BD) was significantly (p<0.05) varied with practices and depth (p<0.001). It was lower in soil under conservation (0.78 g m-3) than under conventional practice (1.48 gm-3); and in the top layer 0-10 cm (1.21±0.05) than the rest depths. BD showed increasing trend with soil depth across the practices: lower on the top 0-10cm depth (0.78 ±0.03) compared with the rest. The pH was higher (7.28) in conservation than conventional (5.75). The CEC was higher (14.6Cmol (+)/kg) in conservation practice than in the conventional (10.3 cmol (+)/kg). Both pH and CEC had shown increase in the two practices and soil depth due to the leaching of base cation from upper to lower layers. The mean SOC stocks decrease with increasing soil depth about the significant variations with treatments and depth. The SOC stock was higher (110.6t c /h) in conservation practice than in conventional practice (50.22 t/ha). Similarly, total N stocks was also higher (19.5 t c/ha) in conservation practice than in conventional practice (17.4 t c/ha). SOC and total N in both practices had decreased with soil depth due to lower accumulation of organic residue in the lower layer. Likewise, C: N ratios had increases with depth due to similar reason the decrease the amount of soil organic carbon and TN pool (e.g. root biomass) with depth. However, the C: N ratio has higher value in conservation practice (6.51) than in conventional practice (6.05). Most of the measured soil properties were improved in CA aided followed by soil depth compared with conventional agriculture and at soil depth layers ones. The interaction of farming practice types and soil depth also significantly affected all parameters.

“…Although a lot of research is being conducted to estimate carbon stock all over the world, record of carbon stock of this region is limited due to various reasons like, inaccessibility, large heterogeneity of soil etc. According to a study reported by Baruah et al (2017), the overall carbon stock for agricultural land of Jorhat district was 8.18 Tg, 14.21 Tg and 19.78 Tg for 0-30 cm, 0-60 cm and 0-90 cm, respectively.…”

Aim: To investigate soil organic carbon (SOC) storage and distribution pattern under paddy and forest land use along with the effect of various edaphic and environmental factors on it. Methodology: Soil samples from 12 different profiles were collected from different agriculture and forest lands across the district. Soil samples were collected at three different depth ranges 0?30, 30?60, and 60?100 cm from both agriculture and forest land. Soil samples were processed and analysed for different soil parameters in laboratory.? Results: Soil organic carbon density (SOCD) was found to be higher under forest at all depth range compared to agricultural land. But soil organic carbon storage was higher under agricultural land (1.34 tC at 0-100 cm depth) compared to forest (0.44 tC at 0-100 cm depth) land. Geostatistical method was used to estimate the total SOC storage and density (SOCD) of which density was found to be high under forest (1.21 kg m-2) but carbon stock was high for paddy field (1.34 t C). Zero order correlation and path analysis revealed significant effect of soil texture on SOCD over environmental factors in this region.? Interpretation: Information from this study can be also useful for identification of critical and potential regions in terms of carbon storage which may need immediate attention. This information will also be helpful for the policy makers in management and monitoring of natural resources and can act as an input for further research.
