Long Run

In South Asia, soil health degradation is affecting the sustainability of the rice-wheat cropping system (RWCS). Indeed, for the sustainability of the soil quality, new adaptive technologies, i.e., conservation tillage and straw management resource conservation, are promising options. This investigation was focused on the interaction of tillage and straw management practices and their effects on Aridisols, Yermosols soil quality, and nutrients dynamics with different soil profiles within RWCS. The long-term field experiment was started in 2014 with the scenarios (i) conventional tillage (SC1), (ii) residue incorporation (SC2), (iii) straw management practices (SC3 and SC4) and conservation tillage (SC5). Conservation tillage practice (SC5) showed significant impact on properties of soil and availability of nutrients in comparison with that of conventional farmers practice (SC1) at the studied soil depths. The SC5 showed significant results of gravitational water contents (25.34%), moderate pH (7.4), soil organic-matter (7.6 g kg−1), total nitrogen (0.38 g kg−1), available phosphate (7.4 mg kg−1), available potassium (208 mg kg−1) compared to SC1 treatment at 0 to 15 cm soil depth. Whereas, DTPA-extractable-Cu, Mn, and Zn concentration were significantly higher, i.e., 1.12 mg kg−1, 2.14 mg kg−1, and 4.35 mg kg−1, respectively under SC5 than conventional farmer’s practices, while DTPA (diethylene triamine pentaacetic acid) extractable Fe (6.15 mg kg−1) was more in straw management practices (SC4) than conventional and conservation tillage. Therefore, conservation tillage (SC5) can surge the sustainability of the region by improving soil assets and nutrients accessibility and has the potential to minimize inorganic fertilizers input in the long run.

An experiment was conducted in the rainfed Inceptisols of Rakhdhiansar in Kandi areas of Western Himalayas of South Kashmir and Kumaon, India for four years to assess the influence of combined use of tillage and nutrient management treatments on soil quality under maize based cropping system. The experiment was initiated in a split plot design with three main and three sub-treatments using maize (Kanchan-510) as the test crop. The main experimental treatments were: T1: Conventional Tillage (CT) +Two Intercultures (Two IC), T2: Low Tillage (LT) +Two Intercultures (Two IC) and T3: Low Tillage (LT) + Weedicide + One Interculture (One IC). The three sub treatments were, T1: 100% N through organic sources (compost), T2: 50% N through organic sources + 50% N through inorganic sources and T3: 100% N through inorganic sources. The results of the present study clearly revealed that the tillage treatments did not significantly influence most of the soil quality parameters except available S, microbial biomass carbon (MBC) and Mean weight Diameter of Soil Aggregates (MWD). When averaged over nutrient levels, among the tillage practices, conventional tillage + Two IC recorded the highest available S of 20.87 kg ha-1. However, sub-sub treatments viz nutrient management significantly influenced the organic carbon (OC), available N, P S and boron, dehyrogenase assay (DHA), labile carbon (LC), bulk density (BD) and MWD. When averaged over tillage levels, the application of nutrients through inorganic sources recorded significantly highest available N (160.50 kg ha-1), P (30.67 kg ha-1) and K (207.87 kg ha-1 in soil. Finally, in terms of Relative Soil Quality Indices (RSQI), Low tillage + Two IC (0.87) and Low tillage + Weedicide + One IC (0.89) proved superior compared to Conventional Tillage + 2 IC (0.82). Similarly, when averaged over tillage levels, the order of performance of nutrient management treatments was:100% N through organic sources (0.93) > 50% N through organic sources + 50 % N through inorganic sources (0.84) > 100% N through inorganic sources (0.82). Though the interactions between tillage levels and nutrient management were not significant, but the combination of Low tillage practices with 100 % organic Source of nutrients was quite superior in maintaining relatively higher RSQI. Thus, the results of the present study and methodology used will be highly useful to different stake holders associated withland and soil quality management

Quantification of soil organic carbon cycling as impacted by soil and crop man- agement practices is required for C storage and soil quality improvement investi- gations. This study assessed the short-term effect of conventional tillage (CT) and No-Tillage (NT) practices on SOC sequestration and yield of cocoyam (Colocasia esculenta). The experiment was conducted simultaneously at two lo- cations (06◦52' N, 07◦15' E and 06◦ 26' N; 07◦16' E) in southeast Nigeria. A Ran- domized Complete Block Design with five replications and four treatments com- prised of CT and NT, respectively, with 150 and 300 Kg ha-1 of NPK 15:15:15, was used. Soil quality attributes were measured at two soil depths (0-20 cm and 20-40 cm) in both locations and analyzed. The results indicated that the quantity of carbon sequestered in the soil at 0-20 cm soil depth for both sites was 46.7- 90.9 and 65.0-117.9 Mg ha-1, respectively, for the two planting seasons in NT plots treated with 300 Kg ha-1 of NPK. This was followed by NT plots treated with 150 Kg ha-1 of NPK, which sequestered 55.5-86.2 and 46.7-91.9 Mg ha-1 SOC. CT plots that received 300 Kg ha-1 NPK with 11.3-47.6 Mg/ha SOC had 44% and 28% lower stored SOC when compared to NT, NPK 150 Kg ha-1 plots for the two-planting season respectively. This indicates that CT practices signifi- cantly limit SOC sequestration. CT with 300 Kg of NPK 15:15:15 gave the high- est corm yield, followed by No-till with 300 Kg ha-1. A better edaphic condition provided by CT was compensated for by higher doses of N fertilizer in NT Plots.

Paddy residues are the most generous agricultural biomass from the paddy cultivation, Paddy residues practices include crop residue amendment and in-situ burning. It indicated that residue amendment increased the organic carbon and nutrient contents in soil, However, an open residue burning is still a common practice in Thailand despite of strict law enforcements and proper education to farmers about its implications on soil, human and animal health The present study determined how residues management practices: residue amendment and stubble burning, influence the soil organic carbon by determining δ13C in paddy soil profile. The 30 cm depth soil samples from the naturally straw amendment and stubble burning paddy fields were collected in Chiang Khwan district, Roi-et province during 2017. The δ13C values with soil depth showed that residue management practices produce statistical differences in both soils. The δ13C values of soil samples from amendment and burning sites ranged from-23.19‰ to-17.98‰ and-24.79‰ to-19.28‰, respectively. Carbon isotopes differentiate clearly between amendment site (more positive values) and burning site (more negative values). The results from this study were in accordance with literatures which reported that the δ13C distribution in the soil profile can be applied to study in SOC dynamics as a result of different paddy residue management practices (amendment or burning). Further research is needed to confirm the validity of the stable carbon isotope technique in this type of studies.

Wheat Varieties

The increasing spread of conservation agriculture demands that the next generation of wheat varieties includes cultivars capable of maintaining satisfactory yields with lower inputs and under uncertain climate scenarios. On the basis of the genetic gains achieved during decades of selection oriented to yield improvements under conventional crop management, it is important that novel breeding targets are defined and addressed. Grain yield, yield-related traits, and phenological and morphological characteristics, as well as functional quality parameters have been analyzed for six varieties each of bread and durum wheat, under minimum tillage and no-tillage. During the three-year experiment, the climatic conditions at the field trial site were characterized by low rainfall, although different degrees of aridity—from moderate to severe—were experienced. Differences were found between these two soil management practices in regard to the varieties’ yield stability. A positive influence of no-tillage on traits related to grain and biomass yield was also evidenced, and some traits among the examined seemed involved in varietal adaptation to a particular non-conventional tillage system. The study also confirmed some breeding targets for improved performance of wheat genotypes in conservation agroecosystems. These traits were represented in the small set of traditional varieties analysed.

Residue Retention

A field experiment was conducted to evaluate the effect of tillage practices, residue management and cropping system on soil properties at NMRP, Rampur, Chitwan from November 2015 to April 2016. The experiment was laid on Strip split design with combination of 12 different treatments i.e, zero tillage & conventional tillage as main plot in the strip, residue retention & residue removal as sub-plot factor and maize – wheat, maize + soybean – wheat & soybean – wheat cropping system as sub-sub plot factor. Three replications of the treatments were made. Soil sample before experiment and after harvest of wheat was taken (0-15cm). The experiment showed significant effect of zero tillage on organic carbon (2.169%) and on total soil nitrogen (0.112 %). Zero tillage with retention of residues is valuable tool for the conservation agriculture and helps in sustainability of soil however long-term research for the tillage management and residue retention should be conducted to highlight the major effects on change in properties of soil.Int.

The climate of the terai region of West Bengal, India in general, is subtropical par humid to tropical with light textured acid soil with the problems like low moisture retention, low water use efficiency, leaching of bases, soil erosion, limited availability of multiple plant nutrients and restricted activity of beneficial soil micro-organisms. To combat these soil health related problems and to improve the overall productivity of North Bengal, a comparison between the conventional and conservation tillage was taken up and the immediate results were measured in terms of growth, yield attributes and yield. In the first two years of experimentation, though different growth attributes, grain yield, stover yield, and different yield attributing characters such as kernel rows cob-1, number of kernels row-1, 100 seed weight (g), number of seeds cob-1, girth of cob, length of cob and number of effective cob plant-1 were higher in conventional tillage as compared to conservation tillage but in terms of soil heath characteristics, conservation tillage had a meaningful remark from the initial years towards the future food security. Mulching @ 4 t ha-1 was found to have performed better than unmulched treatments. Application of 75% recommended dose of fertilizer + Vermicompost @ 10 t ha-1 resulted in better growth and yield attributes which directly influenced to have higher grain and stover yield.

The gradual change in management practices in sugarcane (Saccharum spp.) production from burning straw to a green harvesting system, as well as the use of minimum soil tillage during field renovation, may affect soil fertility and soil organic matter (SOM) contents. The objectives of this work were to investigate the influence of sugar cane production systems on: (1) soil fertility parameters; (2) on physical carbon fractions; (3) and on humic substance fractions, in a long-term experiment, comparing two soil tillage and two residue management systems an Xanthic Udult, in the coastal tableland region of Espírito Santo State, Brazil. The treatments consisted of plots (conventional tillage (CT) or minimum tillage (MT)) and subplots (residue burned or unburned at harvesting), with five replicates The highest values of Ca2+ + Mg2+ and total organic carbon (TOC) were observed in the MT system in all soil layers, while high values of K+ were observed in the 0.1-0.2 m layer. The CT associated with the burned residue management negatively influenced the TOC values, especially in the 0.1-0.2 and 0.2-0.4 m layers. The carbon in the humin fraction and organic matter associated with minerals were significantly different among the tillage systems; the MT showed higher values than the CT. However, there were no significant differences between the sugarcane residue management treatments. Overall, fractioning the SOM allowed for a better understanding of tillage and residue management systems effects on the soil properties.
