“…In the present work, the rice plants responded to all sorts of organic amendments across different growth periods. Murphy et al (2016) emphasized that crop residue retention although enhanced soil properties, but did not significantly increased the total biomass of crop. The reason for the varied crop growth response to residue incorporation in soil could, therefore, be attributed to the chemical composition of the residue which determines its decomposability and (Rousk et al 2010).…”

“…Even different organic forms of compost impart distinct soil quality characteristics based on either particle size or composting methods adopted, such as reported by authors in compost prepared from pig slurry incorporated with saw dust, wood chips, and wheat straw (Romano et al 2014;Pampuro et al 2016). Crop residue retention along with conventional tillage proved to be a promising option to reduce nutrient loss in the study of Murphy et al (2016) in small holder maize system. A study in the lines with similar objective of the present investigation compared dairy manure with hardwood biochar and outlined contrasting results on microbial communities and enzyme activities of the soil (Elzobair et al 2016).…”

Purpose Intensive agriculture activities in small holder farming systems are declining over all soil nutrient status. The present study is conducted to compare the soil health and plant growth attributes under rice cultivation among different organic amendments. Recycled waste of rice-wheat agrosystem is utilized to determine optimal sustainable solution for hilly areas. Methods Randomly blocked design experiment was conducted with rice plants, each amended with organic inputs including rice straw residue (T1), rice biochar (T2), rice compost (T3), wheat straw residue (T4), wheat biochar (T5), wheat compost (T6), mix of wheat + rice compost (T7), green manure (T8) and control (no amendment). Soil samples were studied at each growth phase while plant growth attributes were measured at the harvesting stage of the crop. Results T6 and T7 have shown significantly higher magnitude of soil organic carbon, microbial biomass carbon, microbial quotient, available nitrogen, and enzymatic activities (dehydrogenase, alkaline phosphatase and urease) than biochar (T2 and T5) and crop residue amendments (T1, T4 and T8). An increase of up to 47% was obtained in cumulative growth attributes (plant height, total biomass, and a number of tillers, spikes, and spike length) of rice plant in T6 amendment. The principal component analysis revealed two components responsible for 54.17% of the variance in the organically treated soil. Conclusion The experimental results imply that composting of crop residues could be the most reliable practice to improve soil nutritional quality as well as crop growth for sustainable rice-wheat cropping system in the hilly area.

“…It is well established that many of these parameters are likely to change with tillage regime and crop residue management as reported by a large body of literature (e.g., Six et al, 1999; Lipiec et al, 2006; D’Haene et al, 2008; Murphy et al, 2016), which in return may influence soil microbial communities and the ecosystem services they provide.…”

Temporal Dynamics of Soil Microbial Communities below the Seedbed under Two Contrasting Tillage Regimes

Agricultural productivity relies on a wide range of ecosystem services provided by the soil biota. Plowing is a fundamental component of conventional farming, but longterm detrimental effects such as soil erosion and loss of soil organic matter have been recognized. Moving towards more sustainable management practices such as reduced tillage or crop residue retention can reduce these detrimental effects, but will also influence structure and function of the soil microbiota with direct consequences for the associated ecosystem services. Although there is increasing evidence that different tillage regimes alter the soil microbiome, we have a limited understanding of the temporal dynamics of these effects. Here, we used high-throughput sequencing of bacterial and fungal ribosomal markers to explore changes in soil microbial community structure under two contrasting tillage regimes (conventional and reduced tillage) either with or without crop residue retention. Soil samples were collected over the growing season of two crops (Vicia faba and Triticum aestivum) below the seedbed (15-20 cm). Tillage, crop and growing stage were significant determinants of microbial community structure, but the impact of tillage showed only moderate temporal dependency. Whereas the tillage effect on soil bacteria showed some temporal dependency and became less strong at later growing stages, the tillage effect on soil fungi was more consistent over time. Crop residue retention had only a minor influence on the community. Six years after the conversion from conventional to reduced tillage, soil moisture contents and nutrient levels were significantly lower under reduced than under conventional tillage. These changes in edaphic properties were related to specific shifts in microbial community structure. Notably, bacterial groups featuring copiotrophic lifestyles or potentially carrying the ability to degrade more recalcitrant compounds were favored under conventional tillage, whereas taxa featuring more oligotrophic lifestyles were more abundant under reduced tillage. Our study found that, under the specific edaphic and climatic context of central Belgium, different tillage regimes created different ecological niches that select for different microbial lifestyles with potential consequences for the ecosystem services provided to the plants and their environment.

“…Awopegba et al (2017) suggested that the herbaceous mulches increased soil organic carbon, TN, and exchangeable cations more significantly. Eventually, the enhancement of soil fertility by the application of organic mulches along with crop residue retention in farms can improve soil functions and enhance nutrient use efficiency by recycling them through soils (Murphy et al, 2016;Mwango et al, 2016). For Season II, the mulches under the upland regime for taro cultivation could increase all of the soil properties.…”

Taro (Colocasia esculenta L. Schott) is an important food staple in developing countries in Africa, West Indies, the Pacific region, and Southeast Asia. Because taro can be grown in almost all tropical regions of the world, it will play a crucial role in food security. The use of organic mulches, which contribute to soil water management, weed control, and fertilization simultaneously, shows promise as an eco-friendly approach in agronomy. In the present study, a field experiment including two cropping seasons (I and II) was conducted to evaluate the effects of water regimes with organic mulching on the taro growth and corm nutritive values. In results, compared with that under the upland regime, taro cultivation under the flooding regime had a higher level of soil fertility and better weed control. The flooding regime promoted more the taro plant growth and further enhanced the yields of the harvested corms; also, sugarcane bagasse and rice husk would be the superior mulch to obtain better corm attributes. By contrast, cultivation under the upland regime enhanced the nutritive values of taro corm more than did that under the flooding regime. Regardless of the upland or flooded regime, mulching treatments with rice husk could enrich taro corm nutrition more than could those with sugarcane bagasse and peanut hull. Also, the effects of water regime and mulching on taro plant growth and corm attributes would be varied with the rainfalls during the period of vegetative growth.
