“…The soil biochemical environment is less oxidizing and due to a more continuous supply of organic materials to soil microorganisms, there is an increase in soil enzymatic activities. We observed higher cellulose (68% more) and xylanase (35% more) activities were found in zero tilled soils which supports the findings of previous workers . The increased soil enzymatic activities were observed under ZT soils may be due to a more continuous supply of organic materials to soil microorganisms and the absence of tillage .…”

“…Mangalassery et al reported as 9% increase in soil C content after 7 years of ZT application. This enhanced C content in zero tilled soil has been attributed to the retention of crop residues at the surface and root biomass in the subsurface layers and lower decomposition rates of the rice residues which also supports our experimental findings. As compared with conventional tillage, zero tillage results in the minimum application of tillage operations which results in a decrease in external interruption.…”

“…Higher cellulase and xylanase activities were found in zero tilled soils, in similar with findings of previous workers . Zero tilled soils due to the lack of interruption, the soil biochemical environment is less oxidizing than in tilled soil , which may result in a more stable pool of extracellular enzymes .…”

The diversity of cellulolytic bacteria from the rice-pulse system can be sourced for identification of efficient cellulose decomposing microbial strains. In the present study, the abundance, structural diversity, and cellulolytic potential of the culturable bacterial community were studied in 5-year old rice-pulse system under different resource conservation technologies. Higher cellulose (68% more) and xylanase (35% more) activities were observed under zero tilled soil. The populations of cellulolytic bacteria were significantly higher (44%) in zero tillage (ZT) treatment than those of conventional practice. Results revealed that the cellulolytic bacterial diversity was found to be significantly higher under ZT practice, but the present population may not be sufficient for effective recycling of organic wastes in this system. Out of 290 bacterial isolates, 20 isolates had significantly higher cellulolytic activities, of which the top three superior isolates were received from ZT practice.The cellulolytic bacterial diversity based on 16S rDNA sequencing data revealed that the Firmicutes was the most dominant phyla and the Bacillus spp. were the common genus, the observation also showed that there were 17 different haplotypes were recorded among 20 isolates of cellulolytic bacteria. The present findings indicated that long-term ZT in the rice-pulse system could be a unique source for efficient cellulose decomposing bacteria and further the efficient bacterial strains isolated from this system can be used as efficient bioinoculants for in situ as well as ex-situ decomposition of rice straw particularly in conservation agriculture.

Predictors of Drought in Inland Valley Landscapes and Enabling Factors for Rice Farmers’ Mitigation Measures in the Sudan-Sahel Zone

et al. 2018

Drought is a noteworthy cause of low agricultural profitability and of crop production vulnerability, yet in numerous countries of Africa little to no consideration has been paid to readiness for drought calamity, particularly to spatial evaluation and indicators of drought occurrence. In this study, biophysical and socio-economic data, farmers’ community surveys and secondary data from remote sensing on soil characteristics and water demand were used to evaluate the predictors of drought in inland valley rice-based production systems and the factors affecting farmers’ mitigation measures. The study intervened in three West African countries located in the Sudan-Sahel zone, viz. Burkina Faso, Mali and Nigeria. Significant drying trends occurred at latitudes below 11°30′ whilst significant wetting trends were discerned at latitude above 11°30′. Droughts were more frequent and had their longest duration in the states of Niger and Kaduna located in Nigeria and in western Burkina Faso during the period 1995–2014. Among 21 candidate predictors, average annual standardized precipitation evapotranspiration index and duration of groundwater availability were the most important predictors of drought occurrence in inland valleys rice based-production systems. Land ownership and gender affected the commitment of rice farmers to use any mitigation measure against drought. Drought studies in inland valleys should include climatic water balance and groundwater data. Securing property rights and focusing on women’s association would improve farmers’ resilience and advance drought mitigation measures.

“…While the mineralization of the rocks of the Buem formation is dominated by plagioclases of sodium, calcite, titanium and iron oxide[16], the formations of Atacora, according to[19], are dominated by quartz, muscovite and chlorite. And the basement s.s formations are dominated by plagioclases, quartz and muscovite.Secondly, HCO 3 evolution to Cl-NO 3 point out the anthropogenic influence on groundwater by the intensive use of chemical fertilizers in agriculture by[41].…”
