“…As a result, rice straw incorporation performed better due to effective synchronization of nutrient release with crop demand. Organic residues decreased pH in post harvest soil due to the production of organic acid, phenolic and carboxylic compounds and secretion of growing biomass (Rezig et al, 2013). It may be concluded that higher dose of organic material in combination with chemical fertilizers especially nitrogen supplied significant amount of plant nutrients during crop production and increased organic carbon content in soil.…”

An experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh, Bangladesh during 2010-2011 to find out the effect of different water and organic residue levels on rice production and soil organic carbon content. Organic carbon rates from rice straw (0.5, 1.0, 1.5 and 2.0 t C ha -1 including control) were evaluated under alternate wetting and drying (AWD) and continuous flooding (CF) systems. Each treatment also received the recommended dose of chemical fertilizers excluding control. Factorial experiment was laid out in a complete randomized design with three replications. Results revealed that, maximum plant height, filled grains per tiller, 1000 grains weight, grain and straw yield were also observed in continuous flooding system in combination with 2.0 t C ha -1 in 2010 and 2011, respectively. Combined use of chemical fertilizers, 2.0 t C ha -1 fresh rice straw and continuous flooding system performed better results to reduce CO 2 -C gas emission, increased organic carbon and rice production with maintaining optimum soil pH level. Continuous flooding with 2.0 t C ha -1 as fresh rice straw is an effective way to reduce CO 2 -C emission, optimize soil pH and contribute to sustainable rice production for food security.

“…A favourable effect of the SF OA and the combined treatment on decreasing the soil EC might be due to the improvement in the porosity and infiltration rate, which could have resulted in enhanced salt leaching (Yadav et al ., ) in 2 years. The higher increase in organic C content of soil upon T 4 might have been due to more root biomass and root exudates in the belowground root zone soil (Rezig et al , ). Applying chemical fertilizers with the organic amendment has resulted in increased fertilizer use efficiency in wheat compared with chemical fertilizers alone (Yaduvanshi & Swarup, ).…”

A novel bioaugmented organic amendment (SF OA ) [consisted of vermicompost (pre-enriched with plant growth promoting fungi) mixed with pressmud and Azadirachta indica (A. Juss.) seed cake] was developed to reclaim sodic soil and support wheat production. A field trial of the SF OA application with/without chemical fertilizers conducted in completely randomized design with four replications to compare growth, yield and seed protein contents of wheat (Triticum aestivum L.) on sodic soil. The favourable changes occurred in different properties of amended soils were studied. A combined application of chemical fertilizer and SF OA significantly (p < 0·05) increased the number of spikelet per plant (63%) and weight of grains per ear (65%) in the amended soil compared with the control. Likewise, the grain yield, weight of 1000 grains and seed protein contents of wheat were significantly (p < 0·05) increased in the combined application compared with other treatments. The expression of protein bands with molecular weights of 36, 52 and 66 kDa were higher in seeds of wheat under the combined treatment. The improvement in wheat production was attributed to significant favourable changes in different soil characteristics such as bulk density, total organic C, alkaline phosphatase, β-glucosidase, dehydrogenase and cellulase activities that were increased by 234%, 181%, 234%, 176%, 189% and 150%, respectively, in case of amended soil under the combined treatment compared with the control. The tested SF OA may be recommended as soil amendment for reclaiming sodic soil and supporting wheat cultivation with better crop growth and yield in combination with chemical fertilizers on sodic soil.

“…This practice is important in sand dune soils where poor properties are a serious constraint for agriculture and food production. The organic fraction in organic amendments can enhance significantly soil aggregation, water infiltration, microbial activity, structure, and water-holding capacity particularly in soils of arid and semiarid regions, and it can reduce soil compaction and erosion (Rezig et al 2013;Angin and Yaganoglu 2011;Gilley and Risse 2000;Haynes and Naidu 1998). Chemical properties such as cation exchange capacity, organic carbon, and soil pH may also be improved by organic amendments application (Rezig et al 2013;Ogunwole et al 2010;Kumar and Goh 2000;Tisdale et al 1993).…”

Background Poor physical and chemical properties of sand dune soil are the main constrains in afforestation of sand dune in desertified area. The aim of this study is to improve the physical and chemical properties of dune soil in Elrawakeeb Dry Land Station using organic wastes as a fertilizer source and amendments, for sustainable sand dune stabilization program. Salvadora persica L. seedlings were transplanted in a 2 m 9 2 m plots and treated with: sawdust (SW), chicken manure (CH), chicken manure with sawdust (CH ? SW), sawdust with inorganic fertilizer (SW ? IF), sewage sludge (SS), sewage sludge with sawdust (SS ? SW), and control (C). The treatments were arranged in a randomized complete block design with four replicates. The soil chemical properties were determined from soil samples collected from the fixed sand dune (0-20 cm depth) in the second year after application. Results Application of organic amendments significantly (P = 0.001) increased soil organic carbon by 224 %, available P by 139.9 %, total nitrogen by 142.9 %, and mineral nitrogen by 83.5 % and decreased soil pH by 5.6 %. Conclusions Incorporation of organic waste in desertified sandy dune soils increased its nutrient content and hence sustained biological fixation of sand dunes.
