Labile organic carbon (LOC) fractions are considered as sensitive indicators of change in soil quality and can serve as proxies for soil organic carbon (SOC). Although the impact of tillage, crop rotation and crop residue management on soil quality is well known, less is known about LOC and SOC dynamics in the sweet sorghum production systems in South Africa. This short-term study tested two tillage levels: no-till and conventional-tillage, two crop rotations: sweet-sorghum/winter grazing vetch/sweet sorghum and sweet-sorghum/winter fallow/sweet sorghum rotations and three crop residue retention levels: 30%, 15% and 0%. Tillage was the main factor to influence SOC and LOC fractions under the sweet sorghum cropping system in South Africa. NT increased SOC and all LOC fractions compared to CT, which concurs with previous findings. Cold water extractable organic carbon (CWEOC) and hot water extractable organic carbon (HWEOC) were found to be more sensitive to tillage and strongly positively correlated to SOC. An increase in residue retention led to an increase in microbial biomass carbon (MBC). This study concludes that CWEOC and HWEOC can serve as sensitive early indicators of change in soil quality and are an ideal proxy for SOC in the sweet-sorghum cropping system in South Africa.

The study was conducted to know the productivity and soil fertility status of intensified rice-wheat (RW) systems by adding a third pre-rice crop mungbeani.ewheat-mungbeanrice cropping pattern. The trial comprises five packages of practices including crop residue retention, seeding methods with tillage options imposed on the component crops in the same cropping pattern. The results indicated that keeping standing 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-mungbean-rice sequence compare to conventional practice of well-till without crop residue retention. System productivity and fertility were evaluated under five levels of tillage options (zero, strip, raised bed, minimum tillage by power tiller operated system (PTOS) and conventional tillage practice (CTP) in a RWM cropping pattern. Both permanent raised bed and strip till with 30% straw retention produced the highest productivity in all years and the lowest yield was also found from conventional practice with 30% straw retention.Soil organic matter in surface soil had increased by 0.12% after 3years crop cycles with 30% SR from rice and wheat and full residue retention from mungbean crop. Straw retention is an important component of soil management and may have long term positive impacts on soil quality. The combination of raised bedsystems and strip tillage with 30% residues retained appears to be a very promising technology for sustainable intensification of wheat-mungbean-rice croppingpattern in dry zone areas.

A study was conducted to compare wheat production under two previous paddy crop residue management systems by taking into account wheat growth parameters, yield attributes and economics of both systems. Farm testing of wheat production in two methods of management of paddy residue viz: sowing of wheat with happy seeder in previous paddy crop residue (paddy residue retention) and sowing of wheat with normal drill after burning of previous paddy residue (paddy residue burning: farmer practice) done in Ferozepur and Jalandhar districts on 10 farmers’ fields locations in each district during rabi season of 2016-17 and 2017-18. Dataset was analyzed using unpaired T test. Both paddy residue retention and paddy residue burning methods resulted in non-significant effect on growth parameters and yield attributes which resulted similar mean grain yields (5.48 t/ha) and (5.35 t/ha), respectively in both districts during two years of study. Paddy residue retention method reduced the cost of wheat cultivation and put a check on air pollution from burning of paddy residue in the field. It saved fertilizers by adding nutrients to the field.

A three yearsfield experiment was conducted at Regional Wheat Research Centre, Shyampur, Rajshahiduring 2014-15 to 2017-18 with an objective to observe the effects on soil fertility and performance of the crops under different tillage and residue management for rice-wheat (RW) systems by adding a third pre-rice crop of maize. The experiment was conducted in split plot design with three replication. The tillage options viz. (i) Strip tillage (ST) (ii) Permanent bed (PB) and (iii) conventional (CT) tillage; two crop residue management, viz. (i) 0%=no residue and (ii) 30% residue retention were studied. The results indicated that keeping 30% crop residue in the field with minimum disturbance of soil had significant contribution on grain yield of wheat-maize-rice sequence compare to conventional practice of well-till without crop residue retention.The permanent bed planting system gave the highest yields of wheat (4.37 tha-1), maize (7.31 tha-1) and rice (4.40 tha-1) and followed by strip tillage and lowest in conventional tillage. Among the residue management, 30% residue retention showed the highest yields of wheat (4.46tha- 1), maize (7.39 tha-1) and rice (4.69 tha-1). Considering economic performance of all tillage systems, the permanent bed planting system performed the best among all other tillage options and followed by strip tillage. Contrarily, 30% residue retention gave the highest yield and increased 0.12-0.14% organic matter into the soil with more productive.The results indicates that, both tillage systems coupled with 30% residue retention might be a good option for higher yield as well as soil fertility for Wheat-Maize- Taman rice cropping pattern in drought prone areas of Bangladesh.

Residue Retention

Very little is known about the changes that occur in soil organic carbon (SOC) and total nitrogen (TN) under an intensive rice-based cropping system following the change to minimal tillage and increased crop residue retention in the Gangetic Plains of South Asia. The field experiment was conducted for 3 years at Rajbari, Bangladesh to examine the impact of tillage practices and crop residue retention on carbon (C) and nitrogen (N) cycling. The experiment comprised four tillage practices—conventional tillage (CT), zero tillage (ZT), strip-tillage (ST), and bed planting (BP) in combination with two residue retention levels—increased residue (R50%) and low residue (R20%—the current practice). The TN, SOC, and mineral N (NH4+-N and NO3−-N) were measured in the soil at different crop growth stages. After 3 years, ZT, ST, and BP sequestered 12, 11, and 6% more SOC, and 18, 13, and 10% more TN, respectively than the conventional crop establishment practice at 0–5 cm soil depth. The accumulation of SOC and TN was also higher compared to the initial SOC and TN in soil. Among the tillage practices, the maximum SOC and TN sequestration were recorded with ST and with R50% that might be attributed to reduced mineralization of C and N in soil particularly with increased residue retention, since decay rates of potentially mineralizable C was lower in the ST with both the residue retention practices. Increased residue retention and minimum tillage practices after nine consecutive crops has altered the C and N cycling by slowing the in-season turnover of C and N, reducing the level of nitrate-N available to plants in the growing season and increasing retained soil levels of SOC and TN.
