“…Islam et al (2016) also found that residue retention turned negative N balances into positive balances under a lentil-mung bean-monsoon rice rotation. By contrast, Boateng and Dennis (2000) showed that application of residue had no significant effect on N uptake by crops, while surface application of residue reduced N uptake and crop yield by N immobilisation (Soon and Lupwayi, 2012). It is likely that after 12-14 successive crops, as in the present study, the N immobilisation processes are suppressed due to the larger stock of soil organic carbon (Alam et al, 2018) and soil N (present study).…”

On-farm adoption of minimum soil disturbance and increased residue retention will alter nitrogen (N) dynamics in soils and N fertiliser management in the intensive rice-based triple cropping systems of the Eastern Gangetic Plains. However, the consequences of changes in N forms, N mineralisation and its availability for crops have not been determined. Field experiments were conducted at two locations (Alipur and Digram) of north-west Bangladesh (NWB) to examine N cycling under three planting practices (conventional tillage (CT), strip planting (SP) and bed planting (BP)) with increased (HR) or low residue retention (LR-the current practice) on Calcareous Brown Flood Plain and Grey Terrace soils. Total N and available N were measured on soil samples as was N uptake by crops at different growth stages in the 13-14th (Alipur) and 12-13th (Digram) crops since treatments commenced. At each location (0-10 cm soil depth), SP, including non-puddled transplanting of rice seedlings (NP), together with HR increased total N by 9 and 32 % relative to BPHR, and CTHR and by 62 % relative to the current farm practice (CTLR). In general, the cumulative available N in soils during mustard and rice cropping under CT with HR was higher than other crop establishment and residue retention practices while under wheat and jute, total availability of N did not vary among crop establishment types with increased residue retention. Nitrogen availability in the initial phase of crop growth (0-60 DAS) was generally higher with CT than SP and BP. By contrast, for all crops, the estimated potentially mineralisable N was higher and its decay rate was lower under SPHR than other crop establishment and residue retention practices. Conservation Agriculture practices (SP, and NP of rice, together with HR) have altered the N cycling by reducing the level of mineral N available to plants in the early growing season when crop demand is low, but by increasing soil total N (0−10 cm) and plant N uptake which enhanced the synchrony between crop demand and available N supply. establishment practice designed for CA cropping systems (Alam et al., 2016a;Haque et al., 2016), along with zero tillage or strip planting are CA-compatible practices for rice. However, there is limited understanding of cycling of N in soils under the CA practices in intensive rice-based triple cropping systems which involve the rotation of winter dryland and summer wetland rice crops.An improved knowledge about the dynamics of residue nitrogen (N) turnover and the availability of both soil native N and fertiliser N is required to quantify the effects of minimum soil disturbance and increased crop residue retention on soil quality, crop production and N fertilizer management. As native soil N mineralisation provides 20-80

“…When crop residues were exported, the soil was exposed to erosion (mainly wind erosion), and inputs of organic matter to the soil decreased, which explains the low SOM (less than 1.5%) and P contents, as reported elsewhere in the literature [58,61]. In addition, bare soil increases water evaporation from the soil [61,62], and erosion decreases the rooting zone depth and water-holding capacity, which decreases soil productivity by removing organic matter, nutrients, and fine particles with the topsoil [63,64]. These impacts tend to be more extreme in oases because of the arid climate, soil texture, and degraded soil structure, since these factors make the soil highly erodible [11,64].…”

Thus, low SOM content in this region was caused mainly by inadequate management of crop residues and applying too little manure or compost.…”

Circular agriculture is an effective approach for the management of soil organic inputs that improves soil fertility and cropping system sustainability. We developed a cropping system typology and assessed effects of crop rotation, organic fertilization, and crop residue management on soil fertility properties. Farmers in Drâa-Tafilalet oases in Morocco were surveyed, and soil was sampled and analyzed. In the most common cropping systems (Type I), date palms were associated with cereals, forages, and perennial crops. Type II cropping systems referred to a monocropped date palm of only one cultivar. In Type III, date palm was associated with other crops on part of the utilized agricultural area and monocropped on the other part. In all cropping systems, mean soil organic matter (SOM) content was less than 1.5% and the SOM:clay ratio was less than 12%, which increased the soil degradation risk. Livestock was combined with crops in Type I and III cropping systems and produced 19.4 and 24.2 t of manure per farm per year, respectively. Type I and II cropping systems produced annually 0.98 and 2.1 t.ha−1 of dry palms, respectively. Recycling these organic waste products remains a promising option that could produce organic inputs and offset the current lack of manure.

“…The probable reasons for the increased N uptake could be associated with the increased availability of directly added N. The decreased soil surface temperature [ 41 , 42 ] and lower water losses in mulched plots have been reported to increase the grain yield and nutrient uptake in soybean crops [ 43 ]. Similarly, the increased decomposition of crop residues led to an increase in the release of nitrogen, which corresponded with plant N uptake, irrespective of the fertilizer source of N, and resulted in decreased N losses and, hence, increased the N uptake and crop yield [ 44 , 45 ]. These arguments support the trend of our data, indicating positive and linear relationships of N uptake with the grain and the biological yields of maize.…”

Mulching and nitrogen (N) fertilization are the main drivers for sustainable crop production. The sole use of nitrogen fertilizer threatened both the physiology and production of maize in rain-fed areas. Therefore, we proposed that wheat straw mulching with N fertilization would increase maize yield by improving soil fertility, physiology, and nitrogen use efficiency. A two-year field study evaluated the effects of CK (control), N (nitrogen application at 172 kg ha−1), HS (half wheat straw mulch, 2500 kg ha−1), HS+N (half wheat straw, 2500 kg ha−1 plus 172 kg N ha−1), FS (full wheat straw, 5000 kg ha−1), and FS+N (full wheat straw, 5000 kg ha−1 plus 172 kg N ha−1) on maize growth, physiology, and biochemistry. Compared with the control, the FS+N treatment resulted in the increase of 56% photosynthetic efficiency, 9.6% nitrogen use efficiency, 60% nitrogen uptake, 80% soluble sugar, 59% starches, 48% biomass, and 29% grain yield of maize. In addition, the FS+N regime increased 47%, 42%, and 106% of soil organic carbon and available P and N content in comparison with the control. Maize grain and biomass yields were positively correlated with N uptake, photosynthesis, soil organic carbon, and soil available N and P contents. Conclusively, the use of wheat straw at 5000 kg ha−1, along with 172 kg N ha−1, is a promising option for building a sustainable wheat–maize cropping system to achieve optimal crop yield and improved plant and soil health in a semi-arid region of China.
