“…The litter layer, formed by litterfall and consumed by comminutors and decomposers, constitutes the main resource of energy and matter for a diverse community of soil organisms connected by highly complex interactions (Bargali et al 2015;Hättenschwiler et al 2005). The interaction between litter and decomposers plays an important role in regulating nutrient and carbon cycling, maintaining soil fertility in forests and in agricultural systems (Karki et al 2021a, b;Manral et al 2020;Padalia et al 2021;Yang et al 2004). Standing litter protects the soil surface from runoff and erosion (Liu et al 2017).…”

Backgrounds and aims Litter protects the underlying soil, depending on litterfall and decomposition, but dynamics of the standing litter stock in agroforestry systems remain poorly understood. We aimed to unravel effects of litter quality, temporal patterns, microclimate, and a possible home-field advantage (HFA) on standing litter dynamics across a land-use gradient. Methods We quantified litterfall, the standing litter stock, and microclimate during a year in (remnant) forest, cacao-based simple and complex agroforestry, cacao monocultures, and annual crops in a cacao producing area in Indonesia. We conducted a reciprocal litter transfer experiment, and tested decomposition rates of pruning residues. Standing litter stocks during the year were estimated from monthly litterfall and decomposition rates. Results Variation in litter quality influenced decomposition rates more strongly than variation in microclimate or HFA. Lower litter quality in complex agroforestry and in the cacao monoculture decreased the decay rate compared to simple agroforestry systems; mean litter residence time was over a year. Mixing high- and low-quality material in pruning residues modified the decomposition rate, soil C and N changes, offering options for targeted management of soil protection and nutrient release. Conclusions The seasonal patterns of litterfall and relatively slow decomposition rates supported permanence of the litter layer in all cacao production systems, protecting the underlying soil.

“…Population load, poverty, agricultural expansion and intensification, and development of infrastructure have been suggested as major threats to soil structure and biodiversity [ 1 , 2 , 3 ]. Due to the above-mentioned disturbances, land-use systems have been affected adversely in terms of microbial activities, nutrient cycling, and reduced the soil productivity [ 4 , 5 , 6 ]. To cope with this situation, options are often used to make the soil more productive and sustainable.…”

The application of organic manures was found to be beneficial, however, the integrated use of organic manures with chemical nitrogen fertilizers has proven more sustainable in increasing the photosynthetic attributes and grain yield of the winter-wheat crop. A multi-factor split-plot design was adopted, nitrogen and manure fertilizer treatments were set in the sub-plots, including nitrogen-gradient treatment of T1:0 kg N ha−1, T2:100 kg N ha−1, T3:200 kg N ha−1, and T4:300 kg N ha−1 (pure nitrogen -fertilizer application) The 25% reduction in nitrogen combined with the manure-fertilizer application includes T5:75 kg N ha−1 nitrogen and 25 kg N ha−1 manure, T6:150 kg N ha−1 nitrogen and 50 kg N ha−1 manure, and T7:225 kg N ha−1 nitrogen and 75 kg N ha−1 manure. The maximum results of the total chlorophyll content and photosynthetic rate were 5.73 mg/g FW and 68.13 m mol m−2 s−1, observed under T4 in Zhongmai 175, as compared to Jindong 22 at the heading stage. However, the maximum results of intercellular CO2 concentration were 1998.47 μmol mol−1, observed under T3 in Jindong 22, as compared to Zhongmai 175 at the tillering stage. The maximum results of LAI were 5.35 (cm2), observed under T7 in Jindong 22, as compared to Zhongmai 175 at the booting stage. However, the maximum results of Tr and Gs were 6.31 mmol H2O m−2 s−1 and 0.90 H2O mol m−2 s−1, respectively, observed under T7 in Zhongmai 175 as compared to Jindong 22 at the flowering stage. The results revealed that grain yield 8696.93 kg ha−1, grains spike−1 51.33 (g), and 1000-grain weight 39.27 (g) were significantly higher, under T3 in Zhongmai 175, as compared to Jindong 22. Moreover, the spike number plot−1 of 656.67 m2 was significantly higher in Jindong 22, as compared to Zhongmai 175. It was concluded from the study that the combined application of nitrogen and manure fertilizers in winter wheat is significant for enhancing seed at the jointing and flowering stages. For increased grain yield and higher economic return, Zhongmai 175 outperformed the other cultivars examined. This research brings awareness toward the nitrogen-fertilizer-management approach established for farmers’ practice, which might be observed as an instruction to increase agricultural management for the winter-wheat-growth season.

In addition, this system enhances the biodiversity, preserve the environmental and ecological benefits, nutritional security, soil conservation potential, mitigation of carbon dioxide emissions and job opportunity (V. Kumar & Tiwari, 2017;Padalia et al, 2022;Vibhuti et al, 2020). Ecological and socioeconomic factors including geographic area, weather, water accessibility, homegarden size, agricultural policy, market needs and household aspects are determining factors influencing the diversity and utilization of products obtained from the traditional homegardens (K.

The aim of the present study was to analyse the species utilization pattern and their relative prevalence in homegardens varying in size and altitude. Four sites were selected along an altitudinal gradient viz., very low (up to 350 m), low (350-700 m), mid (700-1500 m) and high altitudes (above 2000 m) in Kumaun Himalaya, India. At each altitude, homegardens were categorized into three size classes viz., large (above 0.007 ha), medium (0.004-0.006 ha) and small homegardens (up to 0.003 ha). Maximum species richness was recorded in large sized homegarden at all altitudes except mid altitude where maximum species was observed in medium sized homegardens. Across altitudes, maximum plant species (39) was recorded at mid altitude whereas minimum species (24) were present in high altitude homegardens. Amaryllidaceae was the most important family followed by Oxalidaceae across all the altitudes. In case of plant utilization pattern, maximum species were utilized as a medicine (44.23 %) followed by vegetables (26.66 %), fodder (18.1 %), miscellaneous (15.97 %), spices (13.97 %) and fruits (12.34 %). Among the species, A. cepa (1380) and C. annuum (1026) showed most prevalence whereas S. cumini (278) was the least prevalent species. Across the altitudinal gradient, mid altitude showed most (2341, 1330) relative prevalence whereas high altitude showed least (876, 0) relative prevalence for A. cepa and M. indica, respectively. Management practices and conventional activity could show a higher effect on species composition and their utilization pattern to improve food security and conserving plant genetic diversity in altitudes.
