Runoff maintenance and sediment reduction of different

May 01, 2019· Plant growth could improve soil conditions through fine root-network development and litter accumulation, which forms a virtuous cycle to control soil loss Gyssels et al., 2005, Xu et al., 2009, Wu et al., 2016. Thus, grasslands with accumulated fibrous roots in shallow soil had better effects on reducing sediment yield.

Plant root exudation under drought: implications

Sep 30, 2019· Root exudates are a pathway for plant–microbial communication and play a key role in ecosystem response to environmental change. Here, we collate recent evidence that shows that plants of different growth strategies differ in their root exudation, that root exudates can select for beneficial soil microbial communities, and that drought affects the quantity and quality of root exudation.

Is the way cattle are grazed the key to saving America's

Grassland of the world

Nov 20, 2004· This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have

Establishment gaps in species‐poor grasslands: artificial

Implications for Practice. Establishment gaps are widely applicable tools to increase the diversity of species‐poor grasslands. Gaps of 4 m 2 represent a more feasible solution compared to larger openings also for the farmers, because there is only a moderate level of weed encroachment and smaller soil disturbance occurs during their creation.; We recommend sowing high‐diversity seed...

Role of Seed Bank in Establishment of Single and Mixed

Artificial grassland establishment is one of the fastest and most effective ways to restore the productivity of degraded grasslands. Little is known about the effect of different types of artificial grassland establishment i.e., single- and mixed-sowing grassland establishment with perennial grasses on soil seed bank in degraded grassland ecosystems.

Natural grasslands maintain soil water sustainability

Dec 01, 2019· Therefore, grasslands should be the dominant vegetation type for vegetation restoration in water-limited areas Yu et al., 2015. Compared with natural grassland, planted grassland is one of the more quickly and effective way to improve land productivity and ecological environment.

Ecological restoration alters microbial communities in

Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings.

The contributions of soil mesofauna to leaf and root

2.2. Litter decomposition experiment. On February 1, 2018, we collected freshly senesced L. perenne and T. repens leaf litter and root from soil-vegetation monoliths in the top 25 cm soil profile. It was not possible to determine the timing of death of fine roots in soil accurately, thus a mixture of both live and dead roots was collected Smith et al., 2014.

The asymptotic response of soil water holding capacity

Apr 17, 2018· The artificial grassland is one of the most important practices to restore degraded alpine meadow. However, it is still not clear how the water conservation capacity respond along the restoration duration. We conducted the experiment for soil water holding capacity along the restoration duration of 0 year extremely degradation, CK, 2 years 2Y, 4 years 4Y, 6 years 6Y and 12 years (12Y...

Quantifying the effect of ecological restoration on runoff

Nov 05, 2017· The results showed that artificial grassland, forest, natural grassland, and shrubland had higher runoff and sediment reduction effectiveness. The annual runoff reduction effectiveness of the ecological restoration overall was 72.18% with the effects of artificial grassland, natural grassland, shrubland, and forest at 71.89%, 50.60%, 73.18%...

Positive diversity–invasibility relationship in species

Methods. In species-rich grassland, one seed of each of ten species was added to each of 50 contiguous 16 cm 2 quadrats within seven plots 8 × 100 cm. The emergence of these species was recorded in seven control plots, and establishment success was measured in relation to the species diversity of the resident vegetation at two spatial scales, quadrat 64 cm 2 within plots 800 cm 2
