Crop Conversion from Annual to Perennials: An Effective Strategy to Increase Soil Multifunctionality

Опубликована: Янв. 16, 2024

Although crop conversion from annual to perennial crops has been considered as one path towards climate-smart and resource-efficient agriculture, the effects of this on soil multifunctionality biomass yields remain unclear. Here, we investigated three (a grass (Lolium perenne), a legume (Medicago sativa), their mixture) yield Yellow River floodplain. Soil was assessed by capacity water regulation carbon (C), nitrogen (N), phosphorus (P) cycles. Results showed that enhanced 207% for L. perenne, 311% M. sativa, 438% perenne + compared with winter wheat (Triticum aestivum). The effect increased infiltration rate, dissolved organic C, microbial extracellular enzymatic activities both C N acquisition. However, observed had lower than crop. Therefore, transition agricultural landscapes perennials needs take into account balance between environmental protection food security, well heterogeneity, promote sustainable development.

Effects of Variation in Tamarix chinensis Plantations on Soil Microbial Community Composition in the Middle Yellow River Floodplain

International Journal of Environmental Research and Public Health, Год журнала: 2023, Номер 20(6), С. 5015 - 5015

Floodplains have important ecological and hydrological functions in terrestrial ecosystems, experience severe soil erosion, are vulnerable to losing fertility. Tamarix chinensis Lour. plantation is the main vegetation restoration measure for maintaining quality floodplains. Soil microorganisms essential driving biogeochemical cycling processes. However, effects of sampling location shrub patch size on microbial community composition remain unclear. In this study, we characterized changes structure, as well factors them, inside- outside-canopy soils three sizes (small, medium, large) T. plants middle Yellow River floodplain. Compared with soils, inside-canopy had higher phospholipid fatty acids (PLFAs), including fungi, bacteria, Gram-positive bacteria (GP), Gram-negative (GN), arbuscular mycorrhizal fungi. The ratio fungi GP GN gradually decreased increased. Differences between nutrients (organic matter, total nitrogen, available phosphorus) salt content increased by 59.73%, 40.75%, 34.41%, 110.08% from small large size. Changes were mainly driven variation organic which accounted 61.90% soils. Resource islands could alter effect was stronger when large. results indicated that plantations enhanced nutrient contents elevated biomass changed composition; might thus provide a suitable approach restoring degraded floodplain ecosystems.

Although crop conversion from annual to perennial crops has been considered as one path towards climate-smart and resource-efficient agriculture, the effects of this on soil multifunctionality biomass yields remain unclear. The objective study is enhance while exerting a marginal influence farmer income. Here, we investigated winter wheat (Triticum aestivum L.) two (a grass (Lolium perenne L.), legume (Medicago sativa their mixture) yield Yellow River floodplain. Soil was assessed by capacity water regulation carbon (C), nitrogen (N), phosphorus (P) cycles. C cycle index average β-xylosidase, β-cellobiosidase, β-1, 4-glucosidase.

Love your wet grass! Dry season grazing reserves show highest grass regrowth in communal semi-arid rangelands of Tanzania

PLoS ONE, Год журнала: 2024, Номер 19(11), С. e0313818 - e0313818

Land management by seasonal migratory herding, traditionally implemented pastoralists, has allowed semi-arid rangeland ecosystems to remain productive and resilient highly erratic, rainfall patterns. Changing pastoralist practices patterns due climate change have the potential negatively influence resilience of rangelands. To test impact different communal increasing frequency disturbance on rangelands’ vegetation, we established a clipping experiment in three types: rainy season rangeland, dry exclosures, Maasai Steppe, northern Tanzania. Across these types, tested two frequencies monthly vs. once per growing period either fenced or open grazing (herbivory) over consecutive periods. We found that exhibited lowest regrowth rates highest proportion bare ground across herbivory, period. When was low, exclosures showed herbivory plots were seasonally clipped excluded herbivores generated significantly more grass biomass, higher compared all other treatments. Excluding had little vegetation biomass cover but positive when high. Seasonal for lower ground, most cases clipping. conclude traditional herding is relevant concept sustain productivity under intensity if pressure rangelands adapted conditions sufficient resting time after heavy defoliation granted. Dry (including resting) proved be sustainable maintain control erosion.

This study aimed to clarify the effects of stumping on preferential flow in understory soils Hippophae rhamnoides and assess appropriate height for optimization flow. Root properties, soil different H. stump heights (0, 10, 15, 20 cm, no-stumping, labeled conditions S1, S2, S3, S4, CK, respectively) were studied using situ dye-tracing laboratory analysis. The results showed that significantly increased development. effect was maximized condition with coverage (DC) 36.77%, maximum dye depth (MaxD) 40.02 uniform infiltration (Unifr) 14.28 ratio (PF fr ) 23.85%, length index (LI) 96.72%.

Rainwater harvesting (RH) techniques, specifically the implementation of Bio-pore Infiltration Holes (BIH), have been investigated as cost-effective and practical methods for managing surface runoff mitigating flood risks. This study aimed to evaluate infiltration rates BIH in secondary forest agricultural moorland areas, providing a basis sustainable soil water conservation practices. A survey methodology was employed assess using Horton equation model applied circular holes with depth 50 cm. Soil samples were collected from vicinity analysis physical properties at Science Laboratory, Faculty Agriculture, Tadulako University. 4-inch diameter PVC pipe, inserted 30 cm into soil, used measure infiltration, levels recorded up 60 The findings indicated that both lands moderate. characteristics including its texture organic carbon content, identified suboptimal, which constrained efficiency waste absorption through process. land types classified sandy according USDA standards, making it susceptible erosion, is directly related capacity potential transport during erosion events. content relatively low, 2.50% 1.17% land, indicating medium-level criteria content.
