Soil quality restoration and yield stabilization in acidic soils of northeastern Himalayas: Five years impact of green manuring and crop residue management

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Published: Sept. 6, 2022

Soil quality restoration and crop productivity maximization are the global challenge to feed galloping population. The task is much more daunting in a risk-prone, fragile, low productive hilly region due depletion of supporting regulating ecosystem services. A five-year long-term (2012–2017) field experiment was conducted stabilize yield soil through legume green manuring residue recycling intensified cropping systems Eastern Himalayan India. Four treatments involving three manures [green gram ( Vigna radiata ); cowpea unguiculata Sesbania aculeata ) along with control (no-green manure)], [groundnut Arachis hypogaea )—pea Pisum sativum maize Zea mays )—pea, + groundnut–pea] two levels management practices [residue removal retention] were evaluated times replicated split–split plot design. Among manure options, exerted significant positive impact on organic carbon (SOC) stock, available micro- (Fe, Mn, Zn, Cu), macronutrients (N, P K) surface (0–0.15 m) subsurface (0.15–0.45 soils. improvement enzymatic activities (acid phosphatase, alkaline dehydrogenase, beta-glucosidase, aryl sulfatase activity) p < 0.05) -treated +28.1% +38.9% +18.3% +27.3% soils over non-green manure. also exhibited higher index (SQI) stratification ratio (SR) nutrients enzymes manured systems, groundnut intercropped followed by peas (MGP) situ retention increased macro- micronutrients, SOC enzymes, SR, SQI comparison other systems. improved sustainability +19% +11% MGP system removal, respectively. Therefore, recommended for stabilizing enhancing services maintaining fragile

Effects of Biodegradable Film and Polyethylene Film Residues on Soil Moisture and Maize Productivity in Dryland

Agriculture, Journal Year: 2023, Volume and Issue: 13(2), P. 332 - 332

Published: Jan. 29, 2023

With the dramatic increased use of agricultural film, potential environmental risks associated with it have been receiving widespread attention. Biodegradable film (BF) is considered an alternative to conventional polyethylene (PF), but its feasibility replace PF needs be verified. Thus, we conducted a two-year field experiment in Loess Plateau region China, exploring effects residual biodegradable and (RBF RPF) on soil moisture, maize root, productivity at different levels (75 kg ha−1, 150 ha−1 300 ha−1). Regardless type, water content (SWC), root length density (RLD), surface area (RSD) all decreased increasing level; this phenomenon observed significant differences when level exceeded ha−1. Different organs (root shoot) differed their sensitivity period film. The degradation rate RBF was 59.24%, which higher than that RPF. Compared RPF treatments, SWC, RLD, RSD, biomass, root–shoot ratio treatments were closer no treatment second growing season. After experiment, compared grain yield, efficiency, precipitation efficiency 0.41–6.24%, 0.12–4.44%, 0.41–06.24%. application BF beneficial sustainable production dryland, finding efficient methods recycle remains priority.

Increased uptake of deep soil water promotes drought resistance in mixed forests

Plant Cell & Environment, Journal Year: 2023, Volume and Issue: 46(11), P. 3218 - 3228

Published: June 7, 2023

The intensity and frequency of droughts are projected to rise in recent years adversely affect forests. Thus, information on plant water use acclimation during after is crucial. This study used the stable isotope thermal dissipation probes detect water-use adaptation mixed forests drought using a precipitation gradient control experiment field. results showed that Platycladus orientalis Quercus variabilis mainly absorbed from deep soil layers (32.05% 28.2%, respectively). synergetic nocturnal sap flow both species replenished loss, but P. experienced greater decline transpiration drought. Q. remained high since it was induced by radiation. After short-term exposure drought, majorly obtained shallow water, confirming its sensitivity water. Contrarily, regardless content. Therefore, these findings suggest cannot physiologically adjust extreme events, possibly limiting their future distributions altering composition boreal
