Thinning is common and effective practice for managing forests worldwide, impacting soil nitrogen (N). Nonetheless, uncertainties remain because thinning experiments have recorded either increased, decreased, or unchanged soil N storage. This study investigated soil N storage across 13 temperate forests, each of which received three thinning intensities (unthinned control and 15–50% basal area removal) under varying pre-treatment conditions (altitude, slope, soil pH, soil moisture, stand age, stand density, diameter at breast height, and tree height). The total N stored in the forest floor and mineral soils (0–10, 10–20, and 20–30 cm) was determined 1, 4, and 7 years after thinning. Given the various site conditions and thinning regimes, a standardized effect size was used to analyze the influences of thinning. The N storage (Mg N ha-1) of the forest floor and at 0–10, 10–20, and 20–30 cm mineral soil depths was 0.02–0.46, 0.32–3.21, 0.29–3.03, and 0.25–2.54 across the 13 forests, respectively. The standardized effect sizes indicated a general decrease in forest floor N storage and increase in mineral soil N storage under thinning. However, the effect sizes varied because of differing site conditions, even more than thinning intensity and recovery time. Soil pH and stand age were the most influential factors for the effect sizes of forest floor and mineral soil N storage, respectively (P © 2023, The Authors. All rights reserved.

He received his B.S. M.E. and Ph.D. from Virginia Polytechnic Institute and State University. Currently his research and extension programs address water quality impacts of agricultural best management practices.3 Leslie L. Shoemaker is a former USDA National Needs Fellow in the Department of Agricultural Engineering where she is pursuing a Ph.D. degree (Agricultural Engineering Department University of Maryland College Park MD 20742-5711). The focus of her research program is on augmentation of the GLEAMS model to describe the hydrologic behavior of the vadose zone. She previously has been extensively involved in model applications for non-point source pollution control both in a graduate degree program at Cornell University and as an engineer with the Interstate Commission on the Potomac River Basin. She is currently employed as a water resources engineer with Green-home and O'Mara Greenbelt Maryland.

Non-point source pollution of ground water systems has become a national concern in recent years. Researchers and regulatory agencies are investigating the source and processes of the contamination. Agricultural best management practices (BMPs) traditionally developed to reduce non-point source pollution of surface water resources are being investigated for their impact on ground water quality. This study used the CREAMS model to simulate the long-term effects of seven different BMPs on nitrate nitrogen (NO3-N) loadings to a shallow, unconfined ground water system. Two representative watersheds, 5.8 and 8.9 hectares (14.3 and 22 acres) in area, in the Coastal Plain physiographic region of Maryland were selected for study. Soils in these watersheds belong to the Matapeake silt loam series and have moderate infiltration capacity. Results from this study indicated that BMP's used in conjunction with winter cover (barley) reduced NO3-N leaching to the ground water system. It was also found that turfgrass reduced surface losses of water and nitrogen, but increased leaching losses of water and NO3-N significantly. All of the BMPs simulated in this study resulted in leachate NO3-N concentrations exceeding 10 ppm, the U.S. EPA health standard for public drinking water, indicating a need for alternate practices for reducing nitrate leaching.

Excellence, potential, and good prospects make palm oil plantations grow rapidly. Another underlying consideration is the important and strategic role as a activator nor accelerator in development and economy. Environmental and social issues become challenging in development's sector, especially in the development of sustainable oil palm plantations. Since the implementations of the certification system for sustainable palm oil plantation's in 2011 and was further clarified in Regulation of the Minister of Agriculture No. 11 of 2015 about Indonesian Sustainable Palm Oil Certification System (ISPO), the Indonesian Government requires companies to produce palm oil sustainably. This research aims to analysis on the performance of oil palm plantations in environmental management based on ISPO principles and criteria. Research on several palm oil plantations of South Sumetera Province located in Musi Banyuasin Regency. Methods were used by collecting primary data through interviews and secondary data was obtained from data reviews such as company literature. The results of the analysis showed that the effectiveness of policy implementation through the fulfillment of environmental policy components can be fulfilled by most of companies. Meanwhile, in some cases, such as online reporting of land fires has not been fulfilled yet.

Temporal NDVI analysis to detect the effects of seawater intrusion on rice growth in coastal areas

引用

IOP Conference Series: Earth and Environmental Science 2021年第1期662卷

作者： T A Tivianton B Barus M Y J Purwanto S Anwar Widiatmaka R Laudiansyah Natural Resources and Environmental Management Study Program the IPB Graduate School Bogor Indonesia Department of Environmental Geography Faculty of Geography Universitas Gadjah Mada Yogyakarta Indonesia

As population size grows over time, staple food production also needs to keep up with increased annual demands. In Indonesia, the agricultural sector applies intensification and extensification to maximize rice productivity. However, farm extensification can instead decline productivity, should it sprawl into marginal lands like the study area that has been affected by sea-level rise impact, i.e., surface saltwater intrusion. Therefore, this study set out to differentiate paddies into segments affected and unaffected by salinity based on discernible variation in rice growth stages. These stages were determined using a vegetation index, NDVI (Normalized Difference Vegetation Index), calculated from time-series Sentinel-2 L2A+B image data from 2015 until 2020. The resulting temporal NDVI showed two cropping patterns year-round but with different planting times. In salinity-unaffected paddy segments, farmers began the inundation-transplanting stage in late March and ended the cropping season with fallow in August. Meanwhile, in salinity-affected segments, the cropping stages were the opposite: inundation in early April and fallow in early September. The measurable impact of salinity was apparent at the vegetative-generative stage, where salinity-affected paddies had the highest NDVI of 0.64–0.65, whereas those unaffected had the highest NDVI of 0.7–0.75. These index values indicate an impaired rice growth rate due to salinity effects. Compared with the field-measured data, the NDVI showed 85% accuracy, with a Kappa coefficient of 0.87. Meanwhile, the NDVI-EC correlation test produced R-values of 63–85%. Overall, this research has confirmed that remote sensing image and technology can acquire variable data that explain salinity effects on coastal paddies.

Organic matter that resides in the sandy, acidic soils of the northern forest is thought to be stabilized in organo-mineral particles ( 20 µm in size). Here we use a forested landscape near Sudbury, Ontario, Canada where logging and metal-mining pollution had caused soil erosion prior to being restored and reforested. We use a combination of physical fractionation (size) and chemical fractionation (carbon to nitrogen ratio, natural abundance of stable isotopes of carbon and nitrogen). The composition of bulk soils with young trees (13-yr old) was 25% microaggregates (53 to 250 µm in size) and 47% in a smaller silt + clay fraction (250 µm in size), microaggregates, and silt + clay fraction. The C density was much greater and less decomposed for macroaggregates than for the silt + clay fraction. Untreated sites, with trees but not restored with added lime, had a smaller proportion of macroaggregates in bulk soil. Even though aggregate structures typically are not associated with sandy, acidic forest soils, the results for these Regosols in the northern forest of the Greater Sudbury region show that stabilized soil C involves formation of macroaggregates along with microaggregates, both of which help to stabilize particulate organic matter. © 2023, The Authors.
