Abstract Human‐induced landscape changes affect hydrologic responses (e.g., floods) that can be detected from a suite of satellite and model data sets. Tapping these vast sets using machine learning algorithms produce critically important accurate insights. In the Red River North Basin in United States, agricultural subsurface drainage (SD; so‐called tile drainage) systems have greatly increased since late 1990s. Over this period, river flow has markedly 6 13 major floods during past century...

A web-based decision support tool, zone mapping application for precision farming (ZoneMAP, http://zonemap.umac.org ), has been developed to automatically determine the optimal number of management zones and delineate them using satellite imagery field data provided by users. Application rates, such as fertilizer, can be prescribed each downloaded in a variety formats ensure compatibility with GPS-enabled equipment. ZoneMAP is linked Digital Northern Great Plains, which hosts an archive...

Many laboratories appraise soil salinity measurement electrical conductivity to water (EC1:5) due its simplicity. However, influence on plant growth is mainly based (ECe), so it necessary convert EC1:5 ECe in order assess response. The objectives this research were develop models relating under four different equilibration methods:...

Core Ideas Soil water release curve is important but difficult to measure. HYPROP and WP4 are used develop the soil curves for three soils. provided a good simple way measure curves. A (SWRC) describes critical soil‐specific relationship between content matric potential. In this study, moisture corresponding potentials were measured using (1) new method by dewpoint potentiometer, and, (2) traditional hanging column, Tempe cell, pressure plate. The SWRCs developed Fargo silty clay, Glyndon...

Water table contribution to plant water use is a significant element in improving efficiency (WUE) for agricultural management. In this study, lysimeter experiments were conducted controlled greenhouse environment investigate the response of soybean uptake and growth parameters under four different depths (WTD) (30, 50, 70, 90 cm). Soybean crop use, WUE, root distribution WTD examined. For 30, cm treatments, average contributions 89, 83, 79, 72%; grain yields 15.1, 10.5, 14.1, 17.2 g/lys.;...

Highlights Drainage water recycling captures and stores agricultural drainage for reuse as supplemental irrigation. can both increase crop production benefit downstream quality. Depending on management, also provide other complementary benefits. Research needs to advance are presented discussed. Keywords: quality, reuse, Subsurface drainage, Supplemental irrigation, Agricultural resiliency.

Abstract We downloaded the mRNA expression profiles of patients with LUAD and corresponding clinical data from The Cancer Genome Atlas (TCGA) database used Least Absolute Shrinkage Selection Operator Cox regression model to construct a multigene signature in TCGA cohort, which was validated patient GEO cohort. Results showed differences levels 120 necroptosis-related genes between normal tumor tissues. An eight-gene (CYLD, FADD, H2AX, RBCK1, PPIA, PPID, VDAC1, VDAC2) constructed through...

Agricultural subsurface drainage changes the field hydrology and potentially amount of water available to crop by altering flow path rate timing removal. Evapotranspiration (ET) is normally among largest components budget, in ET from introduction are likely have a greater influence on overall yield (surface runoff plus drainage) drained (TD) fields compared without (UD). To test this hypothesis, we examined impact at two sites located Upper Midwest (North Dakota-Site 1 South 2) using Landsat...

Abstract Drainage water recycling (DWR) involves capture, storage, and reuse of surface subsurface drainage as irrigation to enhance crop production during critical times the growing season. Our objectives were synthesize 53 site‐years data from 1996 2017 in midwestern United States determine effect DWR using primarily subirrigation on corn ( Zea mays L.) grain yield variability identify precipitation factors at key stages development (V1–V8, V9–VT, R1–R2, R3–R4, R5–R6) that correlated an...

Three weighing lysimeters were developed for evapotranspiration research at the University of Florida, Instituteof Food and Agricultural Sciences, Plant Science Research Education Unit near Citra, Florida. The lysimeter designfollowed accepted procedures as well aspects unique to study site, including a foundation designed perched watertable outside lysimeters, fetch distance, deep drainage, lightning protection. Each has planted surfacearea 2.32 m2 soil depth 1.37 m. in each is...

A field experiment was conducted during the 2009 and 2010 growing seasons to determine effect of subsurface drainage (SSD) on evapotranspiration (ET) crop coefficients (Kc) for a farm in Red River Valley North Dakota. The total area 44 ha, half which had installed fall 2002 at an approximate depth 1.1 m spacing 18.3 m. Corn (Zea mays) planted soybean (Glycine max) 2010. Evapotranspiration rates were measured both SSD surface drained [or undrained (UD)] by using eddy covariance (EC) method....

Abstract A study was conducted at three sites in North Dakota to strengthen understanding of the usefulness different proximal geophysical data types agricultural contexts varying pedology. This hypothesizes that electromagnetic induction (EMI), gamma‐ray sensor (GRS), cosmic‐ray neutron (CRNS), and elevation layers are all useful multiple linear regression (MLR) predictions soil properties meet expert criteria sites. In addition collection with vehicle‐mounted sensors, 15 samples were...

Lysimeter experiments were conducted under greenhouse conditions to investigate canola (Brassica napus L.) plant water use, growth, and yield parameters for three different table depths of 30, 60, 90 cm. Additionally, control conducted, only irrigation was applied these lysimeters without limitations. The plant’s tolerance level shallow groundwater determined. Results showed that contributions the treatments at cm 97%, 71%, 68%, respectively, while average grain yields 4.5, 5.3, 6.3 gr,...

Abstract This paper describes a multi-site and multi-decadal dataset of artificially drained agricultural fields in seven Midwest states North Carolina, USA. Thirty-nine research sites provided data on three conservation practices for cropland with subsurface tile drainage: saturated buffers, controlled drainage, drainage water recycling. These utilize vegetation and/or infrastructure to minimize off-site nutrient losses retain the landscape. A total 219 variables are reported, including 90...

Florida citrus groves are typically grown in two regions of the state: flatwoods and ridge. The southern area has poorly drained fine textured sands with low organic matter shallow root zone. Ridge is located northern ridge zone to coarse water-holding capacity. Two commercial groves, selected from each region, were studied 15 July 2004 14 2005. (FC) grove had a grass cover used drainage ditches remove excess water (RC) bare soil surface weeds periodically eliminated by tillage. Citrus crop...
