PhenoCam images from ARSLTARMDCR site, Caroline County, Maryland, USA since 2017

    This data set consists of repeat digital imagery from a tower-mounted digital camera (hereafter, PhenoCam) maintained by the USDA-ARS Hydrology Remote Sensing Laboratory (HRSL) in the Lower Chesapeake Bay (LCB) watershed. HRSL is a member of the PhenoCam network, which has as its mission to serve as a long-term, continental-scale, phenological observatory. Imagery is uploaded to the PhenoCam server every 30 minutes.

      Sweet corn response to banded phosphorus in the Willamette Valley

        Six field experiments were conducted during 2012 and 2013 in the Willamette Valley, OR to evaluate corn ear yield and quality response to starter P fertilizer and whether current Oregon State University recommendations for starter P application are supported by recent data with contemporary corn varieties and production practices. While yield was not impacted by starter P fertilizer addition at any site-year, visual symptoms of P deficiency were observed at the site with the lowest soil test P value (42 mg kg-1). This research supports a 50 mg kg-1 P sufficiency threshold for modern sweet corn varieties.

        Data from: Interseeded cover crop mixtures influence soil water storage during the corn phase of corn-soybean-wheat no-till cropping systems

          This study was initiated to evaluate, during the following corn (*Zea mays* L.) phase, the effects of interseeded cover crops on soil temperature, soil water balances, evapotranspiration, infiltration, and yield and water use efficiency of corn. The study was conducted at the USDA Beltsville Agricultural Research Center, Beltsville, MD from 2017 through 2020. The cropping systems under study were primarily sequences of corn-soybean (*Glycine max* L.)-wheat (*Triticum aestivum* L.)-double crop soybean all planted with no-tillage management.

          Data from: Efficacy of deltamethrin and pirimiphos-methyl in layer-treated maize against the larger grain borer and the maize weevil

            Two grain surface treatment insecticides (deltamethrin and pirimiphos-methyl were evaluated in laboratory assays as a surface treatment for maize to control adult Prostephanus truncatus and Sitophilus zeamais. Both insecticides were applied to 20 g of maize placed in a vial or to the upper one half, one fourth, or one-eighth layer of the maize. Insects were either added to the vials before or after the maize. Mortality, progeny production, and insect damaged kernels (IDK) were then evaluated for each vial.

            FACETS enterprise crop budgets for NE Florida and SW Georgia

              Enterprise budgets contained in this database were developed as part of the Floridian Aquifer Collaborative Engagement for Sustainability (FACETS), a large-scale, multi-institutional, multi-disciplinary project funded by the United States Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA). The goal of this project is to promote the economic sustainability of agriculture and silviculture in North Florida and South Georgia while protecting water quantity, quality, and habitat in the Upper Floridan Aquifer and the springs and rivers it feeds. This dataset includes budgets developed for pine plantations, corn and peanut crops, and hay and pasture production in the Lower Suwannee River Basin, Florida.

              Southeast Purdue Agricultural Center (SEPAC) drainage research data, 1984-2020

                This dataset contains research data obtained during a long-term subsurface drainage research project conducted at the Southeast Purdue Agricultural Center in Jennings County, Indiana, from 1984 to 2020. The original goals of the project were to evaluate the effects of different subsurface drain spacings (drainage intensities) on drain flow and corn growth and yield. Additional objectives were added over the years, especially related to movement of agricultural chemicals (nitrate-N, other nutrients, and pesticides) through the soil into the drainage waters.
