Understanding The Perceptions Of Producers Regarding The Ogallala Aquifer Use: A Survey Report (2022), Jonathan Aguilar, Amariah Fischer, Matthew R. Sanderson
Understanding The Perceptions Of Producers Regarding The Ogallala Aquifer Use: A Survey Report (2022), Jonathan Aguilar, Amariah Fischer, Matthew R. Sanderson
Kansas Agricultural Experiment Station Research Reports
This survey asked producers in the Ogallala aquifer how they view their role in groundwater use, what they see as the consequences of groundwater depletion, and why they believe groundwater should be conserved. Producers were also asked about their worldviews and values. Together, these questions help provide an understanding of the cultural state of the Ogallala aquifer, especially as it pertains to groundwater use.
Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani
Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani
Kansas Agricultural Experiment Station Research Reports
Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …
Comparison Of Static And Active Downforce On Corn At The Kansas River Valley Experiment Field In 2020, E. A. Adee

Uniformity of plant spacing and emergence have been shown to be significant contributing factors to increasing corn yields. Improved seed meters that offer very precise seed drop have been available on planters for a number of years. However, uniformity in plant emergence continues to be a challenge, especially with reduction of tillage and in fields with variable soils. Correct, consistent depth is critical for uniform corn emergence. By keeping the gauge wheels on the ground, consistent depth is achieved. An active downforce system, such as Precision Planting’s DeltaForce, applies hydraulic downforce or lift to the row unit. With a Precision …

Using A Sprayable Biodegradable Polymer To Reduce Soil Evaporation In Greenhouse Conditions, J. Flory, J. Grane, A. Patrignani

Sprayable biopolymer membranes (SBM) is an emerging mulching alternative to increase horticultural and agricultural productivity by reducing soil erosion and evaporative losses. The SBM is usually applied in liquid form directly to the soil surface where the polymer molecules form a thin biodegradable film. In order to test this technology, an experiment was performed in greenhouse conditions with the goal of quantifying the impact on soil evaporation rate and biomass accumulation in winter wheat.

Soil erosion reduces topsoil depth. In areas with a claypan, removal of productive topsoil reduces crop yield where the claypan layer is near the surface. The topsoil and claypan layer each have unique characteristics that impact crop production and within-field variability. To better understand these differences, the soil from an area of low crop yield and high crop yield were collected and laboratory tests were performed to determine the soil classification and undrained shear strength. Understanding the soil properties and the interaction between the topsoil and claypan layers may aid in understanding the process by which topsoil is being eroded.

Response Of Drought Tolerant And Conventional Corn To Limited Irrigation, I. Kisekka, F. Lamm, J. D. Holman
Kansas Agricultural Experiment Station Research Reports
With declining water levels in the Ogallala aquifer, many wells cannot supply peak irrigation water needs for corn. Emerging drought-tolerant (DT) corn hybrids could help farmers maintain yield with limited capacity wells. A knowledge gap exists comparing transgenic DT and conventional corn hybrids in yield response to water level. The purpose of this study was to compare yield, yield components, water productivity, and irrigation water use efficiency response of DT corn with cspB (DKC 6267 DGVT- 2PRO) transgene trait and conventional corn hybrid (DKC 62-98 VT2PRO) with similar maturity to full and limited irrigation. Preliminary results from the 2014 growing …
Irrigation Scheduling Based On Soil Moisture Sensors And Evapotranspiration, J. Aguilar, D. Rogers, I. Kisekka
Irrigation Scheduling Based On Soil Moisture Sensors And Evapotranspiration, J. Aguilar, D. Rogers, I. Kisekka
Kansas Agricultural Experiment Station Research Reports
Irrigation scheduling is crucial to effectively manage water resources and optimize profitability of an irrigated operation. Tools that can be customized to a field’s characteristics can greatly facilitate irrigation scheduling decisions. Soil moisture sensors and the evapotranspiration (ET)-based KanSched are two of the tools that could be implemented in an irrigated farm. Focusing on the installation of soil moisture sensors, demonstration set-ups were established at the Southwest Research-Extension Center plots in Garden City, Kansas, and in a producer’s field, each with three types of moisture sensors at different depths. Among others, this project validates the importance of moisture sensors being …
