Detecting In-Season Crop Water Stress to Improve Climate Resiliency

Sponsor: NC Soybean Producers Association, Inc.

Start Date: 2/01/23

End Date: 1/31/24

Abstract

The cost of soybean production is increasing. Nutrient inputs are at historically high costs at a time where there is increased variability in growing season conditions. Crops can experience multiple kinds of stresses and better information is needed on strategies that allow the crop to perform as well as possible while using a minimum of inputs. In North Carolina three of the most substantial production costs are seed, nutrient inputs, and water management infrastructure. This project further develops relationships between water stresses and nutrient uptake so that the response to stress conditions will protect the variety’s yield potential, optimize nutrients, and suggest water management approaches – addressing all the major cost centers. The larger outcome of this research and extension effort is in-season response to water challenges such that nutrient input may be reduced, applications timed to environmental stress and profitability improved. The ability to utilize UAV data to assess plant water and nutrient stress in-season as it occurs and ultimately use the data to prescribe an appropriate course of action is necessary to protect soybean crop profits. This process will provide a framework to quickly assess areas in the field and allow for corrective measures to protect the crop from climatic conditions that ultimately would cause severe yield reductions.

Sustainable Agriculture Research and Education (SARE) Program 2021 (NCSU Component: Land Summit Professional Development)

Sponsor: US Dept. of Agriculture - National Institute of Food and Agriculture (USDA NIFA)

Start Date: 7/01/22

End Date: 6/30/24

Abstract

The Rural Land Summit (RLS) is a two-pronged professional development education series - with original content support - to address matters related to farm and forest land use. One education prong is a professional credit series - assisted by NC State Office of Continuing Education - for lawyers and others across North Carolina. The second prong builds the capacity of front line contacts - cooperative extension, soil & water, etc. - to serve rural landowners and farmers and forest land managers with guidance to resources and professional assistance on land use matters. The project produces a book - The North Carolina Rural Lands Guide (RLG) - targeted to assist rural landowners not traditionally served by commodity group education programming, and thus operating at a scale not often served by risk management education outside of dedicated programming. Additional media produced will be a suite of 1) interview-based youtube videos on sundry legal topics, 2) professional-grade white papers, 3) lay narratives published on two websites - NC Farm Law (farmlaw.ces.ncsu.edu) and NC Farm Planning Portal (in development), and 4) matching powerpoint presentations. The main topic of “land use” is somewhat of a catchall - designed to capture the attention of landowners (i.e. farm landlords) and land owner/operators on a range of topics of normal concern, such as heir property resolution, property taxes, zoning and building, and environmental matters such as pesticide use, conservation program practices, leasing and farm tenancies, drainage management, access and easements (including utilities), and basic forest management and marketing.

Abstract

The cost of corn production is increasing. Nutrient inputs are at historically high costs at a time where there is increased variability in growing season conditions. Crops can experience multiple kinds of stresses and better information is needed on strategies that allow the crop to perform as well as possible while using a minimum of inputs. In North Carolina three of the most substantial production costs are seed, nutrient inputs, and water management infrastructure.

Start Date: 2/01/22

End Date: 1/31/24

Abstract

The purpose of this project is to set up a statewide soil moisture monitoring network for corn production that research and extension specialists, area specialized agents, county agents and growers can use in developing corn specific irrigation and water management protocols during the growing season based on existing soil water conditions across the state. This project will provide the initial instrumentation across the state, the cloud database, and access to the data, along with training to growers and agents on how to interpret and use the real time data for making irrigation and water management decisions during the growing season.

Development and testing of soybean management protocols for a new “SMART” water management system for increased soybean yield and quality while minimizing water use and production cost

Sponsor: NC Soybean Producers Association, Inc.

Start Date: 4/01/15

End Date: 12/31/18

Abstract

The overall goal of the project is to demonstrate and evaluate an economical system to will maximize water use efficiency and reduce energy consumption utilizing existing irrigation and drainage system. Existing or retrofitted “SMART” system capabilities allow for automated water table controls by managing drainage outlets coupled with both surface and subsurface irrigation systems. However, management protocols need to be tailored to maximize water management for all periods in the soybean growth stages (Emergence (VE) through Full Maturity (R8)). Specific objectives are: 1) Develop a comprehensive water table management protocol for soybeans to enhance soybean yield, conserve water, conserve energy and improve water quality; 2) Document soybean yields and water conservation benefits of the practice; 3) Promote plant health and increase soybean quality; 4) Reduce irrigation and management expenses by managing soil water stresses at all growth stages; 5) Demonstrate the use of the “SMART” water management system to producers on farm; 6) Conduct a cost-benefit analysis to assess the feasibility of the system
