Boom sprayer calibration using conventional methods (catching flow for certain time or distance) for large (60-90 ft; 54-72 nozzles) boom sprayers can be a time-consuming process. This short publication outlines steps to take to verify nozzle output and calibrate a boom sprayer, including tables with useful information on flow rates at multiple speeds for two common nozzle spacings and an equation for calculating rates if needed.

2022 Georgia Cotton Production Guide
The cotton production guide provides an in-depth look at cotton production in Georgia and the southeastern United States. Issues discussed include economic outlook, fertility, weed management, insect management, disease and nematode management, irrigation decisions, precision ag technology, and general agronomics of the cotton crop (varieties, PGR applications, defoliation, etc.).

Johnsongrass (Sorghum halepense) is a warm-season perennial weed in pastures and roadsides throughout central and northern Georgia. Populations may germinate from seed in spring after overwintering in the soil. However, Johnsongrass primarily emerges from dormant rhizomes in areas with a history of infestations. Rhizomes are belowground stems that produce daughter plants and storage reserves for new growth in spring. The persistence of Johnsongrass is primarily associated with extensive rhizomatous growth that enable populations to spread laterally and dominate areas by preventing desirable species from flourishing.

This bulletin describes a recommended procedure to measure soil saturated hydraulic conductivity (Ks) with a borehole permeameter and convert this value to estimates of percolation rate for on-site wastewater treatment systems. Saturated hydraulic conductivity is a fundamental hydraulic parameter for soil water flow and it is defined as the ratio of the water velocity to the hydraulic gradient. This bulletin also provides information on a computer-based program to help calculate saturated hydraulic conductivity.

These irrigation budgets, developed by University of Georgia Cooperative Extension, are estimates of the irrigation costs of a center pivot irrigation system located in southeast Georgia. Our intention is to provide flexible, user-friendly irrigation budgets with default values. That being said, the variation among different farm conditions can impact investment costs and annual costs associated with irrigation; users are suggested to modify these default values and customize their budgets according to their specific field conditions. Please consult your irrigation providers for properly designed center pivot systems that match well production to achieve your irrigation goals. This should serve as a generalized user guide for irrigation budgets and provide guidance for adjusting the default values in the budgets.

Successful lawn care requires a basic understanding of soil properties. A healthy plant starts with healthy soil. Soil is a complex relationship of soil minerals, organic matter, soil inhabiting organisms, and plants along with water and air. Understanding when and how to aerate the soil and understanding what pH is and how it affects plant health is essential for turfgrass health. This publication aims to help homeowners and landscape professionals improve soil fertility through the techniques discussed.
