Bahiagrass (Paspalum notatum Flüggé): Overview and Pasture Management

Marcelo Wallau, Joao Vendramini, José Dubeux, and Ann Blount

Bahiagrass (Paspalum notatum Flüggé) is the most common and widely used warm-season perennial grass in Florida. Originally from South America, it is planted on over two million acres in the state and on over four million acres in the southeastern United States. The adaptation to low soil fertility and low input management makes the species one of the most popular for livestock production in Florida. It can be established by seed and is used mainly for pasture and hay production with adequate yield and acceptable animal performance. It is well adapted to the southern Coastal Plain region of the US. It establishes well in sandy soils with limited water retention and low inherent soil fertility, and is tolerant to drought, sporadic flooding, and continuous stocking.

Methods of Forage Moisture Testing

M. Wallau and J. Vendramini

Determining forage moisture is an essential procedure for estimating forage mass in pastures, determining harvesting or baling point for preserved forages, and calculating dry matter of feedstuff for total mixed rations. Target moisture for hay is between 13% and 15% (85%–87% dry matter), while it ranges from 40%–60% (60%–40% dry matter) for baleage, and up to 65% moisture (35% dry matter) for silage. Baling or harvesting at higher moisture can lead to spoilage or spontaneous combustion in hay, or butyric fermentation in silage. However, low moisture can prevent silage from properly fermenting, resulting in slow and low pH reduction for proper storage. There are several methods and pieces of equipment available to estimate forage moisture. Electronic methods such as moisture probes are quick, but they give more variable results than a microwave or forced-air heating unit such as the Koster Tester.

How to Interpret Cotton Seed Cool and Warm Germination Tests for Planting Decisions

Sudeep S. Sidhu
Other Contacts: Hardeep Singh

This publication discusses warm and cool germination tests for cotton seed quality and ways to interpret these results. A warm germination test is a good predictor of seed germination when cotton is grown under favorable conditions. Cool germination test results only provide an indication of the performance of a given seed lot when planted under unfavorable conditions. This publication is intended for growers, crop advisors, and Extension agents. Written by Sudeep S. Sidhu, and published by the UF/IFAS Department of Agronomy, April 2026.

Conducting Vegetation Surveys Using Geotagged Photographs from Smartphone and Unmanned Aerial Systems

J. S. Glueckert, A. E. Riner, James Leary, K. L. Gladding, andEli C. Russell

This publication aims to describe a simple method of importing and displaying geotagged images from unmanned aerial systems (UAS) or smartphones as vector symbols that are scaled and oriented to co-register with base layer maps in a geographic information system (GIS) without the need for processing into an orthomosaic. Instructions in this publication are for QGIS, version 3.28 LTR, but can be easily transferable to other GIS software. These methods offer an efficient and effective way to view high-resolution aerial images and photo-point image surveys in a GIS environment, allowing for basic analysis such as annotating features or points of interest.

Autonomous or Robotic Mower Use on Florida Lawns

Jaspal Singh, P. Agustin Boeri, J. Bryan Unruh, andA. J. Lindsey

Mowing is one of the most important cultural practices for the maintenance of a healthy lawn. This publication serves as a practical guide for homeowners and lawn care professionals, providing information on effectively implementing autonomous and robotic mowing technologies on lawns. Proper mowing height and intervals increase turfgrass density, leading to a healthier turf that is more competitive against weeds, diseases, and insects. Traditional mowing is generally performed with a gasoline engine or corded electric-powered lawn mowers. More recently, the use of battery-powered lawn mowers is increasing. Similarly, autonomous or “robotic” mowers have been gaining popularity for their various benefits.

Alyceclover—Summer Annual Legume

João Vendramini, Ann Blount, andJosé Dubeux

Alyceclover [Alysicarpus vaginalis (L.) DC.] is a late-growing summer annual legume native to the tropics in Asia. This warm-season legume grows erect with spreading branches and may reach a height of 60" if not harvested. Although an annual, it can reestablish each year by natural reseeding if the crop is allowed to make seed in the fall. This may be difficult to accomplish since the crop is usually cut for hay or grazed closely, which eliminates seed production. Only seed of common alyceclover is available for planting. Common alyceclover has been grown in Florida for many years for either pasture or hay.

An Extensionist’s Guide to Farm and Site Visits

Marcelo Wallau, Bob Hochmuth, Tatiana Sanchez-Jones, Mark Warren, Carissa Wickens, Prissy Fletcher, and Cheryl Mackowiak

Farm and site visits are a major component of Extension work, whether as a county faculty or state specialist. They serve various purposes, such as informal check-ins, relationship building, problem solving, sharing technology, and information collection. While time-consuming, farm visits are often the most effective method for addressing problems and developing deeper connections with stakeholders (Petrzelka, Padgitt, and Windestenn, 1999). These visits provide firsthand knowledge of the issues clients face and are effective in establishing collaborations, assessing needs, understanding agricultural production systems, and validating research applications (Oakley and Garforth, 1985; Seevers and Graham, 2012). This publication explores different facets of farm and site visits, including preparation before the visit, the investigative (problem-solving) process during the visit, and post-visit procedures. Additional resources are included to support client visits and troubleshooting.

Grass Tetany in Cattle

Y. C. Newman, M. J. Hersom, and W. E. Kunkle

This document is about grass tetany, sometimes called grass staggers or hypomagnesemia, that can be a serious problem in Florida with cattle grazing small grain or ryegrass pastures. The problem is usually confined to lactating cows. It is always associated with an imbalance in the mineral components of blood serum, especially reduced magnesium levels. In Florida, grass tetany is more severe when cattle are grazing young forage, particularly the first flush of growth during December and January. Once the forage becomes more mature, the likelihood of problems is reduced. Grass tetany is apt to appear under conditions of nutritional stress. Placing cattle on winter pasture directly after being on frosted or other low quality pasture may cause such a nutritional stress. First published in April 1997.

Herbicide Application Techniques for Woody Plant Control

Jason Ferrell, Stephen F. Enloe, andBrent Sellers

The progression of trees and other woody plants into pastures, fencerows, ditch banks, rights-of-way and other areas is a common occurrence. These woody species can be particularly troublesome and require control since they will compromise fence intregrity, impede canal drainage, interfere with transmission of electricity, and some species (such as cherry trees) are highly poisonous to livestock. The aim of this publication is to detail the techniques for the removal of woody plants.
