Effects of Harvest Method on Microclimate in Florida Sugarcane

2006 Annual Research Report---Immokalee, Florida, sugarcane, crops, fields, grass. UF/IFAS Photo: Josh Wickham.The production systems for sugarcane include either green cane or burnt cane harvesting operations. Sugarcane in Florida is typically harvested with burnt cane mechanical harvesting, but there is a growing interest to better understand the effects of green cane harvest residue “trash blankets” on microclimate conditions for sugarcane growing on both organic and mineral soils of Florida, so the authors conducted a three-year study to determine the effects of each harvest method on microclimate within the surface soil profile and at a 10 cm height from the soil surface. Results are presented in this 4-page fact sheet written by Hardev Sandhu, Maninder Singh, Robert Gilbert, Kelly Morgan, Ronald Rice, Leslie Baucum, James Shine Jr., and Mike Irey, and published by the UF Department of Agronomy, April 2015.

Biology and Control of Sorghum-almum in Sugarcane (SSAGR369/SC098)

Figure 3. Sorghum-almum seedhead.Sorghum-almum is a weak, perennial rhizomatous grass. Leaves of seedlings are rolled in a bud with a fringed membranous ligule. Seedlings often resemble corn seedlings when small. Stems of mature plants are stout and erect, reaching up to 14 feet tall. Leaf blades are flat and sandpapery. Sorghum-almum is commonly found in the southern part of Florida in sugarcane fields and along ditches, canals, and roadsides. This 3-page fact sheet was written by Dennis Calvin Odero, Ron Rice, and Les Baucum , and published by the UF Department of Agronomy, January 2013.

Biology and Control of Horse Purslane and Common Purslane in Sugarcane (SSAGR368/SC097)

Figure 2. Prostrate and branched horse purslane.Horse purslane and common purslane are broadleaf weeds associated with sugarcane fields in muck (organic) and mineral soils of South Florida. Growers often confuse these two weed species with each other. However, these two species have distinct phylogenetic (evolutionary) and morphological differences.

Biology and Control of Goosegrass in Sugarcane (SSAGR367/SC096)

Figure 1. Goosegrass mat-like rosette with flattened stems radiating from a central point.Goosegrass is an annual plant that produces a prostrate, mat-like rosette with flattened stems radiating from a central point. It is often described as looking like someone has stepped in the middle of the plant, flattening it out. Because of the whitish to translucent color of the leaf sheath margins, goosegrass usually appears white to silver; this is why it is known as white or silver crabgrass. Goosegrass is found year-round in southern Florida and is commonly associated with newly planted and stubble (ratoon) sugarcane fields. This 3-page fact sheet was written by Dennis Calvin Odero, Ron Rice, and Les Baucum, and published by the UF Department of Agronomy, January 2013.

Biology and Control of Coast Cockspur in Sugarcane (SSAGR366/SC095)

Figure 4. Coast cockspur inflorescence.Coast cockspur is a relative of barnyardgrass that is native to North America. In South Florida, coast cockspur typically begins to infest sugarcane during the onset of rainfall in late spring.

Phosphorus Fertilizer Recommendations for Sugarcane Production on Florida Organic Soils (SSAGR348/SC091)

Much of the sugarcane grown in South Florida is on organic soils in the Everglades Agricultural Area, which is a phosphorus-limited system. Phosphorus loads in drainage water in the Everglades Agricultural Area are an environmental concern so it is important for sugarcane growers to use best management practices such as soil testing and to follow fertilizer recommendations. This document contains updated UF/IFAS phosphorus fertilizer recommendations for Florida organic soils. This 7-page fact sheet was written by J. Mabry McCray, Ronald W. Rice, and Alan L. Wright, and published by the UF Department of Agronomy, July 2012. http://edis.ifas.ufl.edu/sc091

Calcium Silicate Recommendations for Sugarcane on Florida Organic Soils (SSAGR350/SC092)

SugarcaneAlthough silicon isn’t an essential plant nutrient, adding calcium silicate to soils low in soluble silicon increases yield an average of 20%. This 5-page fact sheet describes calcium silicate recommendations for sugarcane on organic soils, developed using field studies at several locations. Written by J. Mabry McCray, Ronald W. Rice, and Leslie E. Baucum, and published by the UF Department of Agronomy, August 2011. (UF/IFAS Photo: Josh Wickham)
