Sugarcane growth on mineral soils in Florida can often be highly variable as related to the nature of the soils. The soil factor that best relates to sugarcane growth is soil organic matter content. Very stunted sugarcane is also associated with high nematode populations, which indicate high risk of crop damage. This new 4-page publication of the UF/IFAS Agronomy Department discusses grower options for evaluating and increasing soil organic matter. Written by J. Mabry McCray and Stewart Swanson.

Elemental Sulfur Recommendations for Sugarcane on Florida Organic Soils
Micronutrient deficiencies can be important limiting factors in alkaline soils, with most micronutrients becoming less available for plant uptake as soil pH increases. This 6-page document is intended primarily for Florida sugarcane growers but may also be useful to researchers and others interested in sugarcane nutrition. It presents revised elemental sulfur recommendations for sugarcane grown on Florida organic soils along with supporting information. Written by J. Mabry McCray, and published by the UF/IFAS Agronomy Department, February 2019.

Potassium Fertilizer Recommendations for Sugarcane on Florida Organic Soils
Potassium is a primary plant nutrient that is required in large amounts by sugarcane. About 74% of the 400,000 acres of Florida sugarcane is grown on organic soils in the Everglades Agricultural Area. Potassium is not a component of organic matter and virgin Histosols contain very low concentrations of K, so release of K through mineralization of organic matter in these soils is not an adequate K source for plant growth. This 7-page document presents revised potassium fertilizer recommendations for sugarcane grown on Florida organic soils along with supporting information. Written by J. Mabry McCray, and published by the UF/IFAS Agronomy Department, February 2019.

Nitrogen Fertilizer Recommendations for Sugarcane Production for Sugar on Florida Sand Soils
Sands used in sugarcane production in Florida have low levels of organic matter, silt, and clay, and they provide little N through mineralization of organic matter and possess a low capacity for N retention as a result. Because these soils are highly leachable, N must be managed well to ensure adequate nutrition for the crop as well as protection of groundwater. This new 4-page fact sheet is part of the Sugarcane Handbook, and it discusses sand soils used in sugarcane production, sugar yield response to nitrogen, and revised nitrogen recommendations. Written by J. Mabry McCray, Kelly T. Morgan, and Les Baucum, and published by the UF Agronomy Department, February 2016.

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)
Although 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)
