This publication addresses the influence of irrigation scheduling on water use, plant growth, and development for young pongamia trees (Millettia pinnata (L.) Panigrahi). Written by Daniel Palacios, Sandra M. Guzmán, Amir Rezazadeh, Liliana M. Cano, Lorenzo Rossi, and Alan Wright, and published by the UF/IFAS Department of Agricultural and Biological Engineering, November 2023.

Lettuce Cultivars for Insect Resistance in Southern Florida

Germán V. Sandoya, Huangjun Lu, Huangjun Lu, andAlan L. Wright

Lettuce is the most popular ingredient in salads and salad mixes consumed in the United States. Florida's subtropical climate facilitates lettuce production from fall through spring, but the warm and moist conditions are also favorable for insect proliferation and damage. Insect pests cause direct (feeding) and indirect (contamination) damages to the lettuce crop. This manuscript presents data on cultivars and breeding lines with tolerance to some of these pests. Minor Revision; 5 pp.

Strategies for Improving Phosphorus Use Efficiency in Lettuce Grown on Histosols

Gustavo Kreutz, Jehangir H. Bhadha, Guodong Liu, Marcio F. R. Resende, Alan L. Wright, Dennis C. Odero, andGermán V. Sandoya

The global demand for P fertilizers has been significantly increasing, resulting in higher costs and environmental concerns associated with eutrophication. Fertilizer expenses and environmental risks can be reduced through the implementation of sustainable strategies. This new 6-page publication of the UF/IFAS Horticultural Sciences Department compiles several strategies to improve the utilization of P fertilization in lettuce grown in the Everglades Agricultural Area.

Everglades Agricultural Area Soil Subsidence and Sustainability

Jehangir H. Bhadha, Alan L. Wright, George Snyder, andGeorge H. Snyder

This document describes the soils in the Everglades Agricultural Area (EAA) and their gradual change over time. The EAA is an agricultural region south of Lake Okeechobee, Florida, growing primarily sugarcane in rotation with sweet corn, winter vegetables, sod, and rice. The objective is to describe soil losses in the EAA because this region was converted from wetlands to agricultural use, and to illustrate how these changes affect the future of agricultural sustainability in the region.

Extraction of Soil Nutrients Using Mehlich-3 Reagent for Acid-Mineral Soils of Florida

Rao Mylavarapu, Tom Obreza, Kelly Morgan, George Hochmuth, Vimala Nair, and Alan Wright

Soil testing is a multistep process starting with the collection of a sample that adequately represents the area or field to be tested. Due to wide-ranging soil conditions across Florida and the United States, multiple soil test methods exist. During the 1970s, Florida along with several other southeastern US states adopted Mehlich-1 (M1) as the official extractant for acidic soils. The UF/IFAS Plant Nutrient Oversight Committee approved the change from M1 to M3 in 2010. Based on observations of the interpretations, the technical committee revised the M3 interpretation in March 2014. The new interpretations have been correlated with the M1 interpretations, as closely and realistically as possible, so the actual nutrient recommendations are not changed.
