Variable Rate Technology and Its Application in Precision Agriculture

Vivek Sharma, Uday Bhanu Prakash Vaddevolu, Shiva Bhambota, Yiannis Ampatzidis, Haimanote Bayabil, and Aditya Singh

The main aim of this publication is to discuss the concept of variable rate technology (VRT), and its components associated with variable rate application of water, fertilizer, and other agricultural inputs. This publication also provides an example of the control system for variable rate application of agricultural inputs in row and tree crops. Written by Vivek Sharma, Uday Bhanu Prakash Vaddevolu, Shiva Bhambota, Yiannis Ampatzidis, Haimanote Bayabil, and Aditya Singh, and published by the UF/IFAS Department of Agricultural and Biological Engineering, January 2025.

UF/IFAS Nutrient Management Recommendation Series: Carrot

Robert Hochmuth, Vivek Sharma, Thomas Obreza, and Rao Mylavarapu

Nutrient management recommendations for carrot are described according to the standard UF/IFAS recommendation format of 1) a calibrated soil test result; 2) target soil pH; 3) the "4Rs" of fertilizer management: rate, timing, placement, and source; and 4) water management factors.

Best Management Practices (BMPs): Perimeter Borders

Vivek Sharma, Kati W. Migliaccio, Brian Boman, Jemy Hinton, and Kevin Hancock

This publication addresses perimeter borders as a best management practice. Written by Vivek Sharma, Kati W. Migliaccio, Brian Boman, Jemy Hinton, and Kevin Hancock, and published by the UF/IFAS Department of Agricultural and Biological Engineering, revised May 2021.

Mobile Drip Irrigation (MDI): Benefits and Challenges for Its Adoption and Use

Bhimsen Shrestha andVivek Sharma

Overhead sprinkler irrigation is one of the most widely used methods in agriculture. However, sprinkler systems can lead to significant water loss through evaporation and wind drift, especially in hot or windy climates. To address these challenges, mobile drip irrigation (MDI) has emerged as an innovative alternative. This publication presents a comprehensive overview of the mobile drip irrigation (MDI) system. It explains how water is distributed within an MDI system and evaluates the economic factors involved in converting a center pivot irrigation system to MDI. A practical decision checklist is included to help determine whether an MDI system is suitable for a specific field operation. Written by Bhimsen Shrestha and Vivek Sharma, and published by the UF/IFAS Department of Agricultural and Biological Engineering, September 2026.
