Zack Snipes, Charleston County Extension agent, and others get the same call over and over each year: how much liquid fertilizer should I be using on my strawberries and on other high-value crops? Most extension agents then pull off on the side of the road and do some calculations and then come up with an answer for their client. And then, just as quickly as that calculation is done, another call from a different grower with the same question. This process repeats for three months or so. Most liquid fertilizer recommendations are written in pounds of product per acre, making one scratch their head when the product you are using is a liquid. Zack Snipes, Justin Ballew, and Rob Last began exploring options on how they could easily calculate these recommendations for growers. They quickly came up with an excel file that gave an easy way to calculate the amount of fertilizer to use on certain crops. The only problem with what they came up with is that it was a clunky excel file and would not be easily accessible in the field for farmers. They began talks with Dr. Kendall Kirk, an agricultural engineer at Edisto Research Center. He began developing a web-based app that was easily assessable and easy to use that used our calculations. After adding fertility recommendations from the Southeastern Vegetable Crop Handbook that included how much fertilizer to deliver at varying times during a plant’s development, they also added other features like the option to add customizable fertilizer densities and crop acreage. The tool tells farmers how much fertilizer to use, when to use it in a crop’s development and is tailored to their fertilizer and acreage. There is no second guessing with the tool. You enter your parameters, and the tool spits out exactly how much to use and when. Mazzei, the worldwide leader in fertilizer injectors, reached out recently to ask if they could add the calculator to their website. In the last 30 days, the calculator has been accessed by 248 users from 34 countries and 33 U.S. states; 44 of these users were from South Carolina.
