Soil Bed Design Can Result In Savings
November 22, 2019

From Florida to Virginia, farmers are enjoying the fruits of Sanjay Shukla’s labor. His compact-bed geometry system allows growers to plant crops in tall soil beds, and the result is thousands of dollars in annual savings.

According to information, new research by Prof. Shukla and his team shows that with savings of up to $102,000 per crop, annually, for a typical, 250-acre farm from the compact-bed geometry, farmers can buy wireless soil-moisture meters to better manage water and crop, Prof. Shukla said.

“This benefit provides growers many options to invest the savings in other aspects of modernizing their farms” said Shukla, a University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of agricultural and biological engineering. Those include automated irrigation.

With soil-moisture meters, farmers can keep an eye on how they reduce water and fuel use. They can also help prevent fertilizer from getting into water bodies, Prof. Shukla said.

In the new study, Prof. Shukla’s team put data from their prior research into computer models. Their models showed that his compact bedding design can save $20,020 to $102,570 per year for a typical fresh produce farm.

That’s because the combination of compact soil beds and soil-moisture irrigation can further reduce the amount of water and other inputs such as fuel and fertilizer.

Prof. Shukla’s raised soil beds, covered with plastic mulch, are almost six inches taller and a foot narrower than conventional soil beds most growers use to produce fruits and vegetables.

About six years ago, Prof. Shukla started designing raised beds – also called compact-bed geometry — that help reduce water, nutrients, pesticides, fuel and plastic, which are all needed to help grow tomatoes, peppers and other crops.

A few years ago, researchers studied raised beds on a commercial farm in Collier County, Florida, near the UF/IFAS Southwest Florida Research and Education Center (REC) in Immokalee.

As the compact-bed geometry research continues, Prof. Shukla said plastic’s effect on runoff is akin to that of asphalt or concrete in a city. The more area it covers, the more rainwater runs off the plastic. It also can reduce runoff of nutrients, such as nitrogen and phosphorus, said Prof. Shukla, a faculty member at the UF/IFAS Southwest Florida REC. Reduced runoff helps cut nutrients to downstream environments such as lakes and rivers.

Prof. Shukla’s new study on water conservation and cost savings is published in the Journal of Irrigation Drainage and Engineering.
