Trey Hill of Harborview Farms is one of Kent County’s agricultural leaders, both in productivity and in openness to new ways of performing the age-old task of drawing sustenance from the soil. With his father Herman Hill Jr., Trey has been active in pioneering the use of computers, solar energy, no-till agriculture and cover crops to bring farming into the 21st century. Hill was the guest speaker at the community breakfast group meeting Dec. 16 in Chestertown, and he covered a wide range of topics, including the impact of new technology on agriculture and its effect on the environment. Here's a link to Part 1.
“There’s a lot of new technology in farming,” Hill said. He has a software system that allows him to track everything on the farm, including phone apps that let him know what all his workers are doing.
“Financially, I can track every input on every field, every output on every field. I have a list of fields, and they’re ranked by how much money I make on them. It’s very valuable to me.”
One of the largest inputs is fertilizer, which Hill said is “our number one expense.” The new precision equipment allows a farmer to determine exactly how much phosphorus, potassium, nitrogen – the three main nutrients – to apply. The new technology, he said, gives the farmer “a prescription” tailored to each field. “The cool thing about the new stuff is [how it handles] nitrogen,” Hill said. While nitrogen is an essential nutrient for growing crops, it’s also a pollutant that can leach into the watershed. And from a financial point of view, it ‘s a waste of money when the nitrogen doesn’t go into the crops. The new technology records weather data and soil type, based on satellite imagery, along with data on which hybrid is in a certain field and how that hybrid handles nitrogen. With this information, it can determine in real time exactly how much nitrogen needs to go on a given field. “It’s not perfect,” Hill said, “but it’s 100 times better than what we had before,” when standard practice was to put the same amount of nitrogen on every field.
The new technology is also being applied to poultry manure, a readily available source of phosphorus. Hill talked about a new manure spreader he just bought. “It’s low tech—you’re dumping all this manure into it, you’re not going to spend much money,” he said. But his new spreader is capable of a variable rate, allowing for the nature of the product. While manufactured fertilizers are predictable and consistent, Hill said, “Poultry litter’s a whole ‘nother beast. It doesn’t flow, you don’t know what it weighs—one truckload weighs 18 tons, the next truckload weighs 27 tons.” To deal with that, the new spreader has a built-in scale that allows it to calibrate more exactly than before how much actual nutrient gets to the crop.
The savings from the use of litter are an adaptation to the ever-changing economy. “I’ve got to cut 10% out of my costs for next year because my gross has gotten cut by 10%,” Hill said, referring to the lost markets for soybeans due to the trade war with China. For Hill, as for other Eastern Shore farmers, the balance between the latest methods and equipment and the fickle forces of the market is an everyday calculation. Given the central role of agriculture in the economy of the region, it’s good to know that our farmers aren’t taking anything for granted.
