SENSORS HELPING FARMERS BETTER UNDERSTAND CROPS

 

SENSORS HELPING FARMERS BETTER UNDERSTAND CROPS

 

We additionally have to get to some extent where we are able to execute on a routine basis, Shearer says. “The one wild card has constantly been the climate. If I knew what the weather is going to be, it'd make it plenty less difficult to manage nitrogen.”

It’s why an on-farm weather station has grown to be a critical device.

“It, in reality, empowers a farmer,” Thurow says. “We see more excessive rain occasions, and a thunderstorm may be a recreation changer. An on-farm weather station gives him a unique angle on what Mother Nature is handing over and how he may alter his plans.”

CONNECTING THE DOTS

As the sensor era keeps evolving, it’s unlikely one dimension could be able to solution all of the questions a farmer may additionally have. “The electricity comes from combining facts in new approaches,”

“When it involves connecting all of these facts via the internet of the day after today, our enterprise has a massive mission in the front of it,” Haecker says. “Sensors which might be on the system or offboard, processing skills, and cloud infrastructure … there are a lot of things that have to come together.”

SENSING ACROSS THE ACRES

PLANTER: DELTA FORCE

Brandon Hunt’s pots (Case IH 2140, Case IH 2150, and Kinze 3660) are prepared with the Precision Planting era. While records from the planters permit him to know how properly each is performing, Hunt takes the maximum away from DeltaForce. The downforce machine controls and adjusts strain immediately based totally on converting soil situations. This presents the proper planting depth on every occasion, irrespective of subject conditions.

FLOWERPOT: TRUETRACKER

Because of the rolling hills in addition to side slopes, Brandon Hunt has to contend with in western Kentucky, staying on his steerage line when planting corn within the strip may be a undertaking. 

A put-in force’s following blunders maybe five to ten instances of the tractor steering errors, in keeping with Scott Shearer, professor, Ohio State University. “Depending on the operation, that enforces could be wandering back and forth quite a chunk,” he says.

By using TMX-2050 TrueTracker, lively steerable hitches, and CenterPoint RTX, Hunt can time and again role the planter to within 1 inch on every occasion.

“We’re doing everything we can to preserve that planter within the center of the strip one hundred% of the time,” he says.

However, Shearer notes, implement steering structures are really now not but a mainstay in ag the main because of value.

WEATHER STATION: WATCHDOG 2900ET

A WatchDog 2900ET climate station feeds records directly into Hunt Farms' irrigation control platform.

CENTER PIVOTS: AQUASPY

Brandon Hunt has used both watermark and capacitance-primarily based sensors to degree soil moisture on his irrigated acres. Unlike the watermark sensor, which measures soil moisture at a single area, the capacitance-based sensor measures soil moisture and soil temperature every 4 inches along the length of the probe.

“While the watermark sensors, which have been positioned at 12, 24, and 36 inches, labored properly, I changed into looking for something special,” he says.

A couple of years ago, Hunt commenced the use of AquaSpy probes on 13 center pivots. AquaSpy is a forty-eight-inch probe geared up with sensors every 4 inches that examine moisture, nutrients, and temperature. The probe sends real-time records to Hunt, which he can get right of entry to via a telephone, pill, or laptop.

“There are a pair of things I idea we collected higher through going with AquaSpy,” Hunt says. “First, I get to look at the root intensity because it grows at some point of the season due to the fact the capacitance-based totally sensor sees in which roots are wicking away moisture. I understand if roots are shallow or if they're deep in the soil like they need to be.”

Second, the real-time information could be very truthful. “I don’t have to do loads of digging or interpolation,” Hunt says. “Because the information is straightforward to recognize, I am able to make extra timely selections on when to irrigate based on what I’m being proven.”

COMBINE: YIELD DATA

"We’ve been amassing yield statistics for a long term. It’s still quite effective data as it’s our unit of degree at harvest,” Brandon Hunt says. “Good yield records quantifies all of the things we're doing.”

Yield statistics is every other layer of statistics that facilitates decide which hybrids could be planted the following season. It also allows Hunt to evaluate the profits made in strip-until and confirm how nicely he did coping with moisture probes and his thirteen middle pivots.

PRECISE POSITIONING

As Brandon Hunt works to enhance profitability, strip-until has emerged as a pass-to solution. Besides optimizing yield, practice lowers fuel and hard work costs. There are also agronomic benefits.

Strip-till shall we the Kentucky farmer area vitamins exactly wherein they’re wished. It keeps crop residue in the region over much of the soil,

which reduces erosion and increases water infiltration. The more natural matter is preserved, and carbon dioxide stays in the soil.

“Water infiltration is absolutely essential in developing corn,” says Hunt, who additionally increases soybeans and wheat. “Wherever we don’t have the water-maintaining ability due to shallow topsoil, strip-until has enabled me to make a bigger

fuel tank.”

The practice additionally calls for a high stage of accuracy and repeatability.

“One objective of strip-till is developing a great seedbed. It is proper to place the seed along the center of the bed to maximize yield potential,” says John Fulton, professor, Ohio State University. “Research indicates that seed positioned at the edge of the strip or off the strip reduces crop yield. So it’s crucial to use the same AB strains and an excessive-accuracy GNSS correction service.”

BLENDING RTK THEN RTX

Hunt Farms began using RTK installed base stations in 2003 when it transitioned to car steer. Today, the sub-inch accuracy ensures his yield-until HDC strip-until system and planters are precisely aligned, so seed is placed on the middle of the strip.

While RTK has verified its really worth, Hunt recently started out experiencing

sign loss in some parts of the operation. To offset the problem, I subscribed to Trimble’s CenterPoint RTX. Today, he makes use of both.

“With the satellite-added correction carrier, you’ve got sub-inch accuracy in less than mins,” says Michael Bruno, channel program manager, Trimble.

As Hunt works towards banding fertilizer in the strip, reliable accuracy is even greater critical. “There is a yield penalty depending on in which that row is planted in connection with where the center of the band fertility is,” he explains.

Precise positioning the cornerstone of precision ag. But how accurate is correct enough?

“It without a doubt comes down to the belief of the operator. Depending on the operation you’re appearing, we've got tips on how accurate you need to be,” Bruno says. “Farming is all approximately margin. What seems a marginal increase in accuracy virtually can impact the lowest line.”

For instance, if you’re combining wheat and 6 inches of the cutter bar isn’t cutting the crop, it’s no longer a big deal in a single pass. If you make 100 passes over five seasons, it provides up.

“Over time, that waste would have greater than compensated for the price of better accuracy while making the operation extra efficient. You could observe that equal instance to a sprayer, a fertilizer application, or any piece of tillage equipment. Tillage is probably the most important one, especially if you practice conventional until,” Bruno says. “As farmers attempt extra accurate offerings, it’s not going they’ll flow backtrack the accuracy chain. Accuracy is addictive.”

Ultimately, in case you need to do greater extensive management, that’s in which better accuracy will pay off.

“The aim is to get every farmer within the answer that first-rate suits his operation and price range,” says Wade Stewart, market manager, ag department, Trimble.

REVOLUTIONIZING PLANT MANAGEMENT

Image-based sensors totally with synthetic intelligence in the back of them is an idea Scott Shearer believes should revolutionize the manner farmers manage their crops. See, and Spray is the first sign of tangible software in agriculture, says the Ohio State University professor.

Developed by way of Blue River Technology, See & Spray brings together cameras, computers, and artificial intelligence to understand each plant and decide the right remedy for every, usually getting to know because it is going. With pinpoint accuracy, robot nozzles target unwanted flora in actual time because the sprayer passes via the sector, applying a herbicide whilst avoiding the crop or regions without weeds.

Acquired via John Deere in 2017, the era presently identifies the differences among cotton plants and weeds of many species and sizes. It has additionally been tested in soybeans.

Deere wants a broad set of examples so as for the artificial intelligence to learn what a weed looks like and what it doesn’t look like, so See & Spray is currently being tested inside the Midwest in addition to other elements of the sector on additional crops. This wealthy intelligence will boost up deployment into numerous markets, says Julian Sanchez, director, the rising generation, John Deere.

“A gadget that may be very selective and most effective hit an area that genuinely needs it can result in 50% to 60% savings in chemical compounds by myself,” Sanchez says. “Once we get to wherein we are able to do it postemergence, we can see a ninety% savings.”

“If you look at the price of genetically modified plants, it's far in herbicide resistance,” Shearer says. “If John Deere effectively deploys the technology at scale, 50% of the fee of genetically modified vegetation might evaporate. That’s a game-changer.”

Once demonstrated, Shearer believes she will move the generation into areas like nutrient deficiency and ailment detection.
