Higher yield starts with sound agronomics.

What makes Seed Hawk the leader in emergence? It’s our deep knowledge of agronomics. We understand that getting the best crop starts with shallow, accurate seeding and optimum fertilizer placement.

 

 

 

Shallow, accurate seeding.

We’re strong believers in the value of minimum tillage. First and foremost, less soil disturbance means that fields retain more moisture, close to the soil surface. Seeding into this moisture helps speed germination. The result is quick, even emergence and a crop that will better compete with weeds. As the crop grows, staging for herbicide and fungicide applications is easier, and maturity across entire fields is more even, which makes for an easier harvest.

Shallow seeding on firm, moist soil results in uniform emergence and vigorous growth.

These wheat and canola seedlings were seeded less than an inch deep, and they have a healthy dark green color and a vibrant root system. This is a result of accurate, shallow seeding and side band fertilizer placement.

 

 

Controlling seeding depth improves yield.

The benefit of controlled, shallow seeding doesn’t end with ease of harvest – it also affects the bushels you put in the bin.

Optimum fertilizer placement.

The second pillar of precision agronomics is precision fertilizer placement, which focuses on feeding the crop, not the weeds. This practice makes more nutrients more readily available to plants when they need them most. Read more about fertilizer safety.

Here, we are showing the effects of precision phosphate placement in canola. Phosphate can be safely side banded in crops such as canola, flax and peas and still generate a popup effect, something that banding phosphate between the seed rows cannot do.

Roots have an affinity for the areas in and below the fertilizer band.

 

Independent research supports precision fertilizer placement.

Research at the Agriculture and Agri-Food Canada research station at Melfort, Saskatchewan illustrated the importance of seed and fertilizer placement in their study on early-season nutrient access and uptake in spring wheat. During the first three weeks after seeding, wheat took up 33% of its total accumulated nitrogen (N), and by six weeks had accumulated 88% of N. It’s clear that reaching full yield potential requires early-season access to nutrients, which is compromised when nutrients are placed too far from the seed row.

This point was reinforced by The Prairie Agricultural Machinery Institute, which pointed out the risk of stranded inter-row banded nitrogen. In Emergence and Yield Comparison of Mid Row and Side Banding Seeding/Fertilizer Systems (Research Update 768, July, 2007) they state:

“…if dry conditions prevail during the first few weeks following seeding, access to nitrogen by the emerging crop may be more limited with the mid-row band placement.”

Fertilizer placed in a mid or inter-row band can be stranded away from the seed, resulting in poor growth early in the season, when the crop is establishing its yield potential. At the same time, this fertilizer is readily available to weeds. Compensating for placement with higher rates isn’t the answer, because when rates are too high it can have a toxic salt effect.

With these agronomic facts in mind, Seed Hawk engineers and designers began creating tools to make seed and fertilizer placement more precise.

 

Not All Sideband Knives Are Created Equal.

We started by making our knives more precise. Seed Hawk’s Single Side Band system uses two independent, narrow knife openers to place seed and fertilizer in separate bands, guaranteeing the ideal separation between seed and fertilizer.

The trailing seed knife buries the fertilizer band before placing the seed. This simple action maintains optimum seed-fertilizer separation and eliminates fertilizer toxicity. It also does away with fertilizer placement issues common when conditions are too wet or too dry or when product is place by worn, all-in-one sideband shank openers.

In addition, our openers create a furrow effect which places seed in the optimum position for access to fertilizer, moisture and sunlight. Following close behind the openers are independent, hydraulically controlled, 4-inch-wide packer wheels. Their action packs seed to the correct depth while sealing the furrows to prevent moisture loss.

 

A Quick Look at Banding

 

Inter-Row Banding
Inter-row banding forces the roots to grow three times longer before they reach critical nutrients. It also forces growers to put excessive amounts of other nutrients with the seed.

Sidebanding

Sidebanding
With the Seed Hawk Seed Drill System, placement of the fertilizer band ¾ inch deeper and 1½ inch to the side of the seed provides just the right separation for seedling safety. This placement also provides fast, early access to the fertilizer band at just the right time in the growing season when the seedling requires rapid uptake of nutrients.

Research backs the benefits of our thinking and technology.

Farmers see the difference our precision seeding systems make and independent research backs them up.

The Seed Hawk Seed Drill System provides ideal seed and fertilizer placement and overcomes the two risks of fertilizer placement commonly found with other sideband and inter-row banding systems: fertilizer that is too close or too far away from the seed.

 

 

WADO Research

An independent trial conducted by the Westman Agricultural Diversification Organization (WADO) at Melita, Manitoba, confirms Seed Hawk safe sideband fertilizer placement. The trial looked at Seed Hawk’s sideband and Twin Wing knives in 2007 and 2008 with similar results (see graph below). The researchers found that even at high rates of nitrogen (120 pounds per acre) in canola, both systems showed no statistically significant differences in emergence compared to the unfertilized check – even in very dry, sandy soil. This indicates that fertilizer toxicity is not a concern with Seed Hawk’s sideband seeding system.

We put sound agronomic thinking to work for you.

The seed and fertilizer placement you can expect from Seed Hawk openers used as part of a complete precision seeding system will get your crops off to a safe, fast start and a high-yielding finish.

In a wide range of crops and conditions, Seed Hawk customers report an average of 10.8% higher yield when comparing their old seed drill with a more precise Seed Hawk Seeding System.
