Objective:

To observe the comparison between a conventional dry program and a complete AgroLiquid program.

Long term averages are a great way to see how fertilizer programs affect yields. By averaging yield results over several years it takes into account different soil types that the experiments were conducted on and the different weather conditions that exist from year to year.

Each year all Agro-Culture Liquid Fertilizer programs placed phosphorus, potassium and micro nutrients in a 2×2 band with the planter. High NRG-N was used as the nitrogen source and applied as a surface broadcast after planting. Conventional programs placed phosphorus as DAP (dry spread) or 10-34-0 (2×2) and potassium as potash along with micro nutrients as a broadcast spread and tilled into the soil ahead of planting. Urea (applied the same as other dry materials) or 28% UAN (broadcast after planting) was used as the nitrogen source. All programs matched fertility needs of the test area for that particular year. The North Central Research Station uses a Gandy Orbit Air spreader to accurately spread dry materials across the entire 15’ plot width. (Note: Prior to 2007 the above planter 2×2 applications were applied 1 inch to the side of the seed and at an even depth.)

Long Term Sugarbeet Fertilizer Program ComparisonsConclusions:

  • Over 9 years, there has been an average 1 Ton/A yield advantage using Agro-Culture Liquid Fertilizers compared to a conventional fertilizer program.
  • AgroLiquid nutrients provide all of the necessary nutrition needed for a great sugarbeet crop.

Objective:

Evaluate different nitrogen sources and rates on Sugarbeet yield.

All nitrogen for this experiment was applied six inches deep with the Nutri-till applicator 10 days prior to planting. Four different nitrogen sources were used. High NRG-N and N-10 were applied at 28 gal/A, 28% UAN was applied at two rates: 32 gal/A (80% rate) or 40 gal/A (100% rate) and 28% UAN + eNhance was applied at 32 gal/A (80% rate). Each nitrogen source was applied at an equivalent rate to supply the target rate/A of 120 pounds per acre.

Samples of roots were taken at harvest to run sucrose analysis for each treatment. These results of recoverable white sugar per acre (RWSA) appear on each bar in the chart below.

Nitrogen Source and Rate Comparisons for Sugarbeets

Conclusions:

  • All nitrogen sources resulted in a statistically significant yield increase over that of no applied nitrogen. However, there were no significant differences in yield produced with any of the nitrogen sources.
  • Using fewer gallons per acre of High NRG-N or N-10 produced equivalent results compared to higher gallons per acre of 28% UAN.
  • The addition of eNhance to the lower 80% rate of 28% UAN showed a very small increase in yield but not in RWSA.
  • RWSA data for these treatments showed no significant yield advantages amongst the treatments that had nitrogen applied. However the high rate of 40 gal/A of 28% may have been too much nitrogen for the yield of these beets and diminished the attainable RWSA.

Objective:

To compare Agro-Culture Liquid Fertilizer products used in a foliar program to enhance yield and quality of sugarbeets.

Applications of foliar products have sometimes proven to increase tons/A in sugarbeets at the North Central Research Station. By applying the correct fertilizer at the correct time that the crop needs it, the plant is able to improve yield. Even when small quantities of these nutrients are made readily available through the leaf surface, plants respond favorably. The following treatments were put together to supply the plant with additional nutrients above the planter time application. Foliar applications were made twice throughout the growing season at 6 to 8 leaf and again at 12 leaf stage. Samples of roots were taken at harvest for lab analysis of sucrose and the recoverable white sugar per acre (RWSA) results appear on each bar in the chart below.

Foliar Program Comparisons on Replant Sugarbeets

Conclusions:

  • This field was off to a very good early start until heavy rains flooded the area and a replant was necessary on May 21st. Therefore, lower than expected yields were achieved.
  • Both Foliar 1 and 2, a combination of Agro-Culture Liquid Fertilizer products, yielded significantly higher tons/A than the no foliar treatment.
  • The use of ferti-Rain at the North Central Research Station continues to show a yield advantage when compared to no foliar applications.
  • All foliar applications increased RWSA over the untreated check.

Objective:

Sugarbeets are a high-intensity crop requiring careful applications of nutrients to produce high tonnage
along with quality sugar content. This years experiment at the North Central Research Station compared
Agro-Culture Liquid Fertilizers nitrogen sources, High NRG-N and 28% + eNhance along with a comparison
of Pro-Germinator applied in-furrow. These were compared to a conventional fertilizer program (120-39-77). Treatments are listed on the chart below.

Fertilizer Program Comparisons in Sugarbeets

Conclusions:

  • Heaving rain following planting likely had and effect on yield. But it was decided that there was sufficient stand and replanting was not necessary.
  • All Agro-Culture Liquid Fertilizer treatments increased yield over the conventional fertilizer program.
  • In the nitrogen source comparison, 28% + eNhance showed an yield increase of just over 1 ton/A compared to High NRG-N.
  • Applying the 3 gal/A Pro-Germinator in-furrow instead of 2×2, showed a slight numerical increase (0.7 ton/A). Although no stand reduction was seen, note that in-furrow applications on sugarbeets may cause stand reduction in soils with low CEC or in dry conditions. Please consult your ACLF representative before making in-furrow applications.

Objective:

Many postemergance applications are made for disease and insect control in sugarbeet production each
season. These provide perfect opportunities to add some additional nutrition to the growing crop while
combining the applications. This experiment compared different foliar programs and timings for effect
on sugarbeet yield. The fi rst treatments were either 1 or 2 applications of ferti-Rain compared to 2
applications of a blend of Agro-Culture Liquid Fertilizer products developed for more broad-spectrum
application. Treatment descriptions and yields appear on the chart below.

Sugarbeet Foliar Program Comparisons

Conclusions:

  • All treatments yielded higher than the no foliar treatment.
  • There was no additional yield achieved with the second application of 2 qt/A ferti-Rain compared to the single application.
  • Highest numerical yield was achieved with the blend of Agro-Culture Liquid Fertilizer products, increasing sugarbeet yield over 2 ton/A.
  • Regrettably sugarbeet sugar analysis was not evaluated as we search for a source.

Objective:

To compare AgroLiquid vs conventional fertilizer programs.

This is the tenth year in comparing sugarbeet yields using AgroLiquid planter programs. This years experiment site required 5 gal/A Pro-Germinator + 6 gal/A Sure-K + 2 qt/A Micro 500 (2×2 planter) to meet soil recommendations. This AgroLiquid treatment was compared to a 100 lbs/A Potash (fall broadcast) with 10 gal/A 10-34-0 (2×2 planter) treatment and a no planter treatment. All experiment treatments received 28 gal/A of High NRG-N to supply the nitrogen needs of the sugarbeets. Plot yields were averaged across the four replications and appear as tons/A in the chart below. Sugarbeet samples were taken from each plot and sent to Michigan Sugar for sucrose analysis. Recoverable sugar is reported in pounds per acre on each bar in the chart below.

sugarbeet fert programConclusions:

  • No significant yield advantage was realized between program comparisons nor between a no planter fertilizer treatment.
  • The AgroLiquid program yielded 1.4 tons/A less than the conventional program this year. Previous year comparisons may be found in preceding research reports which shows the AgroLiquid program multi year advantage.

Objective:

To test the yield enhancing abilities of different additives to a standard sugarbeet nutrient recommendation.

Studying a soil test and knowing the field soils can lead to asking the question of: What else can be done to push sugarbeet yields to the next level? Three products were chosen to test this question in this experiment. Each was added to the base program of 5 gal/A Pro-Germinator + 6 gal/A Sure-K + 2 qt /A Micro 500 applied at planting in a 2×2 placement. The first product added was 2 qt/A of eNhance to provide an equivalent sulfur benefit of 6 lbs/A to the low sulfur test level. The second product was an experimental known as C-11 which should provide additional carbon to help alter the fertilized zone for better nutrient uptake. And the third product added was S-Calate at 1 gal/A to provide a sulfur and calcium benefit. Each gallon of S-Calate will provide an equivalent 4 lbs sulfur and 3.5 lbs calcium. Soils were wet and planting was delayed until May 29th. The late planting still resulted in very good yields which appear on the chart below. Sub samples of sugarbeets from each plot were collected and sent to Michigan Sugar for sucrose analysis and results appear on the left side of each yield bar.

Sugarbeet Fert AdditivesConclusions:

  • All three treatments with additives yielded higher tons/A and higher recoverable sugar per acre than the base program.
  • Exploring a soil test and knowing the soils can point to additional additives that may be needed to push yields to a higher level.
  • S-Calate and eNhance are two very good products to provide additional sulfur.
  • The experimental product C-11 yielded the highest tons/A and pounds of sugar per acre.

Objective:

To evaluate different nitrogen sources and their timing for sugarbeets.

High NRG-N is an excellent nitrogen source for sugarbeets. This experiment compares High NRG-N at 28 gal/A and 28% UAN at 40 gal/A. Two treatments split the application of nitrogen into a small amount of 2.5 gal/A of High NRG-N or NF-13 (an experimental nitrogen product) applied with the AgroLiquid program. The remaining 25.5 gal/A was then applied as High NRG-N broadcast to be similar to the other treatments. Sugarbeets need to get off to a fast start and it was thought that the additional nitrogen placed near the seed 2×2 would be available to the young seedling to promote the fast growth. Each nitrogen treatment was applied at a rate to provide 120 lbs/A of nitrogen per acre for a 30 ton/A yield goal. Excessive rainfall and wet soils caused planting to be delayed to May 29th. Sub samples of beets were taken from each plot and submitted to Michigan Sugar for sucrose analysis. Different nitrogen products can have an effect on Recoverable White Sugar yield. Yields per ton of beets and pounds of sugar per acre appear on the chart below.

Nitrogen Application Comparisons for SugarbeetsConclusions:

  • All 4 treatments resulted in similar sugarbeet yield.
  • The NF-13 as part of the 2×2 placed fertilizer provided the highest yield at 30.2 tons/A. It also provided the highest pounds of recoverable sugar at 8055 lbs/A. Continued testing of this experimental will continue.
  • A split application where 2.5 gal/A of High NRG-N placed 2×2 next to the seed did not improve yield, showing that a full broadcast treatment is just as effective.
  • High NRG-N continues to be an excellent nitrogen source for sugarbeets and provides very good sugar yield with a much lower application volume compared to 28% UAN.

Objective:

To compare broadcast Nitrogen sources on sugarbeets.

One of the major nutrient needs of sugarbeets is nitrogen. However, adding more nitrogen than is needed will encourage leaf growth and decrease sucrose content of the root. Nitrogen should be applied to achieve optimum canopy development for the beginning of the growing period. Then soil nitrogen levels should back off toward the end of the season to acquire the highest sucrose yield. Recoverable white sugar per acre (RWSA) is the term for sucrose yield and the major factor for quality payments to growers. In this experiment High NRG-N was compared to 28% UAN + eNhance and 28% UAN. The rates used were 28, 32 and 40 GPA respectively. Treatments were broadcast applied after planting.

Broadcast Nitrogen Comparisons on SugarbeetsConclusions:

  • No significant difference in yield was observed between the 4 comparisons.
  • The higher amount of 28% UAN did have the lowest recoverable white sugar per acre. It has been seen in the past that higher nitrogen applications can result in less recoverable white sugar per acre possibly because of the excess nitrogen.
  • High NRG-N and 28% UAN + eNhance can provide the same yield as higher rates of 28% alone while applying fewer pounds of nitrogen. Efficiency of the nutrients is the key to using less total pounds of N.
  • A rate of 32 gal of 28% + eNhance provided the highest recoverable white sugar per acre.
