USMARC_Field_18A_ _23D.docx

USMARC is requiring corn hybrids varieties for the 2015 cropping season. All hybrids/varieties recommended should be yield proven (no experimental hybrids) in area test plots. A description of the recommended hybrids/varieties with supporting plot data should be included with bids. Individual hybrid/variety characteristics ratings, not provided in seed guide, should be described in each field’s comment section.

Field descriptions include a minimum request for insect resistance via GMO’s. Additional or amplified events may be bid. Additional benefits of recommended hybrid will be considered when accepting or determining winning hybrid.

Hybrids/varieties selected by USMARC will be the best value for USMARC; decisions will be based on yield data, genetic diversity, GMO events, plant characteristics and price.

USMARC feed needs are significantly impacted by climate. Rotations, seed hybrid/variety and quantities are subject to pre-plant adjustments.

Small allotments of seed may be delivered in bags. Large allotments of seed should be packaged in center flow bulk seed Pro-boxes. We must be able to return any unopened/undamaged bags for refund.

Seed deliveries can be made as soon as you have been notified of selections. Deliveries need to be made by March 15, 2015.

Corn acres usage

Corn fields not identified for potential silage harvest will be harvested as either earlage or dry grain. Recommended grain harvest moisture content should be included for all hybrids.

Desirable Hybrid characteristics – Silage Hybrids

· High starch digestibility

· High NDF digestibility

· Soft kernel texture

· Slow kernel drying

Desirable Hybrid characteristics- All Hybrids

Yield- Yield consistency.

Early Season vigor – Strip till and no till seedbeds, in furrow pop-up fertilizer will be applied.

Late Season Intactness – All hybrids should have good staygreen and harvest appearance. Strong stalks and roots.

Soils –

Primary soil type of the individual fields is a Crete silt loam with 0 to 1% slopes; this soil is moderately well drained. Several fields include a percentage of a Hastings silt loam variant. Hastings silt loam areas tend to have 3 to 6% slopes and are well drained.

Most fields also have pockets of Butler and/or Fillmore silt loams. These soils are poor to very poorly drained. Individual field descriptions will note if there is a significant portion of poorly drained soils in the field.

For more detailed soil descriptions, the legal description and latitude-longitude for each field have been provided and fields may be viewed on the internet at: http://websoilsurvey.sc.egov.usda.gov

Nutrient management-

UNL recommendations are used for determining nutrient applications, a corn yield goal of 220/240 bushels or 25/27 tons silage per acre will be used to generate recommendations.

Individual field descriptions will indicate primary N source and the most recent soil test data on P, K, Mg, Ca, and Na. Soil pH, CEC, OM% is also provided.

Phosphorus is applied at maintenance levels as required. Most phosphorus is supplied by periodical applications of manure.

GMO’s-

Events not approved for export should not be bid.

For event rotation purposes, Rootworm event history for each applicable field is provided.

Planter –

John Deere Max Emerge vacuum planter, 30” rows, equipped with ProMax 40 flat metering discs. Central commodity system (CCS).

Unless otherwise specified, most seedbeds are prepared with striptill unit. Spring operation.

USMARC Field #18A & 23D. 264 irrigated acres. Likely harvested as corn silage in 2015’. A dual purpose, silage proven (will consider silage specific) 108 to 110 day RIB hybrid with above & below ground insect protection and herbicide tolerance (glyphosate and/or glufosinate).

Fields are generally moderately well drained, level to gently sloping crete silt loam soils with significant pockets of fillmore/butler soils. Preplant N source will be 32% applied via strip till. Postemerge N (32%) will be applied via sidedress and/or chemigation.

18A - P-37.25ppm, K-215ppm, Mg-243ppm, Ca-2,030ppm Na-45.25ppm, S-9ppm, Z-.8ppm OM-3, pH-6.15, CEC-14.75 meq/100g
