INSTRUCTIONS

Please review these instructions. Accurate responses will help ensure your field is awarded the correct points.

Read every item under each category. More than one selection is possible, but sometimes no items will be selected.

Example: From the Cover Crops section – You planted a cover crop mix of cereal rye and tillage radish. You select “Winter hardy – single species” and “Non-winter hardy – single species.”

Completely read each statement. Several statements have more than one qualifier that needs to be met.

Example: From the Spring Tillage section – “Any full width operation, limited to a single pass, where no fall tillage was performed.”

SECTION 1: First, tell us about your cover crops, soil sampling, and nutrient management.

Cover Crops (Summer 2020 – Fall 2020) - Established growth must exceed 4 inches in height. Crop will not be harvested for grain.

Winter hardy, single species

Winter hardy, multiple species

Non- winter hardy, single species

Non-winter hardy, multiple species

Winter hardy, terminated after spring ‘21 planting

Soil Sampling (Use the previous 5-year history) Sample results must include organic matter content

Not sampled

Sampled every 4 years or less (Minimum of 1 sample per each 10 acres in the field)

GPS grid sampled, 2.5 acres or less per grid

Zone sampled, no more than 10 acres per zone

Nutrient Management (Fall 2020 – February 2021)

No nitrogen was applied in this time frame, no points awarded if soybean is the following crop

No more than 50% of the total Nitrogen Program (from all sources) was applied as NH3 with an inhibitor

Manure/Biosolid injected or incorporated

Manure applied, not incorporated

Any N containing fertilizer or manure applied when the 4-inch depth soil temperature is above 50 degrees

Manure applied ahead of a soybean crop

Nutrient Management (March 1, 2021– Summer 2021)

Spring/summer nitrogen application(s) amounted to 50% - 74% of the total Nitrogen Program(all sources)

Spring/summer nitrogen application(s) amounted to at least 75% of the total Nitrogen Program(all sources)

A nitrogen side-dress (or top-dress) application was at least 25% of the total Nitrogen Program(all sources)

Manure/Biosolid injected or applied and incorporated within 24 hours

Manure applied, not incorporated

Additional Nutrient Activities

Nitrogen rate on corn greater than 110% of the highest profitable MRTN rate*

Nitrogen rate within or less than the profitable MRTN rate range*

Nitrogen rate within 110% of the highest profitable MRTN rate*

At least 50% of actual phosphorus was banded subsurface Fall or Spring

Used Triple Super Phosphate (0-45-0) (fall applied)

Phosphorus and/or potassium rates applied based PM 1688 rates or less and/or soil samples (may be 0)

Used Variable Rate Technology application

Any fertilizer source containing nitrogen or phosphorous was broadcast on frozen or snow-covered ground

Greater than 50% of nitrogen is N credit from cover crop or previous forage crop

Manure applied prior to soybeans or any other legume crop

Rotation History

Field in 3-year rotation of different crops each of the three years (i.e. C/SB/small grain or C, SB, small grain/SB double crop)

Field in rotation longer than 3-year rotation (i.e. corn/soybean/small grain/forage).

(Note: Cover crop or forage must be grown after small grain harvest. Points are not awarded if fallow is practiced after small grain harvest; clean fallow after small grain harvest)

SECTION 3: Finally, tell us about your tillage practices.

Tillage Practices (Starting after harvest of the 2020 crop)

Fall- No tillage or low disturbance fertilizer toolbar

Fall- Strip tillage on non-HEL field and/or shank type fertilizer toolbar, and no other fall tillage performed

Fall- Any full width operation not exceeding a 3” depth

Fall- Any full width operation exceeding a 3” depth following residue harvest

Fall- Any full width tillage operation on soybean or small grain stubble, or harvest of crop residue

Spring- No tillage or low disturbance fertilizer toolbar

Spring- Strip tillage or Strip Freshener on non-HEL field, and/or shank type fertilizer bar and no other spring tillage

Spring- Any full width operation, limited to a single pass, where no fall tillage was performed

Spring- Any full width operation, two or more passes, where no fall tillage was performed

Spring- Any full width operation, one or more passes, where fall tillage was performed

Conservation and Management Practices (check all that apply on this individual field)

Saturated buffers*

Bioreactor*

Constructed wetland*

Multi-purpose oxbows*

Terraces/Contours/WASCOBs*

Grass Filter Strip/Riparian Buffer/Prairie Strips/Grassed waterways

Pollinator planting with minimized application near the area (½ acre minimum)

Conservation Plan that maintains sheet & rill erosion at or below “T”

Nitrogen rate study in cooperation with ISU, ISA, PFI, CCA or ag retailer

Have a written nutrient management plan that follows PM1688 or farm in under CCA advisement, following PM1688
