| Question | Answer |
| If ANY of the following are present... the slope is >2 to 18%, <4" of topsoil, compaction, slow or very slow infiltration, common or few living organisms one should... | Apply cover crops |
| This should be used where water runoff from two adjacent slopes concentrates and flows at erosive rates which could create gullies (within flagged area). | grassed waterways |
| If ALL of the following are present... 0 - 2% slopes and somewhat poorly or poorly/very poorly drained soils one should apply... | drainage water management |
| If site borders a stream or water course AND any of the following are present: >2 to 18% slope, very slow infiltration one should apply... | increased setbacks/filter strips |
| Should be used when somewhat poorly, or poorly/very poorly drained soils are in a closed depression landscape position. | Blind inlet |
| If ANY of the following are present: coarse textured subsoil, slow or very slow infiltration one should apply... | fertilizer placement preventing groundwater pollution |
| If slope is >18 one should apply... | Permanent pasture or woodland (if selected, no other selection should be marked in this section) |
| If ALL of the following are present: <2% slopes, moderately coarse, medium moderately fine or fine subsoil textures, >4' topsoil, well/moderately well drained, no compation, rapid or moderat infiltration, many living organisms it is... | slight risk |
| Do not apply nitrogen to... | soybeans and alfalfa |
| Apply nitrogen to... | corn and wheat |
| Maintain phosphorus when corn and soybeans are... | 30-60 lbs |
| maintain phosphorus when wheat and alfalfa are... | 50-80 lbs |
| maintain potassium when... | crop is 200 - 300 lbs |
| maintain pH when... | it is between 6.4 - 7.9 |
| what is infiltration | how fast water enters soil from the surface |
| when infiltration is too slow it may lead to... | ponding or erosion from surface runoff and will not alloow proper soil filtration of nutrients |
| how is infiltration evaluated? | based on the texture and structure of the topsoil |
| If texture is coarse + single grained, the infiltration will be... | rapid |
| If texture is moderatly coarse + granular, the infiltration will be... | moderate |
| If texture is medium + blocky, the infiltration will be... | moderate |
| If texture is moderatly fine + platy, the infiltration will be... | very slow |
| If texture is fine + massive, the infiltration will be... | very slow |
| The more _____ and _______, the worse for infiltration | fine, massive |
| The more ________ and ________, the better for infiltration. | moderate, granular |
| If too ________ and ___________ infiltration is too rapid. | coarse, single |
| few living organisms is... | <1 per area |
| common living organisms is... | 1 to <5 per area |
| Many common living organisms is... | > or equal to 5 per area |
