Agriculture has significant impacts on water quality. However, it is largely exempt from water quality regulations. Agricultural pollution comes primarily from sediment and nutrient runoff. Therefore, particular attention should be paid to provisions relating to soil conservation and nutrient management. Of course, establishing and protecting buffer strips along creeks and rivers and restricting livestock access to natural waterways is also critical.

Soil Conservation:

  • Tenant shall clip waterways as necessary for maintenance of soil conservation practices.
  • The Tenant will employ contour farming.
  • The Tenant will employ strip cropping.
  • No-till shall be used on designated fields.
  • A cover crop shall be seeded on corn ground harvested for silage.
  • Corn and soybean fields shall have sufficient ground cover at planting time to control erosion within soil loss limits set under the conservation plan.
  • Erosion shall be controlled in farm pond watersheds.

Crop Residue:

  • The Tenant will not burn or remove any crop residue, including but not limited to cornstalks, corncobs, leaves, straw, stubble, and stover, without the written consent of the Landlord.
  • If any fieldwork is done in the fall, at least two-thirds of the soil will be left covered with crop residue.

Nutrient Management:

  • The Tenant will haul and spread all manure on appropriate fields at times and in quantities consistent with environmental protection requirements.  At no time shall manure be spread on frozen ground or between the dates of ________________ and ________________.
  • A cover crop shall be seeded on corn ground harvested for silage.
  • No fall tillage should occur on soybean ground.
  • Crop rotation shall be followed as selected by the landlord on designated field(s).
  • Tenant agrees to test soil for residual nitrogen and phosphorus.
  • Tenant will figure credits for manure and previous legume crops before applying additional nutrients.
