Definition
Tilling runs the risk of erosion and exposes organic matter such that it favors the breakdown of it. |

Definition
Disking/plowing inverts soil and buries existing plants but leaves ground rough |

when using grain drills, the higher seeding rate helps compensate for... |
|
Definition
seeds that don’t germinate |
|
|
Term
some details about no-till seeding |
|
Definition
-Surface must be smooth to start -Suppress weeds/sod with herbicide -Plant directly into dead residue -Conserves moisture (better success rate) -Reduces erosion and crusting -Maintains soil structure -Reduces fuel and labor costs |
|

Definition
|
|
Term
some things to consider when controlling weeds during or after planting |

Definition
-Chemical options are limited -Mow/graze to prevent competition |
|
|
Term
some things to do when Incorporating Legumes Into Grasses |
|
Definition
-Establish the grass first -Graze or mow pasture in late summer (Aug./Sept.) -Chemically suppress the grass |
|
|
Term
why you want to establish the grass before the legumes |
|
Definition
-Less erosion -Better weed control options -allows you to control the weeds and maintain the soil and such |

|
Definition
this means you have to do the germination test and other tests on it on your own; you’re taking all the risks along with it |
