Intersee ft of legumes usually occurs when the pastureland or <br />hayland is dominated by grasses, and the producer wants the benefits of a grasstlegume mix <br />and/or more production. <br />Another advantage of the interseeding of legumes into existing grass pastures or hayland, is that <br />broadleaf herbicides can be used to control broadleaf weeds in the grass stands for a few years, <br />before intetseedmg the legumes, which are susceptible to the aforementioned herbicides. <br />It is less common to interseed grasses into existing pasture or hayland, unless the initial <br />gerzzuinatia:u and establishment is poor and further tillage operations arc deemed unnecessary <br />Seedbed preparation is expensive, and f uthermore, it dries out the soil and brings new wood <br />seeds to the soil suzface; so if the initial seeding is spotty and there is a lot of bare ground, then <br />an interseedmg of grasses and/or legumes may be effective. Interseeding grasses into a grass <br />stand tends to be less effective than interseeding legumes into a grass stand, but successes of the <br />former are not unheard of <br />Myou have questions or would like to discuss this topic further please contact me. <br />Sincerely, <br />A lt, & <br />Jim Boyd, MRCS Resource Conservationist <br />The N - I Rarer— C wwwwion'. -- L- rotI in pwoWxW W Mr M Mnarloaa Paapia <br />ID cawrw a" Suebm aralr" raaorroaa on v kwift.
