Study shows crops, cows co-ex­ist cleanly

South Waikato News - - RURAL DELIVERY - By JON MOR­GAN

The ben­e­fits of in­te­grat­ing crops and cows are summed up in a new pub­li­ca­tion by the Foun­da­tion for Arable Re­search.

The three projects funded by the foun­da­tion, DairyNZ and the Min­istry for Pri­mary In­dus­tries’ Sus­tain­able Farm­ing Fund fo­cus on get­ting the best out of a range of for­age crops for dairy sup­ply, both on and off the dairy plat­form, and on us­ing crops to man­age the nu­tri­ents from cows and shed ef­flu­ent. The projects are: Crop­ping on the Wai­mate West demon­stra­tion farm, com­par­ing the pro­duc­tiv­ity of an all-pas­ture dairy sys­tem with a sys­tem com­bin­ing a pe­riod of crop­ping with long-term pas­ture.

Us­ing maize to man­age dairy shed ef­flu­ent. This showed how the en­vi­ron­men­tal risk of ni­tro­gen leach­ing could be less­ened.

Maize silage – the other side of the coin – looked at arable crop­ping se­quences for dairy sup­ply with the aim of get­ting the best dry mat­ter pro­duc­tion per hectare.

All grow­ers will re­ceive the pub­li­ca­tion in the mail in July. In the mean­time, it can be viewed on-line.
