Afther the first autumn rains, during November and December, the Spanish farmers, especially in La Mancha, are preparing the seedbed to sow cereals and legumes. These tasks are very stressful because these days are very short therefore we have to work really hard from sunrise to sunset. Another possible problem is it rains frequently and we cannot work on the fields all the time.
As you can see in our pictures, we use our JD 5720 with Amazone ZA-X Perfect Centrifugal Broadcaster to spread fertilizer at working width of 18 m. We are spreading NPK 12-24-12 fertilizer and we are using about 200kg/ha. After that, we harrow our fields to bury fertilizer, this is made,finally, to prepare the soil to sow.
