Starting with a depleted soil piece of ground and wishing to get a nice yield of Sweet potato we will need to build the soil fertility up. With the Bio-digester Chicken Compost being very productive this is a great opportunity to utilize the product available.
The starting process of opening up the soil and removing some stones that were 100 – 150 mm down. Dug through again and then adding three wheel barrows of compost and turning it in.
I then added another four wheel barrow loads of compost and left it on top.
The compost I am using is the out flow from the bio-digester that has sawdust added and then processed by chooks.
I have added a lot of compost to the garden bed however I am not necessarily expecting a bumper crop. The yield that I am wanting is a reasonable harvest of sweet potatoes and a left over soil that is on its way to becoming deep and fertile. I can be extravagant with the compost because I have set up a system that produces a good sized wheel barrow load per day. And I have to use it or I will end up with a “pollution” of compost. A great system I think.
Then with a nice thick layer, five wheel barrow loads of mulch, I planted in the sweet potato cuttings.
One of my most favorite gardening jobs, building up garden beds!!
