Is this intentional, a negative yield result on a field?
The total yield is 0 not a negative number. That was a rough year with your farming!
Yes, it was 
Use compost and alternate plantings of clover. It will greatly improve yield but not diseases.
Carrots never work for me on early planting, I always lose most of the crop to heat stress. They only work for me when I plant them to harvest right at end of fall.
