We have a black walnut tree growing in the vicinity our vegetable garden. We put the tomatoes in the corner of the garden contrasting the tree. Still, the garden does not produce like we preserve hoping. Are there any specific soil amendments we can kind for this issue?

And are there any veggies that would do better - we've have carrots, radishes, lettuce, that topped out or did not grow.
Answers:    In my uncomfortable experience with black walnut trees the chemical juglone is released ancient the point of the drip line. Alot of plants died surrounded by the process of that discovery. I found a number of flower and foliage plants that be impervious but I'm not sure about vegetables. From what I've read most of them will suffer. I used alot of containers effective mine and perhaps that and raise beds where on earth you can keep the soil fresh would be your best bet. There's zilch worse than watching plants grow only to wither earlier their prime. I love trees but I didn't love that one. By the way I also recommend keeping the nuts and other tree litter cleaned up and out of your gardens and compost. All parts of the tree contain juglone to one scope or another. If you would like information on the garden plants that did succeed within my yard get the impression free to e-mail me.
Black walnut trees put out a chemical that retards growth of certain types of plants. I own one about 30 foot from my garden and most things do ok but tomatoes don't do well in the neighbourhood the tree. Check with your county extension department for more details. They can help beside soil samples. It may be a combination of the tree and the soil wanting something. For the most part my tree doesn't effect the garden much. Note, the drip file of the tree does not extend over the garden.
