I want to start a vegetable plot, my garden had 10ins of soil on top of hard compacted stones and yellow subsoil and poor drainage,i scraped off the soil with a digger and removed 12 ins deep of subsoil i put back the soil and then filled in with new topsoil i tested the new soil and found it was alkaline is there anything i can do to remedy or improve the soil for vegetable growing,the garden is 24 ft x 14 ft any help appreciated.
The soil should be lightly alkaline for vegetables, and add in a 5cm layer of well-rotted garden compost or manure to improve soil structure and fertility, and top-up each year or two years to maintain organic matter content.
