I have buildt a huegelbeet and the top layer is our soil (clay + sand alkaline) mixed with cow manure and musroom compost. First the top layer bakes, second the first seedlings emerged and they are yellow. Nitrogen deficiency? Chlorosis? Some liquid seaweed? It rained a lot.

Is the cow manure fresh or aged? Do you have mulch on top of the soil?
