The questions the grower has are:
1. What is the nutrient value of fresh coffee grounds? N-P-K and
micronutrient values would be greatly appreciated, if anyone has knows this
2. Is there a reason why he should not apply fresh coffee grounds to soil
which will be planted to vegetables? He is concerned about potential
growth inhibition, or some otherwise unknown negative impacts.
