we mentioned garlic last year I believe and did not mention their fertilization, so garlic would still need more than what we would like to say, and if not for crop rotation, not far from home Me, there is a corner renowned for its garlic, so we have garlic producers, and so if we have to rotate with years without garlic why would a small territory be specialized in this culture? This specialization does not date from the marketing of phytosanitary products. a peculiarity of the soil?
In "intensive", organic or conventional cultivation, garlic is fertilized.
It is the addition of manure that is everywhere discouraged. Over 5 or 6 years, in my "hay beds", I have not observed any negative effect - neither on yields (quite the contrary; even if I'm not sure!), Nor on conservation!
Volume 2 of the ITAB Technical Guide "Producing organic vegetables / Technical sheets per vegetable (the bible for organic professionals; and a reference that I use a lot, even if I don't use it at all: fertilization, treatments, preparation) from the ground, I sit on it!), predicts:
- mobilizations up to NPK 70/70/150
- exports of NPK 70/25/45
The “traditions” and therefore the “terroirs” often have multiple and complex causes: it is the encounter of people with a terroir (soil - climate - exposure)!
It may be that there is a determining influence of the soil - in particular the natural presence of sulfur (today, the absence is "erased" by fertilizers and ... pollution!). In the village next to my parents' one, we went from a limestone-type base in the Paris basin (Lorraine type) to sandy soils on sandstone from the Vosges. With us, garlic did well. In the neighboring village, with the same plants, grown the same, the result was ridiculous!
But sometimes, it was know-how: a particular "selection", jealously guarded. Or a technique ...
Often the climate ...
