FIPA EKOLOJIK TARIM FIPA EKOLOJIK TARIM Nitro - N encourages the formation of green parts (shoots, leaves) in all plants, allowing the plant to benefit more from the sun with photosynthesis. Thus, plants synthesize more nutrients and this leads to an increase in yield. When nitrogen is given to plants less or lack thereof, vegetative development slows down, grain and fruit yield decreases.
