Maize (Zea mays L.) production requires large amounts of nitrogen (N) thatdirectly affect production cost. Poultry litter can be used as an alternative source ofN. To optimize its use, poultry litter requires technical and economic feasibilityanalyses. Crop simulation models have proven to be efficient tools to support thistype of research. The objectives of this study were to determine yield a...

Digestate contains many essential nutrients for crops, including nitrogen (N) and phosphorus (P), it can alter the biogeochemical cycle of soil functionality. This work aimed to assess fertilizing effects digestate on chemical biological properties in a field experiment eastern Portugal with two horticultural crops involving nine treatments: control without fertilization; mineral N fertilizatio...

This experiment was designed to determine the effect of spent mushroom substrate, farmyard manure, and mineral fertilization with nitrogen, phosphorus, potassium on yield quality raw material obtained from two cultivars (“Słoneczko” “De Dolj”) common thyme. Unfertilized plots thyme crops were included as control treatment. Different row spacings (30 cm 40 cm) represented second experimental fac...
