Application of Individual Digestate Forms for the Improvement of Hemp Production

In a two-year vegetation field experiment, the fertilizing effects of by-products from the agricultural biogas plant—a solid phase of digestate (SPD) and a liquid phase of digestate (LPD)—were studied and compared with mineral fertilization (NPK) on the biomass yield, content and nutrient uptake by...

Due to prolonged nutrient release from SPD, we can expect a smaller negative environmental impact than current fertilization practices.Jiří VelechovskýMatěj MalíkLukáš KaplanPavel TlustošMDPI AGarticle<i>Cannabis sativa</i> L.fertilizationbiogas plantssolid phase of digestateliquid phase of digestateAgriculture (General)S1-972ENAgriculture, Vol 11, Iss 1137, p 1137 (2021)
