“…Crop available potassium was quantified by the method of Egnér et al (1960). The Olsen P (Olsen et al, 1954) was used to evaluate the soil available P not only to the crops but also Table 2 Characterisation of the anaerobic solid digestate (DG), concerning the dry matter (DM), the organic matter (OM), the electric conductivity (EC), the organic and the total nitrogen (N o and N Total), the ratio C:N, the total phosphorus (PT), the inorganic and organic phosphorus forms (Pi and Po), the water soluble phosphorus (WSP) and the potassium, calcium and magnesium content (K, Ca and Mg) used in the field experiment ( adapted from Horta & Carneiro, 2020) 1 All the parameters analysed in the digestate are expressed on a dry matter basis excluding pH and CE. 2 Organic N. 3 to the transfer from soil to runoff waters (Horta and Torrent, 2007b).…”
