Through analysis of fertilizer quality criteria according to QCVN 01-189:2019/BNNPTNT, the above two fertilizer types meet the quality of organic fertilizers
The results of testing the agronomic effectiveness as well as the economic efficiency of two new organic fertilizers on mustard greens showed that with the dosage of 3000 kg/ha/crop, the yield increased to 10 tons/ha (21.4%) ) compared with the control in two separate ecological zones and two different soil types consisting of grey soil and mixed sandy soil. The results of this study show that the above two types of organic fertilizers obtained in this study can be applied to agricultural cultivation.
