Influence of alternative organic-mineral fertilizers application on soil organic matter and plant biomass yield

Original language description

Agriculture has been the only known and proven method to obtain food in order to meet demands of human population already for thousands of years. Quality and quantity of produced food depend on the technologies used in plant cultivation and on the condition of used land. Soil organic matter (SOM) together with soil biota form basic soil property referred to as soil fertility. Maintaining appropriate content of SOM in soils is possible by the application of organic fertilizers. However, these are not always available in required amounts. Therefore, the presented work deals with a possibility of using alternative to conventional organic fertilizers. This work investigates the effect of selected soil amendments application on the soil organic matter, which was expressed by soil indicators (Ctot, Ntot, microbial activity - DHA), and yield of a model plant (winter wheat). The influence of alternative organic-mineral fertilizers was monitored during a pot experiment. The pot experiment was realized under controlled conditions in the greenhouse and consisted of four variants: (1) control without the application of soil amendments: (2) organic-mineral fertilizer EXPLORER 21 (EXP; 6 250 kg/ha); (3) organic-mineral fertilizer ROLPOWER (RP; 3 750 kg/ha) and (4) conventional organic waste compost (CP; 30 000 kg/ha). Measured values confirmed (ANOVA, post-hoc Tukey´s HSD test, P = 0.05) the following assumptions: (1) SOM quality and quantity are positively affected by the application of soil amendment with the content of C and N in stable form. Contents of Ctot and Ntot were higher in these variants on average by more than 10% in comparison with the control variant (2). Application of alternative organic-mineral fertilizers may replace the application of conventional organic fertilizers. Measured values of selected SOM indicators were the same or higher compared to the compost application. Fertilization with EXP and RP resulted in increased microbial activity (DHA – more than by 30%) compared to the control variant. Although significantly higher doses than those recommended by the manufacturer were applied in the experiment, no negative effects on biomass production were found. Subsequently, the production of plant biomass was higher in the variant with the application of EXP and RP. These alternative fertilizers had the same positive effect on SOM as compost at the same rate of N. © 2020 International Multidisciplinary Scientific Geoconference. All rights reserved.
