Green Manure - Potential Soil Benefit for Growing Maize
Original language description
A two-year field experiment was established with lacy phacelia (Phacelia tanacetifolia) grown as green manure or as a freezing out intercrop for maize. The experiment was established in a warm maize-growing region in Čejč (48o56'13.573"N, 16o56'53.571"E) in South Moravia, Czech Republic. In both years before planting phacelia (late July) we applied 30 t/ha of digestate from the biogas station. The total dry matter yields of the aboveground and underground biomass of phacelia in early December were high - 7.97 t/ha (2013) and 10.52 t/ha (2014). The height of the plants ranged between 70 and 120 cm. The underground biomass (roots) and aboveground biomass (stems) was 6.7-13.9% and 86.1-93.3%, respectively. To achieve these high biomass yields the biological sorption of nutrients by phacelia plants was very high (the sum of N, P, K, Ca, Mg, S, Zn, Mn, Cu, Fe): 814 kg/ha (2013) and 933 kg/ha (2014) and it also limited leaching of the nutrients in the soil profile during winter. In spring we saw a gradual decomposition of phacelia residues into which maize was planted and also the anti-erosion effect of phacelia, thus complying with the terms of GAEC 2. We can conclude that the decisive factor for growing phacelia is the date of sowing (optimal is late July to mid-August), the sum and time of rainfall during vegetation (with an emphasis on the time of germination and emergence), and by extension the sum of effective temperatures which the plants need for their growth and development. If all these conditions are met we can expect high yields of dry matter of the phacelia biomass with all the positive phenomena - anti-erosion effect, source of primary soil organic matter (carbon) and nutrients available for the following crop.
