000256134 520__ $$aApplication of biogas-residues as fertilizers may promote enhanced cycling of nutrient resources. Plants obtain water and mineral nutrients from the soil due their capacity to develop extensive root systems. However, soil compaction may restrict deep root growth. Thus, we evaluated the effects of the biogas-digestate applied as a fertilizer on root architecture, rhizosphere pH, nutrient uptake and biomass development of maize growth when subjected to soil compaction, in comparison to NPK fertilizer application and noncompacted soil condition. Experimental factors were: fertilizers - biogas-digestate (40 Mg ha-1), NPK (equivalent amount) and biogas-digestate (20 Mg ha-1) + NPK (equivalent amount); and soil compaction or non-compaction. The upper compacted layer (25 cm) received an equivalent pressure of 1.2 kg cm2. The biogas-digestate (elemental composition: 41.1% C, 3.2% N, 1.5% P and 3.8% K) was composed of maize silage as the major feedstock, and minor amounts of chicken manure. Fertilizers were mixed into the soil (50%v. arable field soil + 50%v. peat substrate). Plants were grown for 28 days under greenhouse conditions (16h per day of light period, day/night temperature of 22°C/17°C and 60% of humidity). At harvest,the measurements included: shoot and root dry mass and nutrients content (C, N, P and K); leaf area; root architecture; and soil elemental analyses. Rhizosphere pH was measured with planar optodes along the experimental period. Preliminary results showed variation of the rhizosphere pH along the experimental period for all treatments. The lowest rhizosphere pH (4.2) was observed for the biogas-digestate + NPK/soil compaction treatment and the highest rhizosphere pH (5.3) was observed for the NPK/soil compaction treatment. Similar shoot and root biomass and nutrient uptake were observed between the treatments. Thesefindings can enhance our understanding of rhizosphere pH dynamics and root architecture subjected to soil compaction aiming to improve soil fertilization practices.
