Plant Biomass Production

Soil nutrient availability was assessed on unharvested white spruce (Piceaglauca (Moench) Voss) sites, on a recently harvested site and on 14-year-old postharvested sites stratified into four different regeneration types defined by surface soil conditions and colonizing species. These values were compared with field aboveground biomass production that had been estimated in a previous study and with biomass production of bioassay seedlings. All sites were upland and south facing. On this range of sites, laboratory net N mineralization was the soil characteristic that was the most strongly associated with plant growth in the field as well as in the greenhouse bioassay. The significance of this relationship was mainly caused by the presence of sites regenerating to aspen (Populustremuloides Michx.) which showed high plant biomass production and high soil N availability. Total soil N content, cumulative field soil temperature and soil moisture content were poorly related to N mineralization estimates and to plant biomass production. Soil temperature had an effect on N mineralization and plant growth only when sites where the forest floor had been scraped during the harvesting operations, were included in the computations. Despite a higher soil temperature, these sites showed decreased N mineralization rates and decreased plant biomass production. These results suggest that on south facing postharvested white spruce sites (i) soil temperature does not show enough variability to be an important factor controlling nutrient availability and plant growth unless the soil is severely disturbed, (ii) the rate of N mineralization is controlled by a small pool of rapidly cycling N which is poorly related to forest floor total N concentrations, and (iii) N availability and vegetation production vary with regeneration type.

Abstract Soil suppressiveness which is the natural ability of soil to support optimal plant growth and health is the resultant of multiple soil microbial components; which implies many difficulties when estimating this soil condition. Microbial benefits for plant health from repeated digestate applications were assessed in three experimental sites surrounding anaerobic biogas plants in an intensively cultivated area of northern Italy. A 2-yr trial was performed in 2017 and 2018 by performing an in-pot plant growth assay, using soil samples taken from two fields for each experimental site, of which one had been repeatedly amended with anaerobic biogas digestate and the other had not. These fields were similar in management and crop sequences (maize was the recurrent crop) for the last 10 yr. Plant growth response in the bioassay was expressed as plant biomass production, root colonization frequency by soil-borne fungi were estimated to evaluate the impact of soil-borne pathogens on plant growth, abundance of Pseudomonas and actinomycetes populations in rhizosphere were estimated as beneficial soil microbial indicators. Repeated soil amendment with digestate increased significantly soil capacity to support plant biomass production as compared to unamended control in both the years. Findings supported evidence that this increase was principally attributable to a higher natural ability of digestate-amended soils to reduce root infection by saprophytic soil-borne pathogens whose inoculum was increased by the recurrent maize cultivation. Pseudomonas and actinomycetes were always more abundant in digestate-amended soils suggesting that both these large bacterial groups were involved in the increase of their natural capacity to control soil-borne pathogens (soil suppressiveness).
