Belowground climate change responses remain a key unknown in the Earth system. Plant fine-root response is especially important to understand because fine roots respond quickly to environmental change, are responsible for nutrient and water uptake, and influence carbon cycling. However, fine-root responses to climate change are poorly constrained, especially in northern peatlands, which contain up to two-thirds of the world’s soil carbon. We present fine-root responses to warming between +2 °C and 9 °C above ambient conditions in a whole-ecosystem peatland experiment. Warming strongly increased fine-root growth by over an order of magnitude in the warmest treatment, with stronger responses in shrubs than in trees or graminoids. In the first year of treatment, the control (+0 °C) shrub fine-root growth of 0.9 km m−2y−1increased linearly by 1.2 km m−2y−1(130%) for every degree increase in soil temperature. An extended belowground growing season accounted for 20% of this dramatic increase. In the second growing season of treatment, the shrub warming response rate increased to 2.54 km m−2°C−1. Soil moisture was negatively correlated with fine-root growth, highlighting that drying of these typically water-saturated ecosystems can fuel a surprising burst in shrub belowground productivity, one possible mechanism explaining the “shrubification” of northern peatlands in response to global change. This previously unrecognized mechanism sheds light on how peatland fine-root response to warming and drying could be strong and rapid, with consequences for the belowground growing season duration, microtopography, vegetation composition, and ultimately, carbon function of these globally relevant carbon sinks.

Fine Root Growth

Although significant advances have been made in understanding terrestrial carbon cycling, there is still a large uncertainty about the variability of carbon (C) fluxes at local scales. Using a carbon mass-balance approach, I investigated the relationships between fine detritus production and soil respiration for five tropical tree species established on 16-year-old plantations. Total fine detritus production ranged from 0.69 to 1.21 kg C·m–2·year–1 with significant differences among species but with no correlation between litterfall and fine-root growth. Soil CO2 emissions ranged from 1.61 to 2.36 kg C·m–2·year–1 with no significant differences among species. Soil respiration increased with fine-root production but not with litterfall, suggesting that soil C emissions may depend more on belowground inputs or that both fine root production and soil respiration are similarly influenced by an external factor. Estimates of root + rhizosphere respiration comprised 52% of total soil respiration on average, and there was no evidence that rhizosphere respiration was associated with fine-root growth rates among species. These results suggest that inherent differences in fine-root production among species, rather than differences in aboveground litterfall, might play a main role explaining local-scale, among-forest variations in soil C emissions.

Leaf Composition

The effects of N and K fertilizer applications on yield, leaf mineral composition and fruit quality were studied at four locations in commercial cranberry plantings in experiments of 3 yr duration. Nitrogen applications at all locations increased leaf K content in the 1st and 3rd yr and decreased leaf Zn content at one location in the 2nd yr. Potassium applications increased leaf K content in all 3 yr of the experiment and decreased leaf Mg in the 2nd and 3rd yr. A significant location × N × K interaction influenced leaf K composition in the 3rd yr. Yield and fruit quality variables depended upon location but did not respond significantly to fertilizer application.
