Soil Fertility Improvement with Mixtures of Wood Ash and Biogas Digestates Enhances Leaf Photosynthesis and Extends the Growth Period for Deciduous Trees.

In the context of climate change, it is necessary to establish forest management by balancing more products, using less area, and minimizing environmental impacts. The use of different industrial bio-based by-products as soil conditioners in the last few decades has gain more interest, because it leads to an extended use time of these products and supports the circular economy. The aim of this study was to determine the effect of fertiliser made from cattle and pig manure biogas fermentation digestate and wood ash from two cogeneration plants, applied in different mixture ratios, to test its suitability for fertilisation of deciduous trees, using the physiological, morphological, and chemical parameters of the leaves as an indicator.

Growth and Physiological Performance of a Coastal Species as Affected by a Coexistence with , NaCl Treatment and Inoculation with Rhizobia.

The aim of the present study was to analyze the growth and physiological performance of two coexisting species, , and , under the effect of NaCl and rhizobial symbiosis. Seeds of and were collected from populations in the wild, and plants were cultivated in an automated greenhouse, two plants per container. Three basic types of planting were performed: (1) both plants were (single species), (2) one and one (species coexistence), (3) both plants were (single species).
