The importance of maintaining mountain pastures in preserving environmental services is widely known. However, in mountainous regions, environmental and vegetation heterogeneity at the farm scale affect farm management. This study was conducted at the summer pasture of Malga Serona (northeastern Italy) to introduce a discussion of appropriate management at the farm scale. Forty botanical surveys were performed, where an herbage sample from a 100×100 cm surface was collected in each survey. The number of species, the average Landolt index, and the pastoral value (PV) were calculated for each survey. For each herbage sample, nutrient content was measured. We observed differences in botanical composition and in forage quality within the study area. We found that the PV varied from 35.6 to 52.2, NDF from 41.0 to 52.0% and crude proteine from 12.3 to 15.8%. Areas with lower PV and lower forage quality were marginal and were found in surveys with high abundance of Sesleria varia (Jacq.) Wettst., or with species usually present in under-grazed pastures. It is necessary to study botanical composition and forage quality of pastures at the farm level, and to utilize the whole grazing surface in order to maintain and restore high-quality forage.

An application of the calculated doses of mineral fertilizers, based on botanical composition of goat’s rue herbage, increases a gross yield of crude protein, crude fat and feed units to 48-57% in comparison with the control samples.

School Food Environment

This paper examines the changes to procurement for school food environments in Canada as a response to changes to nutrition regulations at the provincial level. Interviews with those working in school food environments across Canada revealed how changes to the nutrition requirements of foods and beverages sold in schools presented opportunities to not only improve the nutrient content of the items made available in school food environments, but also to include local producers and/or school gardens in procuring for the school food environment. At the same time, some schools struggle to procure nutritionally compliant foods due to increased costs associated with transporting produce to rural, remote, or northern communities as well as logistic difficulties like spoilage. Although the nutrition regulations have facilitated improvements to food environments in some schools, others require more support to improve the overall nutritional quality of the foods and beverages available to students at school.

The use and quality analysis of household compost have become very important issues in recent years due to the increasing interest in local food production and safe, self-produced food. The phenomenon was further exacerbated by the COVID-19 pandemic quarantine period, which gave new impetus to the growth of small home gardens. However, the knowledge associated with making high-quality compost is often lacking in home gardeners. Therefore, the objective of this research was to find answers to the following questions: can the quality of backyard compost be considered safe in terms of toxicity and nutrient content? Can weed seed dispersion affect the usability of backyard compost? In general, can the circulation of organic matter be increased with the spread of home composting? In this study, 16 different house composts were analysed for stability, weed seed contamination, toxic elements, and nutrient content using analysis of variance. The results of the research showed that the quality properties of the composts (including their weed seed dispersion effect) were greatly influenced by the different techniques and raw materials used. The toxicity levels, as well as the content of macro and microelements, were within the parameters of safe-quality compost. The specific macronutrient (Ca, Mg) and micronutrient (Fe, Mn) contents of the tested composts have a similar and, in some cases, more favorable nutrient supply capacity in crop production than the frequently-used cow manure-based composts. With a plan of basic education on composting, there is potential to encourage farmyard composting.

Status Assessment

Highly humic lakes are typical for the boreal zone. These unique ecosystems are characterised as relatively undisturbed habitats with brown water, high acidity, low nutrient content and lack of macrophytes. Current lake assessment methods are not appropriate for ecological assessment of highly humic lakes because of their unique properties and differing human pressures acting on these ecosystems. This study proposes a new approach suitable for the ecological status assessment of highly humic lakes impacted by hydrological modifications. Altogether, 52 macroinvertebrate samples from 15 raised bog lakes were used to develop the method. The studied lakes are located in the raised bogs at the central and eastern parts of Latvia. Altered water level was found as the main threat to the humic lake habitats since no other pressures were established. A multimetric index based on macroinvertebrate abundance, littoral and profundal preferences, Coleoptera taxa richness and the Biological Monitoring Working Party (BMWP) Score is suggested as the most suitable tool to assess the ecological quality of the highly humic lakes.
