Soil carbon sequestration is a recognized climate mitigation method, but it involves changes in the practices of more than 0.5 billion farms worldwide. Regionally customized carbon-farming programs are one way to tailor soil storage local conditions. We conducted farmer participatory research on 105 Finnish investigate how farmers approach (C) sequestration. training for basics and instructed them make Carbon Farming Plan their fields. The plans were evaluated by team experts through C...
Soil carbon sequestration has a great potential in climate change mitigation. To maximise stocks northern agricultural soils, the determinants of manure application are crucial. We quantified effect on soil organic (SOC) depending rate, proportion leys relative to annuals crop rotation, and texture. compared steady-state SOC concentration under farm-yard control treatment with no based 56 individual long-term experiments at 27 locations north 50 degrees latitude. At low rate such as 0.7 Mg...
Abstract Declining carbon (C) content in agricultural soils threatens soil fertility and makes prone to erosion, which could be rectified with organic amendments. In a 4‐yr field trial, we made single application of three different sludges from the pulp paper industry studied their effects on cereal yield, C content, fungal bacterial composition. laboratory rainfall simulations, also amendments susceptibility erosion nutrient mobilization clay‐textured by measuring quality percolation water...
Cover crops (CCs) are a diverse group of species that sown simultaneously or after the cash crop either as monocrops mixtures. A farmer survey with 1130 respondents was carried out aim to gain knowledge on CC used by Finnish farmers, understand how experienced farmers were them, experiences varied depending farm and characteristics, identify target groups for dissemination policy measures. The studied conventional organic farms had selected CCs registered measure in 2020 receive agricultural...
There is a great need for sustainable fertilisers and soil amendments, as current fertilisation practices negativelyaffect the environment. Pulp mill sludges (PMS) could provide means to replace made using non-renewable resources while adding slowly decomposing organic material utilising nutrients from forest industry. This study tested effects of composted lime-stabilised mixed PMS (CPMS LPMS) on wheat (Triticum aestivum) yields residual effect oat (Avena sativa) in boreal region. A...
Nitrogen (N) from agricultural systems contributes to the eutrophication of waterbodies through leaching. Incorporating organic material with a high carbon-to-nitrogen (C/N) ratio, such as mixed pulp mill sludges (PMSs), into soil in autumn could reduce amount leachable N. This study tested potential composted and lime-stabilised PMSs (CPMS LPMS) reducing concentration mineral N soil, thus risk leaching arable land boreal region using two-year field experiment. To better understand...
Early adopter-farmers form a living lab of farms that have great deal hidden knowledge about the cultivation cover crops (CCs). Understanding how early adopters use and value CCs provides valuable knowhow to be shared with other farmers. This study gathered information most common under-sown in Finland. A structured survey was used collect farmers’ experiences considering CCs’ regional suitability, growth, competition, impacts on soil cash crop yields. The respondents were both conventional...
Cover crops (CCs) have aroused a great deal of interest as multifunctional measure to improve the sustainability agriculture. Understanding farmers’ views are important for future farm-scale implementation. A farmer survey was carried out in Finland 2021 with aims gather on agronomic performance CCs, their environmental impacts and contribution climate smart agriculture, understand how CCs differed depending farm/farmer characteristics. The sample conventional organic farms that had selected...
Farmers may promote the cultivation of under-sown cover crops (CCs) in various ways without jeopardizing yield a cash crop. With this survey, we aimed to understand how Finnish farmers manage possible challenges with CCs. A farmer survey was carried out 2021. We invited 6493 who had selected CCs as registered measure answer questionnaire 20 statements (a Likert scale), and 1130 responded (17.4%). Cochran–Mantel–Haenszel test used strength association between 11 farm/farmer characteristics...
The foundation of the future economy requires a drastic increase in mining production, while timeline for opening new facilities can be prohibitively lengthy. Therefore, it becomes extremely valuable to make use existing infrastructure fullest extent possible. Often times, facility production increases are limited by capability reliably receive increased power import or operate large electrical loads without limitation. This paper describes how deployment dynamic reactive compensation with...
