Tässä oppaassa käsitellään viljelykierrolla saatavia hyötyjä. Viljelykierrolla on suotuisa vaikutus maan rakenteeseen ja se vähentää kasvitautien, rikkakasvien ja tuhoeläinten määrää kasvustoissa. Tarkastelussa kevätöljykasvit, syysviljat, kevätvehnä ja peruna ovat parhaita esikasveja muille viljelyskasveille. Näiden jälkeen viljeltävien kasvien hehtaarisadot nousivat parhaimmillaan yli 500 kg. Öljykasvi esikasvina saattaa parantaa kevätvehnän ja ohran laatua. Säästä johtuvien epävarmuustekijöiden takia on vaikeaa antaa yksiselitteistä ohjeistusta typpilannoituksen vähentämiseksi muiden kuin palkokasvien jälkeen. Tämä opas on osa TEHO Plus -hankkeen tuottamaa materiaalia viljelijöiden ja neuvojien käyttöön, mikä täydentää hankkeen laatimaa Maatilan ympäristökäsikirjaa.

J. H. Erkko Juhana Heikki (Johan Henrik) Erkko f. 16.1.1849 i Orimattila d. 16.11.1906 i Helsingfors J.H. Erkko var en av den samtida nationella väckelsens centrala lyriker. Erkko utbildade sig till lärare vid seminariet i Jyväskylä och inledde sitt författarskap i en ljust idealistisk anda. Han skrev gracila dikter i folkvisestil, ideologiskt laddade av nationalitetsidén. Många av Erkkos fosterländska dikter har börjat leva sitt eget liv oberoende av sin författare, och så gott som förvandlats till allmän egendom. Till hans kändaste dikter hör ”Kansalaislaulu” (sv. Medborgarsång), ”Hämäläisen laulu” (sv. Tavastlänningens sång) och ”Jouluaatto” (sv. Julaftonen, populär finsk julsång som inleds ”No, onkos tullut kesä/nyt talven keskellen?”). I sina dramer behandlade Erkko även sin tids samhälleliga problem och sina religiösa uppfattningar.

Objective of the thesis is to create a value based pricing model for marine engines and study the feasibility of implementing such model in the sales organization of a specific segment in the case company’s marine division. Different pricing strategies, concept of “value”, and how perceptions of value can be influenced through value based marketing are presented as theoretical background for the value based pricing model. Forbis and Mehta’s Economic Value to Customer (EVC) was selected as framework to create the value based pricing model for marine engines. The EVC model is based on calculating and comparing life-cycle costs of the reference product and competing products, thus showing the quantifiable value of the company’s own product compared to competition. In the applied part of the thesis, the components of the EVC model are identified for a marine diesel engine, the components are explained, and an example calculation created in Excel is presented. When examining the possibilities to implement in practice a value based pricing strategy based on the EVC model, it was found that the lack of precise information on competing products is the single biggest obstacle to use EVC exactly as presented in the literature. It was also found that sometimes necessary communication channels are missing and that there is simply a lack of interest from some clients and product end-users part to spend time on studying the life-cycle costs of the product. Information on the company’s own products is however sufficient and the sales force is capable to communicate to sufficiently high executive levels in the client organizations. Therefore it is suggested to focus on quantifying and communicating the company’s own value proposition. The dynamic nature of the business environment (variance in applications in which engines are installed, different clients, competition, end-clients etc.) means also that each project should be created its own EVC calculation. This is demanding in terms of resources needed, thus it is suggested to concentrate on selected projects and buyers, and to clients where the necessary communication channels to right levels in the customer organization are available. Finally, it should be highlighted that as literature suggests, implementing a value based pricing strategy is not possible unless the whole business approach is value based.

Finland, other Nordic countries and European Union aim to decarbonize their energy production by 2050. Decarbonization requires large scale implementation of non-emission energy sources, i.e. renewable energy and nuclear power. Stochastic renewable energy sources present a challenge to balance the supply and demand for energy. Energy storages, non-emissions fuels in mobility and industrial processes are required whenever electrification is not possible. Neo-Carbon project studies the decarbonizing the energy production and the role of synthetic gas in it. This thesis studies the industrial processes in steel production, oil refining, cement manufacturing and glass manufacturing, where natural gas is already used or fuel switch to SNG is possible. The technical potential for fuel switching is assessed, and economic potential is necessary after this. All studied processes have potential for fuel switching, but total decarbonization of steel production, oil refining requires implementation of other zero-emission technologies.
