Ashes for organic farming

Nowadays only eight percent of the cultivated field area is used for organic farming. The Ministry of Agriculture and Forestry has published the guidelines for the program of organic farming to diversify the supply and the consumption of organic food. The aim is to increase organically arable land to 20% by the year 2020.The demand of organic fertilizer products is strongly increasing. Interest in forestry by-products (ash, bark, zero fiber, etc.) for use in organic production has recently been exceptionally high. For example, development of pelleted fertilizers with zero fiber, ash and a nitrogen-containing fertilizer material is in progress.The ash fertilizer contains many valuable nutrients in fairly optimal ratios: these include phosphorus, potassium, manganese, magnesium, sulfur, zinc, calcium, boron, cobalt, copper and smaller amounts of other trace elements. Ashes contain phosphorus in large amounts, which is useful in organic production. More important nutrients than phosphorus and potassium are apparently trace elements. Neutralizing value of the ash is quite rapid comparedto many liming materials allowed in organic farming. The price quality ratio of ash as a liming material is also good.The use of clean wood ash is permissible in organic production. Peat and straw ash cannot be used in organic production because of the fact that in the EU peat is not considered a renewable resource. Restrictions include only inputs from outside of the organic farm

Wealth effects in emerging market economies

We build a panel of 14 emerging economies to estimate the magnitude of housing, stock market, and money wealth effects on consumption. Using modern panel data econometric techniques and quarterly data for the period 1990:1-2008:2, we show that: (i) wealth effects are statistically significant and relatively large in magnitude; (ii) housing wealth effects tend to be smaller for Asian emerging markets while stock market wealth effects are, in general, smaller for Latin American countries; (iii) housing wealth effects have increased for Asian coutries in recent years; and (iv) consumption reacts stronger to negative than to positive shocks in housing and financial wealth.

Observations of cosmic-ray modulations in the fall, 1984

Modulation of cosmic-ray energy spectrum was studied by using the Turku double neutron monitor. The multiplicity region of detected neutrons produced by cosmic ray hadrons in the monitor was divided into seven categories corresponding to mean energies 0.1, 0.3, 1.0, 3.2, 8.6, 21, and 94 GeV of hadrons at sea level. Based on 24-hour frequencies, a statistical analysis showed that modulation of the intensity in all categories occurred during several periods in the fall 1984. The magnitude of the variation was a few per cent

How teaching academies promote interdisciplinary communities of practice : The Helsinki Case

Universities invest in teaching academies to reward outstanding teachers. Few studies have been published about the impact of teaching academies on teaching communities. The aim of this study was to see who excellent academic teachers spoke to when they discussed teaching and learning, and what kind of community a Teachers' Academy established in 2013 offered to its Fellows. We analysed the answers to two open-ended questions from two surveys. The first survey (2013) was addressed to first-round applicants to the Academy in 2013 (N = 46, 32%) and the second (2018) to its Fellows (N = 56, 65%). In both surveys, most teachers had meaningful discussions with their close colleagues. In the second survey, the conversations with pedagogical experts merged with the discussions at the Academy. The 2018 survey also examined how well the Academy's key objectives of providing teachers with an interdisciplinary community and peer support had been achieved in five years. The Academy had become an important community for teachers, in which teachers shared mutual appreciation for teaching and collaborated across disciplinary boundaries and campuses. A challenge for a teaching academy is to support its fellows in implementing the principles of scholarship of teaching and learning, that is, carrying out scholarly educational projects and sharing the results locally, nationally and internationally.Peer reviewe
