Wood-ash application to forest land has been proposed as a means to compensate for increased nutrient removal at high harvest intensity. A study-plot experiment was established on a mineral soil site in Sweden to study how this measure affects soil-water chemistry. In 1995, ten treatments were applied. Here we present results from years nine to seventeen after application for eight of the treatments: control, 3×10<sup>3</sup>, 6×10<sup>3</sup> and 9×10<sup>3</sup> kg ha<sup>-1</sup> of self-hardened and crushed wood ash (WA), 150 kg N ha<sup>-1</sup> supplied as ammonium nitrate, 3×10<sup>3</sup> kg WA and 150 kg N ha-1 applied simultaneously, 3×10<sup>3</sup> kg WA with 150 kg N ha<sup>-1</sup> applied one month before the ash, and 3×10<sup>3</sup> kg ha<sup>-1</sup> of pelleted ash. Soil-water samples were collected from a depth of 50 cm. Treatment effects (<i>p</i><0.05) were detected in the electrical conductivity, pH and concentrations of K<sup>+</sup>, Mg<sup>2+</sup>, Ca<sup>2+</sup>, Al, SO<sub>4</sub><sup>2-</sup>-S and B. Elevation of K<sup>+</sup> and SO<sub>4</sub><sup>2-</sup>-S concentrations tended to cease towards the end of the study period. Effects were generally more pronounced with increasing ash dosage. No difference between the treatment 150 kg N ha<sup>-1</sup> and control was detected. Despite the high solubility of the ash, effects on the soil-water chemistry could still be detected nine to seventeen years after application.

The investigations were conducted in the frame of EU Research project Wood for Energy – a Contribution to the Development of Sustainable Forest Management (2001–2005). The integrated wood ash experiment was set up in a 38-year-old Scots pine (Pinus sylvestris L.) stand on Arenosols in SW part of Lithuania. Raw (not hardened) wood ash and nitrogen fertilizers were applied in 6 variants: 1.25 t ash/ha; 2.5 t ash/ha; 5.0 t ash/ha; 180 kg N/ha; 2.5 t ash + 180 kg N/ha and control (no treatment). The changes of soil pH, the content of some nutrients, heavy metals in Arenosols and soil solution, the abundance of ammonifiers, nitrifiers and denitrifiers in forest floor and mineral topsoil after the application of wood ash are presented and discussed in this paper.

Abstract The addition of lime and gypsum to wood ash and straw ash were used in the studies. The subject of the study was estimation of the fertilization effect of biomass, ash, gypsum and lime on the content of macro- and microelements in soil and grain of spring wheat. The experiment was carried out in 2016 in the West Pomeranian Voivodeship in Poland. The study compared three factors: wood ash of deciduous and coniferous trees and cereal straw ash (I. factor), two types of ash additions: lime or gypsum (mixture composition: 60% ash and 40% lime or gypsum) (II. factor), three doses of ash with lime or gypsum mixture: 2, 4, 6 Mg·ha−1 and control (III. factor). The analysis of the microelements contents (copper, chromium, nickel and lead) in the soil shows that the application of fertilizer in a form of wood or straw ash as well as PROFITKALK lime or SulfoPROFIT gypsum did not exceed the threshold values for the soil from the first group of land specified in Regulation of the Minister of the Environment of September 1, 2016 on the manner of assessing the pollution of the earth’s surface. After application of biomass ashes (wood or straw) an increase of some macroelements (potassium, phosphorus and calcium) in the soil was observed. The experiment did not reveal any influence of applied fertilization in the form of wood or straw ash nor PROFITKALK lime nor SulfoPROFIT gypsum on changes in iron, manganese and zinc abundance in grains of spring wheat.

The aim of this research is to evaluate the influence of wood ash as an additive fertilizer to forest soil and growing blueberries (Vaccinium myrtillus L.) in terms of metallic element content. To evaluate the effect of wood ash on the forest ecosystem, was selected two forest areas which was fertilized with a certain amount of wood ash (bottom ash and fly ash). The selected forest areas were divided into two types of sampling plots (fertilized with ash and control). Obtained results showed that in the bottom ash dispersion area the concentration of Ca, K, Ni, Cu is almost twice higher in the fertilized plots than control plots. In the blueberries, metallic element content is similar and does not depend on the type of sampling plot.

The study was conducted at the Teaching and Research Farm of the Department of Soil Science Chukwuemeka Odumegwu Ojukwu University, Igbariam Campus. The treatments studied were paper ash (PA) and wood ash (WA) of rates 4.8 kgha-1 respectively and calcium carbonate (CA) of rate 120g (equivalent of 300kgha-1) and control (CO). The experiment was laid out in a randomized complete block design (RCBD) and was replicated four times. Data collected were subjected to analysis of variance and treatment means were separated using LSD at 5% alpha level. The result recorded for the study showed that root and pod weight of bambara groundnut were not significant among the treatments but values obtained from treated plots were better than the untreated plots. Soil properties tested were greatly improved by the lime materials when compared their values on the control soil. Hence the results indicated that the lime materials especially the wood ash and paper ash could be ideal for famers as they are cheap affordable and available since it has proved through this study that these lime materials could improve crop yield and soil nutrient status and characteristics.

Five treatments were established: wood ash (10 000 and 5000 kg/ha), peat and wood ash mixture (10 000 and 5000 kg/ha) and control (unfertilized field). Results of analysis showed that the pH of peat in the cutaway peatland was before treatment 3.5 and it rose after fertilization by up to 0.7 units by the end of the first growing season. The treatment with 10 000 kg/ha of wood ash gave the best results: the annual height increment of Silver birches during the first growing season after fertilization was 4.5 times higher and that of Scots pines 1.1 times higher than control. In the second growing season after fertilization the increment was respectively 16.3 and 3.3 times higher than control. The root collar diameters of Silver birches were 4.4 time larger these of Scots pines 2.1 times larger than control. Scots pine needles were 2.2 times longer than control and the leaf area of the Silver birches was 6 times larger than control, which also shows a positive effect of fertilization. Peat ash treatment was also favourable, although its effect was much smaller than the effect of wood ash.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.
