Biochar and its Use in Soil: Lessons from Temperate Agriculture Authored by M Oelbermann Biochar Basics What is biochar? Biochar is a carbon-rich product that is obtained when a sustainable source of biomass is heated without oxygen. Biochar is produced in the same way as charcoal, but its intended use differs. Biochar is manufactured with a specific set of properties (e.g. adsorption properties, ion exchange capacity, low bulk density) for its use as soil amendment and/or adsorbent, whereas charcoal has specific properties (e.g. generating heat) for its use as a fuel. Humans first used biochar in the form of charcoal (as a byproduct from cooking) mixed with broken pottery, animal bones and manure in the Brazilian Amazon. This led to the creation of the Amazonian Dark Earths or Terra Preta more than 2000 years ago by pre-Columbian cultures of this region. Whether these soils were created intentionally or if they were a by-product of human settlements remains unclear. However, Terr...

Estimation of Carbon Stored in Reforestations in The Mixteca Alta of Oaxaca, Mexico Authorized by Abdul Khalil Gardezi Background and objective: Mexico is one of the countries with the highest soil degradation due to erosion in Latin America. One of the most affected areas is the Mixteca Alta of Oaxaca, Mexico which presents advanced degradation processes. Where reforestation has been implemented as a restoration strategy. Which will allow recovering some ecosystem functions, such as protection against erosion and carbon capture. Materials and Methods: In the present study, aerial biomass, aerial carbon and soil organic carbon (SOC) were estimated in reforestation of Pinus greggii of different ages (1 to 8 years) with soil clearing under two slope conditions in the northern zone of the Mixteca Alta of Oaxaca. Aerial biomass and aerial carbon were obtained by allometric equations. The organic carbon content of the soil was estimated from the soil organic matter (OM), which w...

The Effectiveness of Soil and Water Conservation as Climate Smart Agricultural Practice and Its Contribution to Smallholder Farmers’ Livelihoods. The Case of Bambasi District Benishangul Gumuz Regional State, Northwest of Ethiopia Authorized by Dereje Mosissa This study is an investigation of effectiveness of soil and water conservation practices as climate smart agriculture and its’ contribution to the livelihoods of smallholder’s farmers in Bambasi District of Northwestern Ethiopia. It was hypothesized that there is no relationship between factors contributing to the adoption of SWC technologies and a number of SWC technologies adopted, as well as there is no relationship between the number of SWC technologies used by farmers and access to the livelihood assets. In order to address the objectives, both primary and secondary data were used for the study. The study applied a non-experimental design (explanatory) to collect primary data from a sample of 270 households drawn...

Analysis of Growth Performance Data in Sheep using Linear Mixed Model Authorized by Mekonnen Tilahun The annual Ethiopian goat meat and mutton production is very low. Major causes contributing to such low meat production include slaughtering animals at immature bodyweights, poor genetic potential of the local breeds, poor feeding conditions and policy issues. Increasing the current level of productivity is essential to provide meat to the ever-increasing human population and to satisfy the huge demand of live-animal export to neighboring countries.

New Record of Long-Eared Hedgehog, Hemiechinus Auritus (Gmelin, 1770) in Sohag Governorate, Egypt Authorized by Abd El Aleem Saad Soliman Desoky Hemiechinus collaris is a burrowing and nocturnal species, recorded near water and agricultural landscapes [1,2]. This species is useful indirectly to human being as it consumes insects, termites and scorpions. While H. collaris does not damage agriculture and lives on the edge of agriculture land or near desert and this species has no conflict with human. Long-eared hedgehog avoid high heat; strictly nocturnal in summer, emerging at dusk and feed for 5 to 6 hours [2].

Use Rodents as an Indicator of Environmental Pollution Authorized by Abd El Aleem Saad Soliman Desoky Human is one of the biggest factors that cause pollution in the environment at the local or global level. At the local level, the impact of man is confined to the small environment surrounding it. On the global level, the effect of human pollution of the atmosphere resulting in global climate change. Therefore, rodents can be used as a biological indicator to assess the damage caused to the environment as a result of exposure to pollution factors that cause imbalance in the environment and affected by humans, plants and animals.

Nitrogen Fertilizer Rate and Time of Application Affected Yield and Quality of Turmeric (Curcuma longa L) at Tepi, Southwestern Ethiopia Authorized by Behailu Mekonnen Turmeric is one of the most widely grown spice crop in southwestern part of Ethiopia. However, the yield and quality of this crop is low due to many factors. In 2016/2017 main cropping season, an experiment was conducted to determine the effects of nitrogen rate and time of application on yield and quality of turmeric at Tepi. The study consists of five nitrogen rates (0, 46, 69, 92, 115 kg ha-1) and five split applications time (full dose at emergence, half at emergence + half at lag growth stage, 1/3rd at emergence + 1/3rd at lag growth stage + 1/3rd at tillering stage, 1/4th at emergence + 1/4th at lag growth stage + 1/4th at tillering stage + 1/4th at slow growth stage, and 1/5th at emergence + 1/5th at lag growth stage + 1/5th at tillering stage + 1/5th at slow growth stage + 1/5th at maturity stage )...

The Effect of Organic and Inorganic Nutrient Sources on The Growth and Seed Yield of Bambara Nut (Vigna Subterranean (L) Verdc) Variety Authorized by Getamesay Shiwenzu The research was conducted at the Teaching and Research Farm, of Federal University Wukari, Taraba State Nigeria, during the raining seasons of 2016 and 2017 to assess the effects of organic and inorganic fertilizers on the growth and seed yield of Bambara nut varieties. The treatments consisted of two varieties of Bambara nuts, (white and black varieties) and the fertilizers: organic (10, 20t ha-1 of poultry manure), and inorganic (30 and 60kgN ha-1 of Urea) with a control. These were laid out in a Randomized Complete Block Design (RCBD), with four replications.

Experience from Traditional Irrigation Management in Ethiopia. Case Study of Holetta River Authorized by Getamesay Shiwenzu The main objective of the study was to assess experience of Holetta River to traditional irrigation users. In the study both qualitative and quantitative research approaches were used. By Purposive and convenient sampling methods open ended questionnaire and unstructured interview were employed along with direct observation. The management of the river very challengeable. Access to water doesn’t account for the type of crop and its stage, land hold and distant from the primary channel. Also, farmers make unlawful acts coupled with inefficient application of community the correct the problems. On the other hand, the participation of the community on the efficient management of the river is not effective. Therefore, improving the management of the irrigation is important by involving all concerning bodies. In the future it is imperative to made capaci...
