GEOGRAPHY AND HISTORY

  Wheat is the common name for members of the genus Triticum of the grass family (Gramineae) and for the cereal grains produced by these grasses. Wheat figures among the three most-produced cereals in the world, along with corn and rice. Canada is the world's sixth-largest producer and one of the largest exporters of wheat, annually producing an average of over 25 million tonnes and exporting around 15 million tonnes.  The following are problems facing wheat farming/production in Canada: Fluctuation in world prices of what has led to farmers being uncertain about their earnings turning to growing of crop with better earning.  The soils have become exhausted due to long use leading to lower quality yields.  The occurrence of summer heatwaves, frost, hailstones, prolonged winter, and drought have destroyed wheat crops leading to lower yields. Lower quality. Due to pests disease, the farmers have to spray the crop with crop chemicals hence increasing the cost of product...

  soil PH is the measure of how acidic or alkaline soil is. the more hydrogen ions in the soil the more acidic it is. the more hydroxyl ion in the soil the more alkaline it is. Soil is a naturally occurring substance forming the thin uppermost layer of the earth's surface made by the accumulation of the weathered materials on which plants and animals live. Acidic soil can be defined as those having PH  less than 5.5 in 1:1 water extract. soil acidity affect many biological and chemical reaction The following are factors which may cause the soil to become acidic: Parent materials. Rocks like granite and rhyolite are acidic rocks and on disintegration and decomposition of these rocks results in the accumulation of acid soil materials. Organic matters. The carboxylic, enolic, and phenolic materials present in organic matter debris, dissociate releasing hydrogen ions thus contributing towards soil acidity. Climate . In heavy rainfall areas, the continuous leaching process re...

  Soil texture is one of the physical properties of soil along with soil structure, soil color, soil temperature, soil porosity and others. Soil texture can be defined as the coarseness or fineness of the soil determined by relative proportion of soil particles of different diameters. The following is importance of soil texture: It influence other physical soil properties of soil like; soil permeability, soil structure, soil porosity, soil water retention capacity and so forth. Soil texture influence soil resistance to erosion. Erosion is easier to soil which are course textured as their particles are loose. It determine the relative penetration of plant roots in the soil. Where the soil particles are large, roots can penetrate more easily than they do in fine grained soil which are usually compact. Soil texture determine the infiltration rate of water into soil. Infiltration rate is easier in course textured soil compared to fine textured soil as its particles are compacted...
