Soil tests

1.Soil forming factors 1) Climate- The climate of the Pullman series leans on the side of ustic and is in fact a Paleustoll, but can boarder on aridic at times. Ustic is an intermediate between udic and aridic with the winters being relatively dry, and the growing season is characterized by plant available moisture between significant periods of drought. The Pullman series meets this descriptions, in that it’s driest periods lie between July and August, and then December through February, with…

What is biodiversity? Introduction Biodiversity is defined as the variety of life on Earth at all its levels and includes genes to ecosystems, as well as the ecological and evolutionary processes that sustain it (Cardinale, 2012). The Earth’s biodiversity has long been a source of wonderment and scientific curiosity, but is increasingly becoming a source of concern. The sheer diversity of life is of inestimable value. Biodiversity has a number of functions on Earth, from providing a foundation…

on the steepest slopes the support for plant life is very low. Steep slopes produce high levels of soil erosion that results in a lost of organic materials and essential nutrients needed for plant growth. Along with slope is exposure of sunlight on vegetation that can also vary growth outcomes. Slopes facing different directions may have similar precipitation amounts but direct sunlight can cause soil moisture to evaporate quicker that then forms a dryer, shady slope. However other…

As plants adapted to life on land, they had a few challenges in the new environment. The challenges when first on land were that they did not dry out as they were exposed to air, even when close to a source of water. Also on land they needed the structural support that water gave them. Also they had to find another way to filter sunlight as air does not filter out the ultraviolet rays of sunlight. Also the male gametes had to find new strategies to reach the female gametes as swimming was no…

The easiest way to explain transpiration is to think of it as plant evaporation. Transpiration as a whole is the general cycle for water regarding plants, this includes the movement of water throughout the plant itself and the movement of water leaving the organism. However, most definitions of transpiration focus on aerial parts such as the stomata on the leaves. The adhesion and cohesion of water is something very important to life. It is these properties that allow the movement of water…

derived from the Latin word nūtrīre which means ‘to feed, nurse, support and preserve.’ In other words, it’s really important to nourish your body with the right nutrients to support and preserve your health. While plants get their nutrients from the soil, we get ours from the foods we eat. Yet many of us don’t consider whether or not the foods we put into our bodies are full of healthful nutrients or not. We’re more concerned with taste and if we can microwave and eat the food in under 6…

practicals in the laboratory. The data were used to identify and classify soils for engineering applications. The data were tabulated using Unified Soil Classification System (USCS) method, which is non-laboratory test and 2 classification of soils based on laboratory test. The two laboratory test classify soil methods are Classification of soil based on particular size distribution and Classify soil based on Atterberg Limits. The soil samples from sites known as bore hole and called BH1, BH2,…

DROUGHT ADAPTATIONS IN KENYA INTRODUCTION The Lancet commission on Health and Climate change June 2015 list four direct effect of climate change; ’Increase heat stress, floods, drought and increased frequency of intense storms”( The Lancet, 2015). Who. int (2015) describes drought as a period in the climate cycle caused by lack of rainfall that result in lack of water that then leads to food shortages. The populations mostly affected by this climate induced disaster are; people of low social…

gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things, including soil microorganisms” ( Brady, Weil 2008). Changes in atmospheric concentrations of carbon dioxide, temperature, and precipitation amounts and patterns will modify the soil plant system, and influence decomposition rates which will have impacts…

Within recent decades, there has been an experience in the decrease of the soil health and fertility around the world. There are many causes to this, which will be explained later on into this essay. This is a problem that needs to have more focus put on it because soil health and fertility is arguably the basis for all of our foods and without having healthy and fertile soil, there will be a decrease in the amount of crops produced. But not only is the amount of crops produced affected, the…
