Humus

more suitable to apply to the soil as a fertilizing resource. Aerobic composting occurs in the presence of abundant oxygen. In this procedure, aerobic microorganisms decompose natural matter and generate carbon dioxide, ammonia, water, heat and humus, the approximately stable organic finished product. 4Although aerobic composting may create intermediate complexes, for example, organic acids, aerobic micro-organisms

efforts for composting benefit me greatly because I can use this finished material to improve my soil texture, the soil's ability to hold water, and as a fertilizer. Composting is a biological process for converting organic solid wastes into a stable humus like product. Within a compost pile, microorganisms attack organic substance, breaking it down and producing rich organic matter (Golueke,13). For this to occur, several things need to take place, two of

371). Jordahl and Karlen (1993) observed that the soil on a conventional Iowa farm had significantly less silt and clay than a similar soil from an adjacent organic farm, suggesting that the fine materials had been eroded away (p. 29). The high humus levels are responsible for the erosion resistance documented on organic farms. High levels of organic matter increases aggregate stability, which prevents erosion, allows for easier water and mechanical (such as plow and root) penetration, and better

nourishment from chemicals in solution by the German scientist called Justus von Liebig led to a decrease in the use of compost and an increase in the use of chemical fertilizers. Before this, it was believed that all plants absorbed nutrients directly from humus. This discovery led people to think that all was necessary to aid plant growth were the addition of chemical solutions. Despite this, in recent years the composting movement has regained its momentum due a vast array of factors such as the growing

Microbial analysis of soil, of top layer from selected sites of Area near Dahisar River Saika N. Esani University of Mumbai (Email – saikae@ymail.com) Abstract: soil samples were collected fortnightly from area near Dahisar River, A river in suburb of Mumbai. laboratory analysis started from July 2010 to September 2010. Total bacterial and fungal count were estimated by standard spread plate isolation. Isolated bacteria were subject to colony characterization and were estimated by their

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water, watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt, the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

The movie dirt was very informative, and showed me a lot about dirt that I have never known. I did not know that out of all of the known planets, Earth is the only one that has living and breathing dirt. Because of how many different elements there are to Dirt, it may be more alive than all of us. Dirt is the most important element. We need to protect and save Dirt because we depend on it for life. Another interesting fact is that in just a handful of dirt, there can be billions of microorganisms

How To Dethatch & Aerate A Lawn Tools needed: Garden hose, wooden matchsticks, iron rake, thatch rake, dethatching machine, garden fork, hand or machine aerator and leaf rake. The lawn must be dethatched if the thatch is more than 1/2" thick and compacted. To assess the level of compaction of the soil, water the lawn and note how quickly the water is absorbed in various areas of the lawn. The soil is compacted if the water does not absorb quickly. If a wooden matchstick cannot be easily inserted

2.3 Results and discussion 2.3.1 Physicochemical properties of soils Soil properties are shown in Table 2.1. These soils had a loamy texture with different contents of clay, sand and silt. pH values ranged from 4.45 to 7.73. TC was in the range of 1.6 to 8.37 % without significant amounts of TN and TS detected. TOC varied between 1.48 and 8.37% whilst DOC showed a wide range from 106 to 400 mg kg-1. CEC values ranged from 2.9 to 17.9 cmol kg-1. Concentrations of Fe oxide, Al oxide, and Mn oxide were

A soil ecosystem is composed of both living and non-living matter with a diversity of interactions (The Environmental Literacy Council, N.d.). This is a place where energy and matter are transformed and transported. Analyses that can be used to assess the functioning of land ecosystems is abiotic indicators, biological indicators, and atmospheric indicators. Abiotic indicators can include pH, moisture,and temperature. Soil temperature and moisture are important environmental factors that affect the
