Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

effective soil is imperative in maximizing results in agriculture. Definition of Terms In this experiment the following terms are defined as such: Growth: the amount in inches that a plant grows vertically. Soil: a natural dirt with no added nutrients, only minerals already located in the soil will be accepted and used. Plant: In this case, a Californian Green Bean and Lettuce seeds. Methodology This report took an empirical/analytical stance on plant systems and their response by different…

An important chemical property of soil that can affect herbicide persistence is pH. Soil composition is a physical factor determined by the relative amounts of sand, silt, and clay in the soil (the soil texture), as well as by the organic-matter content. The types and abundance of soil microorganisms present in the soil make up the microbial aspects of the soil environment. Generally, soils high in clay, organic matter, or both have a greater potential for herbicide…

Boreal, Coniferous, and Deciduous Forests Boreal, deciduous, and coniferous forests each possess distinctive traits and soil characteristics. Forests soils give important contributions in nitrogen and phosphorus transformations. These transformations are dependable on the weather conditions of the forest and the type of vegetation it contains. Soil mineralogy and organic matter also play an important role in the nitrogen and phosphorus transformations on the forest floor. Boreal forests are…

utilized agricultural, animal and human residue as fertilizer (Howard, 1943, Food and Agriculture Organization, 1978). Many of these residues either were placed in pits or placed in heaps and allowed to rot for long period of time for the production of soil amendment. The first waste pits made out of stone and built outside the houses were found in Sumerian cities about 6000 years ago (Uhlig, H. 1976). India is characterized by a mosaic of distinct agro-ecosystem conditioned by its geological…

essential element for the plant’s survival. So required water is to be poured basing on the dryness of the soil. Check the soil for its wetness and if it is too wet then you can put water in alternative days. Even if you mulch the top layer of soil you didn’t require to pour water every day as mulching can prevent loss of water. Mulching Mulching means covering the top most layer of the soil in the pot for about 2 inches with dried leaves , twigs, grass clippings, saw scrap or any other…

hyperlinks used). In my opinion, utilizing cover crops and soil enrichment go hand in hand. These two techniques add a magnitude of benefits to the main source of agriculture, which is the soil. Cover crops are an excellent way to reduce soil erosion at the same time keeping the moisture requirements in balance to sustain all the micro bacteria which help break down the organic matter and releases nutrient back into the soil. Organic soil enrichment practices are the best way to reduce the…

He also adds on by stating that “Garden beds improve growing conditions for plants by lifting their roots above the soil”. Providing us with a simple but key explanation of why plants seem to grow faster if planted in garden beds. Hayes says that, “The soil in beds that are raised warms up earlier in the spring and is innovated by certain grasses and by the tree roots”. Recommending several steps to construct a raised garden bed. First…

anthropogenic activities result in heightened nutrient inputs into the environment (Foley et al. 2005), including land use. Land use legacies were compared in Phoenix between yards that were formerly farms and natural desert. The general hypothesis was that soil nutrient and C (carbon) pools would be the result of farming. Results showed residential yards that were formerly…

Tillage is the physical or mechanical agitation of the soil with tools and implements result in good tilth for better germination and subsequent growth of crops. Continuous practice of modifying the state of soil in order to provide favorable conditions for growth of crops is known as tillage addiction. Physical manipulation of soil is intended to destroy weeds, incorporate crop residues and amendments into soil, increase infiltration and reduce evaporation, prepare seedbed and break hard layers…
