Increased root mass and decreased rooting space leads to competition for available oxygen (Peterson et al., 1991b). Nutrients. Types of Vegetation and its Growth Stages 5. Environmental factors like temperature, light, water, nutrients, and soil affect plant growth from their germination to blooming. Edaphic Factors Affecting Root and Microbial Growth. Soil pH is important because it influences several soil factors affecting plant growth, such as (1) soil bacteria, (2) nutrient leaching, (3) nutrient availability, (4) toxic elements, and (5) soil structure. The soil qualities which affect crop growth are: Unfavorable soil conditions frequently overshadow everything else, and until corrected defeat any program of improve-ment. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. When roots are confined in a container that restricts their growth, the roots compete for essential resources. Introduction. Factor # 1. Olson JS (1958) Rates of succession and soil changes of southern Lake Michigan sand dunes. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetically-dictated characters are expressed in the plant. (For dry weight, weigh the plant . SOIL FACTORS Soil factors include soil texture, physical and chemical properties, field holding capacity, nutrient and so on (Yang et al., 2004). Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. These includethe following: Soil depth will determine root depth as well as species differences Raising soil pH from 5.40 to approximately 6.40 with 2,602 kg/ha of dolomitic limestone increased plant growth and soybean yields. 15.2 Experiment Design Plant growth is affected by several factors such as seed variety, amount of water, soil type, amount of light, temperature, humidity, and other. If the quality of the soil in the root zone of a landscape starts out reasonably high, certain cultural practices can help to maintain an environment conducive to root growth of ornamental plants.
