Organic matter:. Organic matter reduces the heat capacity and thermal conductivity of soil, increased absorptivity due to dark colour. When organic soils are dry they become warmer than mineral soil in summer and cooler. Agrometeorology :: Microclimate and Plant Growth. Micro Climate in Relation to Crop Production Soil Temperature Dynamics Soil temperature and its importance in crop production Soil temperature is an important environmental parameter for plant growth.
Variation in soil temperature is much more pronounced because of varying characteristics and composition of soil. When the water level inside the gas collecting test tube is higher than it is outside, is the O gas.

Temperature decreases will affect gas production and You can view more similar questions or ask a new question. Roots are less resistant to freezing than over wintering stems, but usually are adequately insulated by the soil.
Minimum temperatures occurring after a warm period can be especially harmful. The fluctuating temperatures cause the bark to split and disrupt the flow of nutrients from the roots. All plants will be injured or killed above maximum temperatures. Injury varies with species and the stage of plant development. Trees alter the microclimate of a site. Heat rays are reflected off the surface of leaves.
Also, temperature is modified by the reflective qualities of the surface covering in nonshaded areas. Asphalt and concrete absorb greater amounts of solar heat than turf and mulch, and these surfaces radiate more heat during the day and into the evening. Since cold air is denser than warm air, it flows down a slope, accumulates in the lowest area creating a frost pocket and displaces the warmer air upwards. Plants grown in a frost pocket may have cold damage. They will emerge and bloom later than those planted elsewhere in the garden.
Soil temperatures matter most if you are trying to encourage earlier blooms. Wind affects plant growth by increasing transpiration evaporation of water and carbon dioxide uptake and decreasing shoot elongation. High winds can deform plants and seriously damage them. Changes in wind speed are accompanied by changes in air temperature and humidity. Water runoff from paved surfaces, buildings and impervious subsoil strata accumulates in the pore spaces between soil particles reducing the oxygen, which is required for healthy roots to keep the plants supplied with sufficient nutrients for photosynthesis.
Also, compaction caused by high usage decreases soil pore space, affects drainage and impairs root growth. Do a microclimate analysis of your property. Which areas are expose to direct solar radiation? Prepare a map of the property indicating the various climatic conditions. Highlight the areas that have different microclimate conditions. This will help determine various plant habitats and horticultural opportunities. Having identified the various microclimates, one is able to plan and make changes to the landscape.
Awareness of how temperature and wind affect plant growth will facilitate selecting plants that are suited for the intended site.
