The pathogen A. euteiches does best in warm, wet soil conditions, but can survive at a range of moderate temperatures. Infection is most prevalent when host plants are in the seedling stage, and when temperatures are between 22 and 28 degrees Celsius. Because zoospores require water for mobility, standing water in the soil increases host ...
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
Like many larger farms, she plants cover crops in fields that would otherwise be bare between planting season, along with no-till practices. That keeps organic matter in the soil, helping to ...
A tallgrass prairie planting in Illinois. Prairie restoration is a conservation effort to restore prairie lands that were destroyed due to industrial, agricultural, commercial, or residential development. [1] The primary aim is to return areas and ecosystems to their previous state before their depletion. [2]
The rate at which a soil can absorb water depends on the soil and its other conditions. As a plant grows, its roots remove water from the largest pores (macropores) first. Soon the larger pores hold only air, and the remaining water is found only in the intermediate- and smallest-sized pores . The water in the smallest pores is so strongly held ...
Tilth is a physical condition of soil, especially in relation to its suitability for planting or growing a crop. Factors that determine tilth include the formation and stability of aggregated soil particles, moisture content, degree of aeration, soil biota, rate of water infiltration and drainage.
Illinois has received 3.41 inches of rain in the first half of July, 1.6 inches more than in the entire month of June, and leading to higher soil moisture across the state. Levels at 4 ...
Mesic soil is neither very wet nor very dry; plants that prefer this category can tolerate brief periods of flooding. [16] Dry soil is ideal for plants that can withstand long dry periods. Plantings chosen for rain gardens must be able to thrive during both extreme wet and dry spells, since rain gardens periodically swing between these two states.
