Releasing clay and silt particles reduces the capacity for soil to absorb water and increases cross surface flow, accelerating soil erosion. In addition soil litter reduces wind erosion by preventing soil from losing moisture and providing cover preventing soil transportation. Organic matter accumulation also helps protect soils from wildfire ...
Mulch has many benefits for the soil and is an easy way to minimize garden maintenance. Mulch suppresses weeds, retains moisture in the soil, and adds nutrients back to the soil, too.
Professional soil scientists can also analyze samples of a soil to determine its shrink-swell capacity. [2] Expansive soils will form large cracks, in roughly polygonal shapes, on the surface of the soil during dry periods. [3] However, lack of these cracks does not mean a soil is not expansive. [7]
where water tables are shallow, the irrigation applications are reduced. As a result, the soil is no longer leached and soil salinity problems develop; stagnant water tables at the soil surface are known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many ...
Piling up leaves in an area in the garden, such as around trees or placing them carefully around plants as a form of mulch, is an easy way to put them to use and create a closed-loop system in ...
Master gardener Leimone Waite answers readers’ questions about plants, garden tools and their use, and gardening techniques.
The key characteristic of dry grasslands is that they have low-growing plants, causing the area to be quite open. They also have a mottled structure, which leads to a biome with sunny or semi-shaded areas. On top of that, their soil is relatively dry and nutrient-poor. There are, however, types of grasslands with a higher humus and nutrient ...
The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species.
