Dry Gardening: A Modified Soil Sedimentation Method for a Garden with Gravelly Sandy Loam Soil
As part of overall goal to establish simple methods for dry gardening in Sustainable Agriculture, our goal this winter year 2021-2022 is the establishment a garden that is resilient to climate change (i.e retains moitsure from winter rains to be used in the 2022 growing season without additional watering or irrigation during summer). As a first step, we have determined the profile of soil texture (i.e.% gravel, sand, silt and clay) at multiple sites throughout the garden. For each site, we determine % gravel, sand, silt and clay in two soil horizons ( topsoil and subsoil). We used a modified method of soil sedimentation using mason glass jars to allow determination of gravel, sand, silt and clay separately. The modified method is illustrated in the Figure below: The results are shown in the table below: These results show that the soil throughout the garden is gravelly sandy loam and are consistent with public soil records for our area- due to glacial till. The percent clay ...
