Predicting Onset and Duration of Rainfall Seasons in Amukurat-Samuk Villages, Uganda

- September 25, 2022

For people in Amukurat-Samuk villages, the ability to predict or estimate the onset and duration of rainfall seasons is an essential skill for sustainable agriculture. One way is to use the migration of the tropical rainfall belt located along the equator, which migrates following the thermal equator (i.e. the location along the equator where solar radiation, and thus the temperatures are highest). Amukurat-Samuk villages are located at latitude 1.9185° N from the Equator, and longitude 33.3009° E of the meridian at Greenwich, England. The villages experience two rainy and two dry seasons as the thermal equator, and thus the tropical rainfall belt pass over the vilages twice each year; one when the thermal belt moves northwards and one when the thermal belt moves southwards. The duration of each rainy or dry season can vary greatly depending on local climatic conditions. During the years 2012 - 2013, we followed the migration of the tropical rainfall belt across Africa from So...

Splendor of Gardening on Bainbridge Island Washington: Further Evidence that Adding Sodium Chloride (Table Salt) Improves the Accuracy of Determining Percent Clay in the Soil Sedimentation Test for Soil Texture

- November 14, 2021

An essential aspect of sustainable agriculture is to develop resiliency to changes in climate. One aspect of this resiliency is to be able to capture and maintain soil moisture even during prolonged drought. Our goal this year (2021) is to capture the rain water from winter-Spring seasons into the soil of the garden for use in the Summer of 2022. We shall evaluate effectiveness in the summer by observing plant growth and determining whether or not they need watering from an external source. Since clay particles, due to their small size, have greater capacity to maintain/retain water/moisture, it is essential to accurately determine the percent clay, sand and silt in the soil; and thus, modify the soils in the garden accordingly. The profile soil in our area of Bainbridge Island, Washington, is considered to be gravelly sandy loam. We considered it neccessary to confirm the soil profile present in the specific site of the garden. We utilized soil sedimentation test by suspending so...

Dry Gardening: A Modified Soil Sedimentation Method for a Garden with Gravelly Sandy Loam Soil

- December 29, 2021

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 ...
