2019-3-28To amend clay soil, add builders sand and gypsum to create more air pockets and increase the soils drainage. You can also add organic matter, like compost or manure, to increase the nutrients in the soil. When laying your materials, aim for an equal mix of coarse sand and coarse organic material for optimum drainage and nutrients. ...

Soil is a combination of naturally occurring clays, clastic particles, and organic debri. Sand is bits of rock , mineral, and sometimes shell fragments that fall within a specified size range. Sand can be a component of soil but soil is never a co...
One of soil microbiologys most intriguing puzzles is how so many different bacterial species can coexist in small volumes of soil when competition theory predicts that less competitive species should decline and eventually disappear. We provide evidence supporting the theory that low pore connectivity caused by low water potential and therefore low water content increases the diversity of a ...

Hysteresis in the Soil Water Retention of a SandClay Mixture with Contact Angles Lower than Ninety Degrees Article in Vadose Zone Journal May 2015 with 111 Reads How we measure reads
Soils with smaller particles silt and clay have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity.
In other cases, the finer particles may be removed, while the sand-sized particles are accumulated to form mobile hills or ridges of sand. Even in the areas that retain a soil cover, the reduction of vegetation typically results in the loss of the soils ability to absorb substantial quantities of water.
Surprisingly often, people imagine that the proper way to improve a dense, clay soil is to add the opposite kind of mineral materialsand. After all, loamy soils, viewed as ideal garden soil, are a mixture of sand and clay. Unfortunately, when sand is added directly to clay, the result is something that more accurately resembles concrete.

Damp clay ready to have 20 sand kneaded in. When your clay is plastic enough to knead, take it out of the pillowcase. Some parts of the clay mass will be drier than others so some kneading will be necessary to form a consistent mass. Any parts that have dried too much to be kneaded will need to be put aside to be reprocessed later.
