Soil hardness refers to the resistance of soil to deformation or penetration, which can vary based on factors such as moisture content, compaction, and soil composition. Harder soils, like clay, can be difficult to till and may require more effort to cultivate, while softer soils, like sandy soils, are generally easier to work with. Soil hardness is often measured using a penetrometer, which quantifies the force needed to penetrate the soil. Understanding soil hardness is important for agricultural practices, construction, and environmental assessments.
The experiment on sunflower growth affected by the hardness of the soil is likely to have greater reliability because soil properties can be controlled more easily than water conditions which can be influenced by various external factors. Additionally, soil hardness can be measured more objectively and consistently compared to the impact of water on cacti growth which can be affected by a wider range of variables.
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.

Pure materials, especially minerals, are measured on a hardness scale. There are three basic tests: indentation hardness, scratch hardness and rebound hardness. See Wikipedia
Uranite is not correct, if you mean URANINITE, it is ranges 5-6 hardness.

I've done them in 4 hours, but it depends on the placement and the hardness of the soil.
The hardness of water is mainly caused by the presence of minerals like calcium and magnesium. These minerals dissolve in water as it passes through rocks and soil, leading to increased hardness. Other factors that can contribute to water hardness include the pH level and the presence of other minerals like iron and manganese.
it is completely dependant on the soil above it and the water around it but it is normally pretty hard when damp, gets softer the wetter it is
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
flint is a type of quartz, so it has a hardness of about 7 on the mohs scale of hardness
what is the difference between Shore-A Hardness & Barcol Hardness
Tools such as rakes, hoes, shovels, and spades can be used to break up soil lumps in a garden or field. Implements such as a rototiller or garden fork can also be effective for larger areas. The choice of tool will depend on the size of the area and the hardness of the soil.
The hardness of conundrum is 9 on the Moh's hardness scale
Mohs hardness: 6 Brinell hardness: 196 MPa.
The Mohs hardness of sodium chloride is 2,5.
