primary clay:- once formed from the parent rock deposited at origin, so less impurities,coarse particles,less humic acid , low plasticity& low shrinkage than 2ndry clay
secondry clay:- 2ndry clay are transported and formed, so more impurities, fine particles, more humic,higher plasticity and shrinkage.

ViviPrimary clay is formed directly from the weathering of rocks, while secondary clay is formed from the alteration of preexisting minerals. Primary clay is typically pure and lacks impurities, while secondary clay often contains impurities due to its formation process. Primary clay is usually found in close proximity to its source rock, while secondary clay can be found at varying distances from its source.

What is the difference between silt and clay?
Silt is larger in particle size than clay and feels gritty when dry, while clay is finer in particle size and feels sticky when wet. Silt is more fertile than clay and drains better, while clay holds more water and nutrients.
What is the difference between loamy and clay soil?
Clay soil has smaller particles than loamy soil, making it dense and easily compacted. Loamy soil is a mixture of sand, silt, and clay, and is considered the ideal soil type for gardening because it has good drainage and nutrient retention.
How does clay turn into limestone?
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
What is the difference between loam and clay?
Loam is a soil type that is a mixture of sand, silt, and clay, with good drainage and nutrient retention. Clay, on the other hand, is a type of soil with very fine particles that compact easily, has poor drainage, and tends to hold nutrients tightly. Clay soil is often denser and heavier than loam soil.
Does sandy soil or clay soil have bigger pore spaces?
Sandy soil typically has larger pore spaces compared to clay soil. This is because clay particles are much smaller and more tightly packed together, reducing the size of the pore spaces between them. This difference in pore space influences factors like water drainage, aeration, and root penetration in the soil.
